Corn intolerance is a digestive condition that indicates the body’s difficulty in digesting corn. Unlike a corn allergy, which is an immune system reaction causing more immediate and severe symptoms, corn intolerance mainly results in gastrointestinal issues and discomfort.

Corn intolerance involves the digestive system’s inability to properly break down corn, resulting in discomfort and various symptoms. This is a non-immune response, contrasting with a corn allergy, which is an immune reaction to proteins in corn. Allergic reactions can include severe symptoms like hives, swelling, or anaphylaxis, while corn intolerance generally leads to milder, primarily digestive symptoms and does not involve the immune system.
Managing corn intolerance or allergy primarily involves avoiding or limiting corn in your diet. Careful reading of food labels is essential, as corn is often present in processed foods, syrups, and as a thickener. Explore alternative grains and starches, such as rice, quinoa, or potatoes. For nutrients typically derived from corn, incorporate other fruits and vegetables. Additionally, keeping a food diary can help in identifying other potential food triggers and monitoring your dietary adjustments.

Do you experience hypersensitivity to certain foods? Food intolerance symptoms, in contrast to the immediate onset of allergic reactions, can emerge hours or even days later. This delay often complicates identifying the offending foods. GetTested’s Food Intolerance Test targets IgG4 antibodies and assesses your reaction to 40 varied foods commonly associated with hypersensitivity.
If you want to analyse both allergies and intolerances we recommend this test, but if you want more extensive food intolerance tests, we have also 80 items incl. gluten and 240 items.

GetTested’s Food Intolerance Test analyses IgG4 antibodies for 80 different foods commonly involved in hypersensitivity reactions.
For those concerned about coeliac disease, we offer a simple Coeliac/Gluten Intolerance Test, which is distinct from the gluten sensitivity measured in this test. Additionally, if you suspect lactose intolerance—specifically sensitivity to milk sugar—our Lactose Intolerance Test, an exhalation test that measures hydrogen and methane, may be appropriate.
