What are the health benefits of potassium?

Potassium is an important mineral with numerous functions. Potassium is needed in your body for fluid balance, muscle contraction, and for your nerve impulses to work properly.

Research also suggests that a diet plentiful in potassium lowers blood pressure, especially in salt-sensitive individuals who respond more intensely to sodium’s blood pressure -- raising capabilities. Potassium helps negate some of the blood pressure-raising effects of excessive dietary sodium as it causes the kidneys to excrete excess sodium from the body. Reducing sodium levels in the body helps lower blood pressure.

The good news is that potassium is found in a variety of foods, with vegetables, fruits, low fat dairy foods, and beans being potassium powerhouses.
