Adventist Health Study-2

In plain English

Loma Linda University has followed roughly 96,000 Seventh-Day Adventists — a population spanning vegan, vegetarian, pesco-vegetarian, semi-vegetarian and omnivore — for over a decade. Across cancer, type 2 diabetes, cardiovascular disease and dementia, the more plant-based the diet, the lower the risk. Vegans showed the lowest all-cause mortality.

Why it matters

Vegans had the lowest mortality, ischaemic heart disease, T2D and cancer rates across the diet spectrum.

Caveats

Adventists differ from the general population in smoking, alcohol and church-community ties — some of the benefit may be lifestyle, not diet alone. Self-reported diet via FFQ has known measurement error.
