The Fad:

A person’s blood type is determined by the presence or absence of markers on the red blood cell. These markers are called antigens and are controlled by genes. There are 4 blood types: A, B, AB and O. The ‘eating for your blood type’ diet is based on the belief that our blood type shows the dietary habits of our ancestors, and that by following a certain diet for our blood type, we can reduce our risk of chronic disease.

            According to this theory, people with the blood type O are encouraged to follow a higher protein diet with less dairy and grain products; type A should follow a vegetarian diet; type B should focus on eating green vegetables, eggs, low fat dairy products and avoid chicken and pork; and type AB should include tofu, seafood, dairy and green vegetables.

The Science:

There is currently no scientific evidence that supports the Blood Type diet. Research has shown that following certain blood type diets may decrease a person’s risk of chronic disease; however, this decrease was not related to a person’s blood type but instead the types of foods they ate. Instead, we encourage people to enjoy a healthy well-balanced diet with lots of colourful vegetables and fruit, whole grains, lean meat and alternatives and lower fat milk and alternatives.
