  1. As a person who has a severe intolerance to the lectins found in certain meats, vegetables, and fruits, including tomatoes, I take issue with your statement that lectins are not harmful.
    As a result of my intolerance, I made a lifestyle change several years, and follow The Blood Type Diet. As a person with Type B+ blood type, eating tomatoes , and certain other lectins containing foods has, and can be detrimental to my health.

    1. Hi Martha. It’s really great to find someone really genuine.
      Thanks for point out the details. Actually you are right. It is an important fact that lectins are responsible for severe allergic reactions- and it is official with all medical guidelines. Still, I have written that it is not harmful. Let me clear it first What I have said is for general understanding. It is for those who reacts without knowing their health status. Actually, these days many people get tensed with even a simple word like problematic “anything” associated with anything especially food. Without knowing the actual details they get panic attacks for uncertainty. I think it’s not good. Everyone should be aware of the fact before reacting. Like you have, you are well aware that such food is harmful to you and you are careful about that. It is great and I really appreciate your help.
      Thanks

      1. Hey l must say ur article is well written but on bell peppers how do you remove lectins on them? Does removing seeds and peels on tomatoes remove all lectins? And what’s ur option since some online article says organic vegetables or organic fruits/organic grains have no lectins compared to non organic produce? Thanks

        1. Hi George,
          Thanks for writing back. You must know that there is no way to determine if it’s 100% lectin-free or not. This is not possible to determine at home. Although you can try your best by following every step to remove lectins in vegetables. Organic fruits and vegetables can contain lectin. The quantity may differ but it’s there. So if you are intolerant then get help from a dietician else try your best to clean and cook those foods before eating. Precaution is better than cure.

    2. Hi Martha:

      When I researched my current blood-type diet, I noticed a lot of lectin no-no’s in my blood group A+. My needs are anti-inflammation and reduced edema.

      You may have found similar results. ALL THE BEST!

  2. Hey! Do you happen to know if after said legumes, potatoes, etc. are boiled, should they be drained and then added to say a soup, instead of being added to a soup that is cooking? Would the water it was boiled in hold the released lectins? Also, random theory. If lectins are to fight off pests and disease, does that mean GMOs could carry more lectins since they are designed to off put any pests? Curious to know if you had any thoughts on that. Thanks!

    1. Hi Ellen, thanks for reaching out.
      First of all, I must say you have a point. Boiling is an effective way of getting rid of lectins and yes, it will always be there in the substrate. So technically you can say- it is better to leave that. But there are two important points to remember- 1.) Lectin is now inactive after boiling and 2.) Boiling also removes some natural enzymes & minerals essential for your health. So I think, I don’t mind using it all together as I’m not that much allergic to such food. But It should be noticed for sure.
      Next is about GMOs – Yes, for sure It may contain more lectins, at least theoretically it can be proved, but there is no such recorded evidence for that so its just a thought.

  3. Dear, as Belgian, we are french fries lovers. I ate 8 weeks lectinefree and we are about trying to add them again, differently prepared.
    French fries are cooked at high temperatures in oil. Does that remove the lectines too?
    Or would it be better to precook the potatoes in a pressure pan, than peel them , cut them in fries and then bake them in oil.??

    Thank you for the tips.

  4. Lectins are harmfull to everyone regardless of whether you are allergic or not. Lectin breaks down the protective enzymes that protect the walls of your intestines. When this happens, it allows fecal matter to be absorbed through them and this is toxic and can cause infections. Many doctors end up with patients who have internal infections and they can’t figure out why. It’s because the cause isn’t staring anyone in the face. It’s subtle and complex. If you know anyone that gets internal infections often, tell them not to eat lectin rich foods very often.

    1. I definitely agree and always suggest so to my readers. Understand the food you eat and avoid anything harmful, especially those edibles with a high lectin content. These foods may not show any visible impact on you yet they will have a significant effect on your health.
