Food Labels: How to Read Them (and What to Watch Out For)
One of the very first things I learned when we became a food allergy family was how to read food labels. This was also around the time I was finishing my degree and taking a nutrition class. Between that coursework and a lot of trial and error, I quickly learned how to spot unsafe ingredients and recognize which products weren’t safe for our household.
At first, we avoided a lot of foods. While that felt safer in the beginning, it wasn’t sustainable long-term. I knew we — and now you — needed to feel comfortable reading labels and confidently identifying products we couldn’t eat.
The good news? There’s no need to enroll in a college nutrition course or spend hours wandering grocery aisles reading every label “just in case.”
Once you know what to look for, reading food labels becomes much easier.
Step 1: Look for the Big 9 Allergens
In the U.S., food labels are required to clearly identify the Top 9 Allergens:
- Milk
- Eggs
- Peanuts
- Tree nuts (such as almonds, walnuts, cashews)
- Fish
- Shellfish
- Soy
- Wheat
- Sesame (added in 2023)
Tip: These allergens must be listed either:
- In parentheses after an ingredient (for example, albumin (egg)), or
- In a bold “Contains” statement near the ingredient list
Step 2: Don’t Skip the Fine Print
Some ingredients hide allergens under unfamiliar names. Common examples include:
- Casein
- Whey
- Albumin
- Lecithin
Always read the entire ingredient list, not just the bold “Contains” statement.
Step 3: Understand “May Contain” & Cross-Contact Warnings
Statements like:
- “May contain…”
- “Processed in a facility with…”
indicate a risk of cross-contact.
Every family handles this differently. Some avoid these products completely, while others make informed decisions with guidance from their allergist.
Step 4: Watch for Seasonal or Recipe Changes
Manufacturers can change recipes at any time — often without warning.
Even if a product has been safe before, always re-read the label every time you buy it.
Step 5: Be Cautious with International & Specialty Products
- Other countries follow different allergen labeling laws
- Imported foods and specialty items may not meet U.S. labeling standards
When in doubt, it’s best to skip the product or contact the manufacturer.
