Millions of Americans experience food allergies every year, and although it won't help with your symptoms, understanding why they happen can still make a difference in how you view and approach treatment of your allergy. The cause of these food allergies can be traced back to your immune system. When you suffer from food allergies, your immune system falsely identifies a certain food or food ingredient as harmful to your body. Then, when you eat this food, your immune system triggers the release of immunoglobulin E antibodies to fight off the offending substance, as well as a chemical called histamine, which causes inflammation and is linked to many common symptoms such as a runny nose, swollen eyes, and more.

Reactions to these allergens could be minor and uncomfortable, while others could be extremely severe and life threatening. It is important to see a doctor or allergist if you're experiencing any symptoms of food allergy reactions and if you're wondering what the cause of these could be.
Anybody experiencing symptoms of anaphylaxis - an increased heart rate, shock with a severe drop in blood pressure, lightheadedness, and constriction of the airways - should seek immediate medical attention.
You can seek treatment and frequently avoid both minor and severe reactions by paying attention to the foods you eat, and their ingredients. Carrying an EpiPen can also help if used during the early stages of an anaphylaxis attack. Speak to your doctor to learn more.
