Not only blood type diet

Some genetic information contained in your blood is a fundamental starting point to understand the benefits or not of certain foods; however, it is not possible to regulate a perfect food lifestyle based simply on belonging to individual blood groups. The well-known naturopath Peter D’Adamo, resuming the studies and experimentation of his father James D'Adamo, has found several confirmations that an individual with a certain blood group has an affinity for some foods rather than others. These researches and observations have been supported by already existing scientific contributions, started in the early 1900s with the Austrian Nobel Prize-winning researcher Karl Landsteiner and continued with researchers Alfredo De Castello, Adriano Sturli, Emil von Dungern, Ludwig Hirszfeld ...
Certainly, the theory of blood groups and their relationship with nutrition must be further investigated; the variables to be taken into consideration are manifold and a relative diet should not be considered a dogma from which it cannot be waived.
To think that all people of the same blood group can include the same foods in their lifestyle, does not agree with the genetic differences that distinguish humans even within the same blood group.
