Things That Your Blood Type Reveals About You, According To Science

Blood Samples

Realizing your blood classification assists with something beyond blood bondings. Scientists have found that blood classification compares with a large group of medical issues, like fruitfulness, coronary illness, and dementia.

It’s really smart to see if you are type A, B, AB, or O.
It might decide if mosquitoes are drawn to your blood or whether you have a higher opportunity of specific malignant growths. Assuming that you’re prepared to gain proficiency with a few intriguing realities about the different blood classifications, read on.

Certain Blood Types Are In More Danger Of Dementia

In 2014, the journal Neurology found that certain blood types have a higher risk of cognitive impairment. Blood types AB was 82% more likely to have cognitive impairment that can lead to dementia. The risk is lower for blood type O.

The researchers suspect this may be related to heart disease. AB types also have a higher risk of high cholesterol, high blood pressure, and diabetes. Dr. Mary Cushman says these diseases are closely linked and that people with diabetes or stroke are more likely to develop dementia.

Blood Can Affect Your Chances Of Getting The Stomach Flu

Norovirus, better known as stomach flu, infects 200 million people every year. Surprisingly, your blood type can affect your chances of getting it. According to Science Times, norovirus must attach to H1, a type of blood antigen. If your blood does not produce the H1 antigen, you may be somewhat immune to stomach flu.

AB blood groups tend to be more sensitive to norovirus than O blood groups. However, this may vary from one person to another. The norovirus is constantly changing and immunity lasts only about six months. Even if you are less susceptible, you can still get the stomach flu from time to time.

All Non-O Bloods Risk Pancreatic Cancer

Pancreatic cancer is one of the deadliest cancers. A study in the Journal of the National Cancer Institute found that blood types A, B and AB, which are not O blood types, have a higher risk of developing pancreatic cancer.

Of these, blood groups B have a higher risk. For A, the risk is 32%, for B, 51%, and for AB, 72%. The study’s lead author, Dr. Brian Wolpin, says scientists do not yet understand what increases pancreatic cancer risk.

Some Blood Types Are More Prone To Food Allergies

Research has shown that food allergies can be influenced by blood type. A 2007 study published in the Journal of Nutritional & Environmental Medicine compared the likelihood of certain food allergies with blood type. On the whole, people with a negative blood type are more susceptible to food allergies.

According to the study, people with blood type O are more likely to react to gluten, nightshade vegetables, eggs, and dairy products. Persons with blood type AB are more sensitive to nuts, seafood, eggs, dairy products, and gluten. Of course, allergies are as genetically determined as blood types. There is no guarantee that you will get an allergy just because of your blood type.

Mosquitoes Favor Certain Types Of Blood

Some people need more bug spray than others. Research has shown that mosquitoes prefer certain blood types. In 2004, a study published in the Journal of Medical Entomology concluded that people with blood type O were most often bitten by mosquitoes. Blood type A is next.

Why do mosquitoes prefer certain blood types? According to Dr. Baumann-Blackmore, they are attracted to the chemicals in sweat. Some blood types produce more substances like ammonia and lactic acid, which mosquitoes like. If you have blood type A or O, you should not go out without bug spray.

AB Blood Clots More Often

You might be at increased risk for blood clots or bleeding, depending on your blood type. The American Heart Association reports that blood type AB has a higher risk of blood clots. The risk of deep vein thrombosis or a blood clot in the leg increases by 47%. The risk of pulmonary embolism, a blood clot near the lungs, increases by 51 percent.

AB blood contains a protein that slightly increases the risk of blood clots. Blood type O, on the other hand, is associated with a higher risk of bleeding. A Japanese study published in the journal Critical Care found that O blood had a 28 percent higher risk of bleeding.

Blood Can Affect Diabetes Risk

Many people know that diet and exercise habits influence the risk of diabetes. But blood type can also contribute, even if only to a small extent. French researchers at the Gustave Roussy Institute found that women with B-positive blood are the most likely to develop diabetes.

According to the journal Diabetologia, people with B-positive blood have a 35% increased risk of developing diabetes. This percentage increases to 10% with A blood, 17% with AB blood and 21% with B-negative blood. People with blood type O have the lowest chance of developing diabetes. Remember, however, that blood type is not a sentence for diabetes.

Type A Bloods Are More Prone To Stomach Cancer

Unfortunately, people with blood type A are more likely to develop stomach cancer. In 2012, a study published in the International Journal of Molecular Sciences found that blood type A people are susceptible to H. pylori. The pathogen causes inflammation and is one of the more prominent risk factors for stomach cancer.

Further research in BMC Cancer suggested that both blood type A and AB are susceptible to stomach cancer. The study suggested that type A genotypes are more susceptible to H. pylori than blood types O or B.

The Rarest And Most Common Blood Types

As blood groups are genetic, how common they are depends on ethnicity. However, the rarest blood group overall is AB-negative. Less than 1% of the U.S. population has an AB-negative blood type, while 4% have AB-positive blood.

Worldwide, the most common blood type is O-positive; between 37% and 53% of the population has O-positive blood, depending on the country. O-negative blood, or universal donor blood, is much rarer. People with O-negative blood make up 1% to 8% of the total population. Blood groups A and B are somewhere in the middle.

Certain Blood Types May Require Different Diets

Naturopathic physician Peter J. D’Adamo suggests that people’s diet may depend on their blood type. His theory, called the blood group diet, suggests that certain blood groups should avoid and accept different foods.

According to D’Adamo, blood type O benefits from a diet high in protein and low in grains and dairy products. Blood type A may prefer a meat-free diet, while blood type B should avoid many nuts, beans and grains. AB blood groups should focus on seafood and avoid tofu and caffeine. The downside of blood group diets is that they can be restrictive and inflexible.

People With Type O Blood Are Less Prone To Malaria

People with blood group O are more protected against severe or fatal malaria than other blood groups. In 2015, Scandinavian researchers tried to find out why. It is believed that blood type O was found in countries that eventually developed resistance to malaria, such as Nigeria.

Malaria causes a phenomenon called rosettes. Rosettes form when an infected red blood cell fuses with a healthy red blood cell. According to Nature Medicine, blood group O has antibodies that counteract rosettes. Malaria cannot infect your body as quickly if you have type O blood.

People With AB Blood Are More Likely To Lose Their Memory

AB is the rarest blood type and is present in only 4% of Americans. However, research by the American Academy of Neurology shows that AB blood types have a higher risk of memory problems. People with AB blood are 82% more likely to have cognitive problems.

AB blood also increases the risk of heart attack and stroke, which are closely linked to cognitive impairment. Factor VIII, a blood protein that ensures blood clotting, may also increase the risk of dementia. However, researchers still need more evidence to determine why AB types suffer from memory loss.

Does Blood Type Determine Your Personality?

In Japan and South Korea, many people believe that blood affects your personality, in the same way as zodiac signs. This is called the blood group personality theory. According to the scientific journal Personality and Individual Differences, research has not yet supported this theory and studies on it are called “flawed” and “contradictory”.

People with blood type A are considered to be empathetic and good listeners. People with blood type B are natural leaders and people with blood type AB are independent and rational thinkers. Type O people are practical and motivated. But that’s just an overview; the full theory is much more detailed.
