Consuming coffee is associated with lower risks of developing chronic kidney disease, reaching end-stage kidney disease, and having albuminuria.
In this systematic review and meta-analysis, researchers conducted a comprehensive literature search through various databases, including PubMed/Medline, Web of Science, Embase by Elsevier, and the Cochrane Central Register of Controlled Trials by Wiley from 1960 until February 2020. Outcomes related to chronic kidney disease incidence, its progression, and mortality associated with this disease were evaluated and correlated with coffee consumption and the amount consumed. Quality assessment of the included studies was done using the Newcastle-Ottawa scale.
The analysis incorporated 12 studies, with a mix of prospective and cross-sectional studies, and a total of 505,841 subjects. Seven of these studies focused on the relationship between coffee consumption and the onset of chronic kidney disease. The finding was that consuming coffee was significantly correlated with a decrease in the risk for this disease, especially for individuals who took more than 2 cups of coffee per day. Furthermore, there was also a noteworthy lower risk of reaching end-stage kidney disease for coffee drinkers, as well as a decrease in the risk of albuminuria (a kidney disease marker). Finally, the risk of death related to chronic kidney disease was discovered to be lower in coffee consumers.
