Allergens
An allergen is a substance that causes an allergic reaction. A completely harmless substance for one may cause a strong allergic reaction for another.
There are 3 main ways of allergens entering the body:
- Inhalation - inhalation of allergen-contaminated air;
- Alimentary-product or other substance containing an allergen entering the digestive tract
- Contact - direct contact of the allergen with the skin and mucous membranes.
The strength of the allergic reaction does not depend on the amount of allergen that enters the body - even the smallest dose of the allergen can cause anaphylactic shock. The strength of the allergic reaction is mainly determined by the way the allergen enters the body, the strength of the allergen and the intensity of the contact.
Today, thousands of allergens are known, which are divided into several groups according to the source of origin. Dust, household, food, industrial, drug, infectious, helminth, insect allergens are distinguished.
Hallen called food allergy an idiosyncrasy, which means an unusual reaction to a ordinary food. Food allergy appears at the first intake of food and continues throughout life. Allergic reaction to the product depends on its chemical composition, glycoprotein content and concentration of low-molecular compounds.
