With Red Dye 3 recently banned, many people are asking: why was it banned, and are other artificial food dyes just as harmful? The reality is that Red 3 is only one of several synthetic dyes linked to potential health risks. Other dyes, including Red 40, Yellow 5, and Blue 1, have also raised concerns due to their potential effects on health, particularly in children.

Understanding Artificial Food Dyes
Artificial food dyes are synthetic chemicals used to enhance the color of food, beverages, medications, and cosmetics. Studies have linked many of these dyes to various health issues, including hyperactivity in children, allergic reactions, and even cancer in lab animals.
At Trash Panda, we believe you deserve to know exactly what’s in your food, where it comes from, and how it may affect your health. Our app helps you decode ingredient lists, so you can make informed choices and swap out harmful products for safer alternatives.
Red 3: What You Need to Know
Red 3, also known as Erythrosine, is a synthetic dye made primarily from iodine and petroleum. Research has shown that this dye causes cancer in male lab rats, triggers inflammation, and disrupts thyroid function. Due to these findings, the FDA has finally banned Red 3 in foods and ingested drugs, though manufacturers have two years to phase it out.
Despite this ban, products containing Red 3 may still be on store shelves during the transition period. Common sources include:
Candy
Frostings and icings
Baked goods
Medications
To ensure you’re avoiding this harmful additive, use the Trash Panda app to scan ingredient lists before purchasing.
Red 40: Another Controversial Dye
Red 40 is one of the most widely used synthetic dyes, appearing in everything from cereals and candies to sodas and condiments. Despite being legal, it has been linked to many of the same health concerns as Red 3. The dye contains benzidine, a known carcinogen, albeit in amounts deemed safe by the FDA.
Some reported side effects of Red 40 include:
Hyperactivity and increased risk for ADHD
Behavioral changes
Allergy-like reactions
Skin irritation
Migraines
Depression
Dizziness
Respiratory issues
Digestive discomfort
Yellow 5: Linked to Allergies and Hyperactivity
Yellow 5 is a widely used dye in soft drinks, chips, and processed snacks. Studies suggest that it may contribute to:
Increased hyperactivity in children
Allergic reactions, particularly in those sensitive to aspirin
Potential DNA damage in lab animals
Some countries require warning labels on products containing Yellow 5, yet it remains legal in the U.S.
Blue 1: Potential Neurological Effects
Blue 1 is commonly found in sports drinks, ice cream, and baked goods. While it has not been as strongly linked to cancer as Red 3, studies indicate it may cross the blood-brain barrier, potentially affecting neurological function. Some side effects include:
Hyperactivity
Allergic reactions
Cellular toxicity in lab studies
How to Avoid Harmful Food Dyes
The best way to protect yourself and your family is by reading ingredient labels carefully. If you see any of the dyes mentioned above, consider choosing an alternative with natural coloring agents such as beet juice, turmeric, or spirulina extract. The Trash Panda app makes this process easier by allowing you to scan products and instantly identify harmful ingredients.
The Bottom Line
While the ban on Red 3 is a step in the right direction, many other artificial dyes remain in our food supply, despite growing health concerns. By staying informed and using tools like Trash Panda, you can take control of what you consume and make healthier choices for you and your family.
