Vegan medicine is becoming an accessible and powerful therapy. For a recent meta-analysis of studies researchers analyzed nearly 100 studies relating diet and disease. Overall, reductions in body mass index, total cholesterol, LDL-cholesterol, and glucose in vegetarians and vegans compared to omnivores were identified. When only the 10 prospective cohort studies were included, ischemic heart disease (heart attacks) were reduced by 25% and total cancer by 8%. When the analysis was limited to vegans, total cancer incidence was reduced by 15%.
