The diversity of diets in long-lived populations suggests the human body can manage a variety of dietary conditions if energy balance and metabolic health are maintained.

“but their diets are actually quite diverse so what does that tell us right so if you have you know people in Japan and people in Switzerland and people in this part of Africa and people in this part of the Arctic or whatever where you see reasonable pockets of longevity but their diets are relatively diverse it might be interesting to look at what's missing from all of the diets or what do they have in common in their absence or what do they have in common in their presence but to me at least it suggests that there's probably a pretty robust nature within the human to manage a variety of different dietary conditions again it comes down to provided energy balances met and I think provided that a person stays metabolically healthy”
