Caffeine and Kidneys = Coffee Beans ❤ Red Beans

There is already good evidence that coffee is good for the liver and could decrease the incidence of cirrhosis. But at Kidney Week this year, we found out that there was a dose-dependent inverse association between caffeine consumption and early death in chronic kidney disease patients.
Miguel Bigotte Vieira, MD (Centro Hospitalar Lisboa Norte, in Portugal), and his colleagues examined the association of caffeine consumption with mortality among 2328 patients with CKD in a prospective US cohort, using the continuous National Health and Nutrition Examination Survey (NHANES) 1999-2010.
Again this is an observational study but really exciting in that there may be a protective effect and is hypothesis generating for a future prospective study
