In 1996, Peter D'Adamo wrote the book 'Eat right 4 your type'.
In it, he reflects his interpretation of the blood type diet, in which they assume that, according to your blood type, you may or may not process certain foods properly in your body.


What is the blood type diet ?

The theory of blood type diet has been around for a long time.
It is based on the assumption that human blood types originated at certain moments in evolution.
In addition, it is believed that our ancestors then ate what was beneficial to them. This also created the ability to digest certain foods properly.


In addition to 'beneficial' food, according to the theory, you also have 'neutral' food and 'harmful' food. In the harmful diet, the blood cells stick together, so that the immune system no longer works properly. As a result, the risk of disease increases.
You notice, this is not a classic diet that allows you to lose weight. It's more about feeling energetic and fit, because your body gets what it needs.


Then when would those blood types have arisen ?

According to the theory, blood type O would have its origin among the hunter-gatherers.

Blood type A would have arisen in the time when agriculture found its entrance. That's why a vegetarian lifestyle is ideal for this blood type.

Blood type B would have arisen in the nomad strains. It is previously linked to dairy.

How scientifically substantiated is this theory ?

It all sounds quite plausible, but I would like these kinds of theories to be scientifically substantiated as well. And that's exactly where the shoe is pinching.


Scientists claim that human blood types (A-, A+, B-, B+, O-, O+, AB and AB+) have been around for over 20 million years. Monkeys have the same system as us.
Other animals have different blood types than humans.
