Which of the following foods is highest in potassium?

Potatoes are indeed the food option with the highest potassium content among those listed. Potassium is a vital mineral that plays a key role in muscle contractions, nerve function, and maintaining fluid balance in the body.

When considering the potassium content in these foods, potatoes stand out, particularly when baked with the skin on, which enhances their nutrient profile. A typical medium-sized potato (about 150 grams) can have around 620 mg of potassium or more, depending on the variety.

In contrast, while apples, berries, and peaches do contain potassium, their levels are significantly lower. A medium apple has about 195 mg of potassium, a cup of berries ranges from 150 to 300 mg depending on the type, and a medium peach has roughly 300 mg. None of these options provide the same high concentration of potassium found in potatoes, making potatoes the best choice for anyone looking to increase their potassium intake through food sources.
