As a rule, people tend to eat whatever food they can physically access. Transcontinental shipping now allows us to access all sorts of foods – we can eat durian in California, jasmine rice in Alaska, Spam in Hawaii, and Russian caviar in Cape Town – but for most of (pre)history, humans ate only locally available foods. So it’s no surprise to hear that hunter-gatherers, past and present, ate and eat wildly varied diets depending on their environment. The East African Hadza diet is different from the Arctic Inuit diet is different from the Paraguayan Ache diet.
This is usually highlighted by critics as a counterpoint to the tenets of ancestral health. Because apparently we’re all convinced that a single, rigid dietary prescription is the One True Diet. That’s silly, of course.
