A good source of omega-3 fatty acids includes fatty fish such as salmon, mackerel, and sardines. These fish are rich in EPA and DHA, two important components of omega-3s that contribute to heart health and reduce inflammation in the body. Plant-based sources, such as flaxseeds, chia seeds, and walnuts, provide alpha-linolenic acid (ALA), another type of omega-3. Incorporating these foods into the diet can support a variety of health benefits, including improved cardiovascular function.
