I understand that red meat is bad for some people's gene pool.
Sounds like bullshit to me. Some inflated theory, and yeah maybe there is some genetic condition that has been exacerbated by modern practices that contribute to some weird anomaly.. but should not be discussed as if red meat were bad, merely because some genetic weirdness causes such a condition in some 1/10 million people.. if it is even true.
Not some modern practice, but generations of food/climate/social norms/genetics. It's not my idea, read "The Blue Zones" (I did) by Gianni Pes and Michel Poulain outlined in the Journal of Experimental Gerontology. They discuss five different cultures in different parts of the world that have extremely high percentage of nonagenarians and centenarians. On the Italian island of Sardinia (one of the Blue Zones), they have 30 types of bread. That could be bad for a different type of person.
I found it interesting that the only Blue Zone in the USA is a community of about 9,000 Adventists in the Loma Linda, California area are the core of America’s blue zone region. They live as much as a decade longer than the rest of us.
