According to a study published in the journal Nephrology Dialysis Transplantation, drinking coffee may help reduce the risk of death for people with chronic kidney diseases. Comparing with people that consumed less caffeine, patients that consumed higher levels of caffeine presented a nearly 25 percent reduction in the risk of death over a median follow-up of 60 months. The possible positive effects of caffeine might be related with effects at vascular levels as caffeine is known to promote the release of substances, such as nitric oxide, that improve the function of the vessel.
As per the researchers, the 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," Vieira added.
For the study, described in the journal Nephrology Dialysis Transplantation, the team involved data from 4,863 people. However, the researchers emphasised that this observational study cannot prove that caffeine reduces the risk of death in patients with chronic kidney disease, but only suggests the possibility of such a protective effect.
