I'm not a vegetarian, but I'm attempting to follow the Mediteranean diet which calls for a very small amount of red beef, chicken and fish with emphasis on fruits, vegetables and whole grains to eat. I've known about the Blood Type Diet s for about 5 years. I think this might be a fad or because of the fillers, hormones and Antibiotics animals are given, if one can't obtain natually fed animals, beef and chicken should be limited. That smacks in the face of what we are encouraged to eat as people who have type O blood. There's a lot of confusing information for us to discern.
