One thing I have to say is that the meat (red or otherwise) they ate (I assume you mean primitive man) was very different from what we eat today because of animal husbandry practices. I think probably the healthiest thing people could eat would be wild game, much less fat and of course no antibiotics and such. However, most people don’t have access to that anyway.
I thought about this. However, I’m just very damn tired of people telling individuals HOW they should live, WHAT they should eat. What you may not realize is that academics do for a living is mostly whore their knowledge. Many times, they are looking for grants, money from people or government with other issues in mind (like total control and domination) to subjugate freedom. Academics thrive on publication, grants, studies, contracts, ‘research - usually in the guise of research, anyways’ and brains for sale to anyone who pays. Look at the ilk in our colleges and universities polluting the minds of our children....you just can believe anything they say any more...I know a lot of this for a fact.....
