Fauvism is a hereditary blood disease that affects approximately 100 million people worldwide, including most people in Africa, Southeast Asia, and the Mediterranean.

In Iran, it is mostly observed in the northern regions of the country.
Fauvism is caused by the deficiency of one of the enzymes of red blood cells, which, due to exposure to oxidizing substances of red blood cells, leads to their destruction and makes a person with Anemia faces severe
Beans are one of the foods that contain substances called “Vicin” and “Covicin” which are converted into “Divisin” and “Isoramil” in the digestive tract and during the chemical processes of digestion, these substances are considered strong oxidants, so As soon as they come into contact with the membrane of red blood cells in people who lack glucose phosphate and dehydrogenase enzymes, they are destroyed and destroyed, and the person gets “favism”.
Therefore, these people should avoid eating fresh and raw grains. This disease is more common in boys than in girls, but it can also happen in girls.

Anemic attacks caused by favism in children and infants are very dangerous and the child may suffer brain damage and even die. d
In fact, children with favism are 1.5 times more susceptible to jaundice than other children. If this problem is not solved in patients, favism can lead to serious problems and the person may go into a coma and even die.

Currently, one of the treatment methods being investigated for these patients is the use of vitamin E as a very strong antioxidant.
This research shows the effect of vitamin E on increasing hemoglobin after blood transfusion in acute attack of favism. Vitamin E is one of the strongest fat-soluble antioxidants, and by stabilizing and strengthening the red blood cell membrane, it has a protective effect against hemolysis.
