As per the study published in Nephrology Dialysis Transplantation, consuming more caffeine may help to reduce the risk of death due to chronic kidney disease.

The research also states that caffeine consumption might be associated with lower mortality among participants with chronic kidney disease.

The protective effect of caffeine might be related to effects at vascular level. Apart from it, caffeine has a substance called nitric oxide that improves the function of the vessel.

The study involved data from 4,863 American people observed from 1999 to 2010. It compared with people who consumed less caffeine-containing beverages, caffeine consumers were more likely to be male, non-Hispanic white, have a higher education level and higher annual income, be current or former smokers, have higher alcohol consumption, and have fewer previous strokes.

The results of the analysis show an inverse association between caffeine consumption and all-cause mortality among participants with chronic kidney disease. Comparing with people that consumed less caffeine, patients that consumed higher levels of caffeine presented a nearly 25% reduction in the risk of death over a median follow-up of 60 months.

“Our study showed a protective effect of caffeine consumption among patients with chronic kidney disease. The reduction in mortality was present even after considering other important factors such as age, gender, race, smoking, other diseases, and diet. These results suggest that advising patients with kidney disease to drink more caffeine may reduce their mortality. This would represent a simple, clinically beneficial, and inexpensive option, though this benefit should ideally be confirmed in a randomized clinical trial.”, said Miguel Bigotte Viera, study’s lead author.
