NeoLife Salmon Oil Plus is tested for over 200 common pollutants with a standard of ZERO. This testing is important in light of many recent studies which show that fat loving toxins found in salmon and other fish can contribute to insulin resistance and diabetes.
In a recent study rats were fed crude salmon oil from farmed Atlantic salmon or purified oil. The animals consuming the crude salmon oil developed insulin resistance, abdominal obesity, and fatty liver disease. Researchers confirmed that the insulin resistance was triggered by persistent organic pollutants, in this case organochlorine pesticides. The researchers concluded, "Our findings provide evidence that exposure to POPs (persistent organic pollutants) commonly present in food chains leads to insulin resistance and associated metabolic disorders.
In many respects it is safer to rely upon NeoLife's Salmon Oil Plus than to eat salmon since so much of it is now farmed and who knows what pollutants are there?
