More recently , a study found that drinking soda habit increases the risk of kidney disease . The clerks at a university in Japan who consumed two glasses of fizzy drinks a day tend to have protein in urine than those who drink less or not drink soda at all .

The new study shows the link between drinking soda and an increased risk of kidney damage . However, the researchers did not just make fizzy drinks as the only " black sheep" .
In the study , the researchers analyzed data on more than 12,000 university employees who conduct annual health examinations at the health center . One type of examination is protein in the urine .
