Research increasingly demonstrates that healthy nutrition improves mental health, and an entirely new subspecialty has formed to support this. Nutritional psychiatry is expanding rapidly, with research growing 15-fold from 2000 to 2024, reflecting the increasing acceptance of diet's role in mental health.
These tiny packages pack a nutritional punch-so much so that the advisory committee for the 2025 U.S. Dietary Guidelines recommended upping the daily serving size of legumes and promoting them as a protein source over meat and seafood. Navy beans, for example, are especially fiber-dense, and lentils are protein powerhouses.
Compared with a control group that also reduced calories but did not eat oats, those on the oat based plan saw a markedly greater improvement in their cholesterol levels. The reduction remained noticeable even six weeks later. Researchers also found that the diet changed the balance of bacteria in the gut. Substances produced by these microbes appear to play an important role in the health benefits linked to oats.
The article from the journal argues that the gut-autism axis is a house of cards built on lousy studies with inconsistent data. They assert that the studies are contradictory and that too much emphasis is placed on dubious mouse models. It is notoriously challenging to nail down microbial causes of disease—it is hard enough to simply identify a normal microbiome.
Fiber comes in two forms - soluble and insoluble. The former helps to regulate blood sugar levels in in the body, while the latter promotes healthy digestion by keeping food moving through the gut. Many fruits contain both types of fiber, so incorporating them into your snacks, breakfast bowls, and desserts comes with significant benefits.
This study is really good news for those who follow a vegetarian diet because they have a lower risk of five cancer types, some of which are very prevalent in the population. While being vegetarian appeared to be protective overall, the scientists also found that those who follow a vegetarian diet had nearly double the risk of the most common type of cancer of the oesophagus, known as squamous cell carcinoma, compared with meat eaters.
I grew up in a Mexican household where food was our love language - but there was also stigma and very little guidance around diabetes. When my aunt, and later my mom, were diagnosed, it took time to understand what healthy eating could look like for them. That's why this partnership means so much to me. Our culture and our food are not the problem - they're part of the solution.
Most of the carbohydrates in these foods - as well as most of the calories - come from starch, of which there are two types: hard-to-digest amylose and easily digested amylopectin. The latter is processed quickly and spikes blood sugar. The former is processed slowly and moderates blood sugar.
There are some communities that are very unhealthy where the diversity is higher. Low diversity is not a universal marker. We found something that at first seemed surprising. That a healthy microbiome has lots of competition. These bugs are all going after the same food. In an unhealthy gut, on the other hand, you see tight cooperation - microorganisms are helping each other out.
Barley, the grain that is featured in this dish, is one of our most nutritious grains; it contributes protein, thiamine and niacin. Barley also is a rich source of dietary fiber. For a vegan rendition, use vegan yogurt and maple syrup instead of honey in the dressing and use olive oil instead of butter when sauteing the mushrooms. The dish is a main course salad and should be served at room temperature.
Sorbitol can be metabolized into fructose in the liver, directly linking its consumption to the same harmful pathways that cause fatty liver disease and metabolic dysfunction. This discovery forces a sobering reevaluation of the artificial and alternative sweeteners millions consume daily in an effort to live healthier lives.
The Dietary Guidelines for Americans aim to translate the most up-to-date nutrition science into practical advice for the public as well as to guide federal policy for programs such as school lunches. But the newest version of the guidelines, released on Jan. 7, 2026, seems to be spurring more confusion than clarity about what people should be eating. The latest dietary guidelines, published on Jan. 7, 2026, have received mixed reviews from nutrition experts.
Sugar alcohols aren't inherently worse than regular sugar, they're just metabolized differently. Regular sugar is fully digested and predictably raises blood sugar levels. Sugar alcohols like erythritol are only partially absorbed, so they typically provide fewer calories and have a smaller impact on blood sugar, although some types can still raise it modestly.
Rachel Swanson, a registered dietitian at LifeSpan Medicine and author of "Trying!: A Science-Backed Plan to Optimize Your Fertility," splits her time between New York City and Miami, spending about half the year in each. She also takes small-group workout classes three times a week, focusing on strength training. She says eating enough nutrients, especially protein for muscle-building, is crucial for her. She generally aims for around 0.7 grams of protein per pound of body weight, the protein intake usually recommended for physically active people.
We compared how participants fared while eating their habitual diets with how they responded to the two diets that were low in ultraprocessed foods. During the periods when participants ate fewer ultraprocessed foods, they naturally consumed fewer calories and lost weight, including total and abdominal body fat. Beyond weight loss, they also showed meaningful improvements in insulin sensitivity, healthier cholesterol levels, fewer signs of inflammation, and favorable changes in hormones that help regulate appetite and metabolism.
Gut bacteria are crucial to ensuring healthy digestion and defecation. But two species of bacteria may also be the cause of constipation: according to a new study, Bacteroides thetaiotaomicron and Akkermansia muciniphila appear to work in concert to break down colonic mucin, the slimy coating in our colons that keeps our poo moving along. Too little mucin means a drier and more constipation-prone colon.
The ad leans into the truth about Raisin Bran that, for decades, it tried to obscure with messaging about its plentiful raisin content: This cereal makes you poop. I'll admit: I laughed. I can't deny a good poop joke, and its frankness about the reason some people enjoy bran cereal reminded me of my favorite SNL sketches for " Colon Blow" cereal.
As hormones shift during the transition into menopause, many women notice that their energy levels react differently to carbohydrates than they did in earlier years. Muscle mass tends to decline with age when strength training is absent from a routine. Because muscle mass determines how the body uses glucose, maintaining it through regular activity may support steadier daily energy.
Rather than simply extending the fasting window or cutting more calories, the intervention group was simply asked to finish eating at least three hours before their usual bedtime. That meant no snacking while watching TV after dinner and no "just one more bite" at 10 p.m. (my personal downfall). This relatively simple intervention ensured that the overnight fast overlapped with the body's natural sleep-wake rhythm.
By following more than 100,000 people in the U.K. for years, researchers found that people whose food choices scored high in any one of five diet categories tended to live longer than people who scored the lowest. Specifically, the team found that even after adjusting for confounding factorssuch as whether people smoked, how much exercise they took and what their education and ethnicity wasstudy participants who tended to eat according to any one of the five diets were 18 to 24 percent less likely to die of any cause. For women, that roughly translated into an extra 1.5 to 2.3 years of life. And for men, it added about 1.9 to three years.
