Recent studies suggest limiting the intake of some fish because of contaminants. But fish are a rich source of omega 3 fatty acids and many more studies suggest we are simply not getting enough.
Health groups have urged consumers to limit their intake of farmed salmon which can have high levels of PCBs, and limiting tuna and other fish because of mercury.
With the studies raising concerns about the man-made pollutants in our seas, some fish shop owners have watched sales slide by as much as 50 per cent.
And that worries some doctors who say their patients are not getting enough omega 3s -- essential fatty acids that some plants provide in small amounts, but are in rich supplies in fish.
Studies suggest those who don't get enough omega 3 fatty acids appear prone to a number of diseases.
"That includes certain forms of cancer, diabetes, arthritis, and other autoimmune disorders like lupus," says Dr. Peter Jones of McGill University.
