Organic Chicken breast might be a healthier source of protein then my Blocks of soy, but I'm still not eating animals. There is no such thing as a "Meat Deficiency". But most people eat meat because they like it, not because they think they need it?
I wouldn't say any animal products are healthy for us. In researching diet and nutrition, more and more it seems to be that higher meat intake is associated with higher rates of disease. While diets containing more plant foods are less likely to cause disease, they also have the ability to ease unpleasant symptoms of some diseases while reversing other diseases altogether.
I think most people enjoy eating meat, and that's why they defend it. When the ethical/moral topics arise on the other hand(whether or not we brought them up
), "I like eating meat" doesn't seem to cut it. I think they just use "we need meat" as an obviously justified reason for eating it. Guess we're not good enough proof otherwise
