We love this drink so much that thousands of studies have been done about it. It has been labeled the worst killer or the greatest health savior.
So which is true regarding chronic kidney disease?
According to a new study published in the Journal of Renal Nutrition, this drink is extremely beneficial.
The research team led by Turkish scientists from Koc University School of Medicine in Istanbul and Suleyman Demirel University School of Medicine in Isparta noticed previous research that concluded that coffee could combat inflammation, fight harmful oxidation, stop scar tissue from forming in organs, and prevent unnecessary blood clotting.
They also noticed previous research on the link between coffee consumption and chronic kidney disease. So they decided to conduct a literature review to check whether most of the available research supported the effectiveness of coffee against this disease.
They searched medical databases for studies from 1960 to February 2020 and found 12 studies with 505,841 participants. None of the studies were randomized double-blind trials, the strongest form of research that exists.
It turned out that drinking coffee could reduce the subjects’ risk of chronic kidney disease by 14%, reduce their chance of reaching end-stage kidney disease by 18%, and reduce albuminuria by 19%.
Albumin is an important protein, but it should be in your blood, not your urine. If it is in your urine, it is called albuminuria and may indicate that you have kidney disease.
Coffee drinkers were also 28% less likely than those who consumed little coffee to die of kidney disease.
All of this was true for people who drank two or more cups of coffee per day, as compared with people who drank one or fewer cups per day.
The National Kidney Foundation does warn that you should keep your coffee consumption at a moderate level if you already have kidney disease, especially if you struggle with blood pressure control. Caffeine can lead to a short-term spike in blood pressure that can damage your kidneys.
