All fats are not created equal: Some are good (unsaturated), some are bad (saturated), and some are really terrible (trans fats). Among the good fats are omega-3 fatty acids, which offer a number of health benefits, including helping to lower your risk of heart disease and stroke.
Omega-3s are called essential fatty acids because they are required by the body and must be obtained through food and supplements (the body can?t make them on its own). There are three types of omega-3s, each essential for optimal health. Two of them, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found mainly in cold-water fish, such as herring, sardines 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 attack. The third kind, alpha-linolenic acid (ALA), is found in plant sources such as flaxseed, walnuts (polyunsaturated fats) and dark leafy greens. Once these food sources have been consumed it will be converted into EPA and DHA which is the types of EFA?s most readily used by the body.
????????? The best and most natural way to increase your intake of omega-3s is to eat more oily fish (at least 2-3 servings per week) and dark leafy greens, and to add ground flaxseed and walnuts to your diet in moderation. The American Heart Association recommends getting 1 gram daily of EPA and DHA, preferably from oily fish, although it says that an omega-3 fatty acid supplement could be considered in consultation with your physician.. For people who have high LDL elevated triglycerides (bad blood fats), which can put you at risk of developing heart disease fish oil can be quite effective when used under a doctor?s watch.
A Word of Caution
????????? Be advised that people with certain medical conditions, such as those taking anticoagulants, those with bleeding disorders, or those with uncontrolled hypertension, should always 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.
