Which food is a good source of potassium?

• A. Bananas
• B. Apples
• C. White rice
• D. Salt substitutes

Answer: (A)

Potassium supports cellular function, nerve signaling, and muscle contraction, including the heartbeat, so choosing foods rich in potassium helps meet daily needs. A medium banana contains about 400–450 mg of potassium, making it a strong and convenient dietary source. Apples have less potassium per serving, and white rice provides only a small amount. Salt substitutes do contain potassium, but they’re not a typical primary food source and should be considered with individual health and medication considerations in mind.
