We parents generate numerous hypothesises to explain our children’s behaviour—boredom, too much screen time, or lack of sleep. But sometimes lack of nutrition or chemicals may be the root cause. Much research has been done to link junk food and diets laden with artificial colours and preservatives to hyperactivity and the results have been inconclusive, but studies indicate the prevalence of Attention Deficit Hyperactive Disorder (ADHD) is as high as five to 10 percent in Australia. Boys are nine times more likely to be diagnosed with ADHD than girls. Affected children show signs like the inability to concentrate, the tendency to be easily distracted, a decrease in attention and an increase in impulsive behaviour. These symptoms may also present in children sensitive to certain foods so it is worth looking at the food thought to cause behavioural problems, but a clear diagnosis can only be made by a health professional.Processed “junk” food, that includes artificial flavours, colours and preservatives, is the main culprit, but some naturally occurring additives are also under scrutiny. Such additives include glutamates (a flavour enhancer found in soy sauce and mushrooms, for example), salicylates (preservatives and essential micronutrients found in acidic fruit and many other foods) and amines (flavour enhancer found in things like chocolate and aged cheese). Food containing wheat can also be a trigger.A diet high in protein and low in refined carbohydrates, low in sugar and packed with fresh fruit and vegetables will provide good nutrition. Fish should also be included because Omega-3 fatty acids have been shown to improve behaviour and attention in children. Other essential nutrients include magnesium, calcium, zinc, iron, probiotics and B-vitamins.Essentially, choosing to focus on nutrition rather than resort to medications like Ritalin may alleviate some of the behaviour problems commonly seen in children.Image: ShutterstockResources: Food – The Cause of Bad Behaviour – Amy Pongrass - TheFoodCoachAustralian Guidelines on Attention Deficit Hyperactive Disorder – 2009
