Bean Allergy Means Cross Reaction With Other Legumes
MECHANISM OF ALLERGY TO BEANS
Beans, which belong to the genus Phaseolus vulgaris , in South America began to be grown and eaten as early as 7000 years ago. And the ancient Greeks and Romans used it as a medicine to heal wounds.
It was in those days that the first mention of an allergy to beans appeared. And this is not surprising, because this product contains 75% protein. This is the same as in the meat of any animal or bird. And where there is protein, there is allergy …
It occurs due to an overly active reaction of the immune system to the substances contained in this plant, a representative of the legume family. Immediately after ingestion, the body of a sensitive person mistakes the product for an enemy agent and begins to defend itself with the production of antibodies, which eventually stimulate the synthesis of histamine. Antibodies fight bean proteins, perceiving it as an infectious agent. And histamine is trying to protect the body from this imaginary infection. Excess histamine causes soft tissue inflammation in various parts of the body.
To soften this reaction, the beans should be soaked in water for 10-12 hours and then boiled for at least an hour.
This is how the beans are prepared for Ukrainian borscht, which without it will not only have no taste, but also the necessary nutrients. Namely:
