Colorectal cancer is rising among younger adults and scientists are racing to uncover why | CNN

 — 

Nikki Lawson received the shock of her life at age 35.

A couple of years ago, she noticed that her stomach often felt irritable, and she would get sudden urges to use the restroom, sometimes with blood in her stool. She even went to the hospital one day when her symptoms were severe, she said, and she was told it might be a stomach ulcer before being sent home.

“That was around the time when Chadwick Boseman, the actor, passed away. I remember watching him on the news and having the same symptoms,” Lawson said of the “Black Panther” star who died of colon cancer at age 43 in August 2020.

“But at that time, I was not thinking ‘this is something that I’m going through,’ ” she said.

Instead, Lawson thought changing her diet would help. She stopped eating certain red meats and ate more fruits and vegetables. She began losing a lot of weight, which she thought was the result of her new diet.

“But then I went for a physical,” Lawson said.

Her primary care physician recommended that she see a gastroenterologist immediately because she had low iron levels.

“When I went and I saw my gastro, she said, ‘I’m sorry, I have bad news. We see something. We sent it off to get testing. It looks like it is cancer.’ My whole world just kind of blanked out,” Lawson said. “I was 35, healthy, going about my day, raising my daughter, and to get a diagnosis like this, I was just so shocked.”

Lawson, who was diagnosed with stage III rectal cancer, is among a growing group of colon and rectal cancer patients in the United States who are diagnosed at a young age.

The share of colorectal cancer diagnoses among adults younger than 55 in the US has been rising since the 1990s, and no one knows why.

Researchers at Dana-Farber Cancer Institute are calling for more work to be done to understand, prevent and treat colorectal cancer at younger ages.

In a paper published last week in the journal Science, the researchers, Dr. Marios Giannakis and Dr. Kimmie Ng, outlined a way for scientists to accelerate their investigations into the puzzling rise of colorectal cancer among younger ages, calling for more specialized research centers to focus on younger patients with the disease and for diverse populations to be included in studies on early-onset colorectal cancer.

Their hope is that this work will help improve outcomes for young colorectal cancer patients like Lawson.

Among younger adults, ages 20 to 49, colorectal cancer is estimated to become the leading cause of cancer-related deaths in the United States by 2030.

Lawson, now 36 and living in Palm Bay, Florida, with her 5-year-old daughter, is in remission and cancer-free.

The former middle school teacher had several surgeries and received radiation therapy and chemotherapy to treat her cancer. She is now being monitored closely by her doctors.

For other young people with colorectal cancer, “my words of hope would be to just stay strong. Just find that courage within yourself to say, ‘You know what, I’m going to fight this.’ And I just looked within myself,” Lawson said.

“I also have a very supportive family system, so they were definitely there for me. But it was very emotional,” she said of her cancer treatments.

“I remember crying through chemotherapy sessions and the medicine making you so weak, and my daughter was 4, and having to be strong for her,” she said. “My advice to any young person: If you see symptoms or you see something’s not right and you’re losing a lot of weight and not really trying to, go to see a doctor.”

Signs and symptoms of colorectal cancer include changes in bowel habits, rectal bleeding or blood in the stool, cramping or abdominal pain, weakness and fatigue, and weight loss.

A report released this month by the American Cancer Society shows that the proportion of colorectal cancer cases among adults younger than 55 increased from 11% in 1995 to 20% in 2019. Yet the factors driving that rise remain a mystery.

There’s probably more than just one cause, said Lawson’s surgeon, Dr. Steven Lee-Kong, chief of colorectal surgery at Hackensack University Medical Center in New Jersey.

He has noticed an increase in colorectal cancer patients in their 40s and 30s within his own practice. His youngest patient was 21 when she was diagnosed with rectal cancer.

“There is a phenomenon of decreasing overall colorectal cancer rates in the population in general, we think because of the increase in screening for particularly for older adults,” Lee-Kong said. “But that doesn’t really account for the overall increase in the number of patients younger than, say, 50 and 45 that are developing cancer.”

Some of the factors known to raise anyone’s risk of colorectal cancer are having a family history of the disease, having a certain genetic mutation, drinking too much alcohol, smoking cigarettes or being obese.

“They were established as risk factors in older cohorts of patients, but they do seem to be also associated with early-onset disease, and those are things like excess body weight, lack of physical activity, high consumption of processed meat and red meat, very high alcohol consumption,” said Rebecca Siegel, a cancer epidemiologist and senior scientific director of surveillance research at the American Cancer Society, who was lead author of this month’s report.

“But the data don’t support these specific factors as solely driving the trend,” she said. “So if you have excess body weight, you are at a higher risk of colorectal cancer in your 40s than someone who is average weight. That is true. But the excess risk is pretty small. So again, that is probably not what’s driving this increase, and it’s another reason to think that there’s something else going on.”

Many people who are being diagnosed at a younger age were not obese, including some high-profile cases, such as Broadway actor Quentin Oliver Lee, who died last year at 34 after being diagnosed with stage IV colon cancer.

“Anecdotally, in conferences that I’ve attended, that is the word on the street: that most of these patients are very healthy. They’re not obese; they’re very active,” Siegel said, which adds to the mystery.

“We know that excess weight increases your risk, and we know that we’ve had a big increase in body weight in this country,” she said. “And that is contributing to more cancer for a lot of cancers and also for colorectal cancer. But does it explain this trend that we’re seeing, this steep increase? No, it doesn’t.”

Yet scientists remain divided when it comes to just how much of a role those known risk factors – especially obesity – play in the rise of colorectal cancer among adults younger than 55.

Even though the cause of the rise of colorectal cancer in younger adults is “still not very well understood,” Dr. Subhankar Chakraborty argues that dietary and lifestyle factors could be playing larger roles than some would think.

“We know that smoking, alcohol, lack of physical activity, being overweight or obese, increased consumption of red meat – so basically, dietary factors and environmental and lifestyle factors – are likely playing a big role,” said Chakraborty, a gastroenterologist with The Ohio State University Comprehensive Cancer Center.

“There are also some other factors, such as the growing incidence of inflammatory bowel disease, that may also be playing a role, and I think the biggest factors is most likely the diet, the lifestyle and the environmental factors,” he said.

It has been difficult to pinpoint causes of the rise of cases in younger ages because, if someone has a polyp in their colon for example, it can take 10 to 15 years to develop into cancer, he says.

“During that, all the way from a polyp to the cancer stage, the person is exposed to a variety of things in their life. And to really pinpoint what is going on, we would need to follow specific individuals over time to really understand their dietary patterns, medications and weight changes,” Chakraborty said. “So that makes it really hard, because of the time that cancer actually takes to develop.”

Some researchers have been investigating ways in which the rise in colorectal cancer among younger adults may be connected to increases in childhood obesity in the US.

“The rise in young-onset colorectal cancer correlates with a doubling of the prevalence of childhood obesity over the last 30 years, now affecting 20% of those under age 20,” Dr. William Karnes, a gastroenterologist and director of high-risk colorectal cancer services at the UCI Health Digestive Health Institute in California, said in an email.

“However, other factors may exist,” he said, adding that he has noticed “an increasing frequency of being shocked” by discoveries of colorectal cancer in his younger patients.

There could be correlations between obesity in younger adults, the foods they eat and the increase in colorectal cancers for the young adult population, said Dr. Shane Dormady, a medical oncologist from El Camino Health in California who treats colorectal cancer patients.

“I think younger people are on average consuming less healthy food – fast food, processed snacks, processed sugars – and I think that those foods also contain higher concentrations of carcinogens and mutagens, in addition to the fact that they are very fattening,” Dormady said.

“It’s well-publicized that child, adolescent, young adult obesity is rampant, if not epidemic, in our country,” he said. “And whenever a person is at an unhealthy weight, especially at a young age, which is when the cells are most susceptible to DNA damage, it really starts the ball rolling in the wrong direction.”

Yet at the Center for Young Onset Colorectal and Gastrointestinal Cancers at Memorial Sloan Kettering Cancer Center, researchers and physicians are not seeing a definite correlation between the rise in colorectal cancer among their younger adult patients and a rise in obesity, according to Dr. Robin Mendelsohn, gastroenterologist and co-director of the center, where scientists and doctors continue to work around the clock to solve this mystery.

“When we looked at our patients, the majority were more likely to be overweight and obese, but when we compare them to a national cohort without cancer, they’re actually less likely to be overweight and obese,” she said. “And anecdotally, a lot of the patients that we see are young and fit and don’t really fit the obesity profile.”

That leaves many oncologists scratching their heads.

Some scientists are also exploring whether genetic mutations that can raise someone’s risk for colorectal cancer have played a role in the rise of cases among younger adults – but the majority of these patients do not have them.

Karnes, of UCI Health, said “it is unlikely” that there has been an increase in the genetic mutations that raise the risk of colorectal cancer, “although, as expected, the percentage of colorectal cancers caused by such mutations, e.g., Lynch syndrome, is more common in people with young-onset colorectal cancer.”

Lynch syndrome is the most common cause of hereditary colorectal cancer, causing about 4,200 cases in the US per year. People with Lynch syndrome are more likely to get cancers at a younger age, before 50.

“In my practice and in the medical community, the oncologic community, I don’t think there’s any proof that genetic syndromes and gene mutations that patients are born with are becoming more frequent,” El Camino Health’s Dormady said. “I don’t think the inherent frequency of those mutations is going up.”

