Blood type diet

The blood type diets are fad diets advocated by several authors, the most prominent of whom is Peter J. D’Adamo. These diets are based on the concept that blood type, according to the ABO blood group system, is the most important factor in determining a healthy diet, and each author recommends a separate diet for each blood type. The consensus among dietitians, physicians, and scientists is that these diets are unsupported by scientific evidence.

The underlying hypothesis of blood type diets is that they have different types of digest lectins, and that if they eat food, they are not compatible with their blood type. On the other hand, if a person eats food that is compatible, they will be healthier. This hypothesis is, in turn, based on an assumption that each blood type represents a different evolutionary heritage. Based on the blood-type diet theory, the group is considered to be an ancestral blood group in humans. We have a vegetarian diet in this group, which is believed to have grown after the agrarian society. individuals with blood group are believed to be nominally tribes. Finally, individuals with a blood group are considered to be at least one of the group A and group B. ”

As of 2017 there is no scientific evidence to support the blood type diet hypothesis and no clinical evidence that it improves health. Peter J. D’Adamo, a naturopath, is the most prominent proponent of blood type diets. Luiz C. de Mattos and Haroldo W. Moreira point out that assertions made by proponents of blood type diets that the blood type was the first of the kind that the O gene has evolved before the A and B genes in the ABO locus; phylogenetic networks of human and non-human ABO alleles show that the gene was the first to evolve. They argue that it would be extraordinary, from the perspective of evolution, for normal genes (those for types A and B) to have evolved from abnormal genes (for type O). Yamamoto et al. further note: “Although the blood type is common in all populations around the world, There is no evidence that the gene represents the ancestral gene at the ABO locus. Nor is it reasonable to assume that a defective gene would arise spontaneously and then evolve into normal genes.
