Blood group diet – how it works

The blood group diet is based on the thesis that people tolerate certain foods better than others because of their blood group. The idea behind it: By avoiding certain foods that are incompatible with your blood type, you should lose pounds and avoid or alleviate diseases. Read here whether this actually works and what advantages and disadvantages the blood group diet has!

What is the blood group diet?

The concept of the blood type diet came from the American naturopath Peter J. D’Adamo. It assumes that people, depending on their blood group, tolerate certain foods either particularly well or poorly. The reason for the different digestibility should be food proteins, so-called lectins, which react with components in the blood.

D’Adamos believes that blood types evolved at different times throughout human history, with different food types available. According to the credo of the blood group diet, those who eat according to their characteristics relieve their digestive system and lose weight. First and foremost, however, this form of nutrition should protect against numerous diseases or even be able to cure them.

The Categories of the Blood Type Diet

Different characteristics are attributed to the different blood groups:

blood group 0

Type O blood, so the theory goes, first evolved among hunters around 40,000 years ago, when humans ate mostly meat.

blood group A

Blood group A allegedly first appeared among people who had settled down and lived mainly on plant-based food.

blood group B

Blood group B is said to have only developed at a time when people mainly ate milk products and eggs together with vegetables.

Blood group AB

Blood type AB is the rarest. According to the advocates of the blood group diet, it arose after humans became omnivores who tolerated all foods well.

This is how the blood type diet works

To address the specifics of each blood type in terms of immune system and digestion, the blood type diet specifies foods that should be prioritized and those that are forbidden. For example, a person with blood group 0 should mainly eat meat and fish: Plants, on the other hand, are considered the most tolerable food for blood group A.

A brief overview of the different types and recommendations:

  • Blood group diet 0 (the hunter): high in protein, that is: meat, fish, vegetables, fruit, limited cereals, beans (except kidney beans), legumes
  • Blood Type A (The Farmer) Diet: Vegetarian, e.g. vegetables, fruit, tofu, seafood, grains, beans, legumes
  • Blood group diet B (the nomad): balanced, meat, dairy products, grains, vegetables, fruit
  • Blood group diet AB (the enigmatic one): Mixed foods, meat, fish, dairy products, tofu, beans, legumes, grains, vegetables, fruit

That brings the blood type diet

Losing weight is possible with this form of nutrition, since the choice of food is limited and you have to deal intensively with your diet. The fact that fruit and vegetables are on the plan for all four blood groups is also positive.

Risks of the blood group diet

There is no scientific evidence for the effectiveness of the blood type diet. A study published in 2014 by a research team from the University of Toronto even rejects the theory of this form of nutrition. There is no evidence that the blood group is related to the tolerance of certain foods.

In addition, scientists believe that blood types evolved a long time ago. For example, there are different blood groups in monkeys. This means that the theoretical background of the blood type diet is based on false assumptions.

The nutrient supply in the blood group diet is one-sided. For example, the diet of blood group 0 provides too little dietary fiber and carbohydrates . The tables for food selection according to the concept of the blood group diet make it difficult to choose food, and the very detailed classification of food is often not comprehensible. With blood group B, for example, red and grouper are allowed, but sea bass is forbidden.

Blood group diet: conclusion

If you follow the instructions exactly, you will quickly eat too one-sidedly. The theory of the dangerous lectins and the connection between blood and food groups has not been scientifically proven. Healthy people wanting to lose weight should eat a balanced and varied diet instead of following the strict instructions of the blood type diet .
