Although as species all human beings share very physiological characteristic, we also have some differences. Among them, the four blood groups: A, B, Ab and 0 (also called O). Party of these differences, Dr. Peter J. D’A Amro describes a diet according to the type of Sanzre. Its goal without it was weight loss, but Improve health status and prevent pathologies appointments. The dietitian-nutritionist VAT Marques, Patroness of the Spanish Academy of Nutrition and Dietetics and professor at the University of Zaragoza, puts the magnifying glass on the diet of the blood group.
Origin of the diet according to the blood group
American Naturobata Peter J. D’Adamo published in 1996 the book Eat well 4 your guy, Where he listed that Foods that most agreed to his person according to his blood group. The book soon became a Better soldSelling more than 7 million copies worldwide. To date it has resulted in more than 60 languages.
D’Amo postulates that, dependent on our blood group, we are going to metabolize food differently. This, in turn, would have health repercounts at a general level. «According to this theory, our bleeding group would condition the Procurement of Digestion, Biodisitability and Use of the Nutrients and their Metabóacas Ways. Also established a predisposition to its. II, pancreatitis, skin alterations, ovarian or cancer, among others,» says Marques.
Partying that supposed relationship between food, the blood group and the prevalence of disease quotes, the naturopath advocates four different food guidelines, according to a, b, ab or 0, as fOrma of intrarging that ‘natural predisposition’ to the disease.
Tupo of blood, antigens and lectin
Sanguíno group presents different antigens. These antigens are found on the surface of the red blood cells and are responsible for the compatibility between different blood types, it is to defend, it makes a perpetition of group A can receive a counterfusion of another of the same group, but not one not one of Pureda to receive a transfusion of ootra of the same group, but not one not one of the group of the group of the Grupe of the B. A have the antigen a; Those of Group B, Antigen B; Those of the AB group, have both the antigen A and the B antigen; and those of group 0 do not have the antigen A nor the B.
D’Adamo goes further and points out that these antigens would also make differences in the different processes of digestion, and even in the microbiota (or microbiome) and in much of the metabolism. The cause would be in the LectinasUnbo of proteins presents in legumes or whole grains, enter others. Lectinas have the ability to join the antigens of the ABO system and agglutinate. «According to this theory, this situation would prosecute a minor use of the nutritious of certain alleys depends -of the texting of your blood,» explains Marques.
Fundamentals of the diet according to the blood type
The theory of D’A. Hence, according to the Blood Group of Cadada Person, it suits you more to eat as a man of the hunter caverns, or as a more proper farmer-cosequador of the Neoléco. Marques the curriculum like this:
- TUPO BLOOD 0. «Procedure of the first humans, who were hunters-gatherers. It would have taken less carbohydrates and more proteins,» he explains. The people of the group 0 mayor of tenderro ease to digest food of animal origin rich in proteins and fats, but not milk and its derivatives.
- Blood tupo a. It would arise when humans became farmers. These people tenderríes more difficulties with animal proteins, but could easily digest foods of plant origin, such as vegetables, fruits and legumes.
- Tupo blood b. Procedure of nomadic tribes, with more capacity to assimilate lórcteos and fats in general.
- Blood tupo ab. These people would have inherited dietary conditions of groups A and B, so it should be wearing a diet with more food groups, vegetables including, slime and some meats.
Food table according to the blood group
D’Adamo does not speak of prohibited foods according to your type of wranger, in the sense of establishing a total restriction. Rather, it points to which food groups would contribute to maintaining a good state of health or, on the contrary, it would favor the appearance of ailments.
| Blood group | Recommended foods | Foods advised |
| TO | Fruits, vegetables, tofu, legumes and integral cereals | Meats and lopteos |
| B | Fruits, vegetables, cereals, fish, lords, lords, meat | Chicken |
| Abundant | Green leafy vegetables, tofu Moderate consumption: meat, fish, shellfish and lópcetes |
Chicken |
| 0 | Lean meats, poultry, fish, fruits, vegetables | Grains, legumes and lords |
For making a moment, a weekly diet menu for the blood group would be majority of a vegetarian diet. In the opposite pole, the diet menu for blood group 0 would approach a low carbohydrate or carbohydrate diet.
Scientific evidence of the blood group diet
Hae few rigorous studies that support the theories of this diet. Even so – emphasizes Marques – «We are facing Healthy diet relativeOr, as the authors of the few studies available, ‘prudent diets’ or prudent diet say. These are guidelines that exclude processed and ultraprocessed foods, sugars … «. You enter words, they are diets that include healthy foods, if ben in some cases, restricted food groups from healthy, as leptumbs.
Although these prudent diets can be relatively healthy, there is no hay evidence that diet diet with these foods will improve the health status of people of a blood group in concrete. In the few studies carried out in subjects to which a diet was subjected according to its type of slang for 6 months, it was observed that the metabolomics improved in all cases. “It was seen that the blood biochemical parameters are reduced that predispose to certain diseases, such as total cholesterol, the perimeter of the tape, fasting glucose, trigly Healthy patterns ”, emphasizes Marques
That is, it follows that there were improvements because all diets contained healthy foods, but there was no difference between groups, so there is no evidence of these positive results were due to the fact that subjects a eat or stopped eating synications. «Among other things because one of the pillars of his theory, the lectinas, for example, they are lost majority with soaking or cooking,» explains Marques.
There is also no evidence of a greater or lesser digestibility according to the blood group. The expert emphasizes that «the human being is able to follow an omnivorous pattern, or» mixed diet «, according to the denomination of EFSA and FAO. All humans are physiologically trained to digest, absorb and metabolize the different foods. Thanks to this we have survived as a species.
