Apes eat everything in the wild, so anything we eat is ape food.
Also, us being apes means anything we eat is ape food.
Please make sense.
That's just a tautology.
It's not as simple as saying we are apes. Home Sapiens is a seperate species in the genus Homo in the subtribe Hominina, in the tribe Hominini, in the sub-family Homininae in the family Hominidae.
Only at the Hominini tribe level and above are there any living relatives - chimps. From there down to the species level only humans now exist. Hence chimps are thought to be our closest living relative. Co-indidentally or not, chimps are unusual in that they eat meat. Other members of the Hominidae family (higher up the tree) have diets specific to their species. E.g. some just eat fruit.
There is no overarching "ape food" that covers all members of the family.
Just being a separate species is enough to allow animals to eat very differing diets depending on where they evolved. This is true amongst many animals, not just primates. So there is little mileage in claiming we should eat a diet based on the diet of different species just because we are in the same taxonomic family.
