If you're worried about heart disease, eating one to two servings of fish a week could reduce your risk of dying of a heart attack. Fish contain unsaturated fatty acids, which, when substituted for saturated fatty acids such as those in meat, may lower your cholesterol. But the main beneficial nutrient appears to be omega-3 fatty acids in fatty fish. Omega-3 fatty acids are a type of unsaturated fatty acid that may reduce inflammation throughout the body.
