At A GlanceA new CDC report suggests that most Americans have lower-than-optimal levels of two important omega-3s, EPA and DHA. You can boost your omega-3 intake by eating foods like fatty fish, chia seeds, and flaxseeds. But one finding stands out: Most Americans may not be getting enough of two important omega-3 fatty acids, EPA and DHA, which are found in foods such as fatty fish. Omega-3 fatty acids are a type of polyunsaturated fat that play important roles in the body. For long-chain omega-3s, the American Heart Association recommends that people without coronary heart disease eat at least two servings of fish per week, especially fatty fish.
