Some of need to eat animal foods to live because genetics. I am of Sami heritage and I am tired of people telling me my genetics are the problem.

your infinitesimally rare edge case is not a negation of the comment you are responding to. Also I don't think there is even any good evidence that some people have genetic heritage that means they can only eat animal foods

Where I can learn more about the genetic need of people of Sámi heritage to eat animal food?

When I tried to search for the details, I found only that it was a traditionally meat heavy diet.
