Almost everyone loves this drink.<\/p>\nAlmost everyone loves this drink.<\/p>\n
But it\u2019s been quite controversial throughout the years. Some studies say it\u2019s healthy, others it\u2019s not.<\/p>\n
However, a new study published in the journal Kidney International clearly reveals that, at least for your kidneys, this drink is heaven-sent.<\/p>\n
What is already known about the relationship between coffee and kidney disease?<\/p>\n
Daily coffee consumption leads to a lower risk of chronic kidney disease (CKD). This was the conclusion of a 2018 study in the American Journal of Medicine.<\/p>\n
The researchers analyzed the medical records of 8,717 Korean adults and discovered that daily coffee drinkers had a 24% lower risk of developing CKD than non-drinkers of this beverage.<\/p>\n
But the new study in Kidney International Reports did not study CKD, but rather the relationship between coffee drinking and acute kidney injury.<\/p>\n
Acute kidney injury is widely believed to be a temporary condition in which your kidneys stop working. Once it\u2019s been treated, it is over and kidney function is restored to normal.<\/p>\n
However, these widespread beliefs are actually wrong.<\/p>\n
A recent study in Nephron Clinical Practice discovered that acute kidney injury was a risk factor for CKD, both in cases where it was inadequately treated and in cases where it was treated appropriately.<\/p>\n
So, if acute kidney injury is a risk factor for the development of CKD, then what effect does coffee consumption have on acute kidney injury?<\/p>\n
This is the question the new study in Kidney International Reports investigated.<\/p>\n
The authors mined data from the Atherosclerosis Risk in Communities study in which 14,207 adults between 45 and 64 years reported their coffee consumption.<\/p>\n
Researchers also collected information about acute kidney injury by checking which of them were hospitalized with an acute kidney injury-related International Classification of Diseases code.<\/p>\n
What did this comparison show?<\/p>\n
1. Compared with non-drinkers, those who drank less than one cup or one cup a day had an 8% lower risk of acute kidney injury.<\/p>\n
2. Compared with non-drinkers, those who drank two or more cups a day had a 17% lower risk.<\/p>\n
The researchers excluded all other possible causes of acute kidney injury from influencing their findings, such as diet, blood pressure, diabetes, and body weight.<\/p>\n
