Allergenic foods and their symptoms

Food allergy is a reaction of the body to certain foods that occurs after eating it. Even consuming small amounts of allergenic foods can cause problems such as digestive problems, urticaria or swelling of the airways.

What keeps the body healthy against all kinds of germs and viruses is the action of white blood cells against harmful invaders that protect our body and destroy them. Unfortunately, in some cases, the body’s immune system fights back against harmful substances such as a food molecule, which can lead to complications and inflammation called food allergies. In this blog, Reezhan Tourism Restaurant, the best restaurant in Rasht , has collected some of the remarkable things about allergenic foods and their symptoms.

Causes of food allergies

When you are allergic to food, the immune system mistakenly identifies a particular food or substance in the food as something harmful. As a result, the immune system secretes cells that release antibodies to neutralize food or foods that contain allergies.

The next time you eat even the smallest amount of that food, the antibodies sense it and signal to the immune system to release a chemical called histamine and other chemicals into the bloodstream. These chemicals cause allergy symptoms.
