The health benefits of salmon are unquestioned . On the one hand, it is abundant in Omega-3 fatty acids, which are essential for heart health, then easily digested proteins or amino acids, along with vitamin D, vitamin A and some B vitamins addition, salmon it is a rich source of minerals such as selenium, zinc, phosphorus, calcium and iron.
However, most of the salmon sold in fish markets comes from farms and not from nature. Virtually all salmon sold in North America labeled “Atlantic” comes from farms. If taken into consideration that most of the natural habitat of the fish on the eastern side of the US has been destroyed, this will not be as surprising as it seems.
Unfortunately, farm-raised salmon does not have the same nutritional value of wild salmon. Farmed salmon is much higher in fat – which contains three times more saturated fat than wild salmon. It also has 46% more calories that come mostly from fat.
On the other hand, wild salmon is a rich source of minerals such as potassium, zinc and iron.

- artificial colors
first, farm-raised salmon gets its color from food additives compared to wild salmon, which feeds primarily on krill, making her pink skin due to red algae eat krill. Farm salmon breed does not feed on krill, and its pink color is anything but natural. In fact, it is one of the most common colors for use in fish feed – canthaxanthin, which can lead to eye defects and damage to the retina. The use of this compound by fish farmers in Europe has been restricted by the European Commission, whereas in the US, which has to be labeled in order to identify farmed salmon and dyeing.
According to the results of a recent study, the levels of pesticides, dioxins, PCBs and other contaminants were almost 10 times higher in farmed salmon than in wild Pacific salmon. The study also found that three other toxaphene potentially carcinogenic substances-dioxins, dieldrin and constantly found in farmed salmon. The study authors reported that a portion of farmed salmon a month is a maximum that most people should eat.
Another issue that has often been discussed is the use of antibiotics on farms of industrial salmon order to avoid that fish is easily infected with various diseases. With the consumption of such salmon, also ingest some of the antibiotics and other substances.
the difference between wild and farm-salmon farming
There are several factors to consider when buying salmon. If you want to know the difference between the two, look at the fish closely. farm-raised salmon has stripes visible fat and flesh is orange. Wild salmon, by contrast, has deep red stripes and no visible fat color. Last but not least, look at the price.
