Which of the following nutrients helps improve mental performance?

The correct answer is that all of the nutrients listed—carbohydrates, water, and fats—contribute to improving mental performance in various ways.

Carbohydrates are crucial because they are a primary source of energy for the brain. Glucose, derived from carbohydrates, is the brain's preferred fuel. Adequate carbohydrate intake can enhance cognitive functions, including memory and attention, helping to keep mental performance at its peak.

Water is essential for overall cognitive function and mental clarity. Even slight dehydration can lead to decreased focus, memory issues, and mood changes. Staying hydrated supports various physiological processes, allowing the brain to function optimally.

Fats, particularly omega-3 fatty acids, play a vital role in brain health. These types of fats are important for the structure of brain cells and are involved in neurotransmission. Adequate fat intake supports cognitive functions and can even influence mood positively.

Together, these nutrients support different aspects of brain function and overall mental performance, highlighting their collective importance in a balanced diet.
