Diet on blood groups
The blood group diet encourages people to eat certain foods and to avoid others depending on the blood group - A, B, AB or O.
The one who developed the blood group diet, Dr. Peter J. D'Adamo, believes that blood groups affect the digestive system.
Moreover, the doctor believes that the blood groups also determine the predisposition to certain diseases and that the physical exercises must also be differentiated according to the blood groups.
Critics of this diet say that the scientific evidence on which Dr. D'Adamo relies on the regime's development is lacking.
The diet may be suitable for those who do not want to count calories or measure portions, but it can be difficult for some because it has very strict rules about what you can eat.
What you can eat
If you have blood group O (considered the oldest blood group) your digestive tract has remnants of ancient times. Your metabolism will benefit in this case if you eat lean chicken or fish. You are not allowed to eat cereals, flour, vegetables or grains and you need to exercise intensely.
Those with blood type A (from "agrarian") are advised to keep vegetarian diets, because they inherit the blood of people who are quieter and less inclined to war and fighting. The diet is based on soy proteins, grains and organic vegetables and encourages less intense physical exercise.
Blood group B corresponds to nomads and people who generally have a tolerant digestive system and can enjoy dairy products with low fat and meat content, but should avoid cereals and corn, among others. If you have blood group B, exercise should be moderate.
Those with blood group AB, considered to be the most "modern", have a sensitive digestive tract and should avoid chicken, beef and pork, but can eat seafood, tofu and dairy. The recommended fitness regime is one with relaxing exercises.
How it works
D'Adamo rejects the idea that a diet can be universally valid. With the four distinct blood groups he creates four diets specific to each type.
The importance of nutrition adapted to the blood group is vital, according to the doctor. If you do not eat according to your blood group, you may have problems with bloating, slow metabolism and even serious diseases, such as cancer.
All foods can be categorized according to three aspects:
The beneficial foods behave like the medicines for your body, the neutral ones as simply food, and the ones to be avoided are like a poison for the body, according to D'Adamo.
What the experts say
Experts are very upset when it comes to this diet. Although the diet does not contain necessarily harmful tips (for example, D'Adamo does not say to avoid fruits or vegetables), it is not based on scientific evidence.
The specialists generally reject the idea that there is some connection between the blood group and specific diseases or regimens. They also stressed that they would not recommend anyone's diet because it may, in some cases, cause nutrient deficiency.
