Eat right, live right for your blood type

The scientific community has not widely supported the blood type diet, but alternative medicine gives it much more credence. 
It's takes just a little extra effort to make smart eating choices.

The concept of "Eat Right for Your Blood Type" is an idea popularized by Dr. Peter J. D'Adamo in his 1996 book "Eat Right 4 Your Type." According to this theory, each blood type—A, B, AB, and O—has a unique set of characteristics that influence how the body reacts to certain foods. D'Adamo suggests that by eating foods that are compatible with one's blood type, people can improve their health and decrease the risk of developing certain diseases. This concept makes sense to me, as the reason we eat in the first place is to fuel our blood which carries nutrients to the rest of our body.

The recommendations in the book are detailed and specific to each blood type. Here's a general overview of Dr. D’Adamo’s blood type eating suggestions:

  • Type A: should be a diet rich in plants, similar to a vegetarian diet as those with Type A blood may be more predisposed to certain illnesses and should focus on foods that are high in nutrients and low in fat.
  • Type B: does well with a balanced omnivorous diet that includes a variety of foods. People with Type B blood are thought to have a more robust immune system and a more flexible digestive system, which allows them to enjoy a wide range of foods.
  • Type AB: This blood type is thought to have characteristics of both A and B types. A balanced diet that includes foods from both animal and plant sources is recommended.
  • Type O: This type is advised to follow a high-protein diet that is rich in meats, fish, and vegetables but low in grains, legumes, and dairy - similar to the Paleolithic diet.

The scientific community has not widely supported the blood type diet, but alternative medicine gives it much more credence.  It is common knowledge that food affects our health, and when the body rejects certain dietary choices, we see the signs of body resistance as inflammation.  Inflammation can be in the form of weight gain, skin issues, gastrointestinal issues, body pain, mental issues and more serious diseases. Even if Dr. D’Adamo’s claims are controversial, I have seen positive health changes in my clients and in myself and family when we pay attention to our blood type

The book "Live Right for Your Blood Type" is a follow-up to Dr. D'Adamo's earlier book.  He expands upon his original blood type diet theory by incorporating other aspects of lifestyle, including exercise, stress management, and emotional well-being. The basic premise is that one's blood type can offer insights into how one should live a healthy life, beyond just dietary choices.

Some general themes in addition to diet that are covered in "Live Right for Your Blood Type" include:


D'Adamo offers guidelines for physical activity that are tailored to each blood type. For example:

  • Type A individuals might benefit from calming exercises like yoga and tai chi.
  • Type B individuals could find a balance between mental and physical well-being through moderate exercises like hiking or swimming.
  • Type AB individuals might benefit from a mix of calming and more intense activities.
  • Type O individuals might find more vigorous activities like running or weightlifting beneficial.

Stress Management

Different stress management techniques are recommended for each blood type:

  • Type A might benefit from calming techniques to deal with their naturally higher stress levels.
  • Type B is encouraged to find balance and mental clarity through activities that engage both mind and body.
  • Type AB could benefit from a combination of calming and invigorating practices.
  • Type O is suggested to focus on physical outlets for stress relief.

Emotional and Mental Well-being

The book suggests that understanding your blood type can help you better navigate relationships and emotional challenges, tailoring communication and coping methods according to your blood type.  This is a concept I am open to but would have to see more evidence.

Supplements and Medications

Dr. D'Adamo also provides recommendations on supplements, herbs, and medications that might be more effective or less risky depending on your blood type.

Even though there haven’t been extensive studies to prove or disprove Dr. D’Adamo’s claims, he has a large following and sells many books.  Ever since I heard about the blood type diet in the 90’s, I have believed in the connection.
