Nutrition plays a crucial role in mental health by affecting brain function and mood regulation. A balanced intake of essential nutrients, such as omega-3 fatty acids, B vitamins, and antioxidants, supports cognitive function and emotional well-being. Poor nutrition can lead to increased feelings of anxiety and depression, while a nutrient-rich diet can enhance mood stability and cognitive performance. Incorporating whole foods, including fruits, vegetables, whole grains, and lean proteins, is vital for optimal brain health and overall psychological resilience.
