Coffee is a complex mixture of many chemical compounds, some of which may have beneficial effects on health, including kidney health. Some observational studies associate drinking more coffee to a lower risk of developing chronic kidney disease among coffee drinkers. Consuming more coffee seems to have a protective affect against kidney disease. Further study is needed to determine whether a coffee-based intervention is effective for prevention or treatment of kidney disease. Those struggling with blood pressure management should drink less than three cups of coffee per day.
