Fish has been known as brain food for decades, if not longer. Now we have the science to prove it. The WHO and FAO jointly recommend that pregnant and nursing mothers eat seafood twice a week to optimise brain and nerve development in the growing fetus and infant.

For toddlers and older kids it’s all about creating healthy habits. Whatever food kids learn to enjoy will be the food they most likely choose once they leave home. Teach your kids to love seafood. Don’t give up at the first screwed up nose. Set an example. Make it a habit. How about making Friday ‘Fish Day’?

Toddlers who eat fruit as a snack rather than with meals are three times more likely to have iron deficiency. “But I thought it was healthy to give my child fruit as a snack,” commented the health professional sitting near me. “It is,” replied Dr Clare Wall, one of three child nutrition experts speaking at a seminar I attended this week. “But it’s also important for toddlers to eat fruit with a meal because it increases iron absorption from that meal.”

One in six Kiwi toddlers are iron deficient and around two-thirds don’t eat enough iron to meet the recommended daily intake. For most, it’s not bad enough to cause anaemia but it is bad enough to affect their behaviour and brain

Eighty percent of our adult brain is formed by the age of three. So just at the time when our toddlers have learnt that saying “NO” causes the big people around them to act in all sorts of funny ways, we need to make sure they somehow get enough brain nutrients into them, particularly iron, zinc and omega-3 fats.

Iron carries oxygen around the body. If a muscle is deprived of oxygen, it dies. If a toddler doesn’t get enough iron the brain doesn’t get enough oxygen. It can’t develop so well – and the damage is irreversible.
