Highlights
•
Identical twins on a vegan diet showed lower LDL, lower insulin, and more weight loss in just 8 weeks
Gardner: in the Stanford twin study, the twin on the vegan diet showed significantly lower LDL cholesterol (-13.9 mg/dL), lower fasting insulin (-2.9 mU/L), and more weight loss (-1.9 kg) compared to their genetically identical sibling on the omnivore diet after just 8 weeks.•
Diet quality is the common denominator — both vegan and omnivore improve health when whole-food based
Gardner: the most important finding of the twins study isn't that vegan beat omnivore — it's that both groups improved dramatically when switching to whole, minimally processed foods. The quality of the diet matters more than whether it includes animal products.Was this useful?
