Omega-3 fatty acids are essential fats in human nutrition and cannot be manufactured by the body, and must be consumed in the diet. The two main biologically active omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found in fish oil. There is also alpha-linolenic acid (ALA) which is found in vegetable oils.

Omega-3 fatty acids reduce mortality

Swiss researchers published results of clinical trials in the April 2005 issue of the Archives of Internal Medicine showing decreased risk of mortality using omega-3 fish oil. The trials also included statin drugs. The results combine 10,000 clinical trials from 1965 to 2003 which included 275,000 subjects.

In the trials statin drugs reduced overall mortality by 13 percent. Statin drugs advocated by conventional medicine to reduce cholesterol have side effects such as muscle pain, muscle loss, memory loss, liver failure, and fatigue. Omega-3 fatty acids reduced overall mortality by 23 percent.

Cholesterol

There are two types of cholesterol. LDL cholesterol is bad cholesterol that can lead to heart disease. HDL cholesterol is the good cholesterol. Low HDL cholesterol increases the risk of heart disease.

Not only do omega-3 fatty acids reduce the bad LDL cholesterol, they also increase the good HDL cholesterol.

Sources of omega-3 fatty acids

Good sources of omega-3 fatty acids include flaxseed, walnuts, and soybean oil. Cold-water fish such as salmon, mackerel, herring, and sardines have high concentrations of omega-3 fatty acids. To maintain the heart-healthy benefits of fish, bake or grill it. If dietary intake is insufficient, take fish oil capsules.

Other factors

Many other contribute to cholesterol levels and overall health. Maintain a normal body weight, avoid smoking and eat healthy food.
