Most Common Blood Type

A blood type or a blood group is a classification of blood according to their presence and absence of antibodies and inherited antigenic substances.

It depends on the type of antigens present above the surface of the red blood cell. Some of these antigens depending on the system of the blood group are proteins, carbohydrates, and glycoproteins.

Red blood cells, white blood cells, plasma, and platelets are the main components of blood. Each of them has its function and is equal. Antigens are very much important for determining your blood type.

Blood type can be negative or positive depending on the RH factor D antigen, lack or presence of other proteins. You inherited your blood type from your biological parents. But sometimes due to various possible combinations, you might not get your blood types as same as your parents. You cannot change your blood type. But in some cases, like bone marrow transplant or getting a specific kind of cancer or infection may change your blood type.

Type O is the Most Common Blood Type and O negative blood is a universal blood group required for emergency blood transfusions and immunodeficient infants. O negative blood group is compatible with any blood type. Type O people have characteristics like confidence, determination, resilience, and intuition. Sometimes they can be self-centered and unstable.

38% of people have an O-positive blood type. People with O blood type are more prone to several infectious bacteria and viruses. Some of these include plague, cholera, mumps, and tuberculosis. They have lower risks of getting coronary heart disease compared to people who have A, B, and AB blood types. There is a term known as “blood-type diet”.

A+ blood type can easily receive the blood types like A positive and negative, O positive and negative. 

Other Blood Types And Their Characteristics

B + is a rare blood type with high potency. Only 8% of the population has B + blood. B + blood donors have two options for determining their ability to donate blood. This blood type is more prone to autoimmune diseases. Some of these are diabetes (both type 1 and type 2). B+ is a very much important blood group as it helps in treating people with sickle cell disease and thalassemia who need regular transfusions.

B- blood type:

Less than 2 % of the population have B- blood type. It is not the most common blood type. People with B- blood type can give blood to both B and AB patients. They can only receive blood from B- donors or O- donors. Some of the foods you can eat with this blood type are protein like meats like mutton, venison, goat, lamb, and rabbit. You can also have dairy products like cottage cheese, yogurt, mozzarella, and beans. Type B- blood group may avoid all wheat, corn, barley, rye, and buckwheat. 

AB blood type:

AB blood type is one of the rarest blood types. The AB blood type is the “universal receptor” because patients with AB infection can acquire red blood cells of all blood types. They are generally emotional and sensitive and easily become lost in thoughts. They can sometimes be shy like A-type and sometimes be outrageous like B-type. Those with AB blood type should eat milk, tofu, lamb, fish, grains, fruits, and vegetables. For weight loss, tofu, seafood, green vegetables, and kelp are best but avoid chicken, corn, buckwheat, and kidney beans.

Some of the good personality traits are attractive, collected, cool, dreamy, caring, reasoning, honest, adaptable, and creative. They have both A and B antigens at the surface of the red blood cells. Only 3% of the U.S> population have AB+ blood type. It is not the most common blood type, but very much rare. 

Which blood type lives the longest?

People with blood type Olives a healthy life and have chances of living longer than other people. It is not always necessary that an O+ blood type person will live longer.
