Gastrointestinal Health

This hub offers a comprehensive resource on gastrointestinal health, digestive diseases, and the human microbiome, drawing together authoritative articles on basic science, clinical management, and emerging research. The collection addresses the pathophysiology, diagnosis, and treatment of major gastrointestinal disorders, including irritable bowel syndrome, celiac disease, inflammatory bowel disease, and gastroesophageal reflux, while also exploring surgical, dietary, and pharmacological interventions. Special emphasis is given to the role of the gut microbiome in health and disease, including its influence on immunity, metabolism, neurological function, and response to therapy. Readers will also find up-to-date insights into microbiome-related interventions, such as fecal microbiota transplantation, as well as practical guidance for dietary management and prevention. This hub serves as a trusted reference for clinicians, researchers, and individuals seeking an evidence-based understanding of digestive and microbiome science.

Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.

Stanford scientists map the molecular diversity of different global populations

Researchers at the Stanford School of Medicine have found that ethnicity and geography may influence human molecular makeup - from metabolism and immunity to gut microbiota and biological aging.

New research maps the biological toll of drinking

A new review published in the journal Addiction confirms drinking causes substantial harm to health. Some of those harms may be reversible if the person reduces or stops drinking.

Adult weight gain strongly linked to higher obesity-related cancer risk

New research presented at this year's European Congress on Obesity (ECO 2026) in Istanbul, Turkey (12-15 May) shows that people who gain the highest amount of weight across adulthood are at greatly increased risk of certain obesity related cancers.

Too little or excessive sleep may accelerate organ aging

An analysis of biological clocks throughout the human body suggests that too few hours of sleep-and too many-may speed aging in the brain, heart, lung, and immune system and is associated with a wide range of diseases.

Do repeated football head hits disrupt the gut microbiome?

A small exploratory study of collegiate football players found that non-concussive head impacts are correlationally linked to acute and season-long shifts in gut microbiome composition, with changes most pronounced 48–72 hours after significant impacts. However, most associations weakened after correction for multiple testing, and the authors stress the findings are preliminary and hypothesis-generating.

Engineered regulatory T cells offer a path toward immunosuppression-free transplants

Organ transplantation remains the cornerstone treatment for end-stage organ failure. While conventional broad-spectrum immunosuppression effectively controls acute rejection, it fails to address chronic rejection and carries long-term side effects including infection, malignancy, and metabolic disorders.
