Know Why Potassium Is So Important

Potassium, an essential mineral and electrolyte, regulates the balance of fluids and minerals in cells and also works to maintain heart and kidney function and a healthy blood pressure. This mineral is also key to boosting your metabolism because it is required to make your muscles contract and because it helps convert blood sugar into glycogen. Glycogen is stored in your muscles and liver and later burned for energy. Though a potassium deficiency is uncommon, it can be caused by kidney disease, chronic diarrhea, vomiting, or the overuse of laxatives and diuretics. Good sources for the mineral include bananas, beans, spinach, sweet potatoes, papaya, and Swiss chard.
