Blood Groups and Individualization

So, as there are different types of blood groups, it is assumed that there is a link between personality traits, dietary requirement, and pattern, and diseases that people are prone to, with respect to their blood groups.
But there is no strong evidence that supports these theories of blood group type and related factors.
Therefore not all, but few people might get better fitness by following some dietary guidelines about foods to include/ exclude depending on the blood group type.
The theory was introduced in the year 1996, by naturopathic physician Dr. Peter D’Adamo. He is also the author of the book “Eat right for your type”.

Blood Groups and Food types

According to Dr. Peter D’Adamo’s :

blood groups and food types

These were few recommendations by Dr. Peter D’Adamo’s but unfortunately, there is no strong evidence that supports the theory that by following this diet pattern a person can lose excess weight or can avoid diseases.
Although, including a good amount of protein sources, complex carbohydrates and vegetable, fruit intake is any way helpful to maintain fitness!

Another dimension to the concept of correlation of blood group and dietary pattern could be understanding blood groups that are considered as “at risk” for certain diseases.

A few studies (published in were conducted to understand this correlation and diseases.


  • Hypertension:- High blood pressure disorder is seen more in people with blood group type “B”; while “AB” blood group individuals are having the lowest rate of this problem.
  • Hyperlipidemia:- blood groups “A” & “B” are prone to increased levels of total cholesterol, LDL cholesterol & triglycerides; while “AB” is protected from this disorder.
  • Diabetes mellitus:- blood group “O” has the lowest risk of developing type 2 DM; while blood group “B” shows the highest risk, followed by “AB” blood group type.

With this information, we know that its better to plan a diet in such a way that it prevents or reduces the risk of diseases for respective blood groups.

Here are few tips for all the individuals irrespective of the blood groups:-

  • Avoid smoking, alcohol, any other harmful addictions.
  •  Avoid junk food, packed readymade foods, prefer natural foods!
  •  Try to take a healthy balanced diet which includes good sources from all food groups.
  •  Stick to traditional recipes.
