<human>:  What is the relationship between diet and depression?
<bot>: The relationship between diet and depression is an emerging area of research. Studies have suggested that a diet rich in nutrients such as omega-3 fatty acids may be beneficial for improving mood, and that poor nutrition can worsen depression symptoms. Additionally, a diet high in processed and sugary foods may increase the risk of depression. Eating regular meals and avoiding certain foods such as refined grains, alcohol, and processed foods that may worsen symptoms of depression is recommended.
