How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

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.

Culturally tailored food programs significantly lower blood pressure in minority adults

Black and Hispanic adults with high blood pressure (hypertension) who received a culturally tailored food-based intervention with dietitian coaching experienced a significant drop in blood pressure compared with those who received an equivalent amount of fresh produce without additional supports, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Higher sugar intake raises gallstone risk in adults, study finds

A cross-sectional NHANES study of 8,975 U.S. adults found that higher total dietary sugar intake was associated with higher odds of gallstones, with each 100 g/day increase linked to a 41% rise after full adjustment. The findings suggest sugar intake may be a modifiable gallstone risk factor, but the study relied on self-reported gallstones and cannot establish causation.

Home-delivered DASH diet improves blood pressure and cholesterol outcomes

Black adults with high blood pressure who received dietitian counseling and home deliveries of groceries aligned with the DASH diet—meaning high in fruits, vegetables, whole grains, low-fat dairy, nuts, seeds, legumes and lean proteins—had an average overall reduction in systolic blood pressure of 7 mm Hg at three months overall and a 5 mm Hg reduction compared with participants who received only basic dietary guidance and a grocery stipend, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

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.

Men show major gaps in male fertility knowledge, study finds

A study of 156 adult men found that knowledge about male fertility was generally low across both medical and lifestyle-related topics, with only 5 of 25 questions answered correctly by most respondents.
