The capsules given to children in the trial contained oils high in Omega 3 fats, which are found naturally in oily fish such as mackerel, salmon and sardines and in some plant crops such as rape seed.
The results have not yet been published, but they are expected to show a statistically significant improvement in school performance in the group of children given Omega 3 supplements. This does not mean that every child benefitted from the treatment - many did not. But according to Portwood, about 40% of children showed some clear improvement.
The above excerpt from the same article kind of pisses me off. I understand the Doc’s reservations, however, nobody is going to go broke giving their kid fish oil. Nobody. It’s essentially a win-win proposition because of the myriad other health benefits.
