Since 1997, when the bestseller “Eat right for your type” by naturopath Peter d’Adam was published for the first time, the “blood group diet” has often been talked about. of him, especially in some Hollywood actresses. The book has been translated into 50 languages around the world and has sold more than 5 million copies.
To see if this idea of a blood-group-specific diet was valid, researchers at the University of Toronto followed 1,455 young adults and had them take blood tests to determine both their group and their possible metabolic risks. According to the author of this diet, foods react differently in our body depending on our blood type. Some of them should therefore be avoided, depending on whether one is from group A, group B or group 0, to avoid developing certain diseases.
“The idea seemed attractive to us, but we found no evidence to support the theory of the blood group diet,” says Dr Ahmed El-Sohemy, lead author of this study. “How a person responds to any of these diets has nothing to do with their blood type. It has everything to do with their ability to follow a vegetarian diet or a low-carb diet,” he adds. .
According to the rules of this diet, people with blood type A should eat mainly fruits and vegetables. While people in group 0 should focus on protein and reduce dairy products. Those in group B, finally, must give up cereals and prefer green vegetables and low-fat dairy products.
