Omega-3 fatty acids are one of two groups of fatty acids—the omega-3s and the omega-6s—that are vital to human life. They are called essential fatty acids (EFAs), which the body cannot make but absolutely needs for normal growth and development. These fats must be supplied by diet.
There is strong evidence that omega-3 fatty acids protect a person against atherosclerosis andtherefore against heart disease and stroke, as well as abnormal heart rhythms that cause sudden cardiac death, and possibly autoimmune disorders, such as lupus and rheumatoid arthritis.
Numerous studies show that a diet rich in omega-3 fatty acids not only reduce joint inflammation but lowers bad cholesterol and triglycerides, the fatty material that circulates in the blood.
