This is really THE most thorough and well-supporter research on the human diet, and you're just plain wrong. I could link a lot more research, but you can easily find it by digging through that website a bit, and I doubt you'll even look at the link in the first place.

In short:
"Abundant research shows it's important to eat enough protein, but there are many ways to get that protein, and some are more healthful than others. People who limit how much meat they eat tend to have lower risks for chronic diseases. Plant protein sources (beans, lentils, soy foods, nuts, seeds) and seafood offer the most health benefits. Getting enough protein, along with physical activity, is important for staying strong, healthy, and independent."
