Food allergies are a serious health concern that can lead to mild reactions like itching and hives or more severe symptoms such as anaphylaxis. For the millions of individuals managing food allergies, reading food labels accurately is a critical daily task. While manufacturers are required to disclose certain allergens, understanding how to interpret this information ensures safety and peace of mind. This guide will walk you through the key components of reading food labels for allergens.
Understanding the Big 9 Allergens
In the United States, the Food and Drug Administration (FDA) mandates the disclosure of the “Big 9” major food allergens on packaged foods. These are:
Milk
Eggs
Fish
Shellfish
Tree nuts
Peanuts
Wheat
Soybeans
Sesame (added in 2023)
These allergens are responsible for the majority of serious allergic reactions. When any of these are present in a product, they must be clearly identified on the label, either in the ingredient list or in a “Contains” statement following it.
Note that allergens must be listed by their common names. For example, instead of “casein,” a label must say “milk” since casein is a milk protein. This makes it easier for consumers to identify potential allergens.
Hidden Sources and Alternative Names
While the major allergens must be declared, they can still hide behind scientific or unfamiliar names within the ingredient list. Learning these aliases is essential for those with food allergies.
Here are some examples:
-
Milk may appear as whey, casein, lactose, or curds.
-
Eggs can be listed as albumin, globulin, or livetin.
-
Wheat might show up as semolina, spelt, or durum.
-
Soy can be referred to as soy lecithin, textured vegetable protein, or hydrolyzed soy protein.
-
Tree nuts might be listed by individual names like almonds, cashews, or pecans.
For this reason, even if a “Contains” statement is absent or seems safe, it’s vital to read the full ingredient list carefully. Additionally, some non-Big 9 allergens—like corn, mustard, or coconut—are not always required to be labeled, depending on regional regulations. People allergic to these should be extra cautious.
Decoding Advisory Statements
Advisory statements like “May contain,” “Processed in a facility with,” or “Made on shared equipment with” are voluntary disclosures. They are meant to warn consumers about potential cross-contact with allergens during manufacturing.
For example:
-
“May contain traces of peanuts.”
-
“Manufactured on equipment that processes tree nuts.”
These warnings do not guarantee the presence of an allergen but signal a possible risk. There’s no standardized threshold for what constitutes cross-contact, which means that levels can vary widely from one brand to another. If you are highly sensitive, it’s safest to avoid products with any advisory warning about your allergen.
It’s also important to note that not all companies include these statements. A product without an advisory label isn’t necessarily safer than one with it. Consumers should contact manufacturers directly when in doubt.
Tips for Safe Shopping and Eating
Beyond label-reading, there are practical steps that can help manage food allergies effectively:
Use a scanner app: Apps like “Spoonful,” “Yuka,” or “ContentChecked” can scan product barcodes and alert users to the presence of allergens.
Shop trusted brands: Some brands specialize in allergen-friendly foods and follow stricter practices to prevent cross-contact. Seek out labels such as “Certified Allergen-Free” or those vetted by allergys organizations.
Stay updated: Manufacturers can change ingredients without announcing it prominently. Always check the label—even for products you’ve used before.
Contact companies: If a label is unclear or a product lacks an advisory statement, reach out to the manufacturer’s customer service for more information.
Educate your family: If someone in your household has allergies, make sure everyone who prepares or buys food understands how to read labels and spot allergens.
Beware of imported foods: Not all countries have the same labeling laws. If buying imported products, double-check that allergens are clearly stated, or look up unfamiliar ingredients.
Know when to avoid risk: For highly sensitive individuals, even a small amount of allergen can trigger a reaction. When in doubt, choose another product rather than taking a chance.
Conclusion
Reading food labels for allergens is a skill that, once developed, becomes second nature. With allergens being hidden in unexpected places and labeling laws varying across countries, vigilance is essential. By understanding common allergens, decoding ingredient lists, being cautious of advisory warnings, and following practical shopping tips, individuals with food allergies can significantly reduce their risk and enjoy greater food safety.
