Dietary factors that can contribute to improving mental health include consuming a balanced diet rich in omega-3 fatty acids, fruits, vegetables, and whole grains. These foods provide essential nutrients that support brain function and reduce the risk of mood disorders. For instance, folate found in leafy greens and beans has been linked to improved mood, while antioxidants, found in berries, can protect brain health. Limiting processed foods, added sugars, and trans fats is also beneficial for maintaining mental well-being.
