How to Read a Food Label When You Have Food Allergies

Food label

For those of us with food allergies, the most obvious way to prevent an allergic reaction is to simply avoid eating the food. This sounds like a no-brainer, right? For many of us, avoiding food allergens is harder than it looks. With all the confusing ingredients listed on a food label, how can you really be sure you are choosing foods that are allergy-safe? The key is to understand how to read a food label.

Food Allergen Statement Warnings

Thankfully, all FDA-regulated manufactured food products that contain a “major food allergen” (milk, wheat, eggs, peanuts, tree nuts, fish, shellfish, and soy) as an ingredient are required by law to list that allergen on the product label in plain English. Such ingredients must be listed in the ingredient list or:

  • The word “Contains” is followed by the name of the major food allergen, i.e. “Contains peanuts”
  • A parenthetical statement in the list of ingredients, i.e. “casein (milk)”

Food manufacturers may also include the following statement warnings on their food labels:

  • “May contain”
  • “May contain traces of”
  • “Manufactured on equipment that processes”
  • “Manufactured in a facility that processes”

While this language is helpful to food allergic consumers, Allergy Superheroes (@Allergyheroes on Twitter) makes an important distinction about manufacturer statement warnings:

So, how can we be sure to avoid foods we’re allergic to?

Thankfully, the Food Allergen Labeling and Consumer Protection Act (FALCPA) has made it easier for food-allergic consumers to read a food label.

Enacted in 2006, FALCPA requires all food labels in the United States to list ingredients that may cause allergic reactions. The purpose of FALCPA is to prevent manufacturers from using misleading or confusing methods to list ingredients. However, it is still important to know how to read a food label for unexpected sources of allergens.

Food Allergy Research and Education (FARE) has compiled a full list of allergen ingredients to help you decipher the confusing language of food ingredients.

Obligatory Disclaimer: Please keep in mind that all labels should be read carefully before consuming a product, even if you have safely eaten it in the past.

There, it’s been said. On to the good stuff.

Common Ingredients to Avoid for a Peanut-Free Diet

As a long-time peanut allergy sufferer, I can attest to the fact that peanuts can be found in surprising places. Some of the more obvious ingredients to avoid include:

*The FDA exempts highly refined peanut oil from being labeled as an allergen. Studies show that most allergic individuals can safely eat peanut oil that has been highly refined (not cold pressed, expeller pressed, or extruded peanut oil). Ask your doctor for advice.

Mixed nuts

These guys are freakin’ (tree) nuts.

Common Ingredients to Avoid for a Tree Nut-Free Diet

A tree nut allergy is one of the most common food allergies in adults and children. According to FARE, if you’re allergic to one type of tree nut, you have a higher chance of being allergic to other types.

For this reason, your doctor may recommend to avoid all tree nuts, as well as any of these ingredients:

  • almond

*Coconut has typically not been restricted in the diets of people with a tree nut allergy. However, in 2006, the FDA began identifying coconut as a tree nut. Ask your doctor if you should avoid coconut, not me.

So there you have it.

Keep in mind that information on this website should not be mistaken for medical advice. Remember to always consult your doctor first with questions about your food allergy.

Finally, if you are ever unsure about an ingredient in a product, don’t be like me. Avoid the food altogether and reduce your risk of racing to the ER in a Ferrari. It’s better to be safe than sorry.

More about that story later 😉
