Diet for the 4th blood group: the essence
According to the author of a book about blood groups and diets for them, Peter d'Adamo, people with the fourth blood group can safely consume those products that are intended for representatives of the 3rd (type A) and 2nd (type B) blood groups.
This is explained by the fact that the 4th blood group is a mixture of these two. That is why the fourth blood group is designated as IV (AB).

What is especially useful for representatives of the 4th blood group?
- Greens and salads: cucumbers, lettuce, cabbage, celery, parsley, dill

- Dairy and fermented milk dishes (kefirs, sour cream, yogurts, ryazhenka, zakvaska, maslyanka, fresh milk, cottage cheese). But there is a nuance: to prevent obesity, it is better not to drink too fatty milk, not to eat fatty sour cream or cottage cheese.

Prohibited foods for blood group 4
Those who have the rarest blood group – the fourth – are prone to low acidity of gastric juice. Therefore, it can be safely increased by eating sour foods. But it is advisable to abstain from meat. Poultry and other animal meat are not recommended, except for turkey, rabbit and ram.

Why are porridges made from these grains so harmful for people with blood group 4? Since the body accepts them reluctantly, buckwheat, corn and high-calorie baked goods can disrupt the pancreas and lead to gastrointestinal diseases.
Even if you feel good when consuming these prohibited products, you are not insured against the fact that poorly digestible products will simply be deposited as fat on your sides and waist.
Why are legumes not recommended? They are also poorly digested and can slow down the body's metabolism. This also leads to obesity and related diseases.
