What Does Potassium Do?
Potassium is a mineral that plays an important role in several body functions. It helps:
• muscles contract and move
• transmit nerve signals
• regulate blood pressure
Potassium also works with sodium to manage fluid balance in the body. Healthy eating styles have lower levels of sodium and include many potassium-rich foods, such as fruits, vegetables, beans, and low-fat or fat-free milk and yogurt.
