First: What is food allergy?
A food allergy is caused by an exaggerated reaction of the immune system (the body's defense system human) to the ingestion of certain substances that can sometimes be present in many products that we consume.
The amount of food eaten may or may not affect the allergic reaction in people. Some of them show symptoms even when the consumed portion is very small.
However, there is a difference between food allergy and intolerance. In the case of an allergic reaction, the body recognizes the substance as aggressive and reacts against the body itself. Intolerance is characterized by the fact that there is difficulty in digesting some specific ingredients. Allergy is usually much more serious and can even lead to death.
