We can do a lot of things for our health. We can change the diet, start exercising, but there is nothing we can do about our blood, and she determines the propensity to developing certain diseases. Blood type is determined by microscopic substance that we inherit from our parents, and who lives on the surface of red blood cells.
This substance interacts with the immune system in a way that determines the risk of certain diseases. Depending on whether we are blood type A, B, AB or O will be more or less prone to certain diseases, heart problems, cancer and some others.
AB group increases the risk of cognitive impairment
Blood type AB increases the risk of cognitive impairment, says a study published in the journal Neurology. In particular, elderly people who have blood type AB have a bigger problem about learning and remembering things on the test list, which is the standard test for establishing cognitive abilities.
Blood type AB is associated with certain clotting factors and proteins in the blood, says the co-author of the study, Dr. Mary Cushman. This may help explain why it is more likely that blood type AB have problems of thinking, but it is not yet clear why.
Blood type B has a 26 percent lower risk of gastric cancer
A bit of bad news for blood type AB. The risk of gastric cancer with this blood group rose by 26 percent than that of blood group B, or 0, according to a study in the American Journal of Epidemiology. Blood type A has a 20 percent higher risk compared to blood type B or is 0.
It is possible to blame the bacteria Helicobacter pylori. About two thirds of people are walking around with Helicobacter in the gut. People with blood group AB and A have a stronger immune response to the bacteria allowing them to have an increase the risk of gastric cancer, says Gustaf Edgren, an epidemiologist at the Karolinska University Hospital in Sweden.
The same bacteria that can cause stomach cancer in people with blood group A or AB, increases the risk of ulcer or ulcer in blood group 0. This blood type in some way modifies the immune response to the bacteria, but it is not known why. Dr. Erdgren says the modification of the immune system might explain the reaction.
Blood type 0 has a reduced risk of heart disease
People of blood group 0 have another advantage. In them is a reduced risk of heart disease by 23 percent compared with people of other blood types. So claims research from the Harvard School of Public Health. People of blood types AB and B are in great risk of developing heart disease, a study shows. The authors say that certain blood types are more prone to inflammation which may explain the relationship with heart disease.
More good news for the blood type 0. The holders of blood group 0, 37 percent are in the lower risk of cancer of the pancreas than those with other blood types, says research from the Journal of the National Cancer Institute. Scientists warn of greater presence of Helicobacter pylori with other blood groups which could explain the higher rate of pancreatic cancer among them.
Although it seems that blood type has a role in the onset of a particular disease, it is not clear whether this role is small or large. The best advice is to keep a healthy lifestyle, eat healthy, exercise and only worry about things over which you have control.
