Which of the following nutrients helps the body maintain normal fluid balance?Multiple ChoicePotassiumFluorideIronCopper

1. Break Down the Problem

We need to identify which of the listed nutrients plays a role in maintaining normal fluid balance in the human body.

2. Relevant Concepts

Fluid balance in the body is often regulated by electrolytes, which are minerals that carry an electric charge when dissolved in water. Key electrolytes include sodium, potassium, calcium, magnesium, and chloride.

3. Analysis and Detail

• Potassium: Recognized as a crucial electrolyte that helps regulate fluid balance and is vital for cell function. It works closely with sodium to maintain blood pressure and fluid levels in cells.
• Fluoride: Primarily important for dental health and does not play a significant role in fluid balance.
• Iron: Essential for oxygen transport in the blood but does not directly affect fluid balance.
• Copper: Important for various biological roles like iron metabolism and nervous system function, yet not directly involved in fluid regulation.

4. Verify and Summarize

Among the options provided, potassium is well-known for its critical role in maintaining normal fluid balance.

Final Answer

Potassium helps the body maintain normal fluid balance.
