Definition: Omega 3 fatty acids are a group of unsaturated fats that are nutritionally important in a number of ways. The human body cannot produce them on its own, and therefore must obtain them from various foods, especially oily fish. The omega 3 fatty acids, including α-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, are thought to have anti-inflammatory effects on the body. Eicosapentaenoic acid is thought to have anti-asthma effects.
