Dietary patterns can influence mental health significantly. A balanced diet rich in omega-3 fatty acids, whole grains, and a variety of fruits and vegetables has been linked to lower rates of depression and anxiety. Adequate intake of essential nutrients, such as vitamins B and D, plays a crucial role in brain function and mood regulation. Conversely, diets high in processed foods and refined sugars may exacerbate mental health issues. Overall, a nutritious diet contributes to improved brain health and emotional well-being.
