WASHINGTON ( Dispatches) -- A new study has revealed that consuming at least one cup of coffee a day may reduce the risk of acute kidney injury (AKI) when compared to those who do not drink coffee.
Johns Hopkins Medicine Scientists have found that those who drank any quantity of coffee every day had a 15% lower risk of AKI, with the largest reductions observed in the group that drank two to three cups a day (a 22%-23% lower risk).
They used data from the Atherosclerosis Risk in Communities Study, an ongoing survey of cardiovascular disease in four U.S. communities, researchers assessed 14,207 adults recruited between 1987 and 1989 with a median age of 54. Participants were surveyed seven times over a 24-year period as to the number of 8-ounce cups of coffee they consumed per day: zero, one, two to three, or more than three. During the survey period, there were 1,694 cases of acute kidney injury recorded.
AKI, as described by the National Kidney Foundation, is a sudden episode of kidney failure or kidney damage that happens within a few hours or a few days. This causes waste products to build up in the blood, making it hard for kidneys to maintain the correct balance of fluids in the body.
