Is Artificial Food Coloring Safe For Kids? Here’s What You Should Know.

Are food dyes harmful to kids? Does artificial coloring make kids hyperactive? Here are the facts you need to know!

Food dyes are controversial. Read on for the facts.

Has your kid ever had a blue-stained tongue from a lollipop or pink frosting-smeared lips? And have you ever felt a twinge of worry, wondering whether those bright, colorful dyes are harmless or harmful–especially after reading something scary about dyes online?

I used to feel that way too. Food dyes have long been controversial, and there’s still some debate, confusion, and misinformation around them. So I dug into the research to get the answers we all need.

What is artificial food coloring?

There are two kinds of colors added to foods and drinks:

  1. Synthetic food dyes are man-made colors, and they’ve been around in the food supply for more than 150 years. Nine synthetic dyes are approved to use in food by the FDA, but Red 40, Yellow 5, and Yellow 6 are the ones you’ll see on labels the most.
  2. Natural food colors are mostly derived from plants including vegetables and fruit, such as beet juice (red or pink) and turmeric (yellow).

How do you know whether a product contains dyes?

Check the ingredient list. All synthetic food dyes MUST be listed by name with color plus a number (such as “Red 3” or “Blue 2”). If the product contains natural colors, the list may say things like “paprika extract (color)”. Here’s the tricky but important part: If you only see “artificial colors” or “color added” on the ingredient list, that actually means it contains natural color–and in this case, “artificial” simply means color was added that wasn’t there originally.

Which foods have artificial food coloring?

Foods that are unnaturally colorful (think candy and vividly colored drinks) often contain synthetic dyes. But synthetic dyes can also be in some surprising places, like frozen waffles, pickles, salad dressing, vanilla cake frosting, and white marshmallows.

In the U.S., we take in more than five times the amount of synthetic food dye as we did in the 1950s. And kids consume a lot more food dyes than adults do. That makes sense, since so many “kid foods” are often made with dyes, like brightly colored cereal and fruit drinks. The dyed foods and drinks that kids consume the most, according to researchers, are:

  • Fruit-flavored drinks
  • Ice cream & ice pops
  • Fruit leathers/gummy fruit snacks
  • Soda
  • Frosting & baking decorations (like sprinkles)
  • Cereal
  • Yogurt

If you want to avoid medicine with dyes, look for “dye-free” or “free from dyes” on the package.

What about food dyes in medicine?

Even if you don’t buy foods with dyes, your child’s medicine may contain them. Dyes are typically added to make flavored medicines seem like the appropriate color (like a grape-flavored medicine that’s purple).

In a study published in Food and Chemical Toxicology, researchers measured the levels of food dyes in children’s supplements and medicines. They found that vitamins and tablets weren’t a significant source for dyes for kids. But pain reliever syrups and cough/cold/allergy syrups were–in some cases, at levels above the FDA’s “Acceptable Intake”.

In fact, they found that intake of Red No. 40 could be twice the Acceptable Intake for some pain relievers and three times the Acceptable Intake for some cough/cold/allergy syrups. So if you want to avoid dyes, read medicine labels, look for dye-free options for over-the-counter meds, and ask your pharmacist about prescription medicines.

Are food dyes really made from petroleum?!

Yes, but it’s not the same as ingesting crude oil–which is a common scare tactic you’ll see out there. It’s a lot more complicated than that. Petroleum is a rich source of carbon, hydrogen, and oxygen, so those molecules are extracted from petroleum, purified, and turned into powders or liquids to use in foods and drinks. It sounds like a crazy process, but other products you probably use regularly–like some vitamins, gum, and medicines–are made with these same molecules from petroleum.

Is artificial food coloring harmful?

The FDA says says that food dyes–like all the food additives they’ve approved–are safe. But the FDA does have a few cautions:

  • Yellow 5 can cause itching and hives for some people.
  • Carmine/cochineal extract, a red color made from insects, can cause an allergic reaction for some people. So this color, even though it’s a “natural” color, will always be specifically named in ingredient lists.
  • Synthetic dyes may affect some children’s behavior. The FDA says that while the evidence shows most kids have no adverse effects, some children may be sensitive to them.

The consumer advocacy group Center for Science in the Public Interest (CSPI) also claims that Yellow 5 and Yellow 6 (two of the most commonly used food dyes) may be contaminated with benzidine, a compound that’s linked to cancer. Though the FDA tests for benzidine, CSPI says the established safe limits aren’t appropriate for kids, who take in more dyes and have smaller bodies.

Do artificial food dyes make kids hyperactive?

For decades, researchers have been studying synthetic food dyes and children’s behavior. In the 1970s, pediatric allergist Ben Feingold developed an elimination diet for behavior and attention issues in kids that nixed dyes (plus other food additives like artificial sweeteners and certain preservatives) that some parents still use today.