The tumors of younger colorectal cancer patients are very similar to those of older ones, said Mendelsohn at Memorial Sloan Kettering Cancer Center.

“So then, the question is, if they’re biologically the same, why are we seeing this increasingly in younger people?” she said. “About 20% may have a genetic mutation, so the majority of patients do not have a family history or genetic predisposition.”

Therefore, Mendelsohn added, “it’s likely some kind of exposure, whether it be diet, medication, changing microbiome,” that is driving the rise in colorectal cancers in younger adults.

That rise “has been something that’s been on our radar, and it has been increasing since the 1990s,” Mendelsohn said. “And even though it is increasing, the numbers are still small. So it’s still a small population.”

Dormady, at El Camino Health, said he now sees more colorectal cancer patients in their early to mid-50s than he did 20 years ago, and he wonders whether it might be a result of colorectal cancer screening being easier to access and better at detecting cancers.

“The first thing to consider is that some of our diagnostic modalities are becoming better,” he said, especially because there are now many at-home colorectal cancer testing kits. Also, in 2021, the US Preventive Services Task Force lowered the recommended age to start screening for colon and rectal cancers from 50 to 45.

“I think you have a subset of patients who are being screened earlier with colonoscopies; you have advancing technology where we can potentially detect tumor cell DNA in the stool sample, which is leading to earlier diagnosis. And sometimes that effect will skew statistics and make it look like the incidence is really on the rise, but deeper analysis shows you that part of that is due to earlier detection and more screening,” he said. “So that could be one facet of the equation.”

Overall, pinpointing what could be driving this surge in colorectal cancer diagnoses among younger ages will not only help scientists better understand cancer as a disease, it will help doctors develop personalized risk assessments for their younger patients, Ohio State University’s Chakraborty said.

“Because most of the people who go on to develop colorectal cancer really have no family history – no known family history of colon cancer – so they would really not be aware of their risk until they begin to develop symptoms,” he said.

“Having a personalized risk assessment tool that will take into account their lifestyle, their environmental factors, genetic factors – I think if we have that, then it would allow us hopefully, in the future, to provide some personalized recommendations on when a person should be screened for colorectal cancer and what should be the modality of screening based on their risk,” he said. “Younger adults tend to develop colon cancer mostly in the left side, whereas, as we get older, colon cancer tends to develop more on the right side. So there’s a little difference in how we could screen younger adults versus older adults.”

Ozempic prescriptions can be easy to get online. Its popularity for weight loss is hurting those who need it most | CNN



CNN
 — 

Telehealth and social media are playing a significant role in driving demand for Ozempic, a prescription drug that treats Type 2 diabetes, experts told CNN. The current drug shortage has limited access for patients with diabetes who rely on it to control their blood sugar.

Digital health companies make medications like Ozempic easier to get by providing prescriptions online. Many advertise quick and easy — sometimes same-day — access.

“Anecdotally, it’s almost easier to get medication [via digital health companies],” said Dr. Disha Narang, endocrinologist and director of obesity medicine at Northwestern Medicine, Lake Forest Hospital. “But not always the safest.” People who put in average weights on the online intake forms were still offered the antidiabetic drug, Narang told CNN.

In part because of Ozempic’s popularity, the prescription weight loss drug market has grown significantly, according to MarketData Enterprises, an independent market research and consulting firm. The market surpassed forecasters’ expectations for 2022 and is expected to become a nearly $2 billion industry in 2023.

WeightWatchers is also tapping into the telehealth prescription drug space. Last week, the company bought telehealth subscription service Sequence, which helps connect patients to doctors who can prescribe weight loss and diabetes drugs.

“At the start of 2022, these companies weren’t marketing this stuff,” Narang said, noting advertising around Ozempic took off in 2022. “I think we really need to start questioning our ethics around this.”

There are few across-the-board requirements when it comes to digital health companies’ intake processes, Dr. Bree Holtz, an associate professor at Michigan State University studying telemedicine, told CNN. Once a patient fills out the required forms online, information gets transferred to an in-state provider who can write the prescription. Some companies require that the patient hop on a video or phone call with the provider — others don’t require either.

“It’s a little scary that you can just wake up and get these appointments in — or these pharmaceuticals — and you’re not being cared for,” said Holtz.

Telehealth has been a game changer in providing access to health care, particularly during the pandemic. And especially for people living in places where high-quality primary care is not available, direct to consumer telehealth services can help fill a gap, said Dr. Laurie Buis, associate professor in the Department of Family Medicine at the University of Michigan, whose research focuses on digital health.

When patients begin to seek selective treatment from selective providers, however, Buis says it opens the door to problems like fragmented care or abuse. Telehealth providers may not have access to a patient’s full medical history and may be less able to provide holistic care that a primary care physician otherwise could.

“I have no doubt that some of these services are doing a good job,” said Buis. “There are also services that don’t take it quite as seriously. And that’s of concern.”

The US Food and Drug Administration first announced that Ozempic was in shortage last August. Supply will likely be strained through mid-March, according to the FDA drug shortages database.

Ozempic prescriptions in the US reached an all-time high in the last week of February, with over 373,000 prescriptions filled, according to a J.P. Morgan analysis of IQVIA data shared with CNN. That’s an increase of 111%, compared with the same week in 2022.

Of these, more than half were new prescriptions, according to a CNN review of J.P. Morgan’s analysis.​​

With many patients relying on Ozempic for diabetes treatment, providers like Narang are scrambling to figure out what alternatives to put their patients on.

“We’re getting messages daily about patients not being able to get their own medication,” Narang said. “It’s been tough for patients and providers alike.”

Ozempic currently holds more than 40% of the US market share of glucagon-like peptide 1 (GLP-1) agonists — a class of drugs that mimic an appetite-regulating hormone — according to analysis from J.P. Morgan. These drugs work by stimulating the release of insulin, which helps lower blood sugar. They also slow the passage of food through the gut.

Ozempic has grown quickly in popularity since it was first put on the market in 2018. The drug has safely and successfully been used to help diabetics improve blood sugar levels and put diabetes into remission, Narang told CNN. Ozempic is the most potent of all the GLP-1 medications, she said.

Behind the brand name Ozempic is the medication semaglutide. While Ozempic is used primarily to treat Type 2 diabetes, another drug by the name Wegovy — also semaglutide — is approved specifically for chronic weight management.

Although approved by the FDA in 2021, Wegovy was not readily available through most of last year, according to Narang, so people turned to Ozempic. According to the FDA drug shortages database, Wegovy was undersupplied starting at the end of last March but came back in stock earlier this year.

Social media buzz around the two drugs took off at the start of 2023. Celebrities shared their testimonies about how semaglutide helped them shed unwanted pounds. Elon Musk, for example, publicly credited Ozempic and Wegovy in part for his weight loss.

#Ozempic and #Wegovy have been “extremely popular” over the last few months on TikTok, according to company analytics.

The use of Ozempic and Wegovy for short-term weight loss has resulted in real consequences for patients who need the drugs most for diabetes treatment and chronic weight management, said Narang. For example, some insurance companies in the past have reportedly refused to cover Wegovy, one calling it a “vanity drug.”

Both drugs are intended for long-term use, not for short-term weight loss. Their appetite-regulating effects wear off quickly after you stop taking them.

“This is not meant to be a medication to take off your last five or 10 pounds to get ready for an event or something like that. It’s not for use of three or four weeks,” Narang said. “When we think about weight management, we’re thinking about the next 25 years of someone’s life.”

Go ahead and sigh. It’s good for you | CNN

Editor’s Note: Sign up for CNN’s Stress, But Less newsletter. Our six-part mindfulness guide will inform and inspire you to reduce stress while learning how to harness it.



CNN
 — 

Sighs — those long, exhales of breath often accompanied with a bit of a whimper — have long been seen as a sigh of melancholy, frustration or even despair, leading us to ask the sighing person, “What’s wrong?”

A recent study turns that notion on its head. Instead of seeing sighs as sadness or exasperation, recognize them for what they accomplish — stress relief, said Dr. David Spiegel, a professor of psychiatry and behavioral sciences and director of the Center on Stress and Health at Stanford University School of Medicine.

“People think taking a deep breath is the way to ease stress,” he said. “But it turns out that exhaling slowly is a better way to calm yourself.”

You breathe without thinking, but what’s the best way to inhale and exhale while you’re thinking about it — especially if the goal is better health?

To find out, Spiegel and his team conducted a study, published earlier this year in Cell Reports Medicine, comparing three different types of deep breathing with mindfulness meditation. The goal was to see whether a breathing technique might be as effective as meditation in reducing stress.

Researchers sorted 114 people into four groups and asked them to practice mindful meditation or one breathing exercise — box breathing, cyclic hyperventilation or cyclic sighing — for five minutes a day for 28 days.

Box breathing requires a person to breathe in, hold, breathe out, and pause equally (like the sides of a box) to the count of four. In cyclic hyperventilation, a person breathes in deeply and out quickly — the inhalations are much longer than the exhalations.

In cyclic sighing, a person inhales through the nose until the lungs are halfway full, then pauses briefly. The lungs are then filled completely with another breath, and then the breath is slowly exhaled out the mouth.

