We've all read about the need for more Omega-3's, vitamin D-3, etc., but there is (it seems to me) very little discussion about protein deficiency. Maybe that's because we live in a society where protein sources are clearly plentiful, but much of our "health consciousness" media output urges us to consume foods that are not rich protein sources. What is the real story on protein - how much do we need, and how can we get it?
