Catfish for blood type o

  1. 9 years ago

    I enjoy eating catfish, but I recently discovered they are bad for blood type o. Will you please tell me why?

    Hello Cory,

    According to Blood Type diets certain foods contain "lectins" that cause agglutination of certain blood types. This could, theoretically, result in allergic types of reactions.

    Catfish is listed as a NO food for blood type O.

    If you have never had any type of adverse reaction to catfish and you are a blood type O, it is possible you tolerate it well in moderation.

    Best of Health,
