1. What is Red Dye 3 and Why Was it Used in Foods?
Red Dye 3, scientifically known as erythrosine, is a synthetic coloring derived from petroleum. It imparts a bright, cherry-red hue to foods and beverages, enhancing their visual appeal. The FDA initially approved it in 1907, before extensive research on food additives was standard.
To put it in perspective, this was at a time when the negative effects of smoking were unknown and cigarettes were even endorsed by doctors.
1.1. Historical Context: The Approval and Re-evaluation of Red Dye 3
In 1960, the FDA introduced the Color Additive Amendments, prompted by “serious adverse effects” linked to various color additives. This amendment provisionally approved red dye 3 along with approximately 200 other color additives, allowing their temporary use until conclusive scientific data established their safety or potential harm.
In 1969, Red Dye 3 was unconditionally approved for use in food and ingestible medications. However, in 1990, the FDA banned its use in cosmetics following lab animal research that invoked the Delaney Clause. The Delaney Clause mandates the FDA to prohibit food additives found to cause or induce cancer in humans or animals, as indicated by testing. Despite the FDA’s stated intention to ban Red Dye 3 in food and drugs, it took over 30 years and a 2022 color additive petition for the agency to act again.
1.2. Health Concerns and Research Findings on Erythrosine
Recent studies indicate that red dye 3 is linked to hyperactivity in children and, in high doses, can cause thyroid cancer in male rats. While human studies haven’t confirmed thyroid cancer, the FDA now classifies red dye 3 as an animal carcinogen. The European Food Safety Authority (EFSA) has also re-evaluated the safety of erythrosine, considering potential risks to human health, particularly for children.
According to research from the University of California, Berkeley, food dyes, including Red Dye 3, may contribute to behavioral issues in children. The study suggests a link between artificial food coloring and increased hyperactivity.