“You want the exhalation to be like twice as long as the inhalation,” said Spiegel, who is also the medical director of Stanford’s Center for Integrative Medicine.

The team then assessed mood, anxiety levels and sleep behavior after each breathing or meditation session, as well as respiratory and heart rate variability.

Sleep was not affected, the study found. All forms of breathing and meditation increased positive mood and improved anxiety. However, breathing was more effective than meditation, with cyclic sighing making the most difference, the study found.

“Cyclic sighing is a pretty rapid way to calm yourself,” Spiegel said. “Many people can do it about three times in a row and see immediate relief from anxious feelings and stress.”

While interesting, the study was small, and doesn’t take away from all the work in progress on the benefits of any form of breath work or meditation, said stress management expert Dr. Cynthia Ackrill, former editor for Contentment Magazine, produced by the American Institute of Stress.

“We know that bringing your attention to any form of breath work starts the process of awareness that feeds mindfulness and its benefits,” she said in an email. “As long as we are all experimenting with mind-body connections with open minds and finding something that calms us, yay!”

Deliberately taking a slow, deep breath, holding it, and then letting it out slowly activates the parasympathetic nervous system, responsible for controlling how the body rests and digests, Spiegel said. Heart rate slows, blood pressure drops, digestion is improved and the mind begins to wind down and relax.

Contrast that to a sharp inhale of breath, which you might take when you’re afraid or in danger. That triggers the sympathetic nervous system, responsible for getting us ready to fight or flee.

“The brake works more healthfully than the accelerator here,” Spiegel said. “By slowing your heart when you do this cyclic sighing you’re immediately soothing yourself in a rather rapid way.”

“We believe breathing is a pathway into mind-body control,” he added. “It’s part of the autonomic system like digestion and your heartbeat, but unlike those body functions, you can easily regulate breathing.”

This isn’t the first study on the topic. Researchers have been busy trying out different methods to see which calms the body the quickest, longest, or most deeply, and which gives the most health benefits.

Many breathing methods are borrowed from ancient yoga, martial arts and meditation practices. For example, the 4-7-8 method, in which you breathe in while counting to four counts, hold the breath for seven counts and exhale while counting to eight, is based on pranayama, an ancient form of breath regulation practiced in Hinduism and Buddhism.

There are all sorts of variations: The 4-4 method, in which you breathe in and out for a count of four; the 6-6 method, in which you breathe in and out to the count of six; alternate nostril breathing and many more.

Diaphragmatic breathing, also known as belly breathing, has been practiced for millennia by practitioners of tai chi and yoga. It requires the breath to be inhaled so deeply that it fills the abdomen — you can tell if you’re doing it right by watching your stomach rise and fall.

A 2020 meta-analysis found diaphragmatic breathing is especially beneficial for patients with chronic obstructive pulmonary disease (COPD), and might be helpful in reducing stress and anxiety and treating constipation, eating disorders, high blood pressure and migraines.

You don’t have to sigh or breathe loudly to get the benefits of any forms of breathing, Ackrill said.

“These don’t need to be audible sighs, you can just change the rate quietly,” she said. “And you just might get the people around you to slow down their breathing as well.”

So go ahead. Take a deep breath and let it out in a huge, long, slow sigh. And if anyone does ask what’s wrong, you can smile and say, “Absolutely nothing! I’m just releasing my stress.”

Top Risk Factor to Good Health Is Probably Not What You Think

March 7, 2023 — If you think the biggest risk factor to good health is smoking or genetics, think again. 

According to Stephen Kopecky, MD, a preventive cardiologist at the Mayo Clinic, “nutrition is now the number one cause of early death and early disease in our country and the world.” Moreover, he says that while having genes for disease will increase your risk by 30% to 40%, having a bad lifestyle for disease will increase your risk by 300% to 400%.

About 20 years ago, Kopecky says, the cause of death worldwide changed from infection to non-infection (like non-communicable diseases). “In those last 20 years, that’s grown in terms of what kills us and what gets us sick,” he says. “The three big non-communicable diseases are heart disease, cancer, and rapidly rising is Alzheimer’s. But there’s also diabetes, obesity, and high blood pressure — all those things are also related to diet.”

Forty-eight-year-old James, of Fredericksburg, VA, knows this all too well. James asked that his last name not be printed, to protect his privacy. For the last 30 years, he’s been managing type 1 diabetes and complications of insulin resistance, along with high blood pressure, high cholesterol, thyroid disease, and low testosterone. As a former Division 1 college athlete, James exercised regularly and ate what he believed to be a responsible diet.

“Those weirdos in the gym at 5 a.m. who eat chicken salads for every lunch? Yeah, that’s me,” says James. 

But he went from a playing weight of 202 pounds to 320 pounds, despite continuing to lift weights and do cardiovascular exercise at least 5 days a week. “Whenever I went to the doctor and stepped on the scale, I got skeptical looks when I made claims of ‘exercising and eating right.’ In all honesty, I thought I was,” says James, noting he followed a low-carb, high-protein diet. “But I didn’t count calories or consider the impact of fat on my already insulin-resistant body,” he says.

After visiting many health professionals, James finally found success with Nancy Farrell Allen, a registered dietitian nutritionist.

Previous doctors applauded his diet, but Allen explained that his insulin resistance was linked to the amount of fat James consumed. “The more fat in my system, the more insulin I needed to inject,” he says. “The more insulin I injected, the more weight I’d gain. The more weight I’d gain, the more insulin I’d inject, continuing this regrettable cycle.” 

Allen suggested he shift his diet to a more balanced approach, with a strict eye on fat. “She completely changed my way of thinking about food, broke my belief that all carbs are bad, helped me identify my daily caloric needs, and focused me on eating a balanced diet enriched with fiber,” says James, who then lost 45 pounds in 3 months. “I found myself having more energy, sleeping better, focusing better, and taking less insulin than I had in nearly 20 years,” he says. 

Another patient, Sheila Jalili of Miami, took a proactive approach to her health when she turned 40, getting some tests and lab work done for a baseline comparison. “My BMI was around 20, I exercise every day, and I don’t have any diseases in my family,” Jalili says, noting everything checked out fine. 

She continued her annual checkups and tests, noticing her triglycerides and cholesterol numbers increasing. When her cholesterol reached alarming levels and her triglycerides skyrocketed to 1,230, she met with Kopecky, the Mayo Clinic cardiologist, who prescribed fish oil and asked about her diet. Jalili started tracking what she ate and did an exhaustive review of her fridge contents, noting the sodium levels, cholesterol levels, and fat levels in the foods. 

To her surprise, she discovered she ate a lot of unhealthy carbs and fats. “I went into overload. I changed everything. I did so much research,” she says. After 42 days of eating extremely healthy, she dropped her total cholesterol by about 100, halved her HDL, and reduced her triglycerides from 1,238 to 176.

A bad lifestyle often starts with what you eat — and what you don’t. Even if you think you’re eating healthy, you might want to revisit your diet. In particular, reconsider ultra-processed foods (like doughnuts, hot dogs, and fast-food burgers). Though convenient and affordable, they’re inflammatory and, over time, can cause many health issues.

“It bothers our tissues, our heart, our arteries, our brains, our pancreas, our liver, and our lungs, and that leads to disease,” Kopecky says. “It could be in the brain with Alzheimer’s, the heart with coronary artery disease, or cancers elsewhere.”

Ideally, you’d immediately overhaul an unhealthy diet. But that’s not a reality for most people. Making sweeping changes all at once can feel overwhelming. Take small steps instead.

Baby-Step Your Way to a Healthier Diet

Before making any dietary changes, Selvi Rajagopal, MD, MPH, advises having a conversation with your health care provider to figure out your specific health status. Rajagopal, assistant professor of medicine at Johns Hopkins University, says that, generally speaking, everyone will benefit from eating a balanced, healthy diet filled with a variety of nutrient-rich foods. 

That includes fruits, vegetables, whole grains, lean protein, low-fat/fat-free dairy, and healthy fats. However, talking with your doctor can help you identify any specific nutrient deficiencies, health issues, and lifestyle factors that need to be addressed. Then you can devise a healthy eating plan that works specifically for your needs.

Revamp how you organize your refrigerator. Most refrigerators put two opaque drawers labeled “Fruits” and “Vegetables” at the bottom, where you’re least likely to see them. Kopecky advises moving your produce to eye level and put the less-healthy options in those bottom drawers. “When we open the fridge, that’s what we see, and that’s what we tend to eat,” he says.

Change your perspective. “There isn’t one healthy weight or one healthy size,” says Rajagopal. Don’t aim for a number on the scale or a certain BMI or certain clothing size. Every body is different, not only in shape and size, but in health risk factors. Also, many people feel really overwhelmed trying to “be healthy.” Rajagopal says, “Healthy is just trying to do something to improve your health, and that improvement can be really small.”

Understand how to read food labels. Allen takes every patient to the grocery store to read and understand food labeling and to highlight different foods. She shares the guidelines below with her patients. 

  • Fat: Low-fat foods contain 3 grams of fat or less per serving.
  • Sugar: Four grams equal 1 teaspoon. When a serving of sugar lists 12 grams of sugar in a 2/3-cup serving, that means it contains roughly 3teaspoonsof sugar.
  • Fiber: A naturally high-fiber food can contain about 5 grams of fiber per serving. 
  • Sodium: A low-sodium food contains less than or equal to 140 milligrams of sodium per serving. 
  • Protein: Seven grams of protein equal about 1 ounce of protein. 

