When Pasta Night Turned Into a Mystery: My Family’s E Number Dilemma

Last spring, I watched my seven-year-old son, Ethan, push away his plate of spaghetti—his favorite meal. Within minutes, he developed red blotches on his cheeks and started complaining about a headache. As a parent, you know that sinking feeling: What did I miss? I’d checked the label for peanuts and gluten, but I hadn’t thought to look for those mysterious “E numbers.” That night, I promised myself I’d learn how to scan your food for E numbers – here’s how I did it, and how you can too.

What Are E Numbers and Why Should You Care?

E numbers are codes for substances used as food additives within the European Union and some other regions. These include preservatives, colorants, emulsifiers, and more. While many are considered safe, some can trigger reactions in sensitive individuals—especially children1. In the US, these are usually listed by their chemical names, making them harder to spot.

  • Common E numbers: E100 (Curcumin), E200 (Sorbic acid), E621 (Monosodium glutamate/MSG)
  • Possible reactions: Headaches, skin rashes, hyperactivity in children2
  • Who’s at risk? Kids, people with allergies, and those with dietary restrictions

The European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) both regulate food additives, but their labeling rules differ.

How to Scan Your Food for E Numbers – Here’s How

If you’re like me, you’ve probably squinted at ingredient lists, trying to decipher cryptic codes. Here’s the step-by-step process I wish I’d known sooner:

  1. Check the Ingredient List: In the EU, E numbers are usually listed directly (e.g., “E102”). In the US, look for chemical names (e.g., “Tartrazine” instead of “E102”).
  2. Use a Food Scanner App: Apps like Food Scan Genius let you scan barcodes and instantly flag E numbers and additives.
  3. Compare with Trusted Sources: Cross-reference unfamiliar additives with EFSA or FDA databases.
  4. Set Dietary Preferences: Many apps allow you to filter out additives based on allergies, sensitivities, or lifestyle choices (vegan, halal, kosher, etc.).

Pro Tip: For parents and anyone with food sensitivities, scanning is far faster and more reliable than memorizing hundreds of E numbers.

US vs EU: Food Labeling Laws and E Numbers

Did you know that the same snack can have different labels—and even different ingredients—depending on where you buy it? Here’s how the US and EU compare:

US vs EU Food Labeling: E Numbers and Additives
Regulatory Body Labeling Requirement Example
FDA (United States) Lists chemical names (e.g., “Tartrazine”) No E number, just “Yellow 5” or “Tartrazine”
EFSA (European Union) Lists E numbers (e.g., “E102”) “E102 (Tartrazine)”
  • Allergen Disclosure: Both regions require allergens to be clearly listed, but the EU mandates more prominent labeling.
  • Color Additives: Some colorants banned in the EU are still allowed in the US3.
  • Transparency: EU labels often provide both the E number and the additive name, making it easier to identify.

For global shoppers or those ordering online, Food Scan Genius bridges this gap by translating and flagging additives, no matter where the product comes from.

Why E Numbers Matter for Food Sensitivities and Dietary Preferences

If you or your loved ones have allergies, ADHD, or follow a specific diet, E numbers can be a hidden minefield. Some additives are linked to hyperactivity in children2, while others may not be suitable for vegans, vegetarians, or those avoiding pork or alcohol-derived ingredients.

  • Vegetarian/Vegan: Some E numbers are animal-derived (e.g., E120 – cochineal from insects)
  • Religious Dietary Laws: Certain E numbers may not be halal or kosher
  • Allergies: Sulfites (E220–E228) can trigger asthma or allergic reactions

Food Scan Genius lets you set your preferences and instantly flags products that don’t fit your needs.

Recent News: The Spotlight on Food Additives

The conversation about food additives is heating up. In 2024, The New York Times reported on new US proposals to ban certain food dyes linked to behavioral issues in children. Meanwhile, BBC News highlighted the EU’s stricter stance on titanium dioxide (E171), now banned in Europe but still present in some US foods. CNN also covered parents’ growing concerns about hidden additives in school snacks.

These stories underscore the need for transparency and the value of tools like Food Scan Genius in making informed choices.
