How to Use the Food Allergy Checker
Select every allergen that applies to you, then choose a food from the list. The tool cross-references the food's known ingredients against your allergens and immediately tells you if any match. This is based on typical ingredient compositions — always verify with the product label for packaged foods.
Understanding Food Labels
In the US, the FDA requires the top 9 allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, sesame) to be clearly declared on food labels. Look for them in bold or in a separate "Contains:" line. Trace amounts from shared equipment may appear as "May contain" warnings.
Frequently Asked Questions
This tool provides general guidance based on typical recipes. For severe or anaphylactic allergies, always read the actual product label and consult your allergist before eating unfamiliar foods.
If you experience hives, swelling, or difficulty breathing, use your epinephrine auto-injector if prescribed and call emergency services immediately. Mild reactions may be managed with antihistamines, but medical evaluation is recommended.
