Adzuki beans are also known as red beans and are the species Vigna angularis, so are similar to Vigna mungo (black gram beans), Vigna unguiculata (black eyed peas) and Vigna radiata, which are green gram beans (also known as mung beans).

Adzuki beans are legumes in the family Fabaceae which includes many types of beans, pea, peanuts, lentils, lupin and soya.

To date there are no recorded allergens for adzuki beans by the World Health Organization (WHO), because there have not been enough study into allergic effects from this food. If you are interested in what is needed by the WHO before they add an allergen to their allergen database you can check that out HERE.

Mung beans contain 7S seed storage proteins and Bet v 1 proteins which are linked to Pollen Food Allergy Syndrome. There is a possibility that adzuki beans contain similar proteins.

Legumes are difficult to categorise when it comes to food intolerances, the more reliable sources have shown them to be high in histamine but low in salicylates and lectins.

Lectins in particular can be reduced by cooking legumes well. Canned beans are pre-soaked so cause less issues than those that are dried. Dried pulses need to be soaked well before cooking to reduce the lectins in the food.

You can read more about Food Intolerances on the dedicated Food Intolerance Page.

If they contain Bet v 1 proteins then adzuki beans can be linked to Pollen Food Allergy Syndrome.
