Valkyrie, your statement that "our bodies require some animal protein to maintain optimal health" is pure hogwash. Numerous biological and medical studies have conclusively demonstrated that a well-planned and balanced vegetarian or vegan diet is at least as healthy as a diet that includes meat, if not more healthy.
If you want to eat meat, fine. But if you want to make yourself feel better about it by telling yourself you have to, sorry, but that ain't gonna fly. Not in the age of the supermarket hunter and gatherer.
With a statement as inaccurate as Valkyrie's, I really don't understand how his/her letter was an "Editor's Choice."
