An animal study conducted by Saudi researchers analyzed the risk of cardiac disease in rats supplemented with omega-3 fatty acid in the form of fish oil. It concluded that omega-3 supplements could reduce the amounts of total cholesterol and proteins in the blood of the animals, thereby improving their cardiac health.
Omega-3 fatty acids (also known as n-3 fatty acids) are polyunsaturated fatty acids that are essential nutrients for health. We need omega-3 fatty acids for numerous normal body functions, such as controlling blood clotting and building cell membranes in the brain, and since our bodies cannot make omega-3 fats, we must get them through food. Omega-3 fatty acids are also associated with many health benefits, including protection against heart disease and possibly stroke. New studies are identifying potential benefits for a wide range of conditions including cancer, inflammatory bowel disease, and other autoimmune diseases such as lupus and rheumatoid arthritis.
