Research going back decades shows adding more fruits, vegetables, and non-animal sources of protein helps us live longer, healthier lives.

A study featured in the Netflix docuseries You Are What You Eat: A Twin Study took that to the next level.

Stanford researchers asked 22 sets of identical twins to go 8 weeks eating a healthy, varied diet and regularly exercising. One twin ate an omnivore diet, the other vegan.

On this week’s episode of Well, Now we talk to the lead researcher of the “twin study” Christopher Gardner on his findings and whether we really all need to go vegan to stay healthy.
