Blood Group and Health

Many of you may have heard of the "blood group diet", a fad among celebrities, like Demi Moore, Cheryl Cole and Elizabeth Hurley. Blood group diet followers believe that different blood groups process foods differently and that eating food compatible with your blood type will make you healthier. On the other hand , eating foods that don't agree with your blood type might lead to health problems. While there seems to be little scientific evidence to support this, there certainly seems to be a correlation between blood group types, your health and overall well-being.

Your blood group could determine your risks of cancer, cardiac diseases, stomach ulcers, infertility, malaria, cholera etc. Not just that it may also help you find out which diseases you are protected from or your least probability of contracting certain diseases.

While age is still the most important risk factor when considering fertility problems, it has been found that the link between blood groups and reproductive health of women is real. For instance, a study has found that women of type A blood group seemed to be better protected against their egg counts falling over time while blood type O were up to twice as likely to have a lower egg count and poorer egg quality, which could affect the chances of conceiving.

People with type O blood are at less risk of dying from malaria than people with other blood groups and have the least risk of heart diseases. But they are more vulnerable to cholera and stomach ulcers caused by viruses and bacteria. I may have to add here that my father's blood group is type O and he frequently suffers from stomach upsets and recently had a severe stomach ulcer issue that cleared after proper medication.

Type AB's have the highest risk of heart diseases and age-related memory loss than other blood groups. Type O's are more affected by stress, while all non-O types have greater risk of stomach and pancreatic cancer.

According to a study that involved 901 Japanese emergency care patients, blood type O is associated with high death rates in severe trauma patients. Loss of blood is the leading cause of death in patients with severe trauma.  Patients with blood type O have been shown to have lower levels of von Willebrand factor, a blood clotting agent, than those with other blood types. Lower levels of von Willebrand factor may be linked to higher levels of haemorrhage. The authors of the study suggest that a lower level of the factor is a possible explanation for the higher death rate in trauma patients with blood type O.

Due to consumption of unclean, unhygienic food while traveling or in some other circumstances, people usually get affected by food-poisoning and traveler's diarrhea. Mostly E-coli bacteria is responsible for this condition. However, researchers have found that the severity of their symptoms seemed to depend on their blood type. People with type A blood were more likely to develop severe diarrhea when infected with this specific type of E. coli than those with type O or B blood, the study authors reported. They found that E. coli releases a protein that sticks to intestinal cells in people with type A blood, but not those with type O or B blood. The protein also sticks to the E. coli, making it easier for the bacteria to infect healthy cells.

It's a fact that our blood groups do have an effect on our health and our immune response to diseases but it's not clear to what extent. So the best thing to do is to follow a healthy lifestyle. Eat right, exercise, meditate and worry less. And most important - do not obsess over something (like blood-groups), over which you have no control.
