Omega-3 fatty acids are a family of polyunsaturated fats found in foods such as fatty fish, walnuts, and certain oils. EPA and DHA, two well-known members of this family, are common ingredients in fish-oil supplements. Dietary patterns, cultural cuisines, and availability influence how people obtain these fats.
When exploring omega-3 intake, people consider taste, sustainability, cost, and whether to use food sources, supplements, or both. Routine consumption rather than single large doses is a typical approach for dietary fats in general.