This approach is particularly important as the FDA is exploring a change in which foods can be labeled as healthy. The agency in September unveiled a proposed rule to try and counter the fact that, as the agency claims, more than 80% of people in the U.S. aren’t eating enough vegetables, fruit, and dairy. And most people consume too much added sugars, saturated fat, and sodium.

Under the proposed rule, in order to be labeled “healthy” on food packaging, products must contain “a certain meaningful amount” of food from at least one of the food groups or subgroups (e.g., fruit, vegetable, dairy, etc.) recommended by the agency’s dietary guidelines.

They must also stick to specific limits for certain nutrients, such as saturated fat, sodium, and added sugars. 

Breakfast cereals, for example, would need to contain 0.75 ounces of whole grains and contain no more than 1 gram of saturated fat, 230 milligrams of sodium, and 2.5 grams of added sugars to qualify, the agency said.

Don’t fear carbs or fat! Your body needs both to survive, as carbs help fuel your body and fat helps your body absorb fat-soluble nutrients like vitamins A, D, and E. But not all carbs or fats are equal. Choose complex carbohydrates found naturally in plant-based foods (like fruits, vegetables, and whole grains) over simple carbohydrates often found in processed foods (like white bread, enriched pasta, and white rice). 

Similarly, strive to include healthy, unsaturated fats (including polyunsaturated and monounsaturated fats) found in foods such as fatty fish, vegetable oils, avocadoes, and some seeds and nuts. Avoid foods with unhealthy saturated and trans fats found primarily in animal products (such as meat, eggs, high-fat dairy) and highly processed foods (frozen pizza and microwave popcorn). “Having a baseline understanding of what this means makes you a much savvier consumer,” says Rajagopal, who suggests going to the U.S. Department of Agriculture’s website to learn about these food components. 

Adopt healthier cooking methods. Maybe you’re buying healthy foods but preparing them in unhealthy ways. That lean, skinless chicken breast just got a lot less healthy once you breaded it, deep-fried it, and smothered it with cheese. Allen suggests lighter, leaner techniques such as baking, roasting, grilling, and steaming. “Frying, sautéing, breading, au gratin, buttery, and Alfredo all add additional calories to burn off,” says Allen.

Start small. Eliminate the all-or-nothing thinking, such as, “I want to cut out all sugar” or “I want to cook all my meals at home.” 

If you’ve been eating sugar your whole life or eating dinner out 5 nights a week, eliminating this bad habit at once is a huge undertaking. Instead, start small. For instance, reduce one sugary food item you frequently eat. 

“Maybe it’s soda,” says Rajagopal. “Maybe you go from four cans of soda a day to two cans. Make one change and see how it goes for a week or two.” 

Ditto for cooking — aim to add one more home-cooked meal a week rather than trying to cook at home 7 days a week. She also advises bringing in an accountability buddy to help you stay on track. 

Take one bite. “If you take a bite of a ground meat or sausage and replace that with a bite of something that’s a little healthier — like black beans or a vegetable — then, after doing this for a couple of years, that actually reduces your risk of heart attack and reduces your risk in the long-term of cancers and Alzheimer’s,” advises Kopecky. “Literally one bite difference.”

By making small, consistent changes, they can have a big impact over time. Pick one tip that resonates most, implement it, and stick to it until it becomes second nature. Once mastered, move on to another tip, building on that foundation of success.

Bempedoic acid improved heart health in patients who can’t tolerate statins, study finds | CNN



CNN
 — 

Bempedoic acid may be an alternative for people who need to lower their cholesterol but can’t or won’t take statins, according to a large study published Saturday in the New England Journal of Medicine.

Statins are the most commonly prescribed cholesterol-lowering drugs that help lower what’s known as the “bad” cholesterol, or low-density lipoprotein (LDL) cholesterol in the blood; more than 90% of adults who take a cholesterol-lowering medicine use a statin, according to the US Centers for Disease Control and Prevention.

Statins are considered safe and effective, but there are millions of people who cannot or will not take them. For some people it causes intense muscle pain. Past research has shown anywhere between 7% and 29% of patients who need to lower cholesterol do not tolerate statins, according Dr. Steven Nissen, a cardiologist and researcher at the Cleveland Clinic and co-author of the new study.

“I see heart patients that come in with terrible histories, multiple myocardial infarction, sometimes bypass surgery, many stents and they say, ‘Doctor, I’ve tried multiple statins, but whenever I take a statin, my muscles hurt, or they’re weak. I can’t walk upstairs. I just can’t tolerate these drugs,’ ” Nissen said. “We do need alternatives for these patients.”

Doctors have a few options, including ezetimibe and a monoclonal antibody called a proprotein convertase subtilisin/kexin type 9, or PCSK9 inhibitors for short.

Bempedoic acid, sold under the name Nexletol, was designed specifically to treat statin-intolerant patients. The FDA approved it for this purpose in 2020, but the effects of the drug on heart health had not been fully assessed until this large trial. The new study was funded in part by Esperion Therapeutics, the maker of Nexletol.

For the study, which was presented Saturday at the American College of Cardiology’s Annual Scientific Session with the World Congress of Cardiology, Nissen and his colleagues enrolled 13,970 patients from 32 countries.

All of the patients were statin intolerant, typically due to musculoskeletal adverse effects. Patients had to sign an agreement that they couldn’t tolerate statins “even though I know they would reduce my risk of a heart attack or stroke or death,” and providers signed a similar statement.

The patients were then randomized into two groups. One was treated with bempedoic acid, the other was given a placebo, which does nothing. Researchers then followed up with those patients for up to nearly five years. The number of men and women in the trial were mostly evenly divided, and most participants, some 91%, were White, and 17% were Hispanic or Latino.

The drug works in a similar way that statins do, by drawing cholesterol out of a waxy substance called plaque that can build up in the walls of the arteries and interfere with the blood flow to the heart. If there is too much plaque buildup, it can lead to a heart attack or stroke.

But bempedoic acid is only activated in the liver, unlike a statin, so it is unlikely to cause muscle aches, Nissen said.

In the trial, investigators found that bempedoic acid was well-tolerated and the percent reduction in the “bad” cholesterol was greater with bempedoic acid than placebo by 21.7%.

The risk of cardiovascular events – including death, stroke, heart attack and coronary revascularization, a procedure or surgery to improve blood flow to the heart – was 13% lower with bempedoic acid than with placebo over a median of 3.4 years.

“The drug worked in primary and secondary prevention patients – that is, patients that had had event and patients who were very high risk for a first event. There were a lot of diabetics. These were very high risk people,” Nissen said. “So the drug met its expectations and probably did a lot better than a lot of people thought it would do.”

In the group that took bempedoic acid, there were a few more cases of gout and gallstones, compared with people who took a placebo.

“The number is small, and weighing that against a heart attack, I think most people would say, ‘OK I’d rather have a little gout attack,’ ” Nissen said.

Bempedoic acid had no observed effect on mortality, but that may be because the observation period was too short to tell if it had that kind of impact. Earlier trials on statins showed the same; it was only after there were multiple studies on statins that scientists were able to show an impact on mortality.

Dr. Howard Weintraub, a cardiologist at NYU Langone Health who did not work on this study, said that while he knows some people will not consider a medication successful unless it reduces mortality, he thinks that is short-sighted.

“I think there’s more to doing medicine then counting body bags,” Weintraub said.”Preventing things that can be life changing, crippling, and certainly change your quality of life forever going forward, and your cost of doing things going forward, I think is a good thing.”

He was pleased to see the results of this trial, especially since the people in this study are often what he called “forgotten individuals” – the millions who could benefit from lowering their cholesterol, but can’t take statins.

“It’s not like their LDL was 180 or 190 or 230, their LDL was 139. This is about average in our country,” Weintraub said. He said often doctors will just tell those patients to watch their diet, but he thinks this suggests they would benefit from medication.

“Both groups primary and secondary prevention got benefit, which I think is impressive with the modest amount of LDL reduction,” Weintraub said.

There are some limitations to this trial. It was narrowly focused on patients with a known statin intolerance. Nissen said the trial was not designed to determine whether bempedoic acid could be an alternative to statins.

“Statins are the gold standard. They are the cornerstone. The purpose of this study was not to replace statins, but to allow an alternative therapy for people who simply cannot take them,” Nissen said.

Bempedoic acid is a much more expensive drug than a statin. There are generic versions of statins and some cost only a few dollars. Bempedoic acid, on the other hand, has no generic alternative and a 30-day supply can cost more than $400, according to GoodRx.

“I think what insurance companies need to recognize that even though this drug is going to cost more than statins, having a heart attack or a stroke or needing a stent is expensive. A 23% reduction in (myocardial infarctions) is a considerable reduction,” Weintraub said.

In an editorial in the New England Journal of Medicine that accompanied the study, Dr. John H. Alexander, who works in the division of cardiology at Duke Clinical Research Institute, Duke Health, Durham said that doctors should take these results into consideration when treating patients with high cholesterol who can’t take statins.

“The benefits of bempedoic acid are now clearer, and it is now our responsibility to translate this information into better primary and secondary prevention for more at-risk patients, who will, as a result, benefit from fewer cardiovascular events,” Alexander wrote.

