I think you hit it on the head with "the majority of traditional grocery stores." For me those just aren't the place to shop for animal products like meat and dairy. Hit the specialty places for that, pay the premium, and eat less of it. Maybe this one study debunks all the rest of the data out there about red meat, maybe not, but it's a healthy lifestyle that works for me; I only pay to eat meat once or twice a month as a result.

There's one other source of good meat: hunting. I suck at that but I have friends and associates who hunt and they are often trying to get rid of extra meat. Always happy to help with that :)
