The next blood type to evolve was type A. As the
environmental conditions changed, humans began to
grow food rather than hunt it. The diet shifted from
predominantly meat to plant-based. As the diet
changed and the blood type A evolved, antibodies
for lectins to meat were formed. According to Dr.
D’Adamo, individuals with blood type A have anti-
bodies against many lectins found in meat and will
benefit from a largely vegetarian or plant-based diet.
The next blood type to emerge was type B. As
ancient peoples migrated and adapted to further cli-
mate change blood type B evolved. The diet included
both meats and plants as well as dairy products. Dr.
D’Adamo believes this is the reason individuals with
blood type B developed fewer antibodies against lec-
tins found in meat and grain. He also believes this is
why people with blood type B are more tolerant of
milk products than other blood types.
The final blood type to evolve was type AB. It is a
rare blood type even today with fewer than 5% of the
world’s population having type AB blood. Type AB
evolved when the A and B blood types intermingled. Dr
D’Adamo describes this blood type as a complex blood
type with many strengths and many contradictions.

Within each of the sixteen food groups, he
describes individual foods as foods that encourage
weight gain, foods that encourage weight loss, benefi-
cial foods, neutral foods, and foods to avoid. In this
way the diet is unique and individual for each blood
type. For example, chicken is considered neutral for
individuals with blood type O and blood type A and is
found on the foods to avoid list for individuals with
blood type B and blood type AB. Another example is
grains such as wheat. Dr. D’Adamo reports there are
no wheat products that are beneficial for people with
type O blood. They are to be avoided. Similarly, he
advises individuals with type B blood to avoid wheat
as well. On the other hand wheat is highly beneficial
for people with blood type A and neutral for those
with blood type AB. There are recipes and sample
menus for each blood type as well.
In addition to specific and detaileddietary guide-
lines,Eat Right for Your Blood Typealso includes
advice for each blood type concerning the impact of
stress on the body and strategies for coping with stress.
Dr. D’Adamo outlines the best supplements for
each blood type and addresses the best form of exer-
cise for individuals of each blood type.KEY TERMS
