Potassium rich foods keep the heart healthy by lowering blood pressure, keeping heart rhythm steady, and reducing risk of cardiac arrest.

2. How does potassium affect the cardiovascular system?

Potassium helps keep your heart beating at the right pace. It does this by helping to control the electrical signals of the myocardium -- the middle layer of your heart muscle. When your potassium level is too high, it can lead to an irregular heartbeat.

Your total intake of potassium should not be greater than the recommended amounts, unless ordered by your doctor. In some cases, too much potassium may cause muscle weakness, confusion, irregular heartbeat, or difficult breathing.
