Blood type diet

Okay so lets start with the blood type. I don’t actually know why we have different blood types and how they came to be!

If you know why please tell me. However, I found an article from the BBC explaining some of the history and also problems of blood type.


I do know there are 4 main types and that is very important for blood transfusions.

It turns out that the blood type has something to do with antigens in the blood. Type A antigen has it’s own and so does B but blood type AB has both types of antigens and O has neither A or B antigens. So giving type A blood to a person with Type O is bad news as the antigens will attack the immune system.

Anyway, enough about blood types, the only thing i’m really interested in blood type is its importance to food. Here is an article explaining the blood type diet.


‘The Blood Type Diet was created by naturopath Peter J. D’Adamo. The following information is from the article above (

Peter J. D’Adamo says::

Type O blood: The diet for type 0 blood should be high-protein diet. You want to concentrate on eating lean meat, fish, poultry and vegetables, and not have huge quantity of grains, beans. Also try and avoid dairy but you will need some calcium. Goats cheese is a good substitute. People with type O do sometimes have stomach aches.’

Type A blood: Should eat a diet mainly with fruits and vegetables, should try to avoid meat. Type A blood diet has a focus on beans and legumes, and whole grains. D’Adamo says people with type A blood have a sensitive immune system so stick to fresh organic food.’

Type B blood: Should not eat wheat, corn, lentils, tomatoes, peanuts, and sesame seeds. D’Adamo says to focus on green vegetables, eggs, certain meats but not chicken, and only low-fat dairy.’

Type AB blood: Need a balanced diet that is easily digestible because AB blood can have low stomach acids. Foods that are really good include tofu, seafood, dairy, and green vegetables. You should try to avoid caffeine, alcohol, smoked or cured meats.’

So, my thoughts on the excerpt copied from is that if you know what blood type you are why not buy foods that are suited to your blood type.

Create a balanced shopping list and try and stock the foods that are great for your body. It makes sense as some people are lactose intolerant, or allergic to certain foods and some people get migraines with dairy or wheat.

There are also a whole list of superfoods- if you were driving a petrol car you wouldn’t feed it diesel!!

Peter J. D’Adamo even goes on further to suggest certain activity levels and activities that are better suited for your blood type- have a read of article in hyperlink..
