People with health conditions like type 2 diabetes, gestational diabetes or polycystic ovarian syndrome may have been advised about the value of an insulin-resistance diet. But this way of eating can benefit most people interested in balancing blood sugars, whether that’s to help treat or prevent chronic conditions, or just to gain more energy and better mood control. “An ‘insulin-resistant diet’ is a diet or eating plan that supports balanced blood sugars in the body,” explained Rahaf Al Bochi, a registered dietitian and owner of Olive Tree Nutrition in Duluth, Ga. Insulin is a hormone produced by the pancreas that helps sugar (glucose) from the bloodstream enter into cells, explained Al Bochi, who is also a spokeswoman for the Academy of Nutrition and Dietetics. “When cells don’t respond to insulin anymore, they are ‘insulin resistant’ and blood sugars can rise,” she said. The American Diabetes Association (ADA) explains it this way: Some people build up a tolerance to insulin, requiring more to get muscle, fat and liver cells to take up glucose. It can be chronic or temporary, according to the Cleveland Clinic. Why this develops is not clear, but reasons can include genes, age, inflammation, other physiological stress and some medications. Lifestyle, too, such as being inactive or overweight can play a role. A recent study of hibernating bears may eventually improve understanding about… read on > read on >

Americans who live near a “food swamp” may have a higher risk of suffering a stroke, a preliminary study finds. A number of studies have looked at the health consequences of living in a so-called food desert — areas with few grocery stores or other options for buying fresh food. Food swamps are different: The term was coined to describe communities where fast food restaurants, convenience stores and other junk-food purveyors heavily outweigh healthier options like grocery stores and farmers’ markets. The new study looked at whether Americans’ stroke risk varies based on how far their county of residence veers into food swamp territory. It turned out it did: Among nearly 18,000 adults age 50 and older, those living in U.S. counties high on the food swamp scale had a 13% higher risk of suffering a stroke, compared to those in areas with more healthy options. Many factors affect stroke risk, and it is hard to separate the importance of food swamps from those other variables, said lead researcher Dr. Dixon Yang, a postdoctoral fellow at Columbia University Irving Medical Center in New York City. In fact, he said, the food swamp issue is intertwined with other factors in those communities. People living there may have lower incomes, little time or places for exercise, or less access to health care, for example. But food swamps… read on > read on >

Fizzy sodas, microwaveable meals and packaged cookies are convenient for people on the go, but these folks might not go as far as they’d like if that’s all they eat. Ultra-processed foods appear to increase the risk of developing and dying from a variety of cancers, a new large-scale study says. Every 10% increase of these foods in your diet increases your overall risk of cancer by 2% and your risk of a cancer-related death by 6%, researchers reported Jan. 31 in eClinical Medicine. The risk is even higher for specific cancers, particularly those that primarily affect women. For example, every 10% increase in a woman’s consumption of ultra-processed foods makes her 19% more likely to develop and 30% more likely to die from ovarian cancer, the investigators found. The researchers describe ultra-processed foods as “industrial formulations made by assembling industrially derived food substances and food additives through a sequence of extensive industrial processes.” Industrially derived ingredients include things like high-glucose corn syrup, modified starch, protein isolates, emulsifiers, stabilizers and preservatives, the study authors said. “Our bodies may not react the same way to these ultra-processed ingredients and additives as they do to fresh and nutritious minimally processed foods,” lead researcher Kiara Chang, a research fellow with Imperial College London’s School of Public Health, said in a college news release. “However, ultra-processed foods are everywhere… read on > read on >

Dave Conway had a heart attack in 2018. He was only 30. The Clintonville, Ohio, resident had been experiencing fatigue and shortness of breath, finally going to the emergency room with what he thought was pneumonia. Instead, he learned he’d had a “widowmaker” heart attack and a 100% blockage in a major artery. “I thought people who had heart attacks or heart disease were older people who drink and smoke a lot and weigh much more than I did,” Conway said. “Recovery has been really tough, but I’m willing to do whatever my doctors tell me is needed to keep my heart safe in the future,” he said in an Ohio State University news release. Stories like Conway’s are becoming more common, with studies showing heart attacks and stroke are on the rise among Americans younger than 40. Certain healthy habits can help prevent heart problems — but getting younger adults to accept their risks remains an obstacle. “It is alarming that younger people don’t feel that they’re at risk for heart disease, but it’s not surprising,” said Dr. Laxmi Mehta, director of preventative cardiology and women’s cardiovascular health at the Ohio State Wexner Medical Center. “Most young people think heart disease only happens in old people, but that’s not the case,” Mehta said in the release. The medical center surveyed 2,000 Americans, finding that… read on > read on >

Stung by recent food safety scandals — most notably last year’s infant formula shortage, the U.S. Food and Drug Administration announced Tuesday that it is creating a new unit devoted to food safety. The newly dubbed Human Foods Program will wield wide-ranging powers. “We’re proposing the creation of a unified, newly envisioned organization, called the Human Foods Program, that elevates key focus areas, removes redundancies and consolidates activities under a single leader, a deputy commissioner for human foods,” FDA Commissioner Dr. Robert Califf said during a media briefing announcing the change. The deputy commissioner “will have clear decision-making authority and oversight of priorities to ensure a safe and nutritious U.S. food supply,” Califf added. Not only that, the new program will “elevate the importance of nutrition, given declining life expectancy in the U.S. due in large part to chronic diseases with a basis in nutrition,” he noted. The sweeping move comes after a scathing report in early December from the Reagan-Udall Foundation found that the FDA’s food program is in a state of “constant turmoil” and requires stronger leadership. That report was commissioned by Califf once the agency conducted its own review after facing serious criticism for its handling of the infant formula shortage. That shortage, which dragged on for months, was prompted in part by a recall of potentially contaminated infant formula at Abbott… read on > read on >

