Allergies / intolerances
From a medical point of view, allergy is an overreaction of the immune system to certain substances known as allergens. The allergens could be such food component as proteins, colourants and preservatives. In contrast to intolerances where metabolism reacts to the consumed substance, the allergies could be identified by active immune reactions.
As a rule, nutritional substance allergy is immediate-type allergy, which means that immune response takes place immediately after the contact with the allergens. Among the typical body’s reactions are conjunctivitis, hay fever, asthma or exanthema. Thus, the best therapy is to avoid the allergens. It is recommended that you study the ingredients and labelling of allergens of the consumed products.
