Yeah there are supposed to be specific beneficial foods for each type. My doc gave me a 5-page handout for Type A. I did a quick google for O's and it seems that you're meat eaters/high protein, but didn't list specifics. But my doc didn't categorize people like that. I could be a meat eater, too, but have to avoid bacon (mmmmm), beef (mmmmmm), and liver (fine by me).
I think if you look at the book "Eat Right 4 Your Type" it lists all the specific foods.
But again....I'm not totally endorsing this program cuz I don't know anyone who's done it.....hence this thread......
I'm not O-, but a number of people I know are... I was more asking because as a universal donor I'd think the O- diet would be fairly similar to all the others. I'm suspicious that it's not.
