t is estimated that 30 million U.S. adults have “chronic kidney disease” (CKD), a progressive condition in which the kidneys gradually lose their ability to filter water and waste products from the blood. Over time, CKD may progress to kidney failure (or end-stage renal disease), making kidney transplantation or dialysis the only treatment options. While CKD remains a leading cause of death in this country, recent research points to a way for CKD patients to improve their chances of survival—drink more coffee. According to a recent study, researchers found that CKD patients who consumed the highest amounts of caffeine cut their mortality risk by almost a quarter compared with those who consumed the lowest amounts.
P.S. According to the study mentioned above, study participants who consumed 206.5 to 1,378.5 milligrams of caffeine daily saw the most benefit. The average caffeine content of an 8-oz. brewed cup of coffee is 95 mg.
