Human dietary patterns are heavily influenced by geographic latitude, with more plant food available near the equator and more animal food in the Arctic.

“the data that that I've seen indicate that basically the further you go from the equator the greater the animal and lower the plant consumption you get up into the Arctic and plants are equal to or less than five percent of calories you get down to the equator and animal foods bottomed out at 36 percent of calories”

“so we did regression analysis on the plant animal subsistence ratio and exactly as you predicted as you move in latitude what happened is plant food is replaced by more fish food animals food stays about the same”

“as you move in latitude what happened is plant food is replaced by more fish food animals food stays about the same”

“but when i look at the anthropology i'm like okay people hunt and gather and what they hunt and gather is based a lot of is based almost entirely on where they are and and in particular like latitude because you get down toward the equator there's just so much more plant food and you get up toward the arctic and there's just so much more animal food dominant in the diet right”
