Question: 1 / 400

Which nutrient is important for regulating body temperature?

Protein

Fats

Water

Water is crucial for regulating body temperature due to its unique properties as a solvent and its high specific heat capacity. The body uses water in processes such as sweating, where the evaporation of sweat from the skin surface helps to cool the body when heat levels rise. This thermoregulation is essential for maintaining homeostasis, particularly during physical activity or in high-temperature environments.

While protein, fats, and carbohydrates are all vital nutrients contributing to the body’s overall functioning, they do not play a direct role in thermoregulation like water does. Proteins participate in building and repairing tissues, fats provide energy and insulation, and carbohydrates are primarily used for quick energy. These functions are important but do not influence the regulation of body temperature in the same way that water does.
