Concern over supplements is not cod

SALES of fish-oil supplements have soared boosted by claims that they can increase longevity, help curb disease and even improve children’s behaviour.

But, there’s a dilemma for fish consumers — should they put their health, which they believe to be aided by oily fish rich in omega 3 nutrients, before the wellbeing of diminishing fish stocks, globally?

In Ireland, fishermen are being encouraged to broaden whitefish activities to ease the pressure on over- fished species, such as cod and monkfish. Yet, there must not be a house in the country without cod liver oil in some form. The purveyors tell us it helps maintain health, including mobile and supple joints, as well as enhancing the heart and circulation.
