I have to say, at this juncture, for all the good Ben Goldacre has done in highlighting the benefits of questioning how science is reported, he can be a little overselective in his supporting papers.

The scandi's have shown a link (using their supreme medical records) between high fish diet and reduced Alzheimer's onset.

ahem.
B.G. (pbuh) has issues with the "trial" of fish oils in boosting children's education. specifically the Durham trial.
His issue is with the lack of evidence, the changing of the trial etc.
it is not with fish oils per se.
