A Vegan Diet May Have Genetic-Level Benefits for Aging
Stanford researchers behind the Twin Study have used their data to compare the effects of a vegan diet and a omnivorous diet on aging in identical twins. After only eight weeks, twins assigned to follow the vegan diet showed significant changes in certain genetic markers that indicated slower biological aging than their omnivorous, genetically identical sibling.1 The vegan twins also ate fewer calories, lost weight, and improved their LDL cholesterol and fasting insulin levels.2
