Why the yearning for the "good old days?" BTW, what "good old days" are we talking about? The 1600's? The 1000's? 5000 BCE?
It is not really about the food per se in an ancestral diet that is good or bad. It is is about the fact that the ancestral food items, largely consisting of items that were in continuous abundance and constituted prey for humans, megafauna, pressured our bodies to optimize for those items.
This is why today all, as in every single one of the essential nutrients can be found in high bio-availability in animal items.
