Certified Hemodialysis Technician Practice Exam

Question: 1 / 400

Which fruit is known for being high in potassium?

Apples

Bananas

Bananas are widely recognized for their high potassium content. Potassium is an essential mineral that plays a crucial role in various bodily functions, including maintaining proper fluid balance, nerve signaling, and muscle contractions. A medium-sized banana typically contains about 422 mg of potassium, making it one of the best sources of this important nutrient.

While other fruits, like apples, berries, and grapes, do contain potassium, their levels are significantly lower compared to bananas. For instance, a medium apple has around 195 mg of potassium, and a cup of berries can provide approximately 150 mg. Grapes also contain potassium, but again, not to the extent found in bananas. This high potassium content is one of the reasons bananas are recommended as a beneficial fruit, particularly for individuals seeking to manage their electrolyte levels and support cardiovascular health.
