5 things you may not have known about coffee ("Do not miss" system)
Coffee is the most popular drink in the world and many are not satisfied with one glass of it and drink several a day.
Now scientists from the Johns Hopkins Bloomberg School of Public Health have found that drinking two cups of coffee a day may pose a higher risk of developing chronic kidney disease.
The new study, published in the Clinical Journal of the American Society of Nephrology, examined 372 blood metabolites among 3,811 different people.
Metabolites are small molecules that are produced or used when the body breaks down food, drugs or chemicals.

The findings showed that 56 percent of the people surveyed by the researchers drank coffee daily, and 32 percent drank more than two glasses a day.
During their tests, the researchers discovered one metabolite associated with coffee that can help the kidneys become healthier.
However, alarmingly, they also found two other metabolites associated with chronic kidney disease.

Chronic kidney failure involves the gradual loss of kidney function.
Damaged kidneys cause the accumulation of toxic waste, which can lead to hypertension, heart disease and stroke.
In addition, it may require the start of dialysis or a kidney transplant.

The new findings "surprised" Johns Hopkins researchers, given that a report published just six months ago concluded that there was a "beneficial effect of coffee on kidney function."
Dr. Casey Rabholtz, one of the authors of the new study, told The Independent that one of the coffee-related metabolites that has also been linked to kidney disease also contains cigarette-related compounds.
In addition, a plethora of other studies have established that coffee can be beneficial to a person’s overall health.
In June, findings published in the medical journal BMC Public Health found that consuming three to four cups of coffee a day may reduce the risk of liver cancer and other alcohol-related liver diseases.
A study published last September found that drinking up to three cups of coffee a day can protect the heart.
The study found that among people without a diagnosis of heart disease, regular coffee consumption of half to 3 cups of coffee a day was associated with a reduced risk of death from heart disease, stroke and early death for any reason compared to drinking other beverages.
