I Was Always Somewhat Worried About This...

Not all fish are created equal.

Before rushing to make salmon a staple of a heart-healthy diet, consumers should check the origin of their fish supply, a new study recommends.

It turns out where the salmon comes from — and what they are fed — determine whether the health risks will outweigh the benefits, according to the study recently published in the Journal of Nutrition.

Researchers found that the contaminant levels in farmed salmon from certain regions of the world increased the risk of cancer enough to outweigh the heart health benefits of salmon.

The toxin levels were so high in some farmed salmon from Europe that people should only eat a single serving once every five months, the study found.

I wonder how this compares to the toxins we consume in fish in Hong Kong?
