What is Potassium?
Potassium is an essential mineral and electrolyte that carries an electrical charge. It's the primary positive ion inside cells and is critical for maintaining proper fluid balance, nerve transmission, and muscle contraction.
Blood Pressure Regulation
Potassium works in opposition to sodium. While excess sodium raises blood pressure, adequate potassium helps lower it by promoting sodium excretion and relaxing blood vessel walls. The potassium-to-sodium ratio in your diet matters more than absolute amounts.
Muscle and Heart Function
Every heartbeat depends on potassium. This mineral helps generate the electrical impulses that make your heart contract rhythmically. Both low and high potassium levels can cause dangerous heart arrhythmias.
The Potassium Gap
Most people consume far less potassium than recommended—often less than half. This is partly because processed foods are typically high in sodium but low in potassium, while whole foods like fruits and vegetables are potassium-rich.
Food Sources
Bananas are famous for potassium, but many foods contain more: potatoes, sweet potatoes, beans, spinach, avocados, and salmon are excellent sources.
