Health benefits of Omega-3
Omeg-3 contains polyunsaturated fatty acids including EPA (Eicosapentaenoic Acid), DHA(Docosahexaenoic Acid) and DPA(Docosapentaenoic Acid). Extensive research suggests Omega-3 fatty acids are important to overall health, particularly for the function of the heart, brain and nervous system. EPA is well-known to help reduce blood clotting, lower blood pressure, improve blood fat levels, and prevent sudden heart attacks. DHA helps are building block for the brain, nervous system and retina, supporting the development of sensory, perceptual, cognitive and motor neural systems. DHA also helps support neurological functions in the elderly.
In addition, Omega-3 helps reduce risk of blood vessel re-blockage after heart bypass or angioplasty, artery hardening, weight loss, blood sugar levels and period and bone pain. It helps mood behavior, sleep, and may prevent certain types of cancer.
Why we should take Omega-3 dietary supplements?
Although Omega-3 is important in our health, it cannot be produced in our body. It must be derived from our diet. However, the modern diet in many societies contains far less Omega-3 than health authorities recommend. In North America, current intake of Omega-3 fatty acids is generally only about 15% of the target intake(900mg/day) officially recommended by the American Heart Association for those with coronary heart disease. In the case of healthy individuals, intake is only 20% of the 650mg/day advised by experts, while the average three-year-old child consumes only 19 mg Omega-3 per day(Less than 10% of RDA).
Many governmental authorities and health organizations have recommended frequent fish consumption or supplements with those fatty acids to achieve the recommended daily intake. The aim of recommending consumers to eat fish as a primary source of DHA/EPA is threatened by the fact that suitable fish are increasingly expensive and hard to find. The stocks of wild salmon, tuna and other species that are not contaminated with mercury or other pollutants are increasingly restricted. An alternative is to take dietary supplements rich in DHA/EPA.
