Type B diet
For people with type B blood, their diet should include green leafy vegetables, eggs, and low-fat milk. They should avoid food that contains chicken, corn, soy, and lentil beans as these are said to contain lectin that can bind to the antigens on B blood.
Type AB diet
Because this blood type has both the A and B antigens, the diet is a mixture of the type A and type B diets. People with this blood type should avoid chicken, corn, bananas, fava beans, smoked meat, caffeine, and alcohol. They are encouraged to eat seafood, green leafy vegetables, tofu, and dairy.
Type O diet
Type O blood is the most common blood type in the world and has neither A or B antigens. It is said that type O blood is sensitive to the lectin that is found in grains and has more trouble digesting sugar than protein and fat. For this blood type, a high-protein diet from meat and fish is ideal. Vegetables are encouraged, but beans, peanuts, and grain-based products like rice and bread should be avoided.
Should I follow a blood type diet?
The blood type diet was originally published in a book called Eat Right 4 Your Type in the late 1990s. The diet sparked a trend in being aware of blood types, but decades later no scientific studies support that idea of a connection between blood types and diet.
All humans require macronutrients like carbohydrates, protein, and fat, as well as micronutrients like vitamins and minerals. The blood type diets avoid sources of lectin as much as possible because it can cause blood cells to clump and trigger an immune response. However, lectins are found in many foods and are hard to avoid completely. Because some of these blood type diets discourage or remove entire food groups, it is not considered balanced or healthy.
Knowing your blood type is important and can also be an interesting conversation starter. While it is true that each person’s body is unique, blood type does not seem to be a significant factor when it comes to diet. The blood type diet meal plan is not recommended by most health professionals. If you are looking to manage your weight or get healthier, it is best to speak with your doctor before starting any new diet.
