A Month of Vegan Eating Linked to Lower Inflammation and Hints of Slower Biological Aging

A small randomized trial of 48 healthy adults found that following a vegan diet for four weeks reduced inflammation and altered DNA methylation in pathways related to aging, with some aging measures (epigenetic clocks) suggesting slower biological aging. Results are preliminary and limited to blood markers; the short duration and small sample mean findings may not generalize, and longer, larger studies are needed. Diet quality also matters in vegan eating.
