Avoiding Artificial Colors in Food: A Practical Guide
Artificial food dyes are added to make products look more appealing. They serve no nutritional purpose. If you want to reduce your exposure, knowing the names and where they hide makes it straightforward.
The Most Common Artificial Dyes
The most widely used synthetic dyes in the US are Red 40 (Allura Red, E129), Yellow 5 (Tartrazine, E102), Yellow 6 (Sunset Yellow, E110), Blue 1 (Brilliant Blue, E133), Blue 2 (Indigo Carmine, E132), Red 3 (Erythrosine, E127), and Green 3 (Fast Green, E143). In the EU, products containing Yellow 5, Yellow 6, Red 40, Blue 1, Blue 2, or Green 3 must carry the warning 'may have an adverse effect on activity and attention in children'.
Where Artificial Dyes Are Most Common
Artificial dyes appear most frequently in: candy and gummy snacks, fruit-flavored drinks and sodas, breakfast cereals, flavored chips and crackers, ice cream and frozen desserts, maraschino cherries, and some medications and vitamins. They are less common in plain dairy, plain meats, plain grains, and most fresh produce.
How to Spot Them on a Label
Look for the dye name followed by a number (Red 40, Yellow 5) or the E-number (E129, E102). In the US, certified color additives must be listed by their specific name. In the EU, they appear as E-numbers. A product with a bright, unnatural color — vivid orange, electric blue, neon green — almost certainly contains artificial dyes. Natural colorants like beet juice, turmeric, and spirulina are alternatives used in some products.
Natural Colorants to Look For
Some manufacturers use natural colorants instead of synthetic dyes. Common natural colorants include: beet juice or beet powder (red/pink), turmeric (yellow), spirulina (blue/green), annatto (orange/yellow), paprika extract (red/orange), and carrot juice (orange). These are generally considered less controversial than synthetic dyes, though some people are sensitive to annatto.
Frequently Asked Questions
- Are artificial food dyes banned in Europe?
- Most synthetic dyes used in the US are permitted in the EU but require a warning label stating 'may have an adverse effect on activity and attention in children.' Red 3 (E127) was revoked by the FDA in 2025 for use in food. Some dyes permitted in the US are restricted or banned in other countries.
- How do I avoid artificial dyes when eating out?
- When eating out, ask about ingredients in brightly colored dishes, sauces, and desserts. At home, check labels on condiments, sauces, and drinks. BioBrief can scan packaged products to flag artificial dyes before you buy.
