BTW, this article suggests that legumes have some positive effect on longevity, fish might have a smaller such effect, meat may have a negative effect, alcohol has a rather broad confidence interval (which I suspect is because they’re trying to model a non-monotonic effect with a linear model), and none of the other food groups they considered have much of an effect.
I would guess that legume consumption is positive for the elderly because their folate absorption declines with age (along with other B vitamins like b12). I wonder if anyone has tried to test that yet.
