Microbiome

The varied community of microorganisms that live in different parts of the body, particularly the gut, is referred to as the human microbiome. These microorganisms are mostly bacteria, but they can also be viruses, fungi, and archaea. These microbial communities are vital for immune regulation, nutrition synthesis, digestion, and pathogen defense. Metagenomics research has shown that homeostasis depends on a healthy, diverse microbiome, whereas dysbiosis, or imbalances in the microbiome, is linked to a variety of illnesses, such as obesity, inflammatory bowel disease, allergies, and neuropsychiatric disorders. The field of microbiome research is growing quickly, providing new information on diet-microbe interactions, probiotic treatments, and personalized medicine.

Heavily processed foods may raise heart disease risk beyond poor nutrition alone

A 2026 review in Cardiology in Review reports that higher intake of ultra-processed foods is consistently associated with greater risks of cardiovascular disease, stroke, and cardiovascular mortality across cohort studies and meta-analyses. The paper also highlights plausible mechanisms involving gut dysbiosis, oxidative stress, and NF-κB-driven inflammation, with additives such as emulsifiers, preservatives, dyes, and sweeteners discussed as potential contributors.

Vitamin D may help shape how the immune system responds to gut bacteria in IBD patients

Vitamin D supplementation may help shape how the immune system responds to gut bacteria in people with inflammatory bowel disease (IBD), according to a Mayo Clinic–led study published in Cell Reports Medicine.

Genetic study maps bacteria’s protective armor behind severe infections

The first large-scale genetic study of E. coli's protective armor has identified the five capsule types that are responsible for 70 per cent of all multidrug-resistant bloodstream infections in Europe.

Wholegrain rye changes gut bacteria and lowers inflammation in obesity trial

In a 12-week randomized trial, replacing refined wheat with wholegrain rye in a calorie-restricted diet did not produce greater weight loss in adults with overweight or obesity. Wholegrain rye did, however, lower C-reactive protein and alter gut microbiota and short-chain fatty acids in ways that may have positive cardiometabolic implications.

Gut microbes drive fat browning in response to diet

White adipose tissue stores energy, while brown and beige fat burn energy through thermogenesis. Under certain environmental conditions, white fat can transition into beige fat in a process known as browning.

U.S. study links ultra-processed foods to lower odds of fertility

A cross-sectional NHANES study of 2,582 U.S. women found that higher ultra-processed food intake was associated with lower odds of being classified as fertile based on self-reported infertility history. Greater Mediterranean diet adherence was linked to higher odds of fertility in adjusted models, but that association was no longer significant after accounting for obesity.

Why do some people respond better to GLP-1 drugs? Gut microbiome may hold clues

A review in the Canadian Journal of Physiology and Pharmacology examines emerging evidence linking glucagon-like peptide-1 receptor agonists (GLP-1 RAs), the gut microbiome, and obesity treatment outcomes. The authors conclude that microbiome changes seen during therapy are most likely driven by diet, behavior, and weight loss, although microbial profiling may eventually help predict patient responses.

Scientists show gut bacteria can reach the brain in mice and reveal a potential vagus nerve pathway

Researchers found that very small numbers of gut bacteria can translocate to the brain in mice, particularly when gut barrier permeability increases due to a Paigen diet. Evidence suggests the vagus nerve may serve as a partial route for this gut-to-brain microbial movement.
