Abstract:
Flaxseed oil is a kind of natural health-promoting plant functional oil, containing large amounts of unsaturated fatty acids, with α-linolenic acid and linoleic acid having the highest contents. These two kinds of polyunsaturated fatty acids played an indispensable role in the metabolism, growth and development of the body. In addition, flaxseed oil also contained a variety of bioactive substances, for example, other unsaturated fatty acids (docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and prostaglandin (PG)), flaxseed cyclolinopeptides, vitamin E, secoisolariciresinol diglucoside, oleic acid and flavonoids also play active roles in the body. This article mainly discusses the various functions of linseed oil for the human body, such as the antioxidant effect of α-linolenic acid and vitamin E on the body, the hypolipidemic effect of α-linolenic acid on the body fluid and at the gene level, and hypoglycemic effect of α-linolenic acid through coordinating insulin. In addition, secoisolariciresinol diglucoside and cyclolinopeptide of flaxseed exhibited anti-inflammatory and anti-cancer effects. Polyunsaturated fatty acids play a role in preventing and treating cardiovascular diseases, anti-aging and anti-oxidation, regulating intestinal flora, enhancing eyesight and antibacterial actions.
