Here is a nice positive article about vegetarianism, entitled "Protein a key concern for vegetarians"
It's very positive about vegetarianism. It talks about a restaurant in Atlanta called Cafe Sunflower -- I've been there and it's delicious.
But, I disagree that protein is a "key concern" for vegetarians. Anyone who consumes a balanced vegetarian diet will get plenty of protein. We only need 10% of our calories from protein. Most Americans are well in excess of that.
And why don't we talk about the "key concerns" of the standard American diet -- obesity, diabetes, heart attacks, stroke, osteoarthritis, hypertension, high cholesterol........ ???
