Which dietary sources are rich in potassium?

The option identifying bananas, oranges, potatoes, and spinach as rich dietary sources of potassium is accurate because these foods have a high potassium content, which is essential for various bodily functions. Potassium plays a critical role in maintaining proper electrolyte balance, nerve function, and muscle contraction.

Bananas are well-known for their potassium content, with a medium banana providing about 422 mg of potassium. Oranges and orange juice are also significant sources, contributing approximately 237 mg of potassium in a medium orange and more in a cup of juice. Potatoes, especially when cooked with their skins, can provide even more potassium—around 926 mg for a medium baked potato. Spinach, whether raw or cooked, is another excellent source, offering approximately 839 mg per cooked cup.

In contrast, other food options listed do not provide comparable amounts of potassium. For example, while apples, carrots, and grapes contain some potassium, they do not match the levels found in the foods listed in the correct option. Similarly, rice, bread, and pasta mainly offer carbohydrates and are generally lower in potassium. Chicken, fish, and eggs provide some potassium, but they are not as potassium-rich as the fruits and vegetables mentioned. This distinction highlights the importance of focusing on