Dr. Manesh Patel, a cardiologist and volunteer with the American Heart Association who was not a part of the study, said that providers are already prescribing bempedoic acid for some patients, but with this new research, he thinks they will quickly be used with more statin-intolerant patients.

“We continue to see that if we can lower your LDL significantly, we improve people’s cardiovascular health. And so we need as many different arrows in our quiver to try to get that done,” Patel said.

Heart disease is the No. 1 killer for men and women in the world. One person dies every 34 seconds in the US from cardiovascular disease, according to the CDC. About 697,000 people in the US died from heart disease in 2020 alone – about the same number as the population of Oklahoma City.

“Given the number of people that are eligible for statins, which are tens of millions of patients already, the number of people who cannot tolerate statins is in the millions,” Nissen said. “This is a big public health problem and I think we’ve come up with something that directly addresses this.”

How to stop dieting, according to people who have done it | CNN

Editor’s Note: This is part of an ongoing series that takes a closer look at eating disorders, disordered eating and relationships with food and body image.



CNN
 — 

Ending cycles of dieting and learning to accept the body you are in sounds great, but it may feel a bit like a fairytale.

How can you control how you eat without counting calories? How should you stop planning for the day when you are thinner? How do you wake up one day without those shameful, mean thoughts knocking at the door to your brain?

It’s hard, said Bri Campos, a body image coach based in Paramus, New Jersey. The goal might not be fully celebrating your body or releasing yourself from all the negative thoughts about weight that comes from diet culture, she said. It could mean just making progress toward feeling less shame or self-criticism.

Diet culture is the widespread societal messages that small bodies are better, larger bodies are shameful and restricted eating is the key to an “acceptable” body. Ascribing to those messages is harmful to people of all body types, especially considering it can encourage eating disorders and make recovery therefrom even more difficult, according to the National Eating Disorder Association.

The promise of attaining (and retaining) the ideal body is hollow, as dropping weight drastically in a short period is likely to be followed by a person gaining it back again. Slow, sustained changes are often more successful, according to a 2017 study. And while some studies do recommend losing weight to reduce the risk of conditions such as heart disease and cancer, it’s also true that health is determined by many factors — shame doesn’t help.

There are ways to unlearn diet culture, Campos said. The process is different for each person, but it can help to find community with other people with similar goals, she added.

Here are several stories of people trying to reject diet culture and what they have found in their journeys along the way.

Shanea Pallone started to question her experience with diet culture after a doctor body-shamed her at an appointment. It’s been hard to be a patient in a medical system that has caused her great harm. “I am actively being harmed by providers who don’t see me as more than my weight on the scale,” Pallone said.

But Pallone, who lives in Houston, Texas, also works as a nurse; her job has required her to assess her patients’ weights, mark if they were considered obese on their medical charts and teach them the same dieting tactics she was trying to unlearn herself, she said.

Pallone recalled constantly asking herself, “How do I navigate my own care and giving good care and still work on unpacking some of the ways diet culture still sinks in?” Her answer included going back to research that showed that dieting wasn’t effective — and confirmed she could live healthfully and provide care without shame.

Learning about intuitive eating — an eating philosophy that relies on the body’s natural hunger and fullness cues — helped her in both her personal and professional journeys.

Changing her thinking doesn’t mean that intrusive thoughts about food and diet completely truly go away, but it has gotten easier to see them and try to quiet them, Pallone said. Now Pallone works to help her patients meet their health goals in a way that doesn’t keep them from the foods they love eating or make them feel like they’ve failed, she said.

But while she has been able to have some meaningful impacts on her patients, she had to accept she could not rescue everyone from diet culture.

“It is really hard to walk away from a woman in her 80s, who is moving toward hospice, who (is) like, ‘It’s really ok that I’m losing weight, I’ve always been a little chunky,’” Pallone said.

Amanda Mittman said the process of shedding diet culture is ongoing.

Amanda Mittman, a registered dietitian in Amherst, Massachusetts, began moving away from diet culture after her son was born. She couldn’t bring herself to return to a restrictive way of eating as a new mother, but still felt shame around the weight she hadn’t lost postpartum, she said.

“We’re all still swimming in the same toxic soup,” she said.

Mittman’s first step was to learn to identify diet culture around her, across entertainment media, in advertisements and even in conversations with friends and family, she said.

And once she saw it — like pulling the curtain back on the Wizard of Oz — she found she couldn’t go back to how she saw things before.

This didn’t mean she was ready to give up on dieting and completely accept her body. Diets had always offered her a magical solution: lose weight and you can have everything you’ve ever wanted. It was scary to give up on that dream — and to face the possibility that, in living differently, she might gain weight instead of losing it.

But as she found a community free of diet culture and moved her social media feeds to not value weight loss, Mittman said accepting the grief and mourning that comes with giving up on those goals became a big part of her process.

“I still have the thoughts of ‘wouldn’t it be great if I could lose weight?’” she said. But she reminds herself, “We have been down that road and that’s just not available to me anymore.”

The work to accept her body and love herself isn’t glamorous, she said. There’s “no cap and gowns, you don’t graduate — this is constant work,” Mittman said. “But it gets easier all the time.”

Sandra Thies' mirror was a big trigger and now is part of her healing.

After years on her college varsity rowing team and trying to shape her body to fit expectations, Sandra Thies found herself a little lost without a strict diet and exercise routine.

“The easy way out is to go on another diet, to buy into diet culture online, to restrict your eating,” Thies said. “It’s the easy way to feel that you have control.”

Much of that desire for control would come out around reflective surfaces, she said.

Whether it was the windows she walked by, mirrors in her work bathroom or even at home when she got out of the shower – all were places for Thies to poke and prod at her body, to see if she needed to work out or if she could give herself a little extra at dinner. And days wrestling with her reflection would lead to nights spent staring up at the ceiling, thinking about what she could do better the next day to get closer to her “ideal” body.

Thies, now an intuitive eating counselor in Kelowna, British Columbia, came across the concept in college and remembers thinking, “wouldn’t it be nice to be at peace with food and your body?” Four years later, she feels like she’s still learning how to move in a way that feels good, how to eat what her body needs and how to stand in front of her reflection without picking it apart.

But the mirror has actually become part of her solution, she said.

She has questions now written on her mirror at home: “What is the feeling? Where do you feel it in your body? How bad is it? Can we sit in this discomfort? What do you need in the moment?”

She now tries to take time to sit with those feelings. Sometimes, she can get through answering all the questions. But on the days she can’t, Thies said she gives herself permission to do what she can to keep her self-talk positive.

“I think about my body and food very frequently,” Thies said. “But the voice that I use has really changed. It leaves me feeling confident and empowered rather than broken down.”

Dani Bryant said she saw her own body in the women that came before her.

Dani Bryant thought her experiences with her body would threaten to her creative dreams, but instead they turned out to be an avenue to get there.

As a kid passionate about theater, Bryant heard similar messages from her directors, chorus teachers and costumers: You are so talented, but your body has to be smaller if you want to make it big.

She was only a 9-year-old when she first showed signs of disordered eating. By her sophomore year of college pursuing a career in theater, she had developed anorexia, Bryant said.

As part of Bryant’s recovery, she began writing and developed a theater company in Chicago centered around the experiences of body issues and disordered eating, Bryant said. There she found the support she felt was key to her developing relationship with her body.

“My healing is so much in sharing the lived experience, building community around it and that slow unlearning,” she said.

Bryant said finding a photo of her family coming to the US gave her better perspective on her own body.

One big moment in Bryant’s healing journey came when she went with her mother on a trip to Ellis Island in New York City, where they happened across a photograph of her family arriving in the United States generations ago.

In the photo, she saw her great grandmother, whose body was shaped just like her grandmother’s, her mother’s and her own, Bryant said.

There she realized her body was more than her choices or her dieting — it was the result of her family, genetics and her history.

She wished she could go back to the little girl she once was to show her that picture and ask her to stop fighting the “unwinnable war” for a smaller body she was never meant to have, she said.

11 minutes of daily exercise could have a positive impact on your health, large study shows | CNN

Sign up for CNN’s Fitness, But Better newsletter series. Our seven-part guide up will help you ease into a healthy routine, backed by experts.



CNN
 — 

When you can’t fit your entire workout into a busy day, do you think there’s no point in doing anything at all? You should rethink that mindset. Just 11 minutes of moderate-to-vigorous intensity aerobic activity per day could lower your risk of cancer, cardiovascular disease or premature death, a large new study has found.

Aerobic activities include walking, dancing, running, jogging, cycling and swimming. You can gauge the intensity level of an activity by your heart rate and how hard you’re breathing as you move. Generally, being able to talk but not sing during an activity would make it moderate intensity. Vigorous intensity is marked by the inability to carry on a conversation.

Higher levels of physical activity have been associated with lower rates of premature death and chronic disease, according to past research. But how the risk levels for these outcomes are affected by the amount of exercise someone gets has been more difficult to determine. To explore this impact, scientists largely from the University of Cambridge in the United Kingdom looked at data from 196 studies, amounting to more than 30 million adult participants who were followed for 10 years on average. The results of this latest study were published Tuesday in the British Journal of Sports Medicine.

