The relationship between diet and mental health is significant, as certain foods can influence mood, cognitive function, and overall psychological well-being. Diets rich in omega-3 fatty acids, whole grains, fruits, and vegetables have been linked to reduced symptoms of anxiety and depression. Conversely, excessive intake of processed foods, sugars, and unhealthy fats may negatively impact mental health. Nutritional deficiencies, particularly in B vitamins and minerals, can also affect mood. Therefore, maintaining a balanced diet is crucial for supporting both physical and mental well-being.
