If you’ve eaten many processed foods or candy, then you have most likely had Red Dye 40.
Red Dye 40, also known as Allura Red AC, is a synthetic color additive made from petroleum. It is found in many processed foods as a coloring for candies, sauces, dressings, beverages, icings, jellies, spices, gelatin products, baked goods, and frozen goods. And may also be found in some cosmetics and medications.
It has been approved by the FDA and deemed as “safe for public consumption”.
And while it may be “safe” for some, many studies have linked it to a number of health problems including migraines, hyperactivity in children, and allergies. And there have been traces of Benzene found in the dye, which is a known carcinogen.
Due to the many possible side effects, The European Union (EU) requires that any products containing Red Dye 40 must also include a warning label that states “May have an adverse effect on activity and attention in children.”
To better understand the risks and dangers associated with Red Dye 40, let’s take a look at some of the most serious side effects.
1. Hyperactivity and ADHD in Children
Perhaps the most talked about side effect is that of hyperactivity in children. Multiple studies demonstrate that children with ADD/ADHD may be severely affected by artificial food colorings, causing an increase or trigger in negative behavior. While other research seems to indicate that artificial colors, as well as sodium benzoate, can cause some non-ADD/ADHD children to have increased hyperactivity.
2. Migraines and Allergic Reactions
Artificial additives and food colorings may disrupt neurochemical balances in the brain which can contribute to the development of migraines.
Allergic reactions to food colorings can manifest themselves in various symptoms including:
- Hives
- Swelling (in severe cases it can lead to anaphylactic shock)
- Itching and Rashes
- Respiratory problems (difficulty breathing and wheezing)
- Headache
- Dizziness
- Gastrointestinal Issues
- Persistent Cold or Flu-like Symptoms
3. Gut Inflammation and Cancer
Several studies have shown a correlation between Red Dye 40 and Intestinal Inflammation. One study in particular found that Red 40 caused colonic inflammation, DNA damage, and a decrease of beneficial gut bacteria while increasing harmful gut bacteria in the microbiome.
Red 40, along with Yellow 5 and Yellow 6, has been found to be contaminated by Benzidine or other carcinogens.
Benzidine is a manufactured chemical that was used to produce dyes for cloth, leather, and paper. In 1973 OSHA regulations banned US production of Benzidine. However, some Benzidine-based dyes may still be imported into the United States. And some dyes used to color food or drinks may contain impurities that can be broken down to Benzidine once inside the body.
Benzidine has been linked to multiple forms of cancer, with bladder cancer being the most common.
With so many risks associated with Red Dye 40, the question should be asked “Why is it still being used in products?”
Why are so many companies willing to overlook (at best) these potential side effects for a color additive? The answer is that it makes the food and drinks appear brighter and more appealing. Thus raising sales.
However, if we are educated on the potential health risks associated with Red Dye 40 we at least can make an informed decision.
My purpose for this post is simply to present the possible health risks so that, regardless of what you choose, you are able to make an informed decision.
As always, I encourage you to do your own research and come to your own conclusion.
