The Blood Type Diet
could be a helpful shortcut!
Is the Blood Type Diet for you? Dr. Peter J. D’Adamo believes that each of the four blood types has a different ideal diet which can sustain health, achieve perfect weight, and lengthen lifespan.
How to Eat for Your Blood Type
In Eat Right For Your Blood Type, D’Adamo explains the science behind his theories, and he lays out pracitcal guidelines:
- ▸ the food you eat contains proteins called lectins.
- ▸ these lectins are incompatible with some blood types, causing your blood to reject them and agglutinate the blood cells in that area.

Can Eating for Your Blood Type Help You Lose Fat and Get Stronger?
Dr. D’Adamo tested different food groups with each blood type to see what causes the agglutination. By avoiding these bad foods and eating what’s beneficial to our blood, D’Adamo believes we will live healthier, longer lives. D’Adamo wrote the book about the Blood Type Diet so that if you wanted to experiment with improving your health and energy, you could learn how to eat for your blood type to see if it helps:
Type O in the Blood Type Diet
Blood Type O is the oldest of humanity’s bloodline. Because of this it still benefits from the diet of early man and does not do well with newer man-made foods (like those made from wheat).
This blood type benefits from a high-protein diet that enjoys lean meats and vigorous exercise like swimming.

Beneficial foods for Blood Type O include:
- fish
- fruits
- vegetables
Foods Type-O’s can avoid:
- corn
- kidney beans
- cabbage
- wheat
Type A in the Blood Type Diet
Blood Type A stems from agricultural society. It’s believed to have developed when humans learned to farm for their food and started building villages, towns, and (eventually) cities. Because of this, a Type A does well on a diet of vegetables. It’s a mostly vegetarian diet that enjoys beans and grains, as well as seafood. Also, Type A does best with calming exercise like yoga or tai-chi.
Beneficial Foods for A’s:
- beans
- fruit
- grains

Foods to avoid:
- dairy

What Blood Type Are You?
Before you can see if the Blood Type Diet might be helpful to you, you need to know what your blood type is! Years ago, after hearing about these diets I ordered an at-home blood test online (for $10 dollars) from the D’Adamo website.
The kit came with simple instructions and even though I can be a bit squeamish about blood, it was a surprisingly easy process. You put four drops of blood on four different chemical patches to see which ones react. You then compare which ones reacted (or not) with the diagram to see what blood type you are.
This can also be quite suspenseful, although it a positive step towards increased health I was also dreading finding out what food I should not eat anymore. Will it be wheat? corn? red meat? chicken? It was like a tense moment from a game show.
After learning my type, I began incorporating the principles from the book. I gained muscle and lost fat fairly quickly. My energy went up. The whites of my eyes got whiter.
I’m not a scientist, so I can’t verify the principles of the Blood Type Diet or know if it will be good for you (ask your own doctor, nutritionist or naturopath), but for me personally, it seems to have made a positive difference in my life. When I discovered, for example, that most of my carbs needed to come from vegetables, especially the dark leafy green kind, I bought an excellent blender and began making green smoothies daily. This one lifestyle habit has transformed my life and made me much stronger and more fit!
