People with chronic kidney disease can help lengthen their life expectancy by consuming more caffeine, suggest results of a study published in Nephrology Dialysis Transplantation. While previous research showed a positive relationship between caffeine intake and life expectancy in the general population, possibly due to a protective effect of caffeine on blood vessels, the association in people with kidney disease has been unknown until now.

Approximately 89 percent of U.S. adults drink coffee or other caffeinated beverages every day, and about 14 percent have chronic kidney disease.

This observational study involved 4,863 people from 1999 to 2010, using data from the National Health and Nutrition Examination Survey (NHANES). Compared with study participants with kidney disease who consumed less caffeine, those with a higher intake had a nearly 25 percent lower risk of death over the course of an average five-year follow-up, according to the researchers.
