About Corn Allergens

Corn Allergens is an independent publication about one of the most difficult foods to avoid, and the wider health questions that corn raises.

The site exists because of a gap in the law. In the United States, nine foods must be named plainly on an ingredient label: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Corn is not on that list. A corn-allergic shopper can react to a "natural flavor," a coated tablet, or a dusted piece of fruit and have no way to trace it from the packaging alone. We started by mapping where corn hides, and the project grew from there.

What we cover

Five areas, each with its own hub:

• Corn allergy and intolerance, from symptoms and testing to the foods and products worth watching.
• Hidden corn and derivatives, anchored by our searchable ingredient finder.
• Corn and gluten, sorting out which corn foods are safe on a gluten-free diet.
• Corn nutrition, and what the research says about whole corn versus corn syrup.
• GMO corn and cash crops, including the glyphosate question.

What we are not

We are not a clinic, and nothing here is medical advice. We do not sell supplements, testing kits, or a diet program, and we are not affiliated with any brand, testing company, or advocacy group. When the evidence is mixed, we say so rather than pick the version that reads best. Read our editorial standards for how we source and review, and see write for us if you want to contribute a guide.
