A small study links regular coffee drinking to differences in how the digestive system works, although the health implications remain unclear.
New research finds that some of the peels, skins and stalks we routinely throw away contain more fiber than the parts we eat.
Despite eating more fiber, vegans had fewer types of gut bacteria than meat eaters in a new study, but other findings suggest their gut health wasn't necessarily worse.
A new study suggests inflammation can disrupt gut bacteria that help process certain foods, which may help explain why some people with IBD develop new food-related symptoms.
A new study suggests the same plant-based carbohydrates may affect people differently depending on which microbes are already living in the gut.
In stem cell transplant patients, eating more sugar-rich foods while taking broad-spectrum antibiotics was linked to greater disruption of the gut microbiome.
A mouse study suggests diet may influence how well some cancer treatments work by changing the gut microbiome, but the findings are not a reason to adopt a high-fat diet.
National data show more Americans are taking probiotic supplements, while fiber intake has changed little over more than a decade.
A new review finds that changes in iron absorption, protein use and digestion may help the body adapt over time.
A small human study found connections between the gut microbiome and chemicals measured in different parts of the brain, offering new clues about the gut-brain connection.
Researchers found that gut microbes can combine nitrate and iron into new compounds that improved blood pressure, blood sugar and liver fat in mice.
A study in mice points to a possible way the amino acid leucine could help gut bacteria produce a compound that supports the intestinal barrier, but researchers have not yet tested the approach in children.
Six of 15 adults tolerated more peanut months after treatment, but the experimental therapy did not eliminate their allergies or prove a lasting cure.
In a six-week company-funded trial, a powdered blend containing more than 30 plant ingredients produced broader microbiome changes than a single-strain probiotic, but broader changes do not necessarily mean better health.
Two laboratory studies suggest the microbiome is only part of the story, while offering early clues about how fiber and hard-to-digest plant proteins may influence the chemicals produced in the gut.
A preliminary product analysis found that prebiotic sodas generally contain less sugar than regular soda and more fiber than other soft drinks, but their benefits depend heavily on what they replace.
An athlete-focused review explores how shifting sleep and meal schedules may affect digestion and gut microbial rhythms, but direct evidence in travelers remains limited.
A laboratory study found that some low-calorie sweeteners affected bacterial growth differently when combined with medications, caffeine and other common compounds.
A broad review found promising biological clues, but it did not establish that any food, compound or diet prevents Alzheimer’s disease.
The findings do not show that the amounts commonly found in food harm the human gut.
A preclinical study identified a possible pathway linking short-term fasting, the gut microbiome and intestinal regeneration, but it does not show that cancer patients should fast before treatment.
A large genetic study links irritable bowel syndrome to triglyceride regulation and liver metabolism, but the findings do not show that changing blood fats can treat IBS.
A global analysis found children and teens are eating low amounts of fruits, vegetables, beans, legumes, nuts and seeds, with a notable decline in the United States after infancy.
A study of 150 infants found similar growth and nutrient intake with baby-led weaning and conventional spoon-feeding, but researchers say readiness, food variety and choking safety still matter.
A new study suggests some gut bacteria may get an advantage during weaning because they can use both breast milk sugars and fibers from solid foods.
