Some fish — such as salmon, tuna, sardines, mackerel and herring — contain a type of fish oil called omega-3. Studies have found that omega-3 not only helps lower cholesterol, but also helps to reduce the chance of blood clot formation and protects against irregular heartbeats, which can cause heart attack and sudden cardiac death. The American Heart Association recommends about 3 ounces of fish at least two times a week or more. Fish oil supplements are also an option.
