Which food group is the highest source of potassium?

The highest source of potassium among the food groups is fruits and vegetables. This group includes a variety of potassium-rich foods such as bananas, oranges, potatoes, spinach, and avocados, which are renowned for their high potassium content. Potassium is an essential mineral that plays a crucial role in maintaining fluid balance, nerve function, and muscle contractions.

While the other food groups do contain some potassium, they do not match the overall levels found in fruits and vegetables. Dairy products provide a good amount of potassium, but not as much as the diverse array found in fruits and vegetables. Cereals can contribute to potassium intake, especially whole grain varieties, but they are still not as significant as fruits and vegetables. Meat and fish also have potassium, particularly certain types like salmon and halibut, but they are generally less than what is provided by a varied diet of fruits and vegetables.

Thus, the prominent range of potassium-rich options available in the fruits and vegetables category makes it the best choice for the highest source of potassium among the food groups listed.
