He is a firm believer in the fact that blood types are crucial for our health and well-being and that certain food is harmful to one blood type but helpful to other. Also, he claims that even the manner of exercising can be closely connected to your blood type, or on the contrary, your blood type can cause you some illness.
Some experts do not agree with this method of nutrition but since his book was published, 7 million sold copies speak for themselves.
How Do Blood Type Diets Works?
D’Adamo has a theory that says that every person has his own way of responding to food, and that is closely connected to our blood type. Lectins (carbohydrate-binding proteins), in his opinion, can attach to different blood type in a different way. It can be extremely harmful for your health if certain lectins contact certain blood type.
Dr. D’Adamo thoroughly explains these changes and side-effects in his book, still, his main goal is to analyze which foods are appropriate for each blood type and in which amount should they be consumed.
The Four Basic Blood Types:
1. BLOOD TYPE A:
Twenty thousand years ago, when agriculture was developed, this blood type had the change of a lifetime. This means that blood type A should concentrate on having a vegetarian way of life- the people are also known as “the agrarians”.
People with type A blood should avoiding eating meat, and eat fruits and vegetables, beans and legumes, and whole grains. To be more precise, organic and fresh foods, because as D’Adamo explained, these people have a sensitive immune system.
2. BLOOD TYPE O:
Being one of the oldest blood types, dating since 30 000 years ago, it requires a protein-filled nutrition, unlike any of the other blood types. The people are also known as “the hunters”.
These people should focus on eating more high-protein foods, such as lean meat, poultry, fish, and vegetables, and reduce the consumption of grains, beans, and dairy products. D’Adamo recommends different supplements that will assist in cases of stomach ache, and other issues these people usually have.
3. BLOOD TYPE B:
The people commonly known as “the nomads” possess the quality to be quite adaptable to dairy products and have the most versatile digestive system of all. This blood type first appeared ten thousand years ago.
People in this group should avoid corn, wheat, buckwheat, lentils, tomatoes, peanuts, and sesame seeds. According to D’Adamo, chicken may also cause certain problems. He recommends eating green veggies, eggs, certain meats, and low-fat dairy products.
4. BLOOD TYPE AB:
Since this is the most recently developed blood type, their diet varies between Blood type B and A. Because this blood type is only a thousand years old, the people are called “the enigmas”.
Diet based on tofu, seafiid, dairy, and green veggies. D’Adamo explains that these people often struggle with stomach acid, and should avoid caffeine, alcohol, and smoked meat delicacies.
If you do not know your blood type, your medic or physician can easily determine it for you.

Organic food applies to all blood types but a nutritionist can help you expand your diet if necessary. Food groups generally are strict, so you if you are dieting you don’t have to worry about calories. Also, get informed about the positive and negative influences of your food choice. If you are dieting as a family, but have different blood types, the Atkins diet is the most recommended, because it avoids entire food groups.
Nutrition in accordance with your blood type can be fit for one person, but unsuitable for other. To get a grip of the whole concept, reading Dr. D’Adamo’s book may be very helpful. Your nutritionist or medic can also help in giving you proper advice for any change you want to make, especially if you have any medical condition.
