20 Foods That Clean Arteries and Prevent Heart Attacks

16. Fatty fish

Fatty fish include many kinds, like sardines, salmon, or mackerel. They are all heart-healthy superstars because they contain high amounts of omega-3 fatty acids, which help reduce the risk of arrhythmias (irregular heartbeats) and atherosclerosis (the buildup of plaque in the arteries). It is recommended by the American Heart Association to eat fatty fish at least twice a week.
