Something Fishy About Fish

There is no doubt about the immense value of protein and essential fats in fish, but fish is contaminated with non-biodegradable artificial toxins tend to accumulate in the food chain. A survey of salmon, published in 2004 in the journal Science, show that all the salmon have some kind of contamination with PCBs (polychlorinated biphenyls), dioxins (industrial pollutants that are not biodegradable), the dieldrins and toxaphene, which are pesticides. Fish caught in the Pacific have consistently lower levels than fish caught in the Atlantic. The survey also showed that farmed salmon consistently had higher levels than wild salmon.
While nutritionists often recommend eating more fish, it is easy to get confused with the recommendations to prevent pollution of fish mentioned above. In the case of dioxins and PCBs, they are in the food chain and other residues of pesticides are likely to accumulate more of the feed fed to farmed fish. Organic fish which are fed less contaminated food, have a diet consisting of at least half of aquatic origin, ie, other fish. Because of the toxins that are not biodegradable transmission in the food chain, organic fish are not exempt. It depends on the sea in swimming that determines the level of toxins.Read More
