Which of these foods is NOT a good source of potassium?

Bread is not considered a good source of potassium compared to the other options listed. While bread does contain some potassium, the levels are generally much lower than those found in avocados, bananas, and sweet potatoes, which are well-known for their high potassium content.

Potassium is an essential mineral that plays a vital role in various bodily functions, including maintaining fluid balance, nerve function, and muscle contractions. Foods like avocados and sweet potatoes are particularly rich in potassium, with avocados providing about 485 mg of potassium per serving and sweet potatoes offering approximately sweet potatoes flavor contribute to their status as potent potassium sources.

Bananas are famously known for their potassium levels, averaging about 422 mg of potassium in a medium-sized banana. This mineral-rich fruit is often recommended for those looking to increase their potassium intake.

In contrast, while bread offers some nutritional benefits, it is primarily made from grains, which do not have significant amounts of potassium. Thus, considering these facts, bread stands out as the least effective option for providing potassium.
