WASHINGTON DC. [USA]It turns out that consuming more caffeine can help reduce the risk of death in people with chronic kidney disease.
In a new study, the researchers hypothesized that caffeine consumption might be associated with lower mortality in participants with chronic renal failure. The possible protective effect of caffeine could be related to vascular effects, since caffeine is known to promote the release of substances, such as nitric oxide, which improves the functioning of the vessel.
Chronic kidney disease is associated with increased health care costs and a higher risk of death. The prevalence of the disease is expected to continue to increase worldwide.
Miguel Bigotte Vieira, one of the main authors of the study, said: "Our study showed a protective effect of caffeine consumption in patients with chronic renal failure. smoking and diet. "
"These findings suggest that advising patients with renal impairment to drink more caffeine can reduce their mortality, which would be a simple, clinically beneficial and inexpensive option, although this benefit should ideally be confirmed in a randomized clinical trial. ", added Vieira.
The author therefore pointed out that this observational study can not prove that caffeine reduces the risk of death in patients with chronic renal failure, but only suggests the possibility of such a protective effect.
The complete results are present in the review – Nephrology Dialysis Transplantation.
