Blood-group affiliation
Blood-group affiliation as a genotype also tells us something about metabolism. Modern genetic research has confirmed this link.
In North America two famous naturopaths, James DŽAdamo and his son Peter have carried out research into blood groups and their relationship to biochemistry, nutrition and illness.
Although science continues to look for parallels, experience shows that the consideration of the blood groups in nutrition results in better health. Although the blood group is one important aspect in the healthy & active metabolism program, it alone is not enough for a healthy metabolism.
