Blood Type O Diet β€” What to Eat and What to Avoid?

A person's blood type is one of the most important pieces of information we can have about them, biologically speaking. It is from this data that we understand to whom she can donate blood and from whom she can receive it, for example.

This is because, although we are all composed of this red liquid, it is not the same for everyone. There are four blood types, which are either Rh positive or Rh negative. Thus, the blood of an individual can be: A+, A-, AB+, AB-, B+, B-, O+ or O-.



To identify your blood type, you need to take a blood test. That done, you can now unravel the universe of the blood type diet, created by Peter d'Adamo. For him, the food we eat affects our bodies in different ways, depending on the type of blood we have.

So a person with blood type O, positive or negative, must eat in a different way than someone with another blood type, in order to avoid diseases and maintain the proper functioning of the body. Next, learn more about the diet for this blood type!

Understand the influence of each type of food

The blood type diet advocated by Peter d'Adamo defines that there are three food groups for us. Beneficial foods, which prevent and cure disease, neutral foods, which are indifferent to our bodies, and harmful foods, which can cause disease.
