Study seemed to take a lot into account, is it really that outrageous of a finding? Fruit and vegetables have a lot of known benefits.
We evolved from apes where most of our group are frugivores or herbivores. Hell, if our bread wasn’t fortified with things like niacin and vitamin c most people would have scurvy and tons of other crap wrong with them. We probably should get more of our vitamins from the source!
