How does eating fish protect my heart from air pollution?

In this ever more polluted world, sometimes you just can't avoid a little bit of particulate matter in your lungs.

So go fish! Eating finny food not only reduces your risk for heart disease but also may protect your heart from air-pollution-induced arrhythmias.

Short-term exposure to small airborne particles spewed from cars, power plants and other industrial sources may cause an irregular heart rate -- serious stuff because it could open the door to heart arrhythmias and even heart attacks in people who are over 60 or have heart or lung diseases.

But fish could help thwart that unhealthy chain of events. A study found that the omega-3 fatty acids in fish oil may help alleviate those irregular beats. That's just what happened when people over 60 who were exposed to particulate matter took a daily fish oil supplement.
