Better Nutrition for Better Behavior

By: Amy Butler

The most important meal of the day

That’s right, breakfast! If you’ve ever run out of the door without breakfast on a workday, you’re probably familiar with the distraction that hunger can cause. This is no different in children – attention and memory are improved in children that have breakfast compared to those who don’t, and some types of breakfast seem to improve attention more than others. For example, children who ate low GI (or glycemic index – a measure of how quickly your blood sugar rises after a meal) breakfasts saw greater improvement in attention than those who had high GI breakfasts.¹ Common high GI breakfast foods are white bread, high-sugar cereal, and baked goods like muffins and pastries, whereas low GI options include oatmeal, eggs, and wholemeal toast.

Examples of how to turn a high GI breakfast into a low GI one below:

Of course, it’s a little reductive to say that it’s only breakfast that is important when thinking about attention and behavior in children. Making sure children eat regularly through the day and focusing on low GI foods ensures they have sustainable energy to focus and helps to reduce the poor behavior that often arises from hunger.

Specific nutrients for children

As well as ensuring that children eat regularly, it can be helpful to ensure adequate intake of a few key nutrients.

• Magnesium, in concert with Calcium, helps calm the nervous system by regulating nerve firing and reducing over-excitation of the nervous system. For diets low in magnesium, supplementation might help to reduce anxiety.²
• B Vitamins support all areas of health and mood; in particular B6 supplementation (with magnesium) has demonstrated improvements in symptoms of hyperactivity and aggressiveness in children.³
• Iron deficiency in children has several symptoms, one of which is poor behavior, and treatment with supplemental iron can reverse the behavioral symptoms.⁴ There’s no harm in increasing iron-rich foods in the diet (for example spinach, beans, lentils, tofu, and red meat) as our bodies are very good at regulating iron from food sources; however you should only ever give children iron supplements if your doctor has identified an iron deficiency.
• Zinc insufficiency is associated with a number of behavior problems including anxiety/depression, withdrawal, emotional reactivity, attention problems and aggressive behavior.⁵ Including more beans and lentils, seeds like hemp or pumpkin, nuts like cashews or almonds and dark chocolate can give your kids a boost of zinc in their diets.
• Omega-3s have been found to improve problems like inattention, hyperactivity and oppositional behavior in children, both with and without a diagnosis of ADHD (attention-deficit hyperactivity disorder).⁶ As well as oily fish, omega-3s can be found in seaweed, chia seeds, hemp seeds, flax, walnuts and beans.
• Protein keeps them fuller for longer, helping to avoid afternoon ‘hanger’ tantrums!

To help achieve the levels of nutrients kids needs to thrive, try adding a Kids Good Stuff multivitamin smoothie to their daily routine. It contains more than 50 ingredients including magnesium, calcium, B vitamins, naturally occurring iron, zinc and protein.

Things to avoid

Experiment with removing artificial flavor enhancers and preservatives to see if this makes a difference in your child’s behavior (some children are more sensitive than others); these include:

Allergies and intolerances

Allergies and intolerances don’t always show up as the classic symptoms of rash, itchy throat, bloating, or diarrhea. Behavioral problems can also be a sign of an undiagnosed allergy or intolerance. Speak to your doctor if you suspect this and they can arrange an allergy test for you.
