For many of us, food coloring is just…there. It makes our candy brighter, our sports drinks more vibrant, and our baked goods a little more visually appealing. But behind that pop of color lies chemistry, and sometimes, a little controversy. Red Dye No. 3, a synthetic food coloring, definitely falls into the latter category. It’s been a bit of a rollercoaster ride for this particular dye, and even though it’s recently been banned in California, Nevada, and Washington, understanding what it was in and where it might still linger is crucial for conscious consumers.
So, what’s the big deal with Red Dye No. 3? Well, back in the day, way back in the 1990s (feel old yet?), the FDA actually banned it for use in cosmetics and externally applied drugs. This didn’t mean it disappeared completely. It was allowed to remain in food products, despite studies suggesting a link to cancer, particularly thyroid tumors, in laboratory animals. It’s the type of situation many found frustrating since we’re talking about something we put inside our bodies.

The thing with artificial colors (and Red Dye No. 3 isn’t alone in this drama) is that they don’t really add anything nutritionally. They’re purely for aesthetics. No extra vitamins, no bonus minerals, just a splash of color. And while some folks might argue that appealing colors make food more enticing (and therefore, you might eat a wider variety – we’ve all heard it, eat with your eyes!), we need to be aware of the potential trade-offs, especially when some colors, like Red Dye No. 3, carry baggage.
Okay, So Where Did Red Dye No. 3 Hide?
That’s the million-dollar question, right? The answer isn’t always very straightforward because it was used in a wide variety of products, sometimes in very small amounts. But here’s a general idea of where you were most likely to encounter it:
- Candies: This is probably the most notorious category. Think those bright red hard candies, gummy treats, and even some chocolate-covered candies. Red Dye No. 3 was often used to achieve that super-vibrant red and pink hue. If you have kids, you’ve probably seen this dye firsthand in their treats.
- Baked Goods: While not as common as in candies, Red Dye No. 3 could be found in some commercially made baked goods, like cakes, frostings, and even some types of bread. It’s not usually the main coloring, but it could be part of a blend. Pay close attention to the ingredient list if you regularly buy pre-made baked goods.
- Snacks: Yep, those seemingly harmless snacks might have been harboring a little Red Dye No. 3. Some flavored chips, crackers, and even popcorn could contain it. The key here is always reading the labels, because these categories are incredibly diverse in their ingredients.
- Processed Foods: It wouldn’t be a complete list without including the wide umbrella of “processed foods.” This category is so broad, and it’s where sneaky amounts of artificial colorings often hide. We’re talking things like sauces, jams, jellies, some breakfast cereals, and even certain types of pickles.
- Drinks: While not as prevalent as in other categories, Red Dye No. 3 could occasionally pop up in things like flavored sports drinks, fruit punches, and even some sodas.
- Medications: This is important to note because in some cases, colorings are used in medications (mostly children’s) for identification or palatability. Red Dye No. 3 was still in use in some medications for a time, making it imperative to be aware even outside of food.

The Ban and What It Means
Now, the good news. After years of concern, and recent pushes from groups like the Environmental Working Group, Red Dye No. 3 is finally seeing wider movement towards banishment in food, starting with the big three of California, Nevada and Washington. This is a huge victory for consumer health advocates, who have been saying the same thing for years- the potential risks weren’t worth it.

What Does It Mean for You?
For the average person, this likely means you may see some slight changes in the recipes and appearances of some of your favorite products. The food industry will start looking for replacements for that vibrant red hue. Here’s what we can all do:
- Read Labels: This is the single most important thing. Get into the habit of scanning those ingredient lists, not just looking at the nutrition facts. Look for “Red Dye No. 3” or sometimes it may be listed as “Erythrosine” which is another name for it. It’s also a good idea to just be aware of “artificial colors” in general.
- Choose Natural Alternatives: When possible, opt for foods that use natural colorings, like beet juice for reds, turmeric for yellows, or spirulina for blues and greens. There are more and more options available that use natural sources for coloration.
- Support Companies You Trust: Look for brands that are transparent about their ingredients and committed to using natural ingredients whenever possible, and reward them with your business.
- Be Patient: Change takes time, especially in the food industry. Don’t be surprised if some products still have the dye for a little while as companies phase out old inventory and switch to new formulations.

Final Thoughts
The story of Red Dye No. 3 is a great example of how important it is to be a mindful consumer. It highlights the complexities behind the ingredients we often take for granted. Learning about these things isn’t scary, it’s empowering. We have the right to know what’s in our food, and we have the ability to make informed choices. Now that Red Dye No. 3 is getting its well-deserved boot, hopefully we’ll see more focus on natural alternatives and a push for safer, healthier options across the board. So next time you grab a bright red treat, take a quick peek at that label. Your body will thank you for it!
