Can fish oils benefit our health?

Fish oil supplements are popular because they are believed to have health benefits. The American Heart Association (AHA) recommend eating oily fish to promote heart health. However, studies have produced mixed results.
In 2012, a National Health Survey found that around 7.8% of adults in the United States (U.S.), or 18.8 million people, and 1.1% of children aged 4 to 17 years, had taken a fish oil supplement in the previous 30 days.
