Four Weeks of a Vegan Diet Alter Signs of Inflammation and Aging

A four-week vegan intervention in 48 healthy adults produced measurable epigenetic changes at over 800,000 DNA methylation sites, reducing mTOR activity and enhancing insulin, stress-response, and healthy-aging pathways. The vegan group also showed fewer neutrophils and more CD4+ T cells, indicating a shift toward a less pro-inflammatory immune profile.
