PUFAs Improve Cognitive Function
A recent study has found that children’s working memory, cognitive function and possibly reading ability may benefit from the consumption of polyunsaturated fatty acids (PUFAs). The study noted that while scientific literature has indicated that premature infants and children with developmental disorders benefit from a high intake of PUFAs, it is now evident that normal school-aged children may also benefit from additional consumption of PUFAs.
The study examined the dietary intakes of various types of fats (saturated, mono-unsaturated and polyunsaturated fats and cholesterol) and assessed these for effects on cognitive and psychosocial functioning in 3666 six to 16 year olds. Interestingly it was the type of fat, not the total quantity that was important. It was found that each additional 10 g or 5% increase in energy intake from PUFAs was associated with better performance in a test assessing short-term memory (digit span test) whereas increasing cholesterol intake was associated with poor performance.
Comment:
This finding reinforces the need for dietary awareness, with avoidance of high cholesterol containing foods and dietary enrichment with PUFAs. Currently the industrialised Western diet is associated with a higher intake of cholesterol and lower intake of PUFAs. Children’s Omega-3 complex is a pleasant tasting, orange flavoured, liquid fish oil designed specifically to supplement the diets of developing and school-age children.
