Potassium is essential for many bodily functions; it maintains fluid levels inside our cells, aids blood pressure control, and supports muscle contractions. Many foods contain a lot of potassium, including fruits, vegetables, and meats. So, if you're seeking to increase your potassium intake, it's relatively easy to design a diet.
However, people suffering from kidney disease may need to limit their potassium intake, which can prove more difficult. They must be aware of the potassium contents of different foods, limiting their intake or excluding them from their diets entirely.
This can be especially difficult with delicious snack foods like popcorn.

How Much Potassium Is in Popcorn?
The recommended daily potassium intake is around 3,000 milligrams for most adults. One ounce of air-popped popcorn contains about 93 mg of potassium, and the same-sized serving of microwaved contains about 51 mg.
The potassium content of popcorn varies with the brand, cooking method, and where the corn was grown. For example, kettle-popped contains more potassium than air-popped, and corn grown in volcanic soils contains more than that from other areas.
