Blood-Type Diet Not Related to Blood Type
Based on the theory that each blood type represents distinct genetic traits and ancestral dietary habits, the “blood-type diet” advocates eating according to one’s blood type to optimize health. However, the rationale and purported health claims attributed to the blood-type diet have not been validated scientifically nor rigorously. Researchers from the University of Toronto recently examined the validity of the blood-type diet, including 973 adults from the 6-month Toronto Healthy Diet Study. Their findings indicate that the health benefits of the blood-type diet (e.g. improved cardiometabolic risk factors) are
of the person’s blood type, suggesting that the blood type diet may simply represent a healthy eating pattern.
