Do vegans live longer than meat eaters?
Besvaret 27. oktober 2026
Research shows no clear difference in lifespan between vegans and meat eaters, and most of it comes from studies that show links, not causes. A British analysis of two large population studies with more than 5000 deaths found no reliable difference in overall death rates between diet groups. An older pooled analysis of five studies, described in a review, found lower death rates in vegetarians, fish eaters and occasional meat eaters, but not in vegans. One of the authors of both is a member of the Vegetarian Society and the Vegan Society.
For unprocessed red meat, an American analysis tried 1208 different ways of analysing the same data. Only 48 gave a result unlikely to be chance, and 40 of those pointed to lower death rates. Processed meat is linked in several meta-analyses to type 2 diabetes and heart disease. That review was paid for by MatPrat, the Norwegian meat and egg industry's information office.
