IgE (Immunoglobulin E)

Mast Cells

Mast Cells

These cells are present in almost all body tissue. But, you can find them significantly in areas like skin, nose, throat, lungs, and digestive tract.

When you eat the food item that can trigger allergies, certain cells in your immune system makes a lot of IgE. It is to deal with the part of the food, also known as an allergen that triggers an allergic reaction. The IgE released by the body gets attached to the surface of the mast cells. During the first time, you may not see any physical evidence of an allergic reaction. But, your body is now set up for one. So, the next time you consume the particular food item, the allergens start interacting with the IgE. It triggers the mast cells to release certain chemicals like histamine. Based on the tissue the chemicals are in, it triggers different symptoms.

How You Suffer From Mushroom Allergy?

The heat used to cook food or the acids in your stomach cannot break down some of these food allergens. These are also not broken down by the enzymes encouraging food digestion. So, histamines cross into the bloodstream. From the blood, it travels to different areas of the body and triggers an allergic reaction. The initial symptom is to feel itching in your mouth.

This results in gastrointestinal symptoms in people allergic to a toadstool. They can suffer from the symptoms immediately after consuming it.
