Omega-3 fatty acids play a vital role in overall health by promoting cardiovascular health, reducing inflammation, and supporting brain function. Commonly found in fatty fish, flaxseeds, and walnuts, omega-3s can help lower blood pressure, improve cholesterol levels, and reduce the risk of heart diseases. They are also beneficial for mental health, potentially alleviating symptoms of anxiety and depression, making them an essential component of a balanced diet for both physical and mental well-being.
