In Eat Right for Your Type, the author, Dr. Peter D’Adamo suggests that digesting and absorbing food is different for each blood type and eating foods that are incompatible can cause inflammation, metabolic impairment and disease. One major factor in this process is that many foods have protein molecules called “lectins”, and each body interacts with them differently, depending on blood type.
The four blood types are O, A, B, AB. Type O is the oldest blood type and therefore the diet includes a large amount of meat and few grains, legumes and beans. Type A came about as people started planting and harvesting their own food so the diet includes a larger amount of grains and vegetables and less meat. As Type O and A peoples migrated to new environments, blood Type B appeared and the diet that works best B’s is a balance of meat, grains, vegetables and dairy. Blood Type AB is the most recent type and is the result of the intermingling of A and B blood types. The AB diet includes significant amounts of seafood and cultured dairy.
According to Dr. D’Adamo, the best foods for each type are as follows:
Type O: meat, fish, vegetables, fruits
Type A: vegetables, tofu, seafood, grains, beans, legumes, fruit
Type B: meat (no chicken), dairy, grains, beans, legumes, vegetables, fruit
Type AB: meat, seafood, dairy, tofu, beans, legumes, grains, vegetables, fruit
