Nutrition plays a vital role in supporting mental cognitive function by providing essential nutrients necessary for optimal brain health. Key nutrients, such as omega-3 fatty acids, antioxidants, and vitamins, are crucial for maintaining neuronal function, promoting neurogenesis, and protecting against cognitive decline. A balanced diet rich in fruits, vegetables, whole grains, and healthy fats can enhance memory, focus, and overall cognitive performance. Conversely, poor dietary choices may lead to cognitive impairments and mental health issues like depression and anxiety.
