Which food is highest in potassium among common choices?

• A. Oranges
• B. Bananas
• C. Apples
• D. Grapes

Answer: (B)

Potassium content in foods depends on the food and the serving size, so comparing typical portions is how you determine which is highest. Among common fruits, banana stands out because a medium banana contains roughly 400–450 mg of potassium, which is higher than the amounts in a medium orange (about 230–250 mg), an apple (around 180–200 mg), or a cup of grapes (roughly 250–300 mg). While grapes can be relatively high per cup, the banana’s potassium per usual serving is generally the greatest. So the banana is the highest potassium option here.
