Are food and behavior connected? Some say that’s nonsense, that food has nothing to do with behavior.
Others say that there is a clear connection. What does the evidence show?
Food and behavior is abig topic these days. Folks are talking about gluten-free diets, paleo diets, candida diets, and more.
Does it all matter? Does food affect things like autism, ADD, ADHD and just plain old defiance?
So many behavioral issues can be traced to gut health. We need to all inform and empower parents to make a difference in their children’s (and their own) lives.}
It’s common to joke about kids being on a sugar high after a party, so all of us know, on some level, that food influences how kids behave.
But how many of us realize the extent to which our children’s day-to-day actions are shaped and molded by the foods we feed them?

Food and Behavior
An experiment on the effects of food on behavior done by the British TV series, The Food Hospital, produced shocking results. Party food loaded with sugar, artificial coloring, and other additives have the power to turn your lovely, cooperative child into a badly behaved, physically aggressive youngster.
Before we get to the study, let’s talk about some of the WORST things that you (and your kids) can eat.
Three Food Ingredients that Might Affect Behavior Negatively
1. Artificial Coloring
There’s evidence both for and against artificial food coloring causing behavioral issues in children.
More and more evidence is pointing to artificial food dyes as a major cause of ADHD in children. While this hasn’t been proven beyond a shadow of a doubt, the facts are strong enough to convince many European countries to ban blue 1 (brilliant blue), blue 2 (indigo carmine), yellow 5 (tartrazine), and yellow 6 (sunset yellow) among others.
These food colors have FDA approval and are found in cereal, candy, and a variety of colorful foods popular with children.
2. Sugar
There is a shocking amount of sugar in processed foods – and some of it is lurking in places you wouldn’t suspect. One 12 oz. can of co*ke has 9 ½ teaspoons of sugar. The same amount of Tropicana Farmstand Juice has 9 teaspoons. There’s also lots of sugar in flavored yogurts and chocolate milk – not so surprising. But did you know that there is often sugar in savory foods, such as ketchup, bread, sausages, and barbeque sauce? Your child can consume a considerable amount of sugar even before you let him or her eat candy, and high sugar levels contribute to hyperactivity.
3. Sodium benzoate
Sodium benzoate is a preservative found in carbonated beverages and fruit juices, condiments, candies and many other products. It has been implicated either separately or together with artificial colorings for causing or aggravating ADHD symptoms, and is best avoided.
It has also been noted that sodium benzoate reacts with citric acid to make benzene. So be very very careful with any foods or personal care products that have both ingredients together!
Read labels.
A real-food, nutrient-dense paleo diet – which excludes these three substances as well as anything likely to affect behavior – seems to be the best way to ensure your kids get the right nutrition.
How Does This Affect Your Family
You may think that these problems don’t affect you since your child doesn’t suffer from serious behavioral problems or learning disabilities. Remember, the children in the video were just a regular group of school kids–not children selected because they didn’t behave well. The impact on them was profound, so clearly, this is a concern for every parent.
Let’s do all we can to set our kids up for success.
The Food and Behavior Experiment
Children in Britain aged 5 – 9 attended a party.
They were split into two groups:
Group One: was fed healthy options such as apple slices, carrot sticks, sandwiches, hummus, etc. and was given water to drink.
Group Two: received the usual party fair: candy, potato chips, and soda (or as they say in the UK, sweets, crisps, and fizzy pop), all containing loads of sugar, artificial coloring, and other additives.
The children’s ability to follow instructions, concentrate and remember information was then measured as they played party games, and their actions were carefully recorded.
You may be surprised by what they found.
The results are shown in this simple chart:
It wasn’t only how they behaved that was remarkably different.
The healthy food group did “48% better in the games overall” – that’s a huge improvement in performance.
Now, of course, there are a lot of factors associated with the foods served at this party, but it’s an interesting experiment nonetheless.
And I’m sure you have noticed that you feel better after eating healthier food–so it only makes sense that your kids would as well.
And when you feel better, you act better.
Are We Setting Our Kids (and Ourselves) Up for Failure?
After watching the segments that you can see below, I couldn’t help think that many kids are inadvertently being set up for failure by their own parents. Moms and Dads certainly intend to do the best for their children, and part of this can mean feeding them “regular food” that won’t set their children apart from their friends.
But in doing so, our children are being sabotaged in ways that make it difficult for them to perform school tasks successfully.
They’re fed processed foods that can make them aggressive and difficult to control. Then, as if that weren’t bad enough, they’re penalized for their inability to learn and their out-of-control behavior.
We all know that a child who is constantly hitting other children, having tantrums, and running around wildly is a child who is continually reprimanded. We also all know a child who doesn’t follow teachers’ instructions, can’t remember what he or she was taught yesterday, or can’t concentrate long enough to finish a task receives poor grades and negative feedback.
No parent wants this for his or her child.
Tragically, in the worst cases, kids who are simply reacting to what they are being fed end up taking unnecessary prescription drugs or are sent to special schools.
Helping Kids Succeed with Good Nutrition
How do we feed children to prepare them to succeed in school and get along in society? Generally speaking, the more natural a food is, the less likely it is to cause a severe behavioral reaction. Keep in mind that there are plenty of individual differences in how children react to specific foods and additives.
One family might discover that avoiding a certain additive transforms their child into a little angel, while in another family cutting out wheat may do wonders.
That said, watch out in particular for the Three Substances I list below, which are often linked with behavioral problems.
Watch the following video to see what happened to these two groups of kids — and be thinking about how we might be setting our kids up for either failure or success, based on what we are feeding them.
The Experiment on Video
After the initial publication of this post, the videos of the experiment were removed from The Food Hospital’s website. Following is what is now available.
Watch as parents and a psychologist evaluate behavior during play and learning tasks.
The coordinators divided up the groups, what they ate, and how things started to play out.
Full Experiment
I can’t embed this video here but you can go to this link and watch it.
It’s split up into parts. The time stamps for the experiment are:
From 9:22 – 13:27 and
from 25:28 – 31:55.
Here’s a small part of the experiment as well.
**Note: The woman, when stating that they “don’t know” what made the difference, mentions “E numbers.” From Wikipedia, this is what she is referring to: “E numbers are codes for chemicals which can be used as food additives for use within the European Union and Switzerland (the “E” stands for “Europe”).They are commonly found on food labels throughout the European Union. Safety assessment and approval are the responsibility of the European Food Safety Authority”
Study Conclusion
Those who ran the study say that they don’t know what it is in the party food that affects the children. Is it the sugar? The artificial coloring? Maybe the lack of essential nutrients? It’s not clear.
I suspect it’s a combination, with individual children being more affected by different things.
What is clear is that children not only behave better but concentrate better, follow instructions better, and remember more when they eat healthier food.
Let’s not forget that concentration, following instructions, and memory are fundamental building blocks of the learning process and vital for success at school.

Have you noticed (or suspected) foods affect behavior in your house?
