A new national analysis finds U.S. adults are using more supplements, with growing interest in products marketed for immune, gut, skin, joint and inflammation-related health.
A new model suggests gut microbes help shape how much energy the body absorbs from food, adding nuance to the way scientists think about calories, fiber and metabolic health.
A new observational study in remote Amazonian Indigenous communities found that gut microbial diversity changed after medical visits, but the findings do not mean lifesaving treatment should be avoided.
A mathematical modeling study suggests vitamin C may reduce certain cancer-linked chemical reactions during digestion, but it does not prove that supplements prevent cancer.
A major genetics study suggests body weight can shape gut bacteria, but researchers say your microbiome alone does not determine whether you develop digestive disease.
New research found that people newly diagnosed with type 2 diabetes had sharply higher post-meal glucagon levels tied closely to fatty liver disease, raising new questions about how early metabolic dysfunction develops.
A new clinical study suggests an experimental treatment may help reduce some harmful effects of accidental gluten exposure, though it is not a cure.
New guidance from gastroenterology experts says fiber and less straining are the strongest first steps, while evidence for some common remedies remains limited.
A new analysis finds that microbes contribute a meaningful share of the protein in foods like yogurt, cheese and bread.
Researchers found similar symptom relief from a low FODMAP diet and a common antibiotic, with gut bacteria differences helping explain why some people respond and others do not.
New research shows how compounds in breast milk support a delicate microbial balance, including bacteria often seen as harmful.
A small human study found links between coffee, mood and the gut microbiome, but it does not prove coffee improves mental health.
A large international study finds distinct gut bacteria patterns in people with Parkinson’s and in some who have not developed symptoms yet.
A new study links the “neuroactive potential” of gut bacteria to cognition and depression in older adults, though the findings are observational and do not show cause and effect.
Early animal research suggests potential gut and gene effects, but what it means for people remains unclear.
Early lab research suggests certain high-fat diets could disrupt key protective cells in the gut within days, though the findings come primarily from animal models.
A new legal petition calls for labels on foods like bacon and hot dogs, raising questions about what the science actually shows.
New research suggests some people may not be able to fully use dietary fiber without the right gut microbes.
A small human study suggests vitamin D supplementation may affect how the immune system interacts with gut bacteria in people with inflammatory bowel disease.
A mouse study suggests fiber in whole wheat foods may support gut health by triggering anti-inflammatory responses through the microbiome.
A new study finds people who spend more time in nature tend to eat more fruits and vegetables, though the connection may come down to stress, mood, and daily habits
A small community study found that asking parents to document local food environments with photos helped shift how they thought about food marketing, children’s diets and the choices available to families.
Researchers found that changes in the gut microbiome linked to a high-fat diet allowed small numbers of bacteria to travel to the brain in mice, pointing to a possible new pathway connecting diet and neurological health.
New research shows specialized immune cells actively train the body to tolerate common foods such as corn, wheat and soy, offering clues that could one day help prevent food allergies.
Researchers found that people with higher levels of the gut microbe Roseburia inulinivorans tended to have greater muscle strength, and experiments in mice suggest the bacterium may influence muscle fibers.
