Although the blood group diet caused a lot of talk about them, you will imagine that it has no scientific basis. On the other hand, there are very solid studies that defend that being type A, B, AB or O influences the predisposition to suffer from Alzheimer's or heart disease. Understanding the diseases or problems associated with each blood group can help us modify our routines and avoid habits that are not conducive to our health.
Group AB: Memory
According to a study published in the journal Neurology of the American Academy of Neurology, people with type AB blood have up to an 82% higher risk of suffering from memory problems and cognitive impairment leading to dementia. In contrast, according to a study conducted at the University of Sheffield (United Kingdom), people with blood group O have more gray matter in the brain than any other group, so they are more protected against cognitive decline. What can you do? A good habit you should follow to protect your memoryis to eat a balanced diet. The Mediterranean diet has been associated with a lower risk of developing Alzheimer's. Polyphenols, present in foods such as fish, fruits and vegetables, olive oil, coffee, and red wine, are believed to be responsible for this protective effect.
Group A: More stressed
Some research has studied the relationship between blood type and stress response. The results were quite explicit: the predisposition to suffer stress is associated with the blood group. Specifically, those who belong to group A may feel more stressed. They appear to have elevated levels of cortisol, the hormone that causes stress and anxiety.

Group B: Cardiac risk
If you are group B, you could have an 11% higher risk of suffering from heart disease, according to Harvard University (USA).

On the other hand, your intestinal flora will be more protected, since you will have more friendly bacteria than the rest of the groups.
Group O: Mosquitoes will bite you more
If you are type O, you will be more protected against cognitive decline, but mosquitoes are likely to bother you more than usual. A study published in the Journal of Medical Entomology has shown that people with blood group O suffer twice as many mosquito bites as other blood types. But it was not going to be bad: if you have this group you will be more protected against the most dangerous forms of malaria, since the proteins of this infection do not bind to the blood cells of this group.
