Opening the door to our children’s potential

New research suggests iodine supplementation positively impacts kids’ intellect

In groundbreaking new research iodine supplementation to correct the mild deficiency found in some Australian children has led to significant improvements in cognitive brain function.

The first-of-its-kind study conducted at the University of Otago in New Zealand and published in the American Journal of Clinical Nutrition this month involving 184 school-aged children, assessed cognitive improvement with iodine supplements. The iodine tablets developed for the study were supplied by Blackmores.

What is iodine?

Iodine is a micronutrient required for healthy thyroid function, and is also important in pregnant women and school children for healthy brain development.

How does iodine deficiency affect children?

If a child does not have enough iodine, their learning and cognition can be affected. Pregnant or breastfeeding women need iodine to ensure the foetus or newborn is provided with enough thyroid hormone, which helps brain development.

Why might our diets be low in iodine?

In Australia and New Zealand, natural iodine levels are low in soils, and this affects the levels of iodine in foods such as vegetables, grains and livestock i.e. cattle and sheep.

Recent trends in lifestyle factors, for example using sea salt rather than iodised salt in cooking, have also decreased the amount of iodine in our diets.

We also used to get iodine from milk. Over the last 40 years dairy farmers used iodine based solutions to sterilise milk containers, but during the last five years they changed to chlorine-containing sterilisers.

How can I boost my iodine levels?

According to Pam Stone, Blackmores’ Director of Education, good sources of iodine-rich food include seafood, dairy products and iodised salt, but trying to obtain the recommended levels from food can be difficult. “Supplementation is a positive means of ensuring you are consuming adequate levels,” she said.

A landmark study showed that iodine supplementation of mildly deficient children improved cognition and suggests that inadequate iodine intakes could prevent children from attaining their full intellectual potential.

Did you know that to help address iodine deficiency in Australia, Food Standards Australia New Zealand (FSANZ) have announced that all bread products must now be made with iodised salt?

However, for pregnant women and young children to get the recommended daily dose they would need to eat approximately 5 times the average serve of bread per day*!
