Your AB Blood Type Diet Chart

Your blood type diet chart for your AB type bloodThose with Type AB blood have a unique physiology that inherits characteristics of both Type A blood and Type B blood physiologies. This means they face some particular challenges in taking proper care of their bodies and eating right. While those with Type A blood generally do better without meat, and those with Type B blood are encouraged to include meat in their diet, those with Type AB blood are caught somewhere in between.

If you have Type AB blood, one of the guiding principles of your diet should be moderation. Meat is necessary but your digestion will not be able to handle too much. Many grains provide needed energy and nutrients but consuming too much will imbalance your body’s pH. It is also important to stay away from foods that are incompatible or harmful to the Type AB blood physiology. Below is a chart that will help you make the right choices for a proper Type AB blood type diet.

Dr. Lam,
I have taken your supplements for 17 months now and I am recovering very well from AFS. I work full time, can do 90 minutes of power yoga, dance at a concert, have sex, go on a camping trip, etc. Crashes are rare and recovery is very fast. I have rebuilt my lost collagen, but not muscle mass. I am weak from not doing intense exercise.

    Hello Dr. Lam,

    I have one more question….
    What about Coconut water for Type AB and A?

    • Dorine Lam RDN says:

      Coconut is to be avoided for ALL blood type. I don’t know about coconut water.

    I gained a lot with this website,
    Thanks a lot.

  • Sharron says:

    Hi Im 58 and fed up of my many dietry problems so have decided to start this diet. Just a quick question, My blood group is A- (negative) so are there any alterations I should make?

    • Dorine Lam RDN says:

      Keep following the Blood type A diet.

      Blood Type Diet is based on how the protein in the food called lectin affects blood agglutination. The blood type diet is fitting for most of the people. Due to tremendous variation in individual constitution, there is no guaranteed success with it. If you would like to follow the blood type diet, I would recommend that you follow it vigorously for 3 months, even though you don’t see much harm or benefit in certain food. After 3 months, if you see no improvements in your health, then you can deviate and use the blood type diet as a general guideline and not overeat the foods that should be avoided for your Blood Type, but take them with care and in small amounts.
