Fatty fish, such as salmon, sardines, and mackerel, are known to be rich in omega-3 fatty acids. These essential fats are crucial for maintaining cardiovascular health, supporting brain function, and reducing inflammation. Plant-based sources like flaxseeds, chia seeds, and walnuts also provide omega-3s, mainly in the form of ALA (alpha-linolenic acid). Incorporating these foods into the diet can help ensure adequate intake of omega-3s, which are vital for overall health and well-being.
