Currently, research is raising more and more concerns regarding red dye 40 and other artificial food colors.
The National Institute of Health (NIH) believes that current scientific research is “too substantial to dismiss,” but more research into red dye 40 needs to be conducted to understand its effects fully.
This post contains:
- What we currently know about red dye 40 and other artificial food colors
- How it affects children’s behavior, particularly those with an ADHD diagnosis
- Which popular foods contain red dye 40.
- Which foods are safe to eat
What is Red Dye 40?
Red Dye 40, also known asAllura Red AC, is a synthetic food dye that belongs to theazo dye class. It is one of the most commonly used food dyes in the United States and many other parts of the world.
Red Dye 40 comes from coal tars. Coal tar is athick dark liquid by-product of burning coal(like during the production of petroleum products).
Dyes made from coal tars are created by mixing various fragrant-smelling hydrocarbons likebenzyne and toluene.
Benezynes aresweet-smelling chemicalsderived from natural gases andcrude oil.Toluene is a solvent used in paints, lacquers, thinners, glues, correction fluid, and nail polish remover.
Uses for Red Dye 40:
Red Dye 40 is water-soluble, making it very versatile for use in a range of products.
Manufacturers use this artificial food color to give a bright, attractive red color to various food products, beverages, candies, cosmetics, and even some medications.
However, it’s also known to turn up in less surprising places—for example, chocolate pudding.
Although the US Food and Drug Administration (FDA) has deemed it safe for use in food within specified limits,Norway, Finland, France, Austria, the UK,and several other European countries havebanned Red Dye 40due to the growing evidence of its harmfulness.
Research Findings on Red Dye 40: Harmful Effects on DNA, Gut Health and Behavior in Children
Current research into the safety and potentially harmful effects of Red Dye 40 has produced findings that raise concerns about its impact on health.
Doctors have theorized since the 1920s that red dye and other artificial food colors could affect child behavior. But, no real research was conducted until pediatric allergist Dr. Benjamin Feingold presented the findings from his patients in 1973.
Since 1965, he’d been having his patients with ADHD follow a special diet that contained no artificial food colors. At the time,he claimed that 60-70% of his patients no longer met the diagnostic threshold for ADHD once they changed their diet.
So, what was going on with his patients? Research shows thatconsuming red dye 40 affects the metabolism of other nutrients and affects brain functioningwithout crossing the blood-brain barrier. (Source)
A study published in 2023 has indicated that Red Dye 40 can causeDNA damage, contribute tocolonic inflammation, and negatively affectthe microbiome. The research highlights the potential role of Red Dye 40 in developing early-onset colorectal cancer (EOCRC), given its prevalence in ultra-processed and pro-inflammatory foods, which are particularly appealing to children.

Also, Red 40 containsp-Cresidine, which the USDepartment of Health and Human Servicessays is“reasonably anticipated”to be classified as ahuman carcinogen.

Artificial Food Colors Don’t Cause ADHD – They Cause Pediatric Hyperactivity, Learning Challenges & Harms Gut Health
The research isn’t suggesting that artificial food colors like red dye 40 are causing ADHD. It’s believed that red dye and other artificial food colors cause pediatric hyperactivity and learning issues.
ADHD is a quantitative diagnosis. So, for some children, the effects of red dye can push them over the threshold for an ADHD diagnosis. Artificial food colors can also exacerbate ADHD symptoms, so symptoms become more manageable once they are eliminated from a child’s diet.
Consumption of red dye 40 has quadrupled in the last 50 years.
Additionally, research shows red dye 40 alters the composition of microorganisms in the gut, leading to increased susceptibility to inflammation (Source). It also dysregulates serotonin production in the gut.
Serotonin is a key neurotransmitter that, while commonly associated with brain function, is predominantly produced in the gut. It plays a crucial role in regulating mood, appetite, and digestion.

Are you Canadian?
Fortunately, in the United States, companies are required under the FDA to label dyes used under the list of ingredients.
However, regulations are a little more relaxed in Canada. In Canada, they simply need to report “colours”. So, if you’re in Canada, you should check your labels and avoid anything containing artificial colors.
Safe Foods
So what’s safe to eat? When grocery shopping – look for foods that are marked “no artificial flavors or colors”, or “Organic”.
Some safe foods:
