BLOOD TYPE DIET

Writer's picture: Alyra BeaumontAlyra Beaumont

Blood, a tissue that runs through our circulatory system, is vital for life since it supplies every cell of our body with oxygen and nutrients.


Blood also picks up waste and harmful material, like carbon dioxide and removes it from the body.


Blood is composed of a liquid matrix called Plasma and suspended in the plasma are three different types of cells:

1. Red blood cells, responsible for carrying oxygen

2. White blood cells are responsible for fighting infections and diseases

3. Platelets, cell fragments responsible for blood clotting


BLOOD GROUPS

Depending on the type of antigen, A or B, present on the surface of red blood cells, our blood may belong to one of these groups:


1. A (Antigen-A is present)

2. B (Antigen-B is present)

3. AB (Both of the antigens are present)

4. O (No antigen is present)


Moreover, these blood groups can be either positive or negative depending on the presence of the Rh factor.




DOES BLOOD TYPE DETERMINE OUR DIET?


The link between diet and blood type was first initiated by Dr. Peter J. D’Adamo.

He has written my books on this topic.

According to him, links exist between blood type and certain diseases which is actually the result of the research conducted by his father, Dr. James D’Adamo, who stayed with patients for long enough and drew a conclusion that ability to determine human-to-human and disease-to-disease differences must exist through blood since it is the primary source of nourishing our body.


He started his research by determining the blood groups of his patients and observing their reactions to various diets.




He did the study for years and here are a few of his findings:


● High-calorie foods did not suit the patients having blood type A. Such foods made their condition worse.

But they responded very well to soy, tofu, and plant-based proteins. Moreover, light exercise and yoga were found to be best for body strength.

● The patients with blood group O responded well to high-calorie foods and heavy exercises, like running, were found beneficial for them.

The work was continued by Dr. Peter. According to him, our blood type determines our susceptibility to illness, which food we should eat, and what exercise we should do. He is of the view that right or wrong food choices depend on our blood type. His observations in this regard are:


● Blood type, O, AB, A, or B, is a genetic fingerprint, and characteristics related to blood type can act as a guide to how one can liver healthier, reach ideal weight, and slow the aging process.


● The significance of blood type is also linked with evolution; O is the oldest blood type, A type evolved with agrarian society, B type appeared when humans migrated into harsh and colder climates, and AB type is the modern adaptation when different populations are existing together.


● Knowing the blood type difference directs choosing an optimal diet and pinpointing the foods that may have a negative impact on health. ● A food that is harmful to one blood type is beneficial to another type.


● Common foods were tested for blood type reactions and it was deduced that Lectins that agglutinate particular cells are determined by blood type and need to be avoided.

● There are three categories regarding blood type diet:

▪ Highly beneficial food that acts as medicine

▪ Neutral Food that acts as food

▪ Avoid Food that acts as a poison


Each blood type reacts to certain food lectins that can:

▪ Cause inflammation in the lining of the digestive tract

▪ Interfere with digesting process

▪ Make food metabolism slow

▪ Disturb hormonal balance


BLOOD TYPE DIET


It is the diet determined by the blood type that aims for improved health and reduced risk of diseases. The idea of Dr. D’Adamo basically states that the physiological response of our body to what we eat depends on our blood group.


He suggests that we should eat those foods that were prevailing during the time when our particular blood type evolved and eating this way will increase overall health and reduce the risk of diseases.



He also recommends food for each blood type:


Blood type A

People with type A blood might have a sensitive immune system and a meat-free diet is good for them. They should mainly eat fruits and vegetables.


Blood type B

People with type B blood are encouraged to green vegetables, eggs, and low-fat dairy. They should not eat wheat, corn, lentils, tomatoes, peanuts, chicken, and sesame seeds.


Blood type AB

People with AB blood type have low stomach acid. They should avoid caffeine, cured meats, and alcohol. They can eat dairy, seafood, and green vegetables.


Blood type O

A high protein diet, of lean meat, vegetables, fish, and poultry, is good for blood type O.


THE CONTROVERSY OF BLOOD-TYPE DIET


The idea of a blood-type diet began about ten years ago but we still did not find enough scientific support for this in the literature.

Research studies show that our response to what we eat does not depend on blood type and there is no reason to consider the blood type while choosing food.


A theory states that the AB blood type is the original one and the three others evolved from it.


This clearly contradicts what Dr. D’Adamo proposed. Moreover, if we eat the recommended blood type diet, we will get positive results irrespective of what blood type we have.


However, there must be an explanation for some important points;


  • Why do some people begin to lose weight by eating a certain diet but others do not lose even a gram by using the same diet?

  • Why do some people, as compared to others, have better physical and mental health when they are old enough?


Moreover, every human being is unique and we see significant differences from person to person in blood group analysis. People are mostly unaware of the “blood type diet” but a significant number of people were also of the view that they can improve their mental and physical health by feeding themselves according to their blood type.


Currently, no evidence is present to validate the health benefits of blood-type diets.


Studies are required to compare the health results between the participants eating a particular blood type diet and the participants consuming a standard diet within a population having a particular blood group.


Which blood group are you?

  • 0%O+

  • 0%AB+

  • 0%A+

  • 0%B+
