Omega-3 Fatty Acids
Omega-3 fatty acids are a group of polyunsaturated fatty acids that are important for a number of functions in the body. Some kinds of omega-3s, including EPA and DHA, are found in fatty fish—such as salmon, tuna, and trout—and shellfish—such as crab, mussels, and oysters. A different type of omega-3, called ALA, is found in some vegetable oils—such as canola and soy oils. Omega-3s are also available as dietary supplements. Moderate evidence has emerged about the health benefits of eating seafood (fish and shellfish). The health benefits of omega-3 dietary supplements are unclear.
