Sorry I have to disagree with you. And there are far more kinds of meat...
... than just RED meats. Or do you count chicken, pork and the many kinds of seafood as RED meats as well?
As I said before, too much of anything is bad for you, no matter what it is.
Meats include the kinds of proteins and amino acids needed to aid intelligence. Meats include materials that enhance the body's abilities to process other foods. Humans are Omnivores--not herbivores. To eliminate meat from our diet is to eliminate half of what makes us what we are.
But please note that I'm not arguing that we should all eat a 100% carnivorous diet, either. Just as our bodies need meat, our bodies need the minerals and vitamins obtained through grains and leafy foods as well. Our bodies can use the proteins gained from legumes and beans and other plant foods as well. The ideal diet is a balanced one that should include roughly equal amounts of each of the different kinds of foods.
Please stop believing that there is a "one food does all" solution; there simply isn't one.
