Blood Type Diet - Eat Right 4 Your Type
The blood type diet book, Eat Right 4 Your Type, is the result of the work of two generations of licensed naturopathic doctors (NDs). Dr. Peter D’Adamo continues the work of his father, Dr. James D’Adamo who discovered the link between blood type and diet. First published in 1996, the book is a NY Times bestseller.
Dr. Peter D’Adamo proposes that blood type is a genetic powerhouse with a primary influence on the immune system, metabolism, and digestive processes. He states different blood types have their own food preferences.
This explains why some foods work great, a super food, for some but does not work well for others. Dr. D’Adamo explains so well why some do well on Paleo diets and others thrive on vegan oriented diets. His theory is lectins are the issue. His scientific work proves different lectins have different effects for each blood type.
Blood Type Diet Profiles
Dr. D’Adamo breaks down foods for each blood type and identifies them as highly beneficial, neutral, or avoid. Highly Beneficial foods act like medicine, advancing health and protecting against illnesses. Neutral foods provide required macronutrients and caloric energy. The avoid foods act like a poison, inducing biological disorder. Consuming avoid foods increases the chance of disease. Dr. Peter D’Adamo shares stories in his book of his clients who are ill from the wrong diet then recover after adopting their blood type diet.
Here’s a summary of the major points for each blood type:
Type O
High protein: meat, fish, vegetables, fruit. Limit grain, beans and legumes.
Highly beneficial foods: kelp, seafood, red meat, kale, spinach, broccoli, olive oil
Avoid: wheat, corn, navy beans, lentils, kidney beans, and dairy
Type A
Largely vegetarian: vegetable, tofu, seafood, grains, legumes, fruit, and turkey
Highly beneficial foods: olive oil, seafood, vegetables, pineapple

Pork and pork products are an avoid food for everyone. The book is even more thorough and has much more to offer

Healing Foods = Blood Type Diet – Carroll Food Intolerances – Allergies
My ND is a Carroll Method ND and a Vitalist. I actually took my copy of Eat Right 4 Your Type book on my first visit. She totally supports this work about lectins and blood type. She even discussed with Dr. D’Adamo that the blood type diet is great but not perfect since it doesn’t identify the intolerant foods. Her best dietary advice is to eliminate your Carroll intolerant foods and follow the blood type diet. The Carroll test is not about blood reactions to lectins.
My Notes
Over a decade ago I discovered and eliminated my food intolerances. The majority of my symptoms disappeared except for three issues, occasional constipation, skin cysts, and osteopenia. Some skin cysts were inflamed, red and swollen. I did not know why. Even cutting alcohol and all reactive sugars for several years did not stop new cysts from forming. These cysts are visible in my picture below and see pics in the video below.
I was so fortunate to find my new ND, she is a Vitalist and trained in the Carroll Method. She advised to stop taking the handful of calcium and bone supplements. They were high quality supplements from the compounding pharmacy. However, I learned these supplements included several ingredients that do not improve health, i.e., magnesium stearate. She recommend a few high quality, liquid, easy to digest supplements that she did not sell. I took home cilantro from her garden to assist in detoxing. She advised to start the blood type diet. I learned my diet had included many avoid foods and not enough beneficial foods.
The O blood type diet aligns well with my food intolerances. The blood type O avoid includes my primary intolerances, dairy and wheat. The O avoid list also includes peanuts, potatoes (not sweet potato), cauliflower, corn, and soy. (Check the blood type food chart above for a complete list.) With this new knowledge of the avoid foods, I noticed avoid food reactions are less severe than eating intolerant foods. As I experimented with the type O avoid foods, I discovered I don’t digest them well, experiencing bloating and gassiness.
I added more beneficial foods. I also followed my Vitalist’s advice to practice constitutional hydrotherapy at home. After ten months of these changes, my skin finally healed and I’m not constipated. I don’t have any new osteopenia results but I can share my second test results were worse. This was after two years of heavy supplements and before strength training.
I’m so thankful to my all of my Vitalist’s advice, especially to adopt the blood type diet.

I hope you check out my Home page. I advocate for a simple, accurate food intolerance test. Easily identify foods you can’t digest with the Carroll Food Intolerance Test.
