ABO Blood Type Specific Lectins in Edible Foods

This is an alphabetical list of Foods containing ABO Blood Type Specific Lectins, from edible Plant and Animal sources.

Most lectins, in plant species, are NOT ABO blood type specific. Even fewer EDIBLE plants have lectins that are ABO type specific.

This list does conflict with the information of the various incarnations of 'blood type diets', as far as specific foods agglutinating certain of the ABO blood types only. However, this information below has been derived directly from the published scientific literature and studies which are listed in the references which follow the list. It is not known where the authors of these diet books came up with their ABO blood-type agglutination data. It appears to be false when compared to published scientific studies.

The first section has a list of foods, in alphabetical order for easier searching, their scientific names, and which blood types are agglutinated by them.

The researchers who did this testing have published their findings. Their work covers many medicinal plants too which I did not show here.

also included below the table is additional information on the allergenic potential of the foods where this information is available; even though allergy is not associated with lectin specificity, this information may be helpful to those using this list. Agglutination activity, mitogenesis, etc. are all from results of laboratory study of the lectin with blood and cells in vitro, unless noted.

Most interesting to those following the blood type diet may not be whether a food causes agglutination or not, but that almost every food reacts identically with each blood type. So, what is the basis for the Blood Type Diet???

Read what Dr. Arpad Pusztai, a famous lectin researcher, has to say about ABO blood type type specific lectins   (this page will open into a 2nd window).
