Great Topic: I am certainly torn on this and the science will support different points of view. I am blessed that I have ZERO disease in my family. No cancer of any kind, no heart disease, etc.. And if you ask my family why this is.....they will tell you it is from eating mainly vegetables (My family were farmers) My mom tells me stories of my grandpa saying meat is too expensive. She has very little memories of eating meat. The meat they did eat was venison killed by my grandpa(whitetail) I do think their is something to eating as much vegetables and limiting meat.
On the other hand, I also believe wild game meat provides benefits far beyond the studies of raised cattle beef. I sure hope so, because I eat meat taken my bow year around and almost at everyday.
BTW, I just saw a story on Tom Brady and his wife diets. 80% Veggies/Fruits 10%-20% meat. They believe to be supple, injury free and live a healthy life, fruits and veggies are the way to go. Hard to argue with him given his level of play and how they both look at their age.
