An allergen is an agent that, upon entering the human body, is capable of causing an allergic reaction. This substance can make people more susceptible to it, when they have been in contact with it. When the body comes into contact with an allergen agent, it activates a mechanism that alerts the body of a foreign presence within it and what everyone knows as an allergy arises.The presence of the allergen in the body causes it to begin to generate different reactions, which give rise to the appearance of allergy symptoms.
In the environment there are infinities of allergens: in animal proteins such as animal hair or feathers; in fish, shellfish, some mushrooms, nuts (peanuts, walnuts, etc.), chemicals such as chlorine or certain detergents, cosmetics, perfumes, among others. Different types of allergens are derived from the above, among which are: pollens, epithelia and mites.
One of the most common allergens is the excrement of mites. These little animals are tiny parasites that usually inhabit carpets, mattresses, pillows, etc. Their excrement can cause allergy when inhaled by people, causing an allergic reaction in the mucous membranes. In this case, the person begins to sneeze and suffer from nasal congestion.
When food products are manufactured on an industrial scale, they must comply with certain legal requirements that should not be ignored as they could harm the health of those who consume it. As everyone knows, there are some substances that could affect the health of those with a food intolerance. This is why the laws oblige industries to have all the allergens written on each container or packages of their products, either because they have been used in their preparation, or because residues have been left at the time of production. other foods.
One of the allergens that must be shown (clearly and visibly) in food products is gluten, which is present in many cereals. Such as oats, wheat, rye, barley, etc.
