Ideal Diet for Blood Type B

Consuming a diet that is suited to your blood type is a concept popularized by Peter J. D'Adamo, N.D., a naturopathic physician who wrote the bestselling book "Eat Right 4 Your Type". According to him, if you have a B-blood type, you should eat foods different from people with other blood types (A, O, or AB) because certain proteins called lectins from foods react with your blood. Be careful, though, when choosing a blood type B diet because there is little scientific data to support such claims.

Blood Type B and Its Characteristics

According to Dr. D'Adamo, people who have type B blood carry certain genetic potential for being flexible and able to change with varying conditions. You are able to move in either direction of the continuum, but you can be highly sensitive to factors that can make you slip out of balance. Challenges to optimum health include a higher sensitivity to lectins (a type of protein) in certain foods, tendency to produce higher levels of stress hormones, proneness to slow growth, and susceptibility to autoimmune diseases.

The primary challenges that can get in the way of optimum health for type B include a tendency to produce cortisol levels higher than normal in situations to stress, sensitivity to the B-specific lectins in certain foods, and proneness to lingering viruses. However, Dr. D'Adamo explains that a healthy blood type B individual has fewer risk factors for disease and tends to be more physically fit and mentally balanced than people of other blood types.  

He, therefore, advice people to eat right for your blood type B, which will be suitable to their following characteristics:
