Blood Type A (40% of USA) no dairy, no red meat, veg. fish ok
Blood Type O (50% of USA) no bread, no dairy, meat and fat ok
Blood Type B (9% of USA) no chicken, no corn
Blood Type AB(1% of USA) a varied diet ok
There are lots of other things you should avoid in each blood group. Type O very long lived, often found in jail, higher percentage dies in accidents.
Type B capable of stress and 2nd longest life, dies of stroke.
Type AB prone to autoimmune diseases
Type A dies early due to cancer and heart disease.
These are generalizations. I'm a B and I still eat some chicken.
Interesting! Thanks for pointing to the book. Wonder if my local library can get a copy. I’ll have to put that on my list.
