Best Foods for Kidney Health

MAINTAINING KIDNEY HEALTH THROUGH PROPER NUTRITION


Your kidneys are vital organs that filter waste from your blood, regulate fluid balance, and maintain essential minerals like potassium and sodium. A kidney-friendly diet can help protect these important organs, especially for those managing kidney disease, on dialysis, or recovering from a kidney transplant.
