How to Decode Food Labels for Hidden Corn
Avoiding corn isn’t always easy because it hides under many different names on food labels. If you’re sensitive or allergic to corn, knowing how to decode labels can protect your health and give you confidence when grocery shopping. Here’s how to spot hidden corn and shop safely:
- Know Common Corn-Derived Ingredients - Corn is often disguised as ingredients like: Citric acid, Dextrose, Maltodextrin, Modified food starch, Corn syrup, and high fructose corn syrup, Natural flavors, Corn starch, Ascorbic acid, Sodium citrate Xanthan gum.
These can all be derived from corn, wheat, tapioca, or other sources — so knowing the source is crucial.
2. Check Allergy Statements and Labels - Unfortunately, corn is not a top allergen that companies are required to list clearly on packaging. Unlike peanuts or gluten, corn-derived ingredients may not be obvious in the allergy warnings. This means you need to rely on ingredient lists and sometimes contact manufacturers directly.
3. Contact Manufacturers When in Doubt - If an ingredient could come from corn or another source, don’t hesitate to reach out to the company. Many brands have customer service or ingredient specialists who can clarify sourcing.
4. Be Wary of “Natural Flavors” and “Spices” - Terms like “natural flavors” or “spices” can mask corn derivatives. These terms are vague and often do not disclose the true source of the ingredient.
5. Use Trusted Brands and Resources - Stick with brands known for transparency and corn-free options. Using resources like cornfree.ca can save you time and frustration.