Since then, some studies like these have shown possible links between dyes and behavior:

  • An analysis of studies in 2012 concluded that about eight percent of kids with ADHD have symptoms that are caused or worsened by dyes. Eight percent of all diagnosed kids in the U.S. works out to nearly a half million that could be affected by dyes.
  • A 2007 UK study found that a portion of young children (including those without an ADHD diagnosis) showed inattention, impulsivity, and hyperactivity within as little as one hour after drinking a dyed beverage. (This study was criticized by some because the drink also contained a preservative, which may have impacted kids too.)
  • A new report from the California EPA concluded that synthetic food dyes can lead to hyperactivity and other neurobehavioral problems like inattentiveness and restlessness in some children–and that children seem to vary in their sensitivity to food dyes.
Two bottles of juice, one red and one yellow, sit on a white countertop.
Sports drinks and fruit drinks often contain dyes.

Why are some kids sensitive to food dyes (and others aren’t)?

Nobody knows for sure, but researchers have come up with some theories:

  • Dyes might cause the release of histamine from cells, which can impact the brain.
  • Dyes might “leak” out of the gut and into the body (the general concept of a “leaky gut” is controversial).
  • Dyed foods tend to be more highly-processed, and kids might be reacting to an overall less nutritious, ultra-processed diet.

Colorful kids’ cereals often contain dyes.

How much dye is too much for kids?

Researchers say children in studies reacted the most to 50mg or more dye (though some kids did react to less). Here are amounts per serving in some common drinks (source: Amounts of artificial food colors in commonly consumed beverages and potential behavioral implications for consumption in children):

  • Country Time Pink Lemonade: 0.2 mg
  • Gatorade Lemon Lime: 3.4
  • Hawaiian Punch Green: 19 mg
  • Powerade Orange: 22.1 mg
  • Orange Crush: 33.6 mg
  • Sunny D Orange Strawberry: 41.9 mg

Here are amounts per serving in some common foods (source: Amounts of artificial food dyes and added sugars in foods and sweets commonly consumed by children):

  • Strawberry NutriGrain Bar: 2.5 mg
  • Fruit Gushers (1 pouch): 3.7 mg
  • Red Fla-vor-Ice ice pop: 3.8 mg
  • Coldstone Creamery Mint Ice Cream (1 scoop): 6.0 mg
  • Duncan Hines Red Velvet Cake Mix: 9.5 mg
  • Frosted Cherry PopTart: 10.1 mg
  • Jell-O Orange: 12.2 mg
  • Cheese & Peanut Butter Crackers (8 crackers): 14.4 mg
  • Fruit Loops: 14.6 mg
  • Fruity Pebbles: 19 mg
  • Red slushie (small): 22.4 mg
  • Strawberry Wafer Cookies (3): 24.2 mg
  • Skittles (1 package): 33.3 mg
  • Trix: 36.4 mg
  • Cap’n Crunch Oops All Berries: 41.3 mg

Aren’t these dyes banned in the EU?

No, but there are warning labels on products. The Food Standards Agency (the EU’s version of the FDA) started requiring warning labels in 2010 for any products with dyes. The warning label states: “‘May have an adverse effect on activity and attention in children”. A lot of companies switched to using natural colors (like beet juice and annatto) to avoid the warning labels.

In 2011, the FDA voted on whether to require those same warning labels in the U.S., but decided there wasn’t enough evidence (the vote was 8-6 against labels–by no means unanimous). The committee said that more research needs to be done on whether food dyes are safe for kids.

Why don’t all companies use natural colors?

Synthetic dyes are less expensive, easier to use, and give a more consistent color. Since natural colors come from plants, they have wider variation, and the colors tend to be less vivid and more subtle.

Four small white bowls contain frosting colored with natural food coloring in shades of pink, purple, yellow, and blue.
These vibrant frostings were made using natural food colors!

Should you avoid artificial food dyes?

Some parents choose to avoid additives like synthetic food dyes and artificial sweeteners, and that’s a valid choice. Dyes don’t serve any purpose in food except color–and more companies are changing over to plant-based colors because of consumer demand. So it’s easier than ever to find naturally colored versions of things like fruit-flavored yogurt.

If you’re wondering whether dyes affect your child’s behavior, eliminate them and see if you notice any difference. I’ve talked to parents who have noticed a change after avoiding dyes and others who haven’t.

Here’s what I do

Personally, I don’t tend to buy products that contain dyes since there are so many naturally-colored alternatives. But I don’t stress out about birthday cake at a party or an occasional ice cream cone either. If I thought my kids were sensitive to dyes, I would do things differently.

Should kids with ADHD avoid food dyes?

Some kids with ADHD might benefit from a dye-free diet. Others may not experience a difference. Read more about this: Is There a Diet for ADHD That Actually Works?

    Your “blue food” story sounds very similar to mine. In my case, my “aha moment” was a blue ring pop. My daughter sat down on bleachers at a baseball game with 2 other little girls – each had blue ring pops in hand. Within 5 mins. maybe less, my daughter was up and running at top speed in big giant circles around the area behind the bleachers. She was feral, unstoppable and had the deer in headlights look I had seen her have before. The other 2 girls just ate their ring pops totally unaffected. But my child went to another world within minutes. It all clicked then and there. I tested my theory with a blue dum-dum lollipop soon after, and sure enough my daughter began to run, bounce her head off the couch cushions repeatedly, ran room to room and was unstoppable…for a shorter duration. A similar thing happened with artificial reds. So I had my answer….why did my child act so crazy at parties while the other little kids sat calmly at the table to do their crafts? Why did my daughter sometimes appear to be so spaced out that she lost her ability to speak? She was high on artificial colors and I suspect there are sensitivities to GMO’s too. So we by and large keep these non-food additives out of our families diet and life is much better many years later.

