An disturbing report today suggests that taking omega-3 oils - ie fish oil - is no good for treating allergy.Actually it does not say treating, it says preventing.
That's a big difference. And I even tracked down the original article to try to make sense of it. Because my experience is that getting fish and other high omega-3 oils, eg rapeseed (or canola to Americans), into the diet makes all the difference.
It turns out the researchers looked almost entirely at studies involving pregnant women, breast-feeding mothers and new-born babies. So it was very much about prevention. I'd still like to know whether these studies are looking for diagnosed allergies or only for symptoms such as eczema and asthma. It's a big difference because salicylate hypersensitivity is not a "proper" allergy and can't be diagnosed by a simple test (apart from the Imperial Leather test - not recommended for babies).
So that's all right.
