Allergies are when a person’s immune system identifies a harmless substance as a threat. This leads to them attempting to fight it off. Their attempt to defend themselves produces a variety of unwelcome symptoms. These range from the mildly irritating to the potentially deadly.
Allergens are basically allergy triggers. In principle, any substance can be an allergen. In practice, some substances are known for being particularly likely to cause allergic reactions. Many of these are common foods such as dairy products, eggs, peanuts and tree nuts, soy, fish and shellfish, wheat, and sesame seeds.
Allergy Protein Function
A true allergy is triggered when the body reacts to one of the proteins found in a food item. Proteins are often known as “macronutrients” because they are large molecules. They also tend to be very complex.
Allergy Protein Mechanism
When the body detects the protein it mounts an immunoglobulin E (IgE) response. In other words, the body’s white blood cells release antibodies to try to destroy the protein. This mistake triggers further reactions within the body. These produce the noticeable symptoms of an allergy.
