Clear, sourced reviews of research examining the relationship between vegan diets and health.
In the UK Biobank cohort, 416,584 adults free of kidney disease were followed for an average of 12.9 years. Vegetarians had a 19% lower risk of a chronic kidney disease diagnosis than high meat eaters. The study is observational, and its vegetarian group contains only 367 vegans.
Five publicly available chatbots were given the same 58 vegetarian and vegan nutrition questions. Every product produced answers that trained reviewers judged potentially unsafe, and the flagged answers clustered on vitamin B12, iodine, selenium, pregnancy and symptoms needing a clinician.
A cross-sectional study in Nutrition Bulletin recorded eight days of food intake from 66 Australian vegans. Protein and macronutrient balance were within recommended ranges, while vitamin B12, calcium, iodine, selenium, zinc and long-chain omega-3 fats often fell short, even with supplements.
A randomized trial in The American Journal of Clinical Nutrition compared a self-selected vegan diet, a usual omnivorous diet and a vegan diet with resistance exercise in 72 adults over 65. What it found, what it does not show, and a practical note on protein and strength training.
Study types, confounding, relative versus absolute risk and a one-minute checklist: a practical guide to reading nutrition studies and headlines without being misled.
