Though there are over 160 known food allergens in total, the eight listed above account for over 90% of all allergic reactions to food.

Though it might seem easy to avoid these 8 major food allergens in your diet with a little effort, foods containing Big 8 ingredients are much more common than may you think and are sometimes difficult to identify at first glance.

Keep in mind that what you are allergic to may change throughout your life. Typically, children grow out of allergies associated with dairy, eggs, and wheat over time. However, it can work the opposite way as well. Sometimes, adults find themselves newly allergic to foods that previously didn’t affect them in a negative way.

Allergy prevalence levels also shift from time period to time period, depending on factors like food trends linked to childhood exposure levels, environmental factors, and evolutionary progress based on a culture’s hygiene standards. In fact, the Centers for Disease Control & Prevention report that the prevalence of food allergies in children increased by 50% between 1997 and 2011 alone!

So, with allergens lurking in most supermarket foods, how should you protect your family? Learn to read and interpret product labels!

How to Read Food Labels for Allergies

The Food Allergen Labeling Consumer Protection Act of 2004 requires that all food products regulated by the FDA clearly indicates whether a product contains any of the Big 8 allergens through clear text onthe product package.

This is typically done by either including the potentially allergy-causing ingredient in the Ingredients list and identifying it by its common name (Ex: “Soy” instead of “Lecithin”), or by including a separate list of ingredients below the main one, and listing only potential allergens there to make sure their presence is emphasized.

While examining the Ingredients list, you may also come across disclaimers that begin with “May contain…” or “Processed in a facility with….” While these statements are not regulated by the FDA, they should definitely not be ignored. Though foods with these disclaimers may not actually possess the allergen culprit in question, there is a high chance that their ingredients have been cross-contaminated with it. Meaning, if someone in your family is severely allergic to an ingredient, you should avoid foods that feature such statements in order to greatly minimize the risk of an allergic reaction.
