If dehydrated, which foods are encouraged?

• A. High potassium foods
• B. High sugar foods
• C. High fat foods
• D. Low potassium foods

Answer: (A)

When someone is dehydrated, restoring fluid and electrolyte balance is essential. Potassium is a key electrolyte lost with dehydration and is vital for proper muscle function, nerve signaling, and heart rhythm. Replacing potassium helps re-establish electrical stability in the body as fluids are replenished, so choosing foods that are rich in potassium supports the rehydration process more effectively than foods that don’t address this electrolyte deficit.

High sugar foods don’t meaningfully aid rehydration and can even draw water into the gut, slowing recovery. High fat foods can slow digestion and aren’t helpful for quick fluid and electrolyte replacement. Low potassium foods won’t help correct the electrolyte imbalance that accompanies dehydration. Therefore, prioritizing potassium-rich foods is the best approach to support rehydration, with the caveat that certain medical conditions or medications that affect potassium levels may require individual adjustments.
