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.

New analysis reveals flaws in traditional BMI classification system

Research from Italy to be presented at this year's European Congress on Obesity (ECO 2026, Istanbul, Turkey, 12-15 May) and published in the journal Nutrients shows that when the gold standard technique of dual-energy X-ray absorptiometry (DXA) is used to measure body fat in the general population, it shows that the traditional WHO body mass index (BMI) classification system misidentifies significant numbers of people as having overweight or obesity.

Higher meat intake may slow cognitive decline in older adults with APOE ε4

In older Swedish adults, higher meat intake was associated with slower cognitive decline and lower dementia risk among people carrying APOE ε3/ε4 or ε4/ε4, but not among other genotype groups. A higher processed-to-total meat ratio was linked to worse dementia outcomes, while unprocessed red meat and poultry showed no substantial difference.

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.
