General Information

Allergies vs. Intolerances

 

 

What is food allergy?

 

A food allergy is an abnormal response of the body to a certain food. It is important to know that this is different than a food intolerance, which does not affect the immune system, although some of the same signs may be present.

 

 

What causes food allergy?

 

Before having a food allergy reaction, a sensitive person must be exposed to the food at least once before. It is the second time the person eats the food that the allergic symptoms happen. At that time, when IgE (Immunoglobulin E) antibodies react with the food, histamines are released, which can cause hives, asthma, itching in the mouth, trouble breathing, stomach pains, vomiting, or diarrhea.

 

 

What is the difference between food allergy and food intolerance?

 

Food allergy causes an immune system response, causing symptoms that range from uncomfortable to life-threatening. Food intolerance does not affect the immune system, although some symptoms may be the same as in food allergy.

 

 

What foods most often cause food allergy?

 

Approximately 90 percent of all food allergies are caused by eight foods:

 

 

                                          Eggs

                                           Fish

                                           Milk                               

                                           Peanuts

                                           Shellfish

                                           Soy

                                           Tree nuts

                                           Wheat
