2-3 cups of coffee a day may reduce kidney injury risk by almost a quarter

Coffee consumption is linked to numerous health benefits, including a reduced risk of type 2 diabetes, as well as liver, heart, and neurological diseases. Now, new research suggests we can also add kidney protection to that list.


According to the study, the results of which are published in Kidney International Reports, people who regularly drink coffee have a reduced risk acute kidney injury. However, the benefits are most apparent in those who drink 2-3 cups of coffee each day.


For the study, the team of researchers used data from 14,207 adults ages 45-64 from the Atherosclerosis Risk in Communities (ARIC) study.


The researchers asked the participants to disclose information relating to how much coffee they drank. The results were: 




  • 27% never drank coffee




  • 14% drank less than a cup of coffee per day




  • 19% drank 1 cup per day




  • 23% drank 2-3 cups per day




  • 17% drank more than 3 cups per day




After adjusting for demographic factors, the researchers found that participants who consumed any amount of coffee had an 11% lower risk of developing acute kidney injury than those who did not drink coffee.


The researchers further noted a that those consuming 2-3 cups of coffee per day experienced the most substantial risk reduction (23%)
