Blood Type Diet

A blood type diet is a nutrition plan based around your blood type. This kind of diet became popular with the release of Peter D’Adamo’s book Eat Right 4 Your Type. The book continues to be a bestseller. D’Adamo claims that the diet will not only bring about weight loss — but can assist with allergy and infection resistance, and will achieve overall good health.

Most of the population has blood type O. Here the prescribed diet is low-carbohydrate, high in proteins (such as meat and fish), and low in dairy products. The author suggests specific foods to avoid; such as avocados, brazil nuts, and oranges. Type O should also engage in lots of exercise.

Blood Type A should avoid red meat, eat plenty of fish and vegetables, with a low dairy intake. Light exercise only.
Blood Type B should avoid chicken and bacon, eat plenty of meat and dairy, some fish, and plenty of fruit and vegetables.
Blood Type AB combines the A and B diets.

Is This Diet For Real?

The author claims that much of the recommendations are based on scientific evidence – but perhaps it is too early to make this claim. Metabolism and/or sugar/insulin sensitivity are probably key factors in deciding diet – not blood type. Two people can have very different metabolisms and have the same blood type. One could be sensitive to carbohydrates or sugar, whilst the other needs a high carbohydrate diet.


Banned Foods

Any diet containing a long list of banned foods can be difficult to follow. Eat Right 4 Your Type and the various blood type diets included encourage a predominantly meat and fish diet, while grains, potatoes, cereals, breads, pasta are not encouraged. Interestingly, certain vegetables and fruits are also banned.
