Controlling your cholesterol can be tough at first when choosing the right foods to eat. Start by eating fatty fish and omega-3 fatty acids to control your cholesterol. If you are at risk for developing blood clots eating foods that are rich in omega-3 fatty acids will reduce your chances of serious health complications in the future. In people who have already had heart attacks, the fish oil, or omega-3 fatty acids, reduces the risk of sudden death. It is recommended that you include at least two servings of fish a week in your diet. Fish that are rich in omega-3 fatty acids mackerel, lake trout, herring, sardines, albacore tuna, salmon and halibut. You should bake or grill your fish to avoid having extra calories in your meal. You can also get small amounts of omega-3 fatty acids from foods like ground flaxseed or canola oil if you do not prefer fish.