    It troubles me still that so many parents put their kids on potentially toxic and harmful ADHD/ADD medications when the underlying cause may simply be the colored sprinkles on their cupcakes. Thanks for writing about this and educating others!! Hopefully more pediatricians will learn about this and suggest eliminating dyes first before medicating.

    PS: How could I forget that I have a much more recent “blue dye” episode to share?! This one came in the form of back-to-back blue G2 Gatorades after 2 separate baseball games.

    My son couldn’t even get half the bottle finished before having such a nosedive in energy that he curled up in a fetal position in a chair on the sidelines for about 30 mins. after the 1st episode. The second episode happened in the car post game – again about half the bottle was gone and he tanked physically and felt very sick and tired.

    I generally allow my kids to participate in whatever the rest of the kids are having for social reasons. My thinking is that because we eat relatively clean by and large 95% of the time, I will allow my stance on no artificial foods to take a backseat when social-acceptance and group participation is involved. All the junk that gets thrown at kids these days makes my heartbreak, but I allow it in my kids, and when they feel bad afterward it helps them see why we choose differently.

    These recent immediate reactions to Gatorade do have me wondering what is it about a supposed energy drink that is causing my kids to have negative energy to the point of having to lie down and “process” the toxins. I’m certain there has been Gatorade before without this immediate effect…maybe there has been a recent change in their formulation???

      Beth–my son had a similar reaction to Gatorade (don’t remember which color). I think he was mildly dehydrated and he drank it very quickly. Ended up sacked out on the couch feeling terrible. I chalked it up to drinking a sugary beverage too fast, but perhaps you’re right, it may have been a combination of factors/ingredients causing him to feel badly. As for ADHD, what troubles me is that there may be something in the food supply that is aggravating a problem for many kids. Attention problems are being diagnosed at such a high rate, why not eliminate this unnecessary food ingredient from the food supply? Even if it doesn’t help EVERY child with attention issues, it may help some.

    My whole problem with the US acceptance of food dyes is that it’s just not necessary. I get wanting to make some foods look a little more appealing (although I think we’ve conditioned our kids to think all “kid foods” need to be rainbow colored). But if it’s not necessary to use artificial dyes, why do we do it… and in SO many foods. (which IMO includes caramel coloring, another food nuisance)

    I’m in a unique position in that I’ve had my youngest tested for food sensitivities and intolerance because of his persistent allergies and asthma that didn’t respond to traditional antihistamines. And you know what we found one of his moderately reactive items was? Yellow #6. I know not every parent can/will go to the trouble to test to that level, but it just reinforces that beyond just ADHD, there are other ways in which our kids can have negative reactions (like inflammation, etc.,) to chemicals being added to food.

      Great point Regan. While a relationship with attention is the most researched of the effects, there are certainly many other ways dyes could impact kids. And I agree that dyes just aren’t necessary! Not all food has to be (unnaturally) brightly colored to be appealing.

    But look at how much less vibrant those European M&Ms are; our M&Ms need to scream their color don’t they? {kidding. totally kidding.}

    Thank you for your thorough research. I appreciate that others are out there bringing attention to this issue. Alternatives (to artificial dyes) ARE out there, removing them IS feasible. It’s time to rally the troops to demand some changes…and this is a great start!

    I want to chime in on what Regan said! As one of the parents interviewed for this article, I think it is really important to talk about how the reactions can go “beyond the ADHD” stuff. My son Patrick has reactions that range from the behavioral things mentioned in the article, to uncontrollable diarrhea, skin rashes, and night terrors that can last for up to 72 hours after a dye exposure. He’s simply not a well child when he eats food dyes — or when he has his face painted, uses heavily colored/scented soaps and lotions, gets a temporary tattoo, etc. It’s a topical issue as well as an ingestion issue for us. Very scary, very potent, and I would add that he’s now, as a dye-free child, not even CLOSE to any spectrum of needing evaluation or diagnosis for ADHD or any other emotional/behavioral issue. He’s on “green light” at Pre-K every day, no problem. So it really goes far beyond the traditional thinking that dyes are a problem for ADHD kids and the rest of our kids are fine. They’re not fine at all.

    Sally, just read your article & this is fascinating! Maybe I’ve been in a cave on this one, but I had no idea that there is both double-blind research & anecdotal evidence to support a potential link between artificial dyes and hyperactivity. I think the number of kids on ADHD meds, without sufficient understanding of how those meds affect developing minds, is a huge concern right now, and it’s pretty wild to think that taking away artificial dyes (which are pretty much unnecessary anyway!) could influence those disturbing statistics.
