Proper nutrition plays a significant role in mental health, and deficiencies in certain nutrients can contribute to depression and suicidal thoughts. Omega-3 fatty acids, found in fish, flaxseeds, and walnuts, are particularly important for brain health. Low levels of these fatty acids have been linked to increased risk of depression and suicidal behavior. Ensuring a diet rich in essential nutrients can help support mental well-being and reduce the risk of suicide.