People with celiac disease may be more likely to develop heart disease despite having fewer traditional heart risks than other folks. Celiac disease is an immune reaction that occurs when some people eat gluten, a protein found in wheat, barley and rye. The only treatment is following a strict gluten-free diet. People with celiac disease may be 27% more likely to develop heart disease compared with those without this autoimmune condition, and the longer a person has celiac disease, the higher the risk, a new study suggests. “People with celiac disease have an increased risk of heart disease that is independent of traditional risk factors, such as high blood pressure and cholesterol levels,” said study author Megan Conroy, an epidemiologist at the University of Oxford in the United Kingdom. The new study wasn’t designed to say how, or even if, celiac disease raises the risk for heart attack and stroke, but researchers do have some theories. “The increased risk could be due to inflammation in those with celiac disease as is seen in people with other autoimmune diseases, or it is linked in some way to consuming a gluten-free diet; however, without further research, we cannot say,” Conroy said. Until more is known about this link, people with celiac disease should follow recommendations for a healthy heart and see their doctor if they have any… read on > read on >

Longstanding restrictions on blood donations from gay or bisexual men could soon shift towards a more nuanced policy, where such men are asked about sexual partners and practices instead, the U.S. Food and Drug Administration announced Friday. Specifically, gay men who are in monogamous relationships will no longer be required to abstain from sex for any period of time before donating to the nation’s blood supply. Old rules in place since the 1980s had made such demands, out of fears of possible HIV contamination of donated blood. But pressure from LGBT organizations, improvements in blood screening technologies, as well as the input of blood banks and the American Medical Association, have all pushed the FDA to re-examine its rules. The draft recommendations around the new policy center on “individual risk-based questions to reduce the risk of transfusion-transmitted HIV,” the agency explained in a statement. “These draft recommendations are based on the FDA’s careful review of available information, including data from other countries [such as Canada and the United Kingdom] with similar HIV epidemiology that have instituted this approach, as well as ongoing surveillance of the U.S. blood supply,” the agency added. “Maintaining a safe and adequate supply of blood and blood products in the U.S. is paramount for the FDA, and this proposal for an individual risk assessment, regardless of gender or sexual orientation, will… read on > read on >

The U.S. Food and Drug Administration said Thursday it can’t regulate CBD supplements because there isn’t enough evidence on their safety. The agency also called on Congress to create new rules for what has become a burgeoning industry. “The use of CBD raises various safety concerns, especially with long-term use,” FDA Deputy Commissioner Dr. Janet Woodcock said in a statement. “Studies have shown the potential for harm to the liver, interactions with certain medications and possible harm to the male reproductive system. CBD exposure is also concerning when it comes to certain vulnerable populations such as children and those who are pregnant.” “The FDA’s existing foods and dietary supplement authorities provide only limited tools for managing many of the risks associated with CBD products,” Woodcock added. “Given the available evidence, it is not apparent how CBD products could meet safety standards for dietary supplements or food additives.” “For example, we have not found adequate evidence to determine how much CBD can be consumed, and for how long, before causing harm,” Woodcock noted. “Therefore, we do not intend to pursue rule-making allowing the use of CBD in dietary supplements or conventional foods.” Meanwhile, the FDA has warned some companies about making health claims for the ingredient, which the agency said it plans to continue doing. How to regulate CBD supplements has become a pressing public health… read on > read on >

The U.S. Food and Drug Administration’s vaccine advisory panel on Thursday voted unanimously to recommend that the agency phase out original versions of COVID vaccines for use in the unvaccinated, in favor of updated bivalent booster shots. Committee members also weighed a proposal to streamline the dosing schedule for COVID vaccines by turning them into annual shots that would likely be given every fall. However, the committee did not vote on the proposal because many questions remain and more data on exactly who should get those annual shots, and exactly when, is sorely needed. Still, they agreed that COVID vaccines do need to become more routine, to clear up public confusion and hopefully boost vaccination rates. Such a move would be critical, given the fact that efforts to get people to get the updated COVID booster shots have fallen far short of expectations. While over 80% of Americans have had at least one dose of the original COVID-19 vaccine, only 16% of those over the age of 5 have gotten the updated booster shots that were approved last August, according to the U.S. Centers for Disease Control and Prevention. “We can’t keep doing what we are doing,” said panel member Dr. Bruce Gellin, chief of global public health strategy at the Rockefeller Foundation. “This is a good path forward.” But some committee members said it… read on > read on >

Just like adults, children need lots of fiber in their diets. Fiber is part of what fuels a child’s normal growth and development. It helps them feel full longer, controls blood sugar levels, reduces cholesterol and promotes regular bowel movements, according to Children’s Health of Orange County, Calif. (CHOC). “We see improvements in disease management like diabetes with lower spikes in blood sugar after meals when fiber intake is adequate. Improved satisfaction and satiety from the food we are consuming is evident when they contain more fiber, and this ultimately impacts weight management,” said Stephanie Di Figlia-Peck, nutrition coordinator at Cohen Children’s Medical Center in New York City. A child who is still hungry will continue to eat, she said, so “a filling, satisfying, higher fiber meal will end the eating episode sooner.” However, most American children aren’t getting enough fiber in their diet. A recent study in the journal BMC Pediatrics found that few young children were getting the recommended amount of fiber in their diet. Those who got more fiber tended to eat more whole grains, fruits, vegetables, nut butter and legumes, along with fewer fats. “Fiber tends to be the misunderstood, scarcely present dietary constituent that eludes many. This is especially true for today’s youth who eat more processed, and ultra-processed, foods than generations of the past,” Di Figlia-Peck noted. Foods are… read on > read on >
