American scientists recently wrote in the International Kidney Report that drinking coffee is associated with a reduced risk of acute kidney injury (AKI): drinking coffee every day can reduce the risk of AKI by 15%; drinking two to three cups of coffee a day reduces the risk. 22%-23%.
"We already know that regular coffee consumption protects against chronic and degenerative diseases, including type 2 diabetes, cardiovascular disease and Liver disease, and now there's one more -- it can reduce the risk of AKI."
In the latest study, Parikh's team analyzed data from the American Atherosclerosis Risk in Communities (ARIC) study, which included 14,207 participants aged 45 to 64, with an average age of 54 age. They counted all participants' basic information such as age, gender, height, weight, diet, history of treatment for chronic diseases such as hypertension. Over a 24-year period, participants were surveyed seven times about their daily coffee consumption: 0 cups, 1 cup, 2 to 3 cups, or more than 3 cups. During the investigation period, the researchers recorded a total of 1694 cases of AKI.
Results showed that, overall, coffee-drinking participants had a 15% lower risk of developing AKI than non-coffee drinkers, after accounting for demographic characteristics, socioeconomic status, lifestyle influences, and dietary factors. Drinking two to three cups of coffee a day was associated with a more significant reduction in AKI risk—22% to 23%.
The researchers explained that coffee's lower risk of developing AKI may be related to the bioactive compounds contained in coffee, or simply because of the caffeine itself. Caffeine is thought to inhibit the production of molecules that cause chemical imbalances and the excess use of oxygen in the kidneys, so it may help the kidneys maintain a steady state.
