Omega-3 refers to a group of essential fatty acids that are important for human health. These fats are not produced by the body, so they must be obtained through diet. Common sources of omega-3 include fatty fish like salmon, mackerel, and sardines, as well as plant-based sources like flaxseeds and walnuts. Omega-3 fatty acids are known for their potential health benefits, including reducing inflammation and supporting heart health. They are also linked to improved brain function and may play a role in mental health. Regular consumption of omega-3 can contribute to overall well-being.
