A balanced diet plays a vital role in maintaining mental well-being. Nutrient-rich foods, especially those high in omega-3 fatty acids, vitamins, and minerals, support brain function and mood regulation. Poor nutrition, on the other hand, can contribute to fatigue, irritability, and depressive symptoms. Diets high in processed food or sugar may increase inflammation and affect mental clarity. Eating whole grains, fruits, vegetables, and lean proteins promotes stable energy and emotional balance. Hydration and mindful eating also improve focus and reduce stress. Nutrition should complement therapy and other treatments for optimal mental health.
