Which Grocery Apps Let You Filter Products by Allergen?

Several apps, including Fig, Spokin, Open Food Facts and Fooducate, say they let you filter grocery products by allergen or point out allergens in them. Their pages describe different things, from finding products that fit an allergy profile to checking a product you scan. Guiltless, which we make, also has allergen filters, where the filters are supported. Some store websites have allergen options too. In one search for snack bars, Walmart.com and Amazon.com both had allergen options.

Apps that filter products by allergen or point out allergens

What each company says its app does:

• Fig: you set up a profile that can include your food allergies, and Fig shows which products at stores fit your needs. Its barcode scanner checks ingredient labels. The free version includes five scans a month and unlimited searches; store filtering needs an upgrade. Available in the US. Its app page and App Store listing don't give a list of allergens.
• Spokin: find new products that are already filtered by your allergens, with reviews from people who have tried them. It's an iPhone app, and Android users can join an email list to be notified when the app is available for Android. Neither its app page nor its App Store listing lists specific allergens.
• Open Food Facts: set up allergen alerts. A product shows green if it matches your criteria and red if there is a problem. Its App Store listing names milk, gluten, eggs, soybeans, nuts, fish, celery, mustard, sulfites, peanuts, sesame seeds, crustaceans, mollusks and lupin.
• Fooducate: in its words, "Uncover gluten and allergens in your food" and "Choose allergen free alternatives." It names gluten, milk, lactose, soy, peanuts, tree nuts, eggs, fish, shellfish, sesame and corn. These allergen features are part of its paid "Gluten & Allergies" in-app purchase.
• Guiltless (our app): it asks about allergies when you set up the app. When you set an allergen filter, the app stops listing products that contain that allergen, where the filter is supported. The filters are gluten, dairy, soy, grain, shellfish, egg, nut and peanut. There is no fish, sesame or wheat filter.

Before you pick one, check that it covers your allergen. The apps name different allergens on their pages, and some pages don't give a list of allergens. Then decide whether you want an app that finds products for you or one that checks a product you scan, and read that app's description.

Store websites with allergen filters or labels

In one search for snack bars, these options appeared. Other searches may show different ones.

• Walmart.com: the "Special Diet Needs" filter had a "Nut-Free" option.
• Amazon.com: the "Free From" filter had "Dairy Free" and "Egg Free" options, as well as "Gluten Free."

Thrive Market labels products by allergen. Its website lists products under groups such as Peanut-Free, Tree Nut-Free, Dairy-Free, Egg-Free, Soy-Free, Fish-Free, Crustacean Shellfish-Free, Sesame-Free, Wheat-Free and Big 9 Allergen-Free.

A gluten-free filter is not a wheat-allergy filter

A food labeled gluten-free can still contain an ingredient made from wheat. Under FDA rules, a gluten-free food must have less than 20 parts per million of gluten. It cannot contain wheat itself or an ingredient made from wheat that was not processed to remove gluten, such as wheat flour. An ingredient made from wheat, such as wheat starch, is allowed if it was processed to remove gluten and the finished food stays under that limit. If the label names wheat, the FDA requires an asterisk or other symbol next to the word, linked to a statement that the wheat was processed to meet the FDA's gluten-free requirements.

The FDA's gluten-free labeling rule matters for any gluten filter, in an app or a store, including the Guiltless gluten filter and the "Gluten Free" option in Amazon.com's "Free From" filter. A gluten filter answers a different question from "Is there wheat in this?" To check for wheat, read the ingredient list and the "Contains" statement, as the next section explains.

How to check a US food label for allergens

US law names nine major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame, according to the FDA. Sesame was added to this list on January 1, 2023, under the FASTER Act.

An FDA-regulated packaged food that contains one of these nine allergens must name it in one of two places:

• In the ingredient list, in parentheses after the ingredient, such as "whey (milk)" or "flour (wheat)."
• In a "Contains" statement right after or next to the ingredient list, such as "Contains wheat, milk, and soy."

A few more things to know:

• "May contain" is voluntary. The FDA says warnings such as "may contain" or "produced in a facility that also processes" are not required by law. A package without one is not a sign that the product is free of cross-contact.
• The FDA's allergen labeling rules don't cover every food. They do not apply to meat, poultry and egg products, which the US Department of Agriculture regulates. They also do not apply to highly refined oils, raw agricultural commodities or most foods sold without a packaged label.
• Ingredients can change. The FDA suggests reading the label every time you buy a food, even one you have eaten before.
