For decades, the medical professionals believed that blood groups served only allow transfusions in optimal conditions of compatibility for each individual. However, a new theory, embryonic, suggesting that the type of blood that flows in our veins protects us from certain diseases and predisposes us to contract in others. Some even rely on a combination of food and blood to strengthen their immune system.

Four blood groups

It is well known, there are four blood groups, A, B, AB and O, all determined by the genes inherited from our parents and present in red blood cells. These groups are subdivided into two rhesus positive and negative, as determined by the presence of antigens (D, C, E, c, e) in the same red blood cells. Thus, a carrier antigen type D will be positive while others are negative. On the planet, the group O positive is the largest, with 38% of all human beings. For the Indian population of Peru, the rate rises to 100%. And, contrary to popular belief, the type O negative is the rarest of the globe. It flows in the veins of 7% of individuals while type AB negative includes only 1% of 7 billion people living on earth.

Blood and health

Recent research still in its infancy, remember, argue that blood plays a role in the health of a particular individual by protecting certain diseases.

Heart attack : Thus, the presence of the gene Adamts7 blood groups A, B and AB increases the risk of suffering a heart attack. However, in people with type O? the largest group studied? this risk is not higher. This finding may facilitate the development of new therapies based on the characteristics of the group O, to treat people who are at risk of having a heart attack.

Tropical diseases, ulcers and obesity : type O people are less likely to contract diseases called “tropical” as malaria. However, they are more vulnerable to cholera and stomach ulcers. These gentlemen are also more prone to obesity, especially if they are exposed to pollution.

Fertility : In women, the eggs are of lower quality if they are group O is the most widespread in the world. This is just the opposite in women A group whose eggs are more resistant. But the results did not confirm this theory beyond doubt.

Ovarian cancer : As the research has been conducted mainly in group O individuals, the available data on other groups, are less developed. However, researchers have noted a higher incidence of developing ovarian cancer in women type AB and B, while the risk of Precambrian (a condition that affects some women during pregnancy) is two or three times higher in the ladies group AB.

Pancreatic Cancer : The incidence of pancreatic cancer is also higher among all people groups AB and B.

Genes of different blood types could therefore affect certain diseases or conditions. The modest sampling, as well as preliminary findings not supported by further studies, however, are widely disputed in the scientific community.
