This scheme takes into account the nutritional needs of people depending on their blood type. Leading to a specific food but also a lifestyle profile, with good and bad sides.
The principle of the system of blood groups

Regime sanguinsGarder groups according to the blood, that s what this proposed scheme devised by a naturopath American James Adamo. During training in spa centers in Europe, he noticed that the spa react differently to the regime. He imagines taking into account the nutritional needs as blood type, the assumption that blood is the principal vector of nutrients. His son, also a graduate Naturopathic develops this hypothesis and is known for his book "4 blood types, 4 diets". The theory? Each blood type has a specific chemical composition and different antigens. Some foods have chemical compounds - the lectines - who, consumed by the wrong blood type, causing the formation of antibodies by antigens. These antibodies have a detrimental effect on the body. Note that it s an assumption that has no scientific basis.

Dr. D Adamo provides food therefore determined by the blood and when they would appear. For him, 4 profiles exist. The people of O blood group, only time this group of men hunter-gatherers, Group A, appeared at the time of the discovery of agriculture, those of Group B - Group found primarily among the nomadic peoples -- and those in group AB. This method aims to lose weight, but also to strengthen the body and slow the aging process. That is why the book by Peter D Adamo provides guidance on physical activity preferred supplements ... and even the lifestyle adopted by the profile.
Blood group system in practice

This regime does not occur in phases, like many others. It must be practiced throughout life to keep the profits. For each blood group, foods are classified into three groups: "beneficial", "neutral" and "avoid." The ideal? Consuming food especially beneficial, very little food and no food neutral to avoid.

People of group O should eat meat, vegetables and no dairy products or starchy foods and physical activity intensity on a regular basis.

Those in group B, must be nourished by milk, vegetables, meat, eggs but can not eat chicken, corn, peanuts and lentils. Their sports? Walking or swimming.

For Group A, a vegetarian diet of vegetables and cereals is required: lots of fruits, vegetables, grains, no meat, no beer, no dairy or beans.

Persons Group AB may involve food groups A and B: they eat tofu, green vegetables, fish, seafood, pineapple, but not red meat, or seeds.

Finally, all groups blood should remove the pork, smoked salmon, rhubarb, wheat bran, coconut, ice cream, oils, corn and peanuts, black pepper and vinegar ...

Note: FC laboratories offer ABO method, based on the theory of blood groups: a herbal medicine specifically for each blood type (plants referred drainage, anti-water, anti-fat, anti-) and adequate nutrition to the profile of each blood.
