Fish Oil Delivers Few Heart Benefits, Study Finds

A bad day for woo-woo.

Millions of Americans take fish oil supplements, hoping to keep their hearts at their healthiest. But a new study has raised questions about these popular dietary supplements, especially whether they can replace a healthy, balanced diet.

Fish oil, a combination of omega-3 fatty acids, is a centuries-old staple of pharmacy shelves, and scientists have devoted much research to investigating its effects on heart health. So far, the evidence has been inconclusive -- some studies have found fish oil has been major in preventing heart attacks, strokes and sudden cardiac death, while others have found fish oil has no benefits at all.

Oops.
