The second point is the decisive reason why salmon can be eaten raw! ! Among all fish, salmon contains the most omega-3 unsaturated fatty acids (about 27g per100g salmon).
As we all know, meat food can be divided into fatty acids and unsaturated fatty acids.
However, only unsaturated fatty acid is a kind of fatty acid that constitutes body fat, and it can be directly absorbed by human body without reprocessing body fluids.
Furthermore, the unsaturated fatty acids contained in salmon can be divided into monounsaturated fatty acids and polyunsaturated fatty acids according to the number of double bonds. Among food fats, monounsaturated fatty acid is oleic acid, and polyunsaturated fatty acid is linoleic acid, linolenic acid and arachidonic acid. The human body cannot directly absorb unsaturated fatty acids, which is the fundamental reason why most fish can't be eaten raw! !
