The Ubiquitous Presence of Red Dye 40
Red Dye 40, also known as Allura Red AC, FD&C Red No. 40, or E129, is a synthetic food coloring derived from petroleum. It is one of the most widely used artificial dyes in the United States, prized by manufacturers for its vibrant, stable, and cost-effective coloring properties. However, its widespread use makes it a challenge to avoid, as it is found in a vast array of processed foods and beverages, often in products that don't appear red at all.

Reading Labels: How to Find Red Dye 40
Since Red Dye 40 can appear in unexpected places, reading ingredient labels is the most effective strategy for avoiding it. Look for the following names on the ingredient list:
- Red 40
- FD&C Red No. 40
- Red No. 40 Aluminum Lake
- Allura Red AC
- C.I. 16035
- E129
It's important to remember that ingredients are listed by weight, so the higher up the dye appears on the list, the higher its concentration. Also, note that some brands, particularly those sold in Europe, use natural alternatives for their products, so a product from a U.S. brand might be different from its European counterpart.
Health Concerns and Regulations Surrounding Red Dye 40
The safety of Red Dye 40 has been a subject of extensive debate and research for decades. While regulatory bodies like the U.S. Food and Drug Administration (FDA) have historically maintained that it is safe within approved limits, some studies suggest potential health concerns.
- Hyperactivity in Children: Multiple studies, including the 2007 Southampton study, have found an association between artificial food dyes, including Red 40, and increased hyperactivity in children, particularly those with ADHD.
- Inflammation and Gut Health: Recent animal studies have shown that Red 40 may cause inflammation in the colon and disrupt the gut microbiome.
- Allergic Reactions: Although rare, some individuals experience allergic reactions, such as hives or swelling, after consuming Red 40.
- DNA Damage: Research has raised concerns about the potential for Red 40 to cause DNA damage.
In response to these concerns, regulations vary globally. The European Union requires a warning label on products containing Red Dye 40, stating it “may have an adverse effect on activity and attention in children”. The U.S. has seen regulatory shifts, with Red Dye 3 being banned in 2025 due to cancer concerns, prompting discussions about Red Dye 40, though it remains approved.
