Eating fish twice a week can reduce the risk of heart disease.

The American Heart Association (AHA) recommends eating fish once or twice a week, preferably fatty fish. Additional evidence suggests that fish can help prevent heart disease.
the American Heart Association (AHA) has published specific recommendations that adults should strive to eat 3.5 ounces of fish twice a week. The best choice is oily fish with large amounts of omega-3 fatty acids. Options include salmon, longfin tuna, mackerel, lake trout, mackerel and sardines. The AHA also cautions people not to eat fried fish no matter how you eat it. Because studies have found that people who like fried fish are at higher risk of heart failure.The main omega-3 fatty acids in fish are EPA and DHA, said Sonia Angelo, a registered dietitian at the
and a spokeswoman for the Society for Nutrition and Nutrition. The EPA has an anti-inflammatory effect that may help fight atherosclerosis and stenosis, which may prevent heart attacks, Angelon said. In addition, omega-3 fats make blood less likely to clot, and high doses can help reduce triglycerides.Eric Rim, a professor at the Harvard School of Public Health at the
, and lead author of the May 17 report from the American Heart Association, said: "Scientific studies have further confirmed the beneficial effects of eating seafood rich in omega-3 fatty acids, especially when it replaces less healthy foods. According to new reports, many large studies have found that people who eat fish at least once a week have a slightly lower risk of heart disease, stroke, heart failure and sudden cardiac death. "In two large U.S. studies, replacing 3 percent of the protein calories in processed meats with protein in seafood reduced the risk of dying from heart complications or stroke by 31 percent. Therefore, the Heart Association recommends that fish instead of red or processed meat or other unhealthy foods seems to be key.the
Heart Association says fish may even benefit people who already have heart disease. A study of heart disease patients found that those who ate fish twice a week were 27 percent less likely to die in the next two years than those who received only standard treatment.
but aha notes that seafood does contain mercury. Pregnant women and young children should avoid certain large mercury-rich fish, such as sharks, swordfish and mackerel. But for most adults, the benefits of eating fish outweigh the potential harms of mercury.
