Aaron Hartman, MD examines whether strict diets like veganism or carnivory can last across generations. He points to the Maasai and a Colombian tribe as examples: their diets and microbiomes shift seasonally with what's available, and there's no historical record of multi-generational exclusive vegan or carnivore cultures.

Long term. Do we have any cultures in the history of the world where vegan grandmothers are having vegan mothers or having vegan daughters? And the answer is no. Do we have any culture in the history of the world where carnivore mothers are having carnivore children? Are having carnivore kids? And the answer is no. People are referred to the Maasai or other tribes in Colombia, for example. But it's interesting how when they've gone back and visited those tribes at different times of the year, their diets changed. And so there's this one thing about this group in Colombia, like, oh my gosh, they have the most amazing microbiome. All eat is like nuts and seeds and from 10, 15 years ago and they're revisited five, 10 years later and they went to a different time of year and they were hunting monkeys and eating animals and because its season was different and I was like, oh, that's interesting. Their microbiome changes seasonally with what they eat.
