Many people think that acne is a natural result of being a teenager. Yet the teenagers in many parts of the world are remarkably free of acne. The low rate of acne in those populations is not due to their genes. It is due to their low-fat, heavily plant-based diet. When people from those countries grow up in the United States, they generally eat a typical American diet which is rich in fat and animal-source foods. As a result, they too tend to get acne in their teenage years.
The rich, fatty, American-style diet increases your risk of acne. It supplies a lot of fat, which can make your skin oily. It also contains lots of animal-source foods, which can lead to an overload of two types of hormones: male sex hormones (androgens) and a growth hormone called insulin-like growth factor 1 (IGF-1).

In 1996, a man named “Dr.” Peter J. D’Adamo published Eat Right For Your Type. This book promoted the “blood type diet.” It claimed that your diet should be based on your ABO blood type (type A, B, AB, or O). The ABO system of blood typing is important in blood transfusion. Getting a transfusion of the wrong type of blood can kill you. However, there is no scientific evidence that your blood type has anything to do with how your body reacts to food. People of any blood type thrive on a low-fat, plant-based diet.
The things that D’Adamo says about the natural history of the different blood types are wrong. So are the things he says about the effects of blood type on the body. Worst of all, D’Adamo gives particularly bad dietary advice to the people with the most common blood type. I suspect that his book has been so popular because he has been telling a lot of people exactly what they want to hear. He has been telling the people with the most common blood type that they need to eat a lot of fatty meat.
