Peter J. D'Adamo & the Blood Type Diet


Fascinated by the correlation between diet and blood type, in the early 2000s, Naturopath Peter J. D'Adamo published a book that quickly became a New York Time's Bestseller called Eat Right 4 Your Type. This comprehensive guide is based on the idea that your blood type reflects your internal chemistry - that it dictates how well you are able to process certain foods and substances. This phenomenon fascinates me, as in a way it is such a simple concept. So, without further delay, I've comprised some recommendations of what foods to eat and which ones to avoid based on your blood type.

O Blood-Type ~ Central Asians & Africans

May be predisposed to digestive issues, such as ulcers and thyroid disorders. Type O's usually have higher levels of stomach acid and secrete enzymes at much higher levels that help breakdown protein and fat. Unfortunately, this means that they also convert simple carbohydrates into fats and triglycerides more easily than other blood types, leading to inflammation and auto-immune diseases. Adrenaline is naturally higher for type O's as well, so they may appear more stressed as well.

What to eat: kale, collard greens, broccoli, spinach, romaine, artichokes, seaweed, turnips, sweet potatoes, pumpkin, red peppers, parsnips, parsley, onions, okra, leeks, horseradish, garlic, dandelion, chicory, plums, prunes, figs, butter, feta, mozzarella, goat cheese, soy milk, olives, flaxseed, canola oil, sesame oil, sprouted breads, amaranth, barley, rice, kamut, kasha, millet, rye, spelt, beef, lamb, mutton, veal, venison, cod, herring, mackerel, iodized salt, carbonated beverages.

A Blood-Type ~ Blackfoot Indians, Australian Aborigines, Eastern Europeans, and Scandinavian peoples

Have a potentially sensitive immune system. People with this blood type usually have lower amounts of stomach acid so they do not digest meat as well. This as well as other factors puts them at risk for diseases like cancer and diabetes.

B Blood-Type ~ Australian Aborigines & Western Europeans

More likely to be magnesium deficient, which can lead to weight gain and poor regulation of calcium, vitamin D, zinc, and potassium. Type B's also produce more cortisol than other blood types, which causes them to be more susceptible to certain autoimmune diseases  However, due to the nomadic nature of their ancestors (Mongolians, Japan, China, and India) they are typically the most adaptable of all of the blood types.

So there you have it, those are the different summaries of what is recommended based on your blood type according to the studies conducted by D'Amo, the author of Eat Right 4 Your Type. Of course everybody is going to have different sensitivities based on other individual factors, but I thought it was a really interesting concept and wanted to share. As an AB+ blood type, I found that a lot of the recommendations resonated with me, as I feel that smaller meals agree with me more and my diet is also meatless - mostly tofu and greens already. For those of you who know your blood type, I would love to hear your thoughts. Do you find that the suggested foods for your blood type agree with you already?
