Omega 3 Refresher

As you may already know if you're following the South Beach Diet, Dr. Agatston frequently stresses the importance of getting enough omega-3 fatty acids in your diet. That's because omega-3s offer important health benefits.
Omega-3s are essential fatty acids that must be obtained through diet or supplements. The human body does not possess the ability to make them. There are three types of omega-3s, each essential for optimal health. Two kinds, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found mainly in cold-water fish such as tuna and salmon. EPA and DHA are extremely effective at reducing inflammation and preventing the formation of blood clots, thus reducing the risk of stroke and heart disease. The third kind, alpha-linolenic acid (ALA), is found in plant sources such as flaxseed, canola oil, and dark, leafy greens. ALA has been shown to lower the "bad" LDL cholesterol, and an ALA-rich diet may lower the risk of a heart attack.
The best and most natural way to increase your intake of omega-3s is to eat more fish (at least two servings per week) and leafy greens, and to add ground flaxseed and canola oil to your diet. Dr. Agatston also believes that, in addition to the above, all adults should take a fish-oil supplement daily. He recommends one to two grams of EPA plus DHA per day. People with high triglycerides may need more — at least four grams daily.
Be advised that people with certain medical conditions, such as those taking anticoagulants, those with bleeding disorders, or those with uncontrolled hypertension, should consult with their physician before taking fish-oil supplements. Also note that certain fish, including swordfish, king mackerel, and tilefish, contain high levels of mercury. Women who are pregnant or may become pregnant, nursing mothers, and children should avoid fish high in mercury.
