One does wonder how the omega thing has gone so viral; the only randomised controlled trial carried out in this country found that
Despite the wide range of cognitive and behavioural outcome measures employed, only three significant differences between groups were found after 16 weeks, one of which was in favour of the placebo condition.(Kirby et al, 2010)
Still, guess they are harmless, even if they give you fishy burps. The rest of that stuff is just plain weird, TP.
Hope you're enjoying the book- it was I who suggested it and I think it's due for a relaunch. John O' Farrell deserves to make as much money from it as the snake oil companies do from their potions!
Amber, you got there before me! A few years ago I fell for the Horizon (was it Horizon?) program about a particluar brand of fish oils. Then I read Ben Goldacre's Bad Science (a must for everyone) and stopped wasting my money. 2/3 of my DCs don't like fish very much, and I don't imagine it did them any harm, but I don't think imagine it helped them at school either
Eta: I did give DS2 a banana on the way to school when he was doing his 11plus, but mainly as an excuse to get some extra food into him as he wasn't that keen on breakfast.
