From the cite by lazybratsche:
"*A key difference in the typical Nunavik Inuit’s diet is that more than 50 percent of the calories in Inuit native foods come from fats. Much more important, the fats come from wild animals…
Wild-animal fats are different from both farm-animal fats and processed fats, says Dewailly. Farm animals, cooped up and stuffed with agricultural grains (carbohydrates) typically have lots of solid, highly saturated fat.
Wild animals that range freely and eat what nature intended, says Dewailly, have fat that is far more healthful. Less of their fat is saturated, and more of it is in the monounsaturated form (like olive oil). What’s more, cold-water fishes and sea mammals are particularly rich in polyunsaturated fats called n-3 fatty acids or omega-3 fatty acids. These fats appear to benefit the heart and vascular system. But the polyunsaturated fats in most Americans’ diets are the omega-6 fatty acids supplied by vegetable oils. By contrast, whale blubber consists of 70 percent monounsaturated fat and close to 30 percent omega-3s, says Dewailly"