The study mainly focused on participants who had done the minimum recommended amount of 150 minutes of exercise per week, or 22 minutes per day. Compared with inactive participants, adults who had done 150 minutes of moderate-to-vigorous aerobic physical activity per week had a 31% lower risk of dying from any cause, a 29% lower risk of dying from cardiovascular disease and a 15% lower risk of dying from cancer.

The same amount of exercise was linked with a 27% lower risk of developing cardiovascular disease and 12% lower risk when it came to cancer.

“This is a compelling systematic review of existing research,” said CNN Medical Analyst Dr. Leana Wen, an emergency physician and public health professor at George Washington University, who wasn’t involved in the research. “We already knew that there was a strong correlation between increased physical activity and reduced risk for cardiovascular disease, cancer and premature death. This research confirms it, and furthermore states that a smaller amount than the 150 minutes of recommended exercise a week can help.”

Even people who got just half the minimum recommended amount of physical activity benefited. Accumulating 75 minutes of moderate-intensity activity per week — about 11 minutes of activity per day — was associated with a 23% lower risk of early death. Getting active for 75 minutes on a weekly basis was also enough to reduce the risk of developing cardiovascular disease by 17% and cancer by 7%.

Beyond 150 minutes per week, any additional benefits were smaller.

“If you are someone who finds the idea of 150 minutes of moderate-intensity physical activity a week a bit daunting, then our findings should be good news,” said study author Dr. Soren Brage, group leader of the Physical Activity Epidemiology group in the Medical Research Council Epidemiology Unit at the University of Cambridge, in a news release. “This is also a good starting position — if you find that 75 minutes a week is manageable, then you could try stepping it up gradually to the full recommended amount.”

The authors’ findings affirm the World Health Organization’s position that doing some physical activity is better than doing none, even if you don’t get the recommended amounts of exercise.

“One in 10 premature deaths could have been prevented if everyone achieved even half the recommended level of physical activity,” the authors wrote in the study. Additionally, “10.9% and 5.2% of all incident cases of CVD (cardiovascular disease) and cancer would have been prevented.”

Important note: If you experience pain while exercising, stop immediately. Check with your doctor before beginning any new exercise program.

The authors didn’t have details on the specific types of physical activity the participants did. But some experts do have thoughts on how physical activity could reduce risk for chronic diseases and premature death.

“There are many potential mechanisms including the improvement and maintenance of body composition, insulin resistance and physical function because of a wide variety of favorable influences of aerobic activity,” said Haruki Momma, an associate professor of medicine and science in sports and exercise at Tohoku University in Japan. Momma wasn’t involved in the research.

Benefits could also include improvement to immune function, lung and heart health, inflammation levels, hypertension, cholesterol, and amount of body fat, said Eleanor Watts, a postdoctoral fellow in the division of cancer epidemiology and genetics at the National Cancer Institute. Watts wasn’t involved in the research.

“These translate into lower risk of getting chronic diseases,” said Peter Katzmarzyk, associate executive director for population and public health sciences at Pennington Biomedical Research Center in Baton Rouge, Louisiana. Katzmarzyk wasn’t involved in the research.

The fact that participants who did only half the minimum recommended amount of exercise still experienced benefits doesn’t mean people shouldn’t aim for more exercise, but rather that “perfect shouldn’t be the enemy of the good,” Wen said. “Some is better than none.”

To get up to 150 minutes of physical activity per week, find activities you enjoy, Wen said. “You are far more likely to engage in something you love doing than something you have to make yourself do.”

And when it comes to how you fit in your exercise, you can think outside the box.

“Moderate activity doesn’t have to involve what we normally think of (as) exercise, such as sports or running,” said study coauthor Leandro Garcia, a lecturer in the school of medicine, dentistry and biomedical sciences at Queen’s University Belfast, in a news release. “Sometimes, replacing some habits is all that is needed.

“For example, try to walk or cycle to your work or study place instead of using a car, or engage in active play with your kids or grand kids. Doing activities that you enjoy and that are easy to include in your weekly routine is an excellent way to become more active.”

High-quality bone broth comes ready-made. Here’s why you should make it yourself | CNN

Sign up for CNN’s Eat, But Better: Mediterranean Style. Our eight-part guide shows you a delicious expert-backed eating lifestyle that will boost your health for life.



CNN
 — 

After everyone at your table has devoured the juiciest pieces of a roast chicken and you’ve treated your canine to the edible rejects, hold off on sliding that picked-over carcass into the trash. Your bird has another gift for you: broth.

Making homemade broth requires only a few minutes of your time, and the benefits extend far beyond sensory pleasure: to your health, wealth, and even the world around you.

For centuries, humans have been simmering otherwise inedible animal parts in water, sometimes for days, extracting maximum flavor and nutrients from those bones for nourishing meals to come. Thrifty grandmas and chefs the world over have refined that technique, adding vegetables and seasonings reflecting their cultures and customs. Traditional recipes earned reputations for purported healing powers.

Over the last few decades, followers of the Paleo diet have incorporated 24-hour broth-making into their everyday kitchen routines, often sipping on their extra-strength broth as a gluten-free pick-me-up in place of coffee and tea — both of which are off-limits on their regimen.

New York City chef and Food Network personality Marco Canora turned to bone broth — which was regularly available to him at his popular restaurant, Hearth — to help him combat the effects of years of poor lifestyle habits. In 2014, he opened a takeout window called Brodo (Italian for broth) to sell to-go cups of his chef-crafted potions as beverages. He went on to write a book about it and sell it prepackaged and frozen nationwide.

Breathless testimonies from celebrity influencers of bone broth’s purported magical powers — from easing joint pain to reducing wrinkles to improving gut health — flooded the internet. Products labeled “bone broth” popped up on supermarket shelves. The trend shows no sign of abating. When last checked, TikTok videos with the hashtag #bonebroth had received more than 158 million views.

Some dietitians and medical professionals agree that bone broth can be a worthy addition to a balanced diet — supplying collagen and other important nutrients. But given that every bone broth recipe and human body are different, specific health claims linked to bone broth should be taken with a grain of salt.

I had been skeptical of the hype all along, and uninterested in exploring it for myself, until I made a batch last fall by accident while cleaning up after Thanksgiving dinner. Unable to find room in the fridge for the half-eaten turkey, I sawed off the remaining sandwich-worthy slices and dumped the picked-off carcass and grisly parts into my slow cooker, along with half an onion and a few odds and ends from the crisper.

I set the cooker to low and left it alone for a full 24 hours, giving me time to recuperate from the previous festivities while basking in the tantalizing fragrances wafting from the kitchen.

The first taste of the finished broth blew me away — richer and more complex than any packaged product or broth I’d made from scratch on top of my stove in a fraction of the time. I could practically feel the nourishment coursing through my bones. I placed the strained broth in the fridge and was happy to find it congealed to a jiggly consistency the next day, a clear sign that those picked-off turkey parts had done their job. And now I had the foundation for restaurant-quality gumbo made almost entirely with remains of the feast: a win-win all the way around.

My curiosity was piqued. So what if bone broth wasn’t the cure-all it was cracked up to be. It was wholesome, grocery-stretching and most importantly to me, freaking delicious. I wanted to figure out how to reap the full spectrum of advantages bone broth had to offer. I turned to experts for guidance.

Linton Hopkins, a James Beard Award-winning chef who helms the newly reopened Holeman & Finch Public House in Atlanta along with other high-profile spots in the South, learned the craft the classic way at the Culinary Institute of America.

“As a chef and a cook, I don’t feel good without a stock going. It’s one of my things,” Hopkins said. “We make all our stocks at our restaurants. And I do it all the time at home for me and my wife, Gina. They’re the easiest thing in the world. I’ll roast a whole chicken, we’ll eat what we can, and the rest will go right into the Instant Pot. I did the same thing with the bones from a beef roast last night. I’m no doctor, but I know good food is good for your life.”

Besides taste and nutrition, broth-making  can be a sound economic decision for the budget-conscious.

The terms “stock” and “broth” are often used interchangeably, Hopkins noted. But stocks typically indicate a higher bone-to-meat ratio. Broths can even be made with just the meat. “But as a whole-animal, whole-vegetable cook, all my stocks and broths are essentially bone broth. I see stock as an ingredient I cook with. Broth to me is a finished word — meaning it’s ready to serve in a bowl as is.”

Aside from taste and nutrition, he views stock- and broth-making as both an economic decision and an ethical responsibility.

“In the restaurant business, the margins are very thin, so we have to strive for zero waste,” he said. “We ask a lot of an animal to give its life for our diets. If we’re going to bring these items into our kitchens and throw them away after a single use, then we’re part of the problem.”

Michelle Tam grew up in a traditional Cantonese American household in California’s Bay Area where her mother served multicourse meals that always ended with soup.

“And she would always throw a bone in there. I remember as a kid we would walk down to the neighborhood butcher, and he would step out of the freezer with this giant plastic bag of bones for 25 cents,” Tam said. “We would get a variety of different kinds of bones with some meat left on them that would flavor the soup, and it was really delicious.”

But it wasn’t until she and her husband began eliminating processed foods from their diets and replacing them with wholesome ones as part of a fitness regimen that she considered making broth from scratch herself. “I don’t know that it’s some magical elixir,” said Tam, a former clinical pharmacist who now creates recipes full time for her popular Nom Nom Paleo blog and spin-off cookbooks. “But it’s a great source of collagen, which most people don’t get enough of and is really important for joints and gut health and all that stuff.”

