Red Dye 3, also known as FD&C Red No. 3 or erythrosine, has been a topic of considerable debate in food safety circles for decades. Originally approved for use in food products since 1907, this synthetic dye derived from petroleum has been both lauded for its vibrant color and criticized for potential health risks. Here, we delve into the common foods where Red Dye 3 might be lurking, often unexpectedly, and explore the controversy surrounding its use.
What is Red Dye 3?
Red Dye 3 is a bright cherry-red coloring agent used in a variety of consumables. It was banned from use in cosmetics in 1990 by the FDA due to studies showing it caused cancer in lab animals, specifically thyroid cancer in rats. However, despite this ban in cosmetics, Red Dye 3 continues to be approved for use in food, dietary supplements, and oral medications in the United States, sparking ongoing debate about its safety for human consumption.
Common Foods Containing Red Dye 3
1. Candies and Confections:
- Most notably, Red Dye 3 is found in candies like conversation hearts from brands like Brach’s and Spangler, where it enhances the bright, festive colors. Other candies such as jelly beans, licorice, and gumdrops might also contain this dye to achieve their vivid red hues.
2. Baked Goods:
- Pastries and baked goods, particularly those with red icing or fillings, can contain Red Dye 3. Think of holiday-themed cakes or strawberry-flavored pastries where the color needs to pop.
3. Beverages:
- Certain flavored drinks, especially those with a strawberry or cherry essence, might use Red Dye 3. This includes some sodas, fruit-flavored drinks, and surprisingly, even some nutrition shakes like strawberry-flavored Nesquik or Pediasure.
4. Snack Foods:
- This dye can be found in snack foods where color is meant to enhance appeal, like certain flavors of chips or popcorn that have a 'red' theme, such as barbecue or spicy flavors.
5. Breakfast Cereals:
- Some cereals aimed at children, which are often brightly colored to attract young consumers, might use Red Dye 3. Cereals with red fruit shapes or red-colored marshmallows are potential candidates.
6. Medications and Supplements:
- Red Dye 3 can also be an ingredient in medications, particularly in chewable tablets, syrups, or gummy vitamins. An ironic twist is its presence in medications like Vyvanse, used to treat ADHD, while some studies suggest a link between Red Dye 3 and hyperactivity in children.
7. Dairy Products:
- Flavored yogurts, especially those with fruit bits or red fruit flavors, may include this dye to make them more visually appealing.
Health Concerns and Controversies
The use of Red Dye 3 in food has not been without controversy. Here are some key points:
- Cancer Risk: The primary concern stems from the 1990 studies where high doses of Red Dye 3 were shown to cause thyroid cancer in animals, leading to its ban in cosmetics. Despite this, the FDA has maintained that the dye is safe for ingestion at current usage levels.
- Behavioral Issues in Children: There's growing concern about the impact of artificial dyes, including Red Dye 3, on children's behavior. Some research suggests a link between these dyes and hyperactivity or attention deficits, although the evidence is not universally accepted.
- Regulatory Discrepancies: While banned in many countries for food use, the U.S. still allows it, creating a regulatory inconsistency that has puzzled consumers and health advocates alike.
- Consumer Advocacy: Groups like the Center for Science in the Public Interest (CSPI) have been pushing for a ban on Red Dye 3 in food, highlighting the Delaney Clause, which prohibits FDA approval of any food additive found to cause cancer in humans or animals.
Moving Forward
- Legislative Action: California has taken steps by passing a law in 2023 to ban Red Dye 3 in food by 2027, signaling a potential shift in how these additives are viewed.
- Industry Response: Some food manufacturers have started removing synthetic dyes from their products, opting for natural alternatives like beet juice or paprika, though these can be more costly and less vibrant.
- Consumer Awareness: The key for consumers is awareness. Checking labels for "FD&C Red No. 3," "erythrosine," or "Red 3" can help in avoiding this dye if one chooses to do so.
- Research Continuation: Ongoing research might influence future regulations, particularly if new evidence strengthens the case against Red Dye 3.
Conclusion
While Red Dye 3 adds a splash of color to our foods, the health implications continue to be a point of contention. With increased scrutiny from both the public and regulatory bodies, the future of this dye in our food system remains uncertain. Consumers are becoming more vigilant about what they eat, and this might lead to broader changes in food coloring practices. Until then, understanding the presence of Red Dye 3 in everyday foods is crucial for making informed choices.
