How Your Blood Type Determines Your Diet

Have you heard of blood type diet before? Dr. Peter D’Adamo -- a naturopathic physician -- suggests that we should follow a specific diet and exercise plan based upon our blood type in his best selling 1996 book Eat Right for Your Blood Type. The underlying premise for D’Adamo’s dietary ideas is that ABO blood type is the most important issue in determining healthful diets.

D'Adamo claims that the foods we eat react chemically with our blood type. If we follow a diet designed for our blood type, our body will digest food more efficiently. We'll lose weight, have more energy, and help prevent disease. Not everyone should follow the same diet, and that blood type and our race determines tolerance to what we should and should not eat. He feels that one’s blood type may determine which diseases and illnesses we may develop.

According to the blood-type diet, there are 4 blood types:

• Type O - the oldest blood type
• Type A - agrarian
• Type B - nomadic
• Type AB - modern

Each blood type diet includes 16 food groups which are divided into three categories:

• Highly beneficial
• Neutral
• Avoid

Here's what D'Adamo recommends for each type:

• Type O blood: A high-protein diet heavy on lean meat, poultry, fish, and vegetables, and light on grains, beans, and dairy. D'Adamo also recommends various supplements to help with tummy troubles and other issues he says people with type O tend to have.
• Type A blood: A meat-free diet based on fruits and vegetables, beans and legumes, and whole grains -- ideally, organic and fresh, because D'Adamo says people with type A blood have a sensitive immune system.
• Type B blood: Avoid corn, wheat, buckwheat, lentils, tomatoes, peanuts, and sesame seeds. Chicken is also problematic for this blood type, D'Adamo says. He encourages eating green vegetables, eggs, certain meats, and low-fat dairy.
• Type AB blood: Foods to focus on include tofu, seafood, dairy, and green vegetables. He says people with type AB blood tend to have low stomach acid. Avoid caffeine, alcohol, and smoked or cured meats.

On the blood type diet, you’ll avoid processed food and simple carbs. That may be enough to help you lose some weight. But any weight loss on this diet has not been linked to the blood type. There’s also no research proving that this diet can aid in digestion or give you more energy.

Even no research has been conducted, and there are no studies that show blood type can be a predictor for the development of certain diseases, his book has become one of the best selling diet books in the past two decades. This diet works on 44-62% of the people who adopt it.