Chicken feet can be among the tasty bone broth ingredients, providing a great source of collagen.

Collagen is the main constituent of connective tissue fibrils and bones that releases gelatin into liquid as it cooks. It’s most abundant in skin, feet, joints, marrow and knuckles. Tam may mix parts from different animals — lamb, pork, beef, chicken. The results, she said, are inevitably tasty.

“I’m always collecting chicken thigh bones, and I buy chicken feet when I see them at the butcher,” she said. Chicken feet contain tons of collagen, she said. But she warned not to go overboard, or you may wind up with a rubber ball. “I tried that, and it wasn’t delicious. One or two should do the trick. I also like to include something meaty for flavor, like a chicken leg. And chicken wings are excellent.”

Because bone broth can be “a spectacular growth medium for bacteria,” Tam refrigerates hers as soon as it reaches room temperature, and whatever isn’t consumed within a few days goes into the freezer. She offers ways to store bone broth conveniently and safely in usable portion sizes (she’s tried muffin tins, ice cube trays and silicone baking molds) and recipes for her favorite ways of using broth in a super-simple egg drop soup and slow cooker Korean short ribs on her blog.

With her multi-cooker, Tam can now produce collagen-rich bone broth in as little as an hour. But she’s not above buying bone broth ready-made when time is short or personal bone supplies are low, now that she’s found several brands she can trust. Roli Roti, which began as a food truck in the Bay Area selling rotisserie chicken, contains only a couple of ingredients and is “super high quality and super gelatinous.” Bonafide Provisions, found in many supermarket freezer sections, has become another standby.

Cassy Joy Garcia, a certified holistic nutritionist and New York Times best-selling cookbook author, became a fan of bone broth more than a decade ago during her marathon-running days and writes about it regularly on her healthy lifestyle blog, Fed + Fit.

“I think bone broth is getting some new attention now with grocery prices on the rise and people wanting to do more with less,” Garcia said. “I feel like it’s an easy entry point for some good DIY kitchen basics. If you’ve already roasted a chicken, just go ahead and throw that carcass in your pot or pressure cooker along with that random onion in the pantry and scraggly carrot in the fridge, and lo and behold, you’re going to save yourself some money and have broth that tastes better and is better for you than anything you’d buy.”

Toss in vegetable scraps from your fridge such as carrots and celery when preparing a bone broth.

She collects leftover bones from roasted meats and chicken in silicone freezer bags and keeps a veggie bowl at the forefront of her fridge for tossing in vegetable scraps, peels and all that could go into a homemade broth.

Now with more mouths to feed as a mother of three preschoolers, she does allow herself to take a shortcut from time to time with a quality premade product. One of her favorites is Fond sipping broth made of grass-fed beef and pasture-raised chicken bones, which come in flavor combinations such as ginger and cayenne, and shiitake and sage.

“They’re definitely a luxury product,” she said. “But they’re really a cool way to show what a broth can be and can open our eyes to exploring different flavors we can play with at home.”

On her blog, Garcia offers a detailed guide to making beef and chicken bone broth, and a slightly more complex one boosted with turmeric and ginger, which she uses for making her favorite chicken soup.

She gives you the options for making the broth in various vessels but makes no bones about her preference for her high-speed pressure cooker.

As for myself, I’m sticking to my slow cooker for now, content to inhale those 24-hour aromatics all day and allow them to soothe me to sleep.

Since Thanksgiving, I’ve made several more batches of bone broth following advice from the experts and falling down many rabbit holes of online research along the way.

I’ve been patronizing the nearby international farmers market more often to seek out a variety of bones from animals that have been responsibly raised without harmful chemicals that could negate my broth’s potential health benefits.

Freeze whatever hasn't been consumed of your bone broth within a few days of making it.

Some purists only use bones and water, giving them more flexibility to add layers of flavor later. But I can’t resist throwing in a few extras to amp up the nutritional and flavor profile (roasted mushrooms and a splash of red wine for beef, fresh ginger and turmeric for chicken, and always extra cloves of garlic).

I’ve made a habit of stashing yogurt containers of my finished products, along with baggies of leftover bones and trimmings, so long as space permits in my freezer.

Serious chefs boil the bones first to rid them of some of the impurities and then caramelize them in a 400- to 450-degree oven to deepen their flavors before proceeding. One day maybe I’ll find the motivation to give that a try.

I have quickly learned that, as easy and satisfying as bone broth is to make, I’m lucky if I can produce 2 quarts at a time — barely enough for one batch of soup or gumbo. But I wasn’t planning to replace my morning coffee with steaming broth anyway. And if I’m really hankering for the real deal before I get around to making another batch, I’m happy to have discovered I can buy Roli Roti, the brand Tam recommended, in the meat department of my neighborhood Publix.

You don’t have to follow any recipe to make bone broth. But it does help to have some guidance until you get the hang of it. Here’s the basic formula I’ve been loosely going by based on several recipes I’ve studied. Feel free to deviate with what the local butcher needs to dispense of, or what’s soon to go south in your fridge. Mother Earth will be grateful.

Susan Puckett’s recipe for bone broth is highly flexible. If you have no leftover bones, chicken or turkey wings, drumsticks, necks and gizzards also work great. For extra collagen, a few chicken feet will do the trick. For beef broth, follow the same procedure as for chicken. Or feel free to use bones from other animals as well — lamb, pork, game. Larger bones will take longer to break down so you may want to allow more simmering time.

Makes roughly 2 quarts (or more, if you have a larger vessel)

2-3 pounds roasted or raw chicken or beef bones, or a combination

2 carrots, cut up

2 celery stalks, cut up

1 medium unpeeled onion, halved

5 unpeeled garlic cloves, smashed

2 bay leaves

1 teaspoon salt

1 teaspoon peppercorns

2 tablespoons cider vinegar

Water

1. Place the bones, carrots, celery, onion, garlic, bay leaves, salt, peppercorns and vinegar in a slow cooker (mine holds 6 quarts) and add enough water so bones are submerged but not floating.

2. Cover with the lid and let simmer on low setting for 12 to 24 hours.

3. Skim off any scum that’s collected on the surface. Turn off the heat and let it cool slightly. Discard the solids (picking out edible meat bits for yourself or the dog.)

4. Set a large fine-mesh sieve over a large bowl, strain and let it cool to room temperature. Cover and refrigerate. Scrape off the fat that congeals on the surface.

5. Use within four to five days or transfer to jars or plastic containers, label and freeze for up to five months. (Or pour the broth into ice cube trays, muffin tins or silicone molds, and freeze and pop them out into freezer bags.)

What’s the magic number of steps to keep weight off? Here’s what we know | CNN

Taking 8,600 steps a day will prevent weight gain in adults, while already overweight adults can halve their odds of becoming obese by adding an additional 2,400 steps — that’s 11,000 steps a day, according to an October 2022 study.

Studies show the average person gains between 1 and 2 pounds (0.5 to 1 kilograms) each year from young adulthood through middle age, slowly leading to an unhealthy weight and even obesity over time.

“People really can reduce their risk of obesity by walking more,” said study author Dr. Evan Brittain, associate professor in the division of cardiovascular medicine at Vanderbilt University Medical Center in Nashville.

The study also found key benefits for chronic diseases and conditions: “Diabetes, sleep apnea, hypertension, diabetes, depression, and GERD showed benefit with higher steps,” said Brittain via email.

“The relationship with hypertension and diabetes plateaued after about 8,000 to 9,000 steps but the others were linear, meaning higher steps continued to reduce risk,” he said. “I would say that the take home messages are that more steps are better.”

It’s yet another study illustrating the powerful impact that walking and other forms of exercise have on our health. In fact, if you get up and move for 21.43 minutes each day of the week, you cut your risk of dying from all causes by one-third, according to the US Centers for Disease Control and Prevention.

Current physical activity recommendations for adults are 150 minutes of moderate-intensity exercise, such as brisk walking, dancing, bicycling, doubles tennis and water aerobics, and two days of muscle-strengthening activity each week.

“Physical activity is just absolutely magnificent,” Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver, told CNN in an earlier interview.

“And when if you blend that with eating a more plant-based diet, de-stressing, sleeping enough and connecting with others — that’s your magic recipe,” Freeman said. “It’s the fountain of youth, if you will.”

Activity trackers allow researchers to get more accurate data that can be compared with health records.

The study analyzed an average of four years of activity and health data from more than 6,000 participants in the National Institutes of Health’s All of Us Research Program, dedicated to research on ways to develop individualized health care.

Participants in the study, published on October 10, 2022, in the journal Nature Medicine, wore activity trackers at least 10 hours a day and allowed researchers access to their electronic health records over multiple years.

“Our study had an average of 4 years of continuous activity monitoring. So, we were able to account for the totality of activity between when monitoring started and when a disease was diagnosed, which is a major advantage because we didn’t have to make assumptions about activity over time, unlike all prior studies,” Brittain said.

People in the study ranged in age from 41 to 67 and had body mass index levels from 24.3, which is considered in the healthy weight range, to 32.9, which is considered obese.

Researchers found that people who walked 4 miles a day — about 8,200 steps — were less likely to become obese or suffer from sleep apnea, acid reflux and major depressive disorder. Sleep apnea and acid reflux respond well to weight loss, which can reduce pressure on the throat and stomach, while exercise is a cornerstone treatment for depression.

