Each year, UBC dietetics students have a class project where they practice writing nutrition articles for the public. This year, I asked students Mei Ho and May Hasegawa to research are food dyes safe for kids. Here’s what they found ~ Kristen
When you are shopping for snacks for your child, do the bright colours make you think twice about about adding it to your basket? Many foods we come across in our everyday lives have colour added in order to make it appear more appetizing. It is very common to see vivid colours in foods and beverages marketed towards children, such as candies, desserts and chewing gums. Foods can be coloured by natural food dyes like caramel colouring, or artificial food dyes, which are colours made from petroleum1. Today we will be looking at food dyes in the context of artificial food dyes, which have been used more commonly in foods in recent years.
Are Artificial Food Dyes Safe for Kids?
As early as the 80’s, researchers began to study the effects of artificial food dyes on children’s health. The results of their studies have been controversial, and has stirred concern amongst consumers. Some have suggested a possible link between artificial food dyes and hypersensitivity in children3. Others have researched possible risks of organ damage, cancer, birth defects and allergic reactions1. While no study findings have been conclusive, countries in Europe such as the U.K. have banned artificial food dyes altogether for safety measures1.
What Are the Safety Regulations of Food Dyes in Canada?
Regulations in North America state that there is not enough scientific evidence to say artificial food dyes cause negative effects on children’s health3. Canada permits the use of food dyes in everyday foods from bread, butter, milk to cheese. All food dyes must first be approved by our federal regulatory body, the Canadian Food Inspection Agency (CFIA). At this time, Canada has approved ten dye colours for use in food and beverages.
However, it has not been ruled out that food dyes may affect children with attention-deficit/hyperactivity disorder (ADHD) and behavioural problems differently3. Researchers agree that more research on artificial food dyes is required.
Food Dyes Across the Globe
In 2009, the U.K. imposed strict regulations to remove certain food dyes from foods and beverages. This prompts us to think, why hasn’t North America followed along? It is interesting to note the different approaches used by North America and the U.K. when it comes to ensuring public safety through foods.4
- North America: tries to find the strongest evidence available before implementing new regulations.
- UK: uses a more precautionary approach, meaning that it will take action to protect the public even if the evidence is not entirely conclusive.
Moving Forward: What Can You Do?
With all this information, it can be confusing to decide whether you want your children to be consuming artificial food dyes. It may first be helpful to understand how to identify whether something contains artificial food dyes. By law, companies are required to list the name of the dye on the ingredient label. It may be tricky for shoppers to recognize the commercial names of artificial food dyes. Here are the names of 10 common artificial food dyes in Canada:5
- Allura red
- Brilliant blue FCF
- Citrus Red No.2
- Sunset yellow FCF
- Fast green FCF
- Erythrosine Red
- Amaranth Red
- Ponceau SX
There are also ways to add colour into your cooking at home without using food dyes! Kids are drawn to bright colours, and baking at home can be more fun if your child has the chance to make their own colours. This can be done by boiling, blending, and/or pureeing vegetables or fruits for their natural colours.6
- Raspberries, pomegranate and beets – pink/purple
- Carrots – orange
- Turmeric powder – yellow
- Blueberry – blue
- Spinach – green
- Red cabbage – purple and blue
- For purple, boil cabbage in hot water until water is dark purple colour
- For blue, slowly add some baking soda to purple water
Are Food Dyes Safe for Kids – May’s Opinion:
While there is not enough evidence to conclude that artificial food dyes are harmful to our body, I feel that more research is needed to fully understand their effects on our health. I like to refrain from using artificial food colouring in my own baking, and opt for more natural options like using juice from fruits or vegetables.
Are Food Dyes Safe for Kids – Mei’s Opinion:
As the research is inconclusive, it is ultimately up to the consumers to make an informed decision. New food labelling requirements in Canada will now include the commercial names of synthetic food dyes in the ingredient list, but it is questionable whether or not consumers will recognize these names or be able to associate them with food dyes.
Are Food Dyes Safe for Kids – Kristen’s Opinion:
Call me conservative, but I am suspicious of foods that are highly processed. My motto is “foods closest to the way nature made them are the healthiest choice”. Artificial food dyes are about as far from nature-made as you can get. So, I would recommend steering clear of artificial food dyes for day-to-day eating. But I’m also practical. Our bodies are amazingly adaptive. Eating foods with artificial dyes once in a while is likely not going to cause harm. So if your child is invited to a birthday party where they serve cake with bright green icing, let your child enjoy the cake right along with the other kiddos.
If your child has behaviour concerns, such as ADD/ ADHD, I think it’s worth doing a food trial where you eliminate all food dyes and see how your child’s behaviour responds. There may be no effect. Or, your child may be a member of the sub-set of kids who have a link between behaviour and food dyes.
