Describe the role of fish and fish oil supplements in preventing coronary heart disease
The omega-3 fatty acids in fatty fish, known as EPA and DHA, may benefit people at risk of CHD by suppressing inflammation, lowering blood triglyceride levels, reducing blood clotting, and stabilizing heart rhythm. In addition, including fish in the diet can reduce CHD risk because fish is low in saturated fat and often replaces meat dishes that contain saturated fat. The American Heart Association recommends consuming two or more servings of fish per week, with an emphasis on fatty fish. Of note, the use of fish oil supplements has not been shown to reduce heart attacks or heart disease-related deaths in most clinical trials.
