为什么吃鱼有利于心脏健康

I've heard that eating fish is good for my heart. Why is that?Fish and shellfish contain a type of fat called omega-3 (oh-MAY-guh) fatty acids. Research suggests that eating omega-3 fatty acids lowers your chances of dying from heart disease. Fish that naturally contain more oil (such as salmon, trout, herring, mackerel, anchovies, and sardines) have more omega-3 fatty acids than lean fish (such as cod, haddock, and catfish). Be careful, though, about eating too much shellfish. Shrimp is a type of shellfish that has a lot of cholesterol.
You can also get omega-3 fatty acids from plant sources, such as:

• Canola oil
• Soybean oil
• Walnuts
• Ground flaxseed (linseed) and flaxseed oil
