Foods rich in omega-3 fatty acids play a crucial role in maintaining mental health by supporting brain function and regulating mood. Omega-3s are found in sources like fatty fish, flax seeds, and walnuts, where they help reduce inflammation and promote neurogenesis. Research suggests that these fatty acids can alleviate symptoms of depression and anxiety, enhancing overall emotional well-being. Furthermore, omega-3s may also support cognitive function and protect against age-related mental decline. Regularly including omega-3-rich foods in one's diet can, therefore, contribute positively to both psychological and physiological aspects of mental health.
