The book “Nutrition by genotype,” by bestselling author Peter D’Adamo, popularized the thesis according to which each of the four blood types must use specific diet in order to detect which food causes intolerance.

It has already long been debated, and many well-known nutritionists have rejected this kind of testing, until it was recently finally dismissed as a possibility with a study that completely denies it. In a sample of 1,455 respondents this study found no evidence by which it could be concluded that the blood type diet is in any way connected with intolerance.
