Unmasking Green Dyes: Fast Green FCF and Green S

Two common artificial green dyes used in the food industry are Fast Green FCF (also known as FD&C Green No. 3 or E143) and Green S (known as E142). Their vibrant hues are often used to make products more visually appealing, but these chemical additives are not without their potential risks.

Decoding Ingredient Lists

Ingredient lists on food packaging can sometimes resemble complex chemical equations, making them challenging to decode. In the case of green dyes, they may be listed under a variety of names. Fast Green FCF may be listed as FD&C Green No. 3, Food Green 3, or E143. Meanwhile, Green S could be referred to as E142.

The key to identifying these dyes is understanding the different naming systems. In the United States, FD&C refers to the Federal Food, Drug, and Cosmetic Act, which authorizes these dyes for use in foods, drugs, and cosmetics. In Europe, the E number system is used, with E143 and E142 referring to Fast Green FCF and Green S, respectively.

Inquiring in Restaurants

While it’s easier to identify these additives in prepackaged foods, it becomes trickier when dining out. However, you can still make informed choices by asking direct questions to the restaurant staff. Don’t hesitate to ask if they use artificial food coloring in their dishes. For instance, you could ask, “Do you use any artificial dyes in your food, specifically green dyes such as Fast Green FCF or Green S?”

While not all staff may know this information offhand, they should be able to check with the kitchen or provide ingredient information upon request.


Navigating the world of food additives can be daunting, especially when prioritizing the health and wellbeing of your children. Armed with the right knowledge, you can confidently interpret ingredient lists and make informed inquiries in restaurants, ensuring that the foods your family consumes align with your values of honesty, integrity, and sustainability.
