Omega-3s are especially important for young children, and nursing
and pregnant women. But unfortunately, there are some fish, which carry toxins
that can become harmful when consumes frequently.
Contaminants in Seafood
Seafood contaminants includes heavy metals (i.e. Mercury –
affects brain function and development), Industrial chemicals (Dioxins and
PCBs) and pesticides (DDT). These toxins usually originates on land and make
their way in to the smallest animals and plants at the base of the ocean food
chain. As smaller species are eaten by lager ones, contaminants are accumulated
and concentrated. Finally lager predators (i.e. Shark, Sward fish) are ended up
with most toxins.
By choosing seafood carefully, consumer can minimize the
risk.
