Is your child eating enough oil?
The media has been focusing for quite some time on the benefits of fats and oils in our diets. It seems that finally the world is realizing that saturated fats are not the killers we once thought they were and we are becoming aware that not all oils available in supermarkets are as healthy as marketers would have us believe.
Standing out from this muddle of misinformation over the decades has been the fact that Omega-3 oil is a key nutrient for brain help.
None of us would disagree that learning takes place largely in the brain. It follows that if the brain is deprived of the nutrients that it needs to be healthy, it won’t be able to fulfil its learning function.
We can all be labelled as ‘fat heads’ because our brains are predominantly made of fat. Almost all of its structures and functions are crucially dependent on essential fatty acids. These cannot be made by our bodies but come directly from our food. Pause then, for a moment, and consider the impact of the last thirty years or so during which we were sternly told that fat was bad for us and we should consume low-fat or fat-free products. We now know without doubt that if a child’s brain is deficient in the important fatty acids (mainly Omega-3) it will still function but will process information far slower than otherwise. Imagine an outdated computer that works but processes slowly, compared to an up-to-date version, which processes at the blink of an eye
Researchers in the UK have found that a child’s blood levels of Omega-3 (specifically a component known as DHA) can significantly predict how well he or she is able to concentrate and learn. From sampling nearly 500 schoolchildren, they found that higher levels were associated with better reading and memory, as well as with fewer behaviour problems, as rated by parents and teachers
Many of the children identified as having below-average reading skills showed levels of Omega-3 that were way below the level considered optimal. Their parents also revealed that almost nine out of ten children in the sample ate fish less than twice a week, and nearly one in ten never ate fish at all. This is significant because fish is the only really practical source of Omega-3 in our diets. If a child is sensitive to fish, flaxseed (or flax oil), pumpkin seeds and walnuts provide the most commonly available alternatives.
In the light of this knowledge, it makes sense to encourage children to eat fish from an early age. We have good sources of cold water fatty fish (which are the best sources of Omega-3). Snoek, hake, trout, pilchards and herrings will all feed our hungry brains – but not battered and deep-fried – learn to grill, bake or lightly braai!
The question naturally arises about Omega-3 supplements – particularly in children who are picky eaters. I’ll be addressing this in next week’s post.
