Potassium: The Antidote to Too Much Sodium

Find out which foods can boost potassium levels and help balance sodium intake.

While itโ€™s well-known that too much sodium can raise blood pressure, the benefits of potassium are often overlooked.

Increasing potassium intake relative to sodium may be a more effective way to lower blood pressure than just cutting back on sodium. Potassium-rich foods help maintain healthy blood vessels and reduce sodiumโ€™s negative effects.

Melissa Stadt, a researcher who studied potassium-to-sodium intake and recently published a study, told The Epoch Times that early humans ate plenty of fruits and vegetables, so the bodyโ€™s regulatory systems function best on a high-potassium, low-sodium diet.

โ€œToday, Western diets tend to be much higher in sodium and lower in potassium. That may explain why high blood pressure is found mainly in industrialized societies, not in isolated societies,โ€ she said.

Potassium to Manage Blood Pressure

The sodium-to-potassium ratio in the diet is a better predictor of blood pressure, heart disease risk, and even overall mortality than sodium or potassium alone.

High sodium intake can cause the body to retain fluid, which increases blood volume and puts extra pressure on blood vessel wallsโ€”leading to elevated blood pressure and increased strain on the heart.

Sodium and potassium levels are tightly regulated by the kidneys. When you eat a potassium-rich meal, the kidneys initially reabsorb less sodium, allowing more sodium to flow downstream. This shift in kidney function promotes the excretion of sodium in the urine, affecting water movement and blood volume, which lowers blood pressure. Recent findings presented at a meeting of the American Physiological Society in Baltimore further supported this mechanism, showing that potassium can counteract the effects of a high-sodium diet by encouraging sodium excretion.

The studyย also focused on a lesser-known benefit: Potassium may support blood vessel health even in people whose blood pressure isnโ€™t affected by salt. These so-called salt-resistant people donโ€™t experience a rise in blood pressure when they eat more sodiumโ€”yet when their potassium intake increased, their blood vessels functioned better, showing an improved ability to relax and widen.

โ€œBoosting potassium intake may be a critical strategy for improving blood vessel health and lowering long-term risk,โ€ Shannon Lennon, a co-author of the study who has a doctorate in exercise physiology and is a professor at the University of Delaware, told The Epoch Times.
