There's no doubt salmon is an incredibly healthy source of fat and protein, as well as many other vitamins and minerals. Where the salmon is sourced, however, will make a significant difference regarding its health benefits and in this case, health risks. Not only do farm-raised salmon contain fifty percent less omega-3 fatty acids, they are also potentially exposed to a wide range of toxic chemicals.
Evidence indicates farm-raised salmon contain higher levels of mercury, PCBs, and dioxins than wild-caught salmon. To make them appear pinker, they're fed petrochemicals, not to mention the chemicals found within their daily diet. The real worry is up to ninety percent of these toxins bioaccumulate in the human body and can be passed onto an unborn child.
