A little over a century has already passed since the eight blood types of humanity were revealed. Since then researchers and scientists have been trying to trace the various effects of blood types and above all to answer the question – how significant is our blood in relation to who we are?
Human blood is classified into four main groups – A, B, AB and O. Each letter refers to a different type of antigen or protein, which is on the surface of the red blood cells. In addition, each blood type is classified into plus and minus so that in total we have 8 different blood types that are inherited and cannot be changed, at least not intentionally. Different blood types lead to the formation of different types of antibodies – that is, of proteins that the immune system sends to eliminate invaders. So how does it affect the different activities of the body and maybe even our personality?
diabetes mellitus
The data regarding blood type and its relationship to diabetes are still contradictory. Research from 2020 found Because blood type O was associated with a decreased risk of type 2 diabetes, and blood type B was associated with an increased risk. Research additional examined 750 participants and found that the risk of developing type 2 diabetes was higher in blood type A than in any other blood type. On the other hand, a large study involving tens of thousands of women showed that women with type O blood have a lower risk of type 2 diabetes, while types A and B are at higher risk.
Blood clots and stroke
People with blood types A and B are at higher risk of developing blood clots than people who have type O blood, according to a 2020 study that looked at more than 400,000 people. The data showed that types A and B are 50% more likely to develop blood clots in the legs, and 47% more likely to develop a pulmonary embolism.
Another interesting statistic the researchers found is that compared to people with type O blood, those with type A or B had an 8% higher risk of heart attack and a 10% increased risk of heart failure. Blood type may also affect the risk of stroke. Research who reviewed dozens of studies on the subject found that people with type A had a 16% higher risk of having a stroke than people with other blood types, and those with type O had a low risk.
Diet according to blood type – is there such a thing?
Somewhere in 1996, a naturopath named Peter D’Adamo published a book called “Eat right according to your blood type.” According to him, the blood type is the most important factor in determining a diet adapted to the types of foods that were common during the time in history when the blood type developed.
As of today, there is no research that supports that a blood type diet is indeed effective for weight loss. Research that traced all the published data on the subject found that blood type had no effect on body weight, body fat percentage and body fat concentrations among people who adopted the method. Here are the types of foods you should eat according to your blood type:
People with type O blood should choose high protein foods and eat a lot of meat, vegetables, fish and fruits but limit grains, beans and legumes. Avoid wheat, corn and dairy products.
People with type A blood should choose fruits, vegetables, tofu, seafood, turkey and whole grains but avoid meat. Milk, wheat, corn and beans should be avoided.
Those with type B blood should choose a varied diet that includes meat, fruits, dairy products, seafood and grains. Chicken, corn, peanuts and wheat should be avoided.
People with type AB blood should eat dairy products, tofu, lamb, fish, grains, fruits and vegetables. Avoid chicken, corn, buckwheat and beans.
Memory and blood type
Staff researchers followed the cognitive function of more than 30,000 people over a period of several years. At the end of the study period, significant cognitive decline developed in 495 people. The researchers found that one particular blood type demonstrated a higher risk of cognitive decline: blood type AB. They had an 82% higher risk of suffering from memory and language difficulties alongside symptoms that could also signal the onset of dementia.
