What is the primary dietary source of potassium?

While bananas are often associated with potassium due to their promotion as a potassium-rich food, potatoes are actually considered the primary dietary source of potassium when comparing these options. Potatoes contain higher levels of potassium per serving than bananas, making them a significant contributor to dietary potassium intake. Additionally, potatoes are a staple food in many diets around the world, and their versatility in preparation makes them accessible as a potassium source.

Bananas do provide a good amount of potassium and are commonly known for it, but they do not surpass the potassium content found in potatoes. Other options, such as oranges and spinach, also contain potassium, but to a lesser extent compared to potatoes. Therefore, while bananas are indeed a popular source, potatoes are the richer and more substantial primary dietary source of potassium.
