A common dietary source of omega-3 fatty acids is fatty fish, such as salmon, mackerel, and sardines. These fish contain high levels of EPA and DHA, essential components that support heart, brain, and joint health. Other sources include flaxseeds, chia seeds, and walnuts, which provide alpha-linolenic acid (ALA), a plant-based omega-3. Incorporating these foods into the diet can help individuals meet their omega-3 needs and gain associated health benefits, such as reduced inflammation and improved cardiovascular function.
