The blood type diet has been around since 1996. In 2016, the book Eat Right 4 Your Type was updated with a 20th-anniversary edition. The diet was created by naturopath Peter J. D’Adamo. It is based on the idea that certain foods are more easily digestible than others, depending on your blood type. By eating food that is more bioavailable, your focus, satiety, and energy levels improve, and weight loss or weight maintenance becomes easier. Here’s what you need to know about this diet.
What Can I Eat on Blood Type Diet?
Type O Blood
According to this diet, people with type O blood should eat a high-protein diet focusing heavily on lean fish, poultry, lean game meat, and vegetables. As people with type O blood tend to suffer from gastrointestinal distress, they should limit their consumption of dairy, beans, and grains.
People with type O blood typically suffer from health conditions, such as asthma, hay fever, other forms of allergies, and arthritis.
Type AB Blood
According to D’Adamo, people with type AB blood usually have low stomach acid. Therefore, they should avoid smoked and cured meats, alcohol, and caffeine. Their diet should consist primarily of leafy green vegetables, dairy, tofu, and seafood.
People with type AB blood do not suffer from as many allergies as people with type O blood. However, they are likely to suffer from anemia, cancer, and heart disease. The risk of developing anemia makes leafy green vegetables, tofu, and seafood critical.
Type A Blood
D’Adamo suggests that people with type A blood benefit the most from a vegetarian diet. As people with type A blood usually have a sensitive immune system, they should try to eat only fresh, organic fruits, vegetables, beans, legumes, and whole grains.
People with type A blood are predisposed to heart disease, cancer, and diabetes. To mitigate this risk, their diet should consist of healthy, high-fiber, high-protein foods, and limit high-fat foods.
Type B Blood
D’Adamo states that people with type B blood should revolve their diet around low-fat dairy, eggs, green vegetables, and occasional meat. Foods that are likely to be problematic include chicken, corn, wheat, lentils, sesame seeds, peanuts, and tomatoes.
People with type B blood are usually fairly susceptible to autoimmune disorders, such as multiple sclerosis, chronic fatigue, and lupus. Their diet eliminates potential triggers for sensitivities.
The Final Word
This diet is probably effective for people who are generally healthy. However, anyone with a medical condition, like diabetes, should speak with a physician before making any dietary changes. There is nothing inherently wrong with this diet. All four diets eliminate processed foods and simple carbohydrates, and this makes weight loss or weight maintenance easier.
It also may make you feel healthier and happier. However, if you don’t like the recommended foods for your blood type, you are not going to stick to the diet. If you would like to try this diet, speak with your physician, and see if it is safe for you to follow.
