Mercury poisoning fish advice--USA research.
NEW US research has found government advisories on fish consumption
and mercury poisoning do more harm than good; rather than deterring
women from eating fish, they should ensure low-mercury fish is
available. The study, appearing in the American Journal of Preventive
Medicine, has warned such advice, particularly that aimed at women of
childbearing years, causes a drop in fish consumption, damaging
nutrition. Joshua Cohen, author from the Harvard Center for Risk
Analysis said: "Fish are an excellent source of omega-3 fatty
acids, which may protect against coronary heart disease and stroke, and
aid in the neurological development of unborn babies." Its report
says if pregnant women eat the same amount of fish but replaced mercury
high-fish with fish low in mercury, cognitive development benefits of
about 0.1 IQ points per newborn baby could follow. However, if pregnant
women decrease fish consumption by one-sixth, the loss of omega-3 fatty
would cut nutritional benefits by 80%.
