Omega-3 fatty acids are a type of polyunsaturated fatty acid that is essential for human health. They are found in fish, seafood, and some plant-based oils. Omega-3 fatty acids are important for brain development, heart health, and immune function.
There are three main types of omega-3 fatty acids: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA). EPA and DHA are found in fish and seafood, while ALA is found in plant-based oils. The body can convert ALA into EPA and DHA, but the conversion rate is low.
