Nope, it's not a fish story. Evidence has confirmed that fish oil helps fight heart disease. But does that mean you should order the catch of the day - every day?

Fatty fish like mackerel, sardines, albacore tuna and salmon have been shown to benefit the heart of healthy people, and people at high risk of, or who already have cardiovascular disease. Dr. Steven Longobardi says that "for people that have history of heart attack, large studies have shown that it reduces the incidents of future heart attacks by up to 20%."

The American Heart Association recommends eating fish at least two times a week. But, like Brandon Delt, not everyone's a fish-lover, so fish oil supplements are another option for getting the recommened omega three's. "I hate fish, so I learned to take 1000 milligrams of omega 3 fatty acid or supplements."

Dr. Longobardi also says that to get the equivalent of the 1,000 milligrams of fatty fish oil, you'd have to eat at least 4 ounces of a fatty fish - every day. "The only problem with that is that people tend not to eat that much fish every day and eating that much fish can increase the risk of mercury poisoning and other contaminations."

Dr. Longobardi explains that research also suggests that fish oil can help lower high blood pressure and may reduce the risk of coronary artery re-blockage after angioplasty. "People who have a known history of heart disease or people who have high triglyceride levels would be an excellent candidate for fish oil supplement, that's a prescription."

Ask your doctor the best way for you to reap the most benefits from fish oil.

Consider fish oil supplements for heart-related conditions only if you eat fish less than twice a week and you've discussed it with your doctor.
