Corn Allergy Symptoms

While rare corn allergies are becoming increasingly more common. The most common food allergies are tree nut, shellfish, fish, egg, wheat, peanut, soy, and dairy.

How to Diagnose a Corn Allergy?

As mentioned, it can be difficult to diagnose a corn allergy through standard blood tests. Symptoms vary from person to person. You should start by making an appointment with an allergist. You will most likely be asked about your family medical history and your allergy history. If you or your doctor suspect that you are allergic to corn, you might be asked to start off by eliminating it from your diet. You can keep a food diary and track everything you eat and how you felt after eating it. This will be for a specific amount of time and will be monitored by your physician. You can then test this by reintroducing corn into your diet. Severe allergic reactions can be very scary. Your doctor may want to do a “supervised trial” by monitoring your reaction in their office. If it is determined that you are in fact allergic to corn, you will need to eliminate it and ingredients derived from it completely.

Avoiding Corn

It is important to ask your doctor what other ingredients involved with corn that you will need to avoid. There are trace or undetectable ingredients that may be allowable to consume.
