In seeking to explain why the incidence of cardiovascular disease was so low among the Eskimos of Greenland, the researchers discovered the powers of omega-3. They found that Eskimo food consisted mainly of
Pisces, meat of seal and whale, very rich foods in polyunsaturated fatty acids of omega-3 long chain.
Omega-3 are part of the family
fats, lipids. They belong to the essential fatty acids. They are called "essential" because our body can not manufacture them. We must therefore bring them through our diet.
There are three main families of nutrients: proteins, carbohydrates and lipids. These are essential to a balanced diet, because they participate in the f
ormation cells and promote the smooth
functioning of the nervous system.
Lipids are composed of a base member: the fatty acid. Several fatty acids combine to form a lipid. Depending on how they bind to each other, we talk of saturated or unsaturated fatty acids.
If there is no double bond is a saturated fatty acid. If there is only one, it is a monounsaturated fatty acid. And when there are multiple double bonds, are polyunsaturated fatty acids. Omega 3 are
Polyunsaturated fatty acids.
