How do diet, smoking, alcohol, and stress reshape the female microbiome?

This review examines how modifiable lifestyle and environmental factors shape the female vaginal, gut, oral, and skin microbiomes, with diet, alcohol, smoking, obesity, stress, hygiene, physical activity, and sexual behaviours all linked to site-specific microbial shifts. It argues that understanding these patterns could help guide future female-focused prevention and intervention strategies.

Whole wheat diets may reduce the risk of inflammatory bowel disease

Enriching the diet with wheat fiber protects mice against intestinal inflammation, according to a study published by researchers in the Institute for Biomedical Sciences (IBMS) at Georgia State University.

Alcohol intake linked to lower micronutrient intake in men with type 2 diabetes

Researchers analyzed 1,565 Japanese outpatients with type 2 diabetes and found that higher alcohol consumption was associated with lower intake of several micronutrients, particularly potassium, calcium, and vitamins A and C, in younger men. The study also linked alcohol intake to a savory dietary pattern rich in rice, meat, fish, and seasonings, highlighting age- and sex-specific nutritional risks.

Pomegranate’s hidden fiber-bound polyphenols significantly increase total antioxidant capacity

Researchers showed that pomegranate fruit extract contains substantial levels of non-extractable polyphenols bound within its fibre-rich matrix, significantly increasing its total measured antioxidant capacity. In human neuronal and astrocytic cell lines, the extract reduced hydrogen peroxide–induced oxidative stress, particularly in astrocytes, under in vitro conditions.

Low-fiber diets quickly impair emotional memory in aging brains

Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged brain – and the effect can happen fast, after just three days of poor eating.

Gut microbiome may shape response to GLP-1 drugs, new review suggests

This review examines how GLP-1 receptor agonists and the gut microbiome influence one another through bile acid signaling, short-chain fatty acids, and inflammatory pathways. It explores how microbial composition may shape treatment response and highlights the need for controlled human studies to enable microbiome-informed precision therapy.

Research suggests bamboo-based foods could support metabolic health

This systematic review synthesizes human, in vitro, and food-processing studies on bamboo consumption, finding limited but suggestive evidence for metabolic, digestive, and antioxidant benefits when products are properly prepared. It also highlights safety considerations, including potential goitrogenic effects from inadequately processed shoots, and calls for higher-quality human trials.

Simple fruit granola intervention shows promising cardio-renal signals in CKD patients

A single-arm intervention study in Japanese adults with moderate chronic kidney disease found that replacing breakfast with fruit granola for two months lowered systolic blood pressure, reduced LDL-related lipid markers, and decreased a urinary marker of tubular injury. Renal function remained stable, bowel habits improved, and findings were exploratory due to the small, open-label design.

How Traditional Chinese Medicine may reshape the gut microbiome to ease insulin resistance in PCOS

This review synthesizes evidence that gut microbiota dysbiosis contributes to insulin resistance and symptom severity in polycystic ovary syndrome through impaired barrier function, inflammation, and altered microbial metabolites. It evaluates how Traditional Chinese Medicine may modulate these pathways while highlighting major gaps in clinical validation, safety, and standardization.

National study maps where food additives come from in children’s and adults’ diets

By analysing nationally representative diet data, researchers show that food additives rarely occur alone, with children and teenagers experiencing the highest exposure to complex additive mixtures largely driven by ultra-processed foods.
