Has taking fish oils caused a gout flare up?
Q) My father has just been diagnosed with gout after a very nasty attack last week where his left toe swelled up. He has just recently started taking omega-3 ﬁsh oils for general health beneﬁts but I see from your information booklet that ﬁsh oils are high in purines. Do the overall beneﬁts to his health outweigh the increased risk of further attacks of gout or should he stop taking the ﬁsh oils altogether? What would you advise?

A) I think you've misinterpreted the advice in the information booklet on gout – it's oily ﬁsh (sardines and mackerel) which are discouraged, not ﬁsh oils. Sardines and ﬁsh roe are high in protein and this is bad because an end product of protein metabolism is uric acid, the cause of gout. As cod liver oil is almost 100 percent fat it's unlikely to be a problem, providing you take it in moderation. Incidentally, probably the most common cause of a high blood uric acid in elderly people is the use of diuretic (water) tablets, but a moderate alcohol intake should also be considered a risk factor.
