    I was diagnosed with Osteoarthritis and my blood group is O+. Am confuse in eating meat so that the symptom will not increase. Please advise me on my meal type.

    • Dorine Lam RDN says:

      In general, one with osteoarthritis should eat less meat, which is contrary to Blood Type O diet. 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.

    Cayenne pepper does not bother me (AB +) however my wife is (0) and she cannot eat it. Why is that?

    • Dorine Lam RDN says:

      Cayenne pepper is neutral for AB+ and beneficial for Blood Type O. If your wife can’t not tolerate it, it may have to do with her digestives health.

      Digestion issues, such as diarrhea, constipation, gastritis, acid reflux, IBS are common in Adrenal Fatigue. This can be due to many reasons, including assimilation as well as internal dysbiosis issues.

    which protien minerals and vitamins are essential for good hairs for O positive group….?

    • Dorine Lam RDN says:

      There are many aspects to good hairs, such as thyroid health, female hormone balance, type of hair care, etc. The supplement in general for hair growth is biotin, nothing specific for blood type O.

  • Joyce Handy says:

    I have been researching blood type eating for a while.Kind of heard when there are 2 types is the household A and O
    However my question is if you process corn for Masa does this change the Lectin for blood type acceptance. The process is called Nixtamalization. Basically boilng corn in water with added Lime.
    Also will fermenting foods change this. also can coconut oil be used by O and A? also Chia seed?

    • Dorine Lam RDN says:

      In general, traditional food preparation such as soaking then cooking, sprouting, and fermenting, will decrease lectins and free up the good nutrients.

      Blood Type Diet is based on how the protein in the food called lectin affects blood agglutination. The diet is founded by Dr Peter D’adamo. There are some principles in the blood type diet that are not accepted in conventional medicine and their recommendations. Ie coconut and soy are some of these discrepancies.

  • Breanne says:

    I’m 25 and have broken out over the last several months with severeacne and itchy skin. Is it possible that this is due to a food sensitivity? I’ve been told the worst one for O is dairy.

  • Sandra says:

    Could you please expound why avocados and coconut products should be avoided by type O’s? Is it due to weight issues, joint issues, etc? Thanks much!

  • Cookie says:

    Any suggestions of what proteins to eat for type O vegetarians, I eat eggs and milk/yogurt/cheese but not good for me.

  • Stephanie says:

    I’m sad shouldn’t have coffee and tea

  • PABLO says:

    If essene and ezekeil are not gluten free, why are they ok to consume if your blood type O?

    • Dr.Lam says:

      For the blood type diet, the key is the lectin and how they affect the agglutination of your blood. It is not the gluten but the protein lectin that is important. With sprouted bread the protein structure of the grain is actually changed and may cause less agglutination in your body.

        Thank you for this listing. I’m reading it and am in complete shock. I’ve been dieting for years and never have a lot of long term success. Looks like I’ve been eating all of the wrong “health” foods for my blood type. I eat lots of greek yogurt and boiled eggs. I’ll be cutting that out.
