The Effects of Omega-3 Fatty Acids on Heart Diseases

Abstract

Omega-3 (ω-3) is a group of multiple unsaturated fatty acids, commonly found in deep-sea fish, seal oil. In recent years, ω-3 has become a hot topic in the treatment and prevention of cardiac diseases, however, a systematic explanation of the related regulatory mechanisms is lacking. The theme of this paper is the effects of ω-3 on heart diseases, after collected the data from last five years, then made a system analysis. Finally it concluded that ω-3 can raise benign cholesterol in high-density lipoprotein (HDL) and reduce body’s oxidized bad cholesterol in low-density lipoprotein (LDL).it also can participate in arachidonic acid metabolism to produce Prostaglandin-I-3 (PGI 3) to regulate vascular elasticity, platelets and thrombus quantity.in addition, it also has an important role in regulating human blood pressure, AS risk and heart rate. All of these indicators are linked to an increased chance of heart diseases, so the conclusion is that ω-3 mainly plays a role in relieving vascular obstruction and heart function.
