The blood type diet is a diet that provides the correct combinations of foods based on the blood type. It is a diet promoted in Italy by Dr. Mozzi and it has already made proselytes. Let's find out what it is and if it really works.

The blood type diet was conceived and tested for the first time in the '60s by Peter D'Adamo, an American naturopath, and lately it has been relaunched in Italy by Dr. Pietro Mozzi who, in 2012, wrote a book entitled: Dr. Mozzi's diet. Blood types and food combinations, in which he draws up a list of foods that bring benefits or are harmful to the individual according to his/her blood type.

What is the blood type diet?

According to the advocates of this diet, to each blood type (A, B, AB and 0) correspond certain genetic characteristics that affect metabolism, immune system, weight, but also pathologies and predisposition to intolerances or allergies, and which determine which is the right diet to follow by matching the right food combinations. For each blood type, therefore, there are some foods that should be avoided and others that are recommended, to lose weight in a simple way, keeping the right weight longer, and to prevent diseases. Dr. Mozzi gives particular importance to the lectins, proteins that we ingest through some foods and that could create intolerances if not compatible with that particular blood type. Blood type 0 is considered the most ancestral type that needs a diet rich in proteins; blood type A is the blood type of the farmer, the most evolved one that must prefer vegetables and cereals; blood type B is also called "nomadic" and it would be more inclined to adapt then: cereals, dairy products, vegetables, meat and fish; blood type AB should follow an intermediate diet between type A and B. But let's specifically look at the foods we can eat and at those we can’t eat in more detail.
