The Blood Diamond

All of us make sure to remember our blood groups by heart. But do we really know all the details of our blood groups?

There is more to our blood groups than just the tiny details we know about them. Our blood groups can actually determine a lot of interesting things.

From risk levels of different diseases to choosing our diet plans, our blood groups can affect many things. So, are you curious to know what your blood type means?

If you want to learn more about your blood type, this is the perfect place for you. So, here are some really interesting facts about different blood types.

There is no substitute to Blood:

Human Blood can be replaced by only Human Blood only and that too to same Blood Group or from any Blood Group provided the person accepting Blood has AB+ Blood Group which is the Universal Recipient.

Blood is Red Colour thick liquid which contains billions of Red and White Blood Cells & Platelets & Plasma.

Red Blood Cell are known as Oxygen Carries to various tissues and organs of the Body whereas White Blood Cells fights infection.

Platelets are used to clot the Blood else we will never heal from an injury. A normal human body can have anywhere between 1,50,000 to 4,50,000 Blood Platelets.

Plasma is yellow in colour when separated from the Blood. Its main function is to cary proteins and nutrients to parts of the body wherever it is required.

An Adult can have anywhere from 4.6 to 5.7 litres of Blood. That would be typically 7-8% of the of Adult Human Body Weight considering the Weight to be 80 Kgs whereas a new born baby has just 1 cup of Blood in her/his body.

Four main groups of blood:

There are actually four main blood groups- A, B, AB, and O. And these groups can further be divided by seeing whether they are RhD positive or RhD negative. Thus, there are eight different types of blood groups.

They are- A positive, A negative, B positive, B negative, AB positive, AB negative, O positive, and O negative. Now can you identify which group you belong to?

A+, A- and B- are found in just 10% of the overall human population.

Negative blood types are not really common:

Positive blood groups are more common than negative blood groups.

Many surveys and statistics show that the number of people with positive blood groups is more than people with negative blood groups.

The discovery of blood groups:

In the early part of the 1900s, blood groups were first discovered.

An Australian scientist named Karl Landsteiner was the first person to discover the four distinct blood groups.

He also won a Nobel Prize for Physiology or Medicine. Thus, thanks to him, all of us know our blood groups now.

The universal donor:

The blood group O- is the ‘universal donor.’ It is also one of the oddest forms of blood groups. Since the blood type O- is Rh-negative, it can be given to both people of positive and negative blood groups. People with O- blood type can donate blood to anyone.

This Blood group is therefore always in high demand because it is found in just 6% of the overall human population.

The universal receiver:

Since we talked about the ‘universal donor,’ the next topic is obviously of the ‘universal receiver.’

People with AB+ blood type can receive blood from anyone.

As the blood group AB contains both the A and B antigens, it can receive blood from anyone. So, contemplate yourself fortunate if you have the blood group AB+.

Is it true that your blood groups determine your personality trait?

Well, the Japanese actually believe that your blood group tells a lot about your personality. Japanese believe that our blood groups influence our behavior and traits.

From our weaknesses to our strengths, our blood types determine everything.

According to this belief, people with group A blood are usually calm, introverted, punctual, and polite; people with group B blood, on the other hand, are practical, creative, and ambitious.

Whereas people with group O blood are generally energetic, straightforward, extroverts, and confident. And people with blood type AB have a mixture of both blood type A and B personality traits.

So do you think the personality traits of your blood group matches with you? However, this theory is still debatable.

Blood group B has a lot of friendly bacteria:

Doctors believe that blood type B has almost fifty thousand more friendly bacteria than blood type A and blood type O.

Does your blood type determine your diet?


At least to some extent, they do. Dieticians and nutritionists believe that there are also blood type-based diets. And these can be extremely healthy to follow.

It is believed that people with blood type O should eat seafood and avoid dairy products. Whereas people with blood type B should eat more green vegetables and fruits. And people with blood type A should eat more berries, avocados, and broccoli.

You could be among the 1%?

If you have type AB Negative blood, you are among the just 1% of all people. It is an extremely rare blood group.

Have you ever thought that your blood type has something to do with it if you often feel stressed?

All of us go through stressful situations in life. And it is absolutely normal to be stressed in certain situations. But do you know that your blood type plays an important role in determining your stress factor?

Doctors say that people with blood type A have higher cortisol levels than other blood groups. This means they react more in stressful situations. Whereas people with blood type B have an average stress level.

And people with blood type O have the lowest amount of cortisol in their blood.

Blood Type O has lower risks of blood clotting:

People with Blood Type O are less likely to suffer from blood clots.

Doctors say that blood type O has less quantity of the proteins which help to solidify the blood. Thus, this is why people with blood type O have less chance of suffering from blood clotting.

Type AB blood is at risk of cognitive problems:

Blood Type AB is definitely the least common type of blood group.

Several types of research prove that people with blood type AB suffer more from mental health issues. In fact, this could also lead to dementia in old age.

Our blood groups are related to our parents:

Just like we inherit many features from our parents, blood type is also something we get from our parents.

People with negative blood group have more allergies:

People who have negative blood groups are more likely to have allergies. Researches prove that negative blood groups have more skin allergies.

Most of the Latino-American people are O+:

Several types of research prove that the majority of the Latino-American population have blood type O+.

According to the American Red Cross, at least 53% of the Latino American population have the blood type O+.

A+ blood type is the most common:

This is actually the most common blood group. In fact, thirty-four of every hundred people have blood type A+.

Blood types influence our intestinal bacteria:

Now, this is surely something we never thought about. But the proportion and type of our intestinal bacterias indeed depend on our blood types.

We hope that this helped you to know a lot more interesting factors about not just your blood type but also of others. Most of these facts are scientifically proven, and some of them are still debatable. But anyway, it is still good to know more about our body and how our blood types affect us.