The study also found that overweight participants (those with BMIs ranging from 25 to 29) cut their risk of becoming obese by half if they increased their steps to 11,000 steps a day. In fact, “this increase in step counts resulted in a 50% reduction in cumulative incidence of obesity at 5 years,” the study found.

Applying the data to a specific example, the authors said individuals with BMIs of 28 could lower their risk of obesity 64% by increasing steps from about 6,000 to 11,000 steps per day.

This research echoes results from a recent study in Spain in which researchers found health benefits rose with every step until about 10,000 steps, when the effects began to fade. Counting steps may be especially important for people who do unstructured, unplanned physical activity such as housework, gardening and walking dogs.

“Notably, we detected an association between incidental steps (steps taken to go about daily life) and a lower risk of both cancer and heart disease,” study coauthor Borja del Pozo Cruz told CNN in an earlier interview. Del Pozo Cruz is an adjunct associate professor at the University of Southern Denmark in Odense and senior researcher in health sciences for the University of Cadiz in Spain.

The same research team also published a similar study in September 2022 that found walking 10,000 steps a day lowered the risk for dementia by 50%; the risk decreased by 25% with as few as 3,800 steps a day.

However, if walking occurred at a brisk pace of 112 steps a minute for 30 minutes, it maximized risk reduction, leading to a 62% reduction in dementia risk. The 30 minutes of fast-paced walking didn’t have to occur all at once either — it could be spread out over the day.

Researchers found the association between peak 30-minute steps and risk reduction to be dependent on the disease studied: There was a 62% reduction for dementia, an 80% decline for cardiovascular disease and death, and about a 20% drop in risk for cancer.

The study also found an association between step intensity and health benefits as well, “although the relationships were less consistent than with step counts,” researchers said.

A major limitation of all studies using step trackers is that people who wear them tend to be more active and healthier than the norm, the researchers said. “Yet the fact that we were able to detect robust associations between steps and incident disease in this active sample suggests even stronger associations may exist in a more sedentary population,” they said.

Restrict calories to live longer, study says, but critics say more proof is needed | CNN



CNN
 — 

People of normal weight may be able to extend their life span by restricting calories, according to a new study that attempted to measure the pace of aging in people asked to cut their calorie intake by 25% over two years.

“We’ve known for nearly 100 years that calorie restriction can extend healthy life span in a variety of laboratory animals,” said senior author Daniel Belsky, an associate professor of epidemiology at Columbia University Mailman School of Public Health.

“It does this by changing biology in ways consistent with a slowing of the process of aging, although the specific mechanisms of how this occurs are still under investigation,” said Belsky, who studies longevity. “We decided to drill down to the cellular level in people to see if the same is true.”

The study used what are commonly known as “biological clocks” to determine the pace of aging in its participants. Bioclocks are designed to measure how old people are biologically compared with their real ages chronologically.

“Our study found evidence that calorie restriction slowed the pace of aging in humans,” said colead author Calen Ryan, an associate research scientist at the Robert N. Butler Columbia Aging Center at Columbia.

“Our findings are important because they provide evidence from a randomized trial that slowing human aging may be possible,” Ryan said in a statement.

But longevity scientist Dr. Peter Attia dismissed the study results as “noise.”

“I just don’t see any evidence that any of the biologic clocks have meaning,” Attia, who was not involved in the study, said via email. He hosts “The Drive,” a podcast dedicated to explaining and applying longevity research to everyday life.

“The only validation that matters — which to my knowledge has not been done, but hopefully will be — is to see if ‘biologic age’ can predict future life better than chronological age,” he said.

Biological age predictors are controversial, said calorie restriction researcher Pankaj Kapahi, a professor at the Buck Institute for Research on Aging in Novato, California.

“At best, they’re telling you something about a very small aspect of aging,” said Kapahi, who was not involved in the study. “For example, grip strength is also a biological age predictor, how active you are is a predictor, and we all know people who fall apart physically but are cognitively all there, so you also need to test cognitive aging.

“Some researchers are trying to boil it down with bio-aging tests,” he added. “This is a much more complex problem, and I think it’s an overstatement to say the tests really predict biological age.”

Decades of research in animals have shown that calorie restriction produces health benefits, even slowing the pace of aging. Would the same be true in people?

A study in the 1950s asked people to reduce 50% of their calories, leading to malnutrition or a lack of key micronutrients in participants. Later research often focused on calorie reduction in people whose body mass index would be considered medically obese.

The first clinical trial of calorie restriction in people at normal weight (a BMI of about 20 to 25) started in 2007. It was called CALERIE, or the Comprehensive Assessment of Long-Term Effects of Reducing Intake of Energy.

Because of the malnutrition found in the earlier study that cut calories drastically, CALERIE asked 143 adults between the ages of 21 and 50 to cut 25% of the calories they typically ate for a two-year period. Another group of 75 people maintained their normal diets, serving as a control group.

During the trial, all manner of tests were done at six-month intervals to gather information on weight loss, change in resting metabolic rate, impact on cognitive function and markers of inflammation, cardiovascular health and insulin sensitivity.

The results of CALERIE, published in 2015, found that on average people in the restricted group were able to cut 14% of their calories, or about half of the 25% goal. However, that amount reduced their fat mass by about 10% and decreased their cardiometabolic risk factors with no adverse effects on quality of life, researchers said. There were also reductions in tumor necrosis factor alpha, a protein that promotes insulin resistance and obesity-induced type 2 diabetes.

A number of other studies have used blood samples and other data collected on the CALERIE participants to explore other ways modest calorie restriction might benefit the body. For example, Yale University researchers found restricting calories increased the health of the thymus, an organ that produces immune system T cells — one of the body’s key warriors against invaders.

The new study, published Thursday in the journal Nature Aging, culled DNA sequences from white blood cells taken at 12-month intervals from participants in CALERIE. Belsky’s team then analyzed methylation marks — signs of epigenetic changes — on the DNA, looking for symptoms of aging.

Epigenes are proteins and chemicals that sit like freckles on each gene, waiting to tell the gene “what to do, where to do it, and when to do it,” according to the National Human Genome Research Institute.

“Increasingly, changes to our cells’ epigenomes, the systems that control which genes in the genome are turned on and off, are being recognized as drivers of the aging process,” said anti-aging expert David Sinclair, a professor of genetics in the Blavatnik Institute at Harvard Medical School and codirector of the Paul F. Glenn Center for Biology of Aging Research.

“Clocks that measure these changes are proving to be indicators of future health and what interventions might slow and even reverse the aging process,” said Sinclair, who was not involved in the study.

In the new study, researchers used two epigenetic clocks — PhenoAge and GrimAge — and a new tool Belsky recently invented in conjunction with Duke University. This third bioclock, called DunedinPACE, attempts to determine the pace of aging from a single blood test, Belsky said.

The PhenoAge and GrimAge bioclocks showed no signs of reduced aging in the blood samples of participants in CALERIE, said Belsky, who is also a scientist with Columbia’s Robert N. Butler Aging Center.

However, DunedinPACE, the clock created by Belsky’s and Duke’s teams, did find a 2% to 3% reduction in the pace of aging, “which in other studies translates to a 10-15 percent reduction in mortality risk, an effect similar to a smoking cessation intervention,” according to a statement from Columbia.

Critics of the study, however, were not impressed. The performance of the DunedinPACE test was “mediocre at best,” Attia said, finding only a weak association with biological aging.

The fact that the two other bioclocks found no anti-aging benefits was no surprise, said the Buck Institute’s Kapahi: “These biological age predictors don’t agree with each other and don’t necessarily agree with other biological measures.

“It’s going to confuse the public, and unfortunately people are buying these tests when there’s very little useful information that comes out of them.”

While it’s true epigenetic biomarkers are not yet ready to be used in clinical trials, “many different studies in many different datasets and populations have shown these algorithms are predictive of differences between people in who gets sick and who lives or dies,” Belsky countered.

“This is not a game over moment. It’s more like game on,” Belsky said. “What we have now is a proof of concept — a methylation biomarker that shows faster aging in people we know to be at higher risk for disease, disability and death, and slower aging in people who we know to be at lower risk.”

Putting aside the debate over how slower aging is measured, there is a role for caloric restriction in extending life, especially in “overnourished” individuals, Attia said.

“I don’t want a reader to think this intervention (calorie restriction) is of no value, only that (the study) does not ‘prove’ a reduction in the pace of aging,” he said in an email.

Time-restricted eating and dietary restriction of certain foods are two additional ways to curb “overnutrition,” which Attia believes is the biggest driver of insulin resistance, type 2 diabetes and other chronic diseases.

“I am not aware of any evidence that one ‘strategy’ or method is superior. The best one is the one that works for a person, but calorie restriction certainly works for some, and therefore is clearly beneficial,” Attia said. “All of these interventions will lead to a longer and better life, but these aging clocks tell us less than zero about that process.”

There are many other ways to curb aging as well, Kapahi said.

“We’re trying to learn more about aging and we are, but calorie restriction is just one intervention,” he said. “You likely need to do that in combination with exercise, with good sleep, with a positive attitude and good mental health. All these things combined will likely play a much bigger role in slowing aging.”
