Which statement is true about water?

• A. It is the one essential nutrient no person can live without
• B. It is optional for hydration
• C. It provides calories
• D. It can be stored as fat

Answer: (A)

Water is an essential nutrient needed for life itself. It supports every cell and organ, helps regulate body temperature, aids digestion, transports nutrients, and removes wastes. Because the body doesn’t store water for long-term use, we must continually replace it through drinking and foods with high water content to stay properly hydrated. Water contains no calories, so it does not provide energy. The body also does not store water as fat; fat stores energy from calories, not from water. Hydration isn’t optional—you need regular fluid intake to stay hydrated, even though you can get fluids from a variety of beverages and foods. In short, water is the one essential nutrient no person can live without.
