Between 2013 and 2015, there has been some upward movement in the percentage of people who access social networks across many emerging countries. This is especially the case in China, where 63% of internet users report using social networking in 2015, up from 48% in 2013.
Background. 1  Carbonated beverage consumption has been linked with diabetes, hypertension, and kidney stones, all risk factors for chronic kidney disease. Cola beverages, in particular, contain phosphoric acid and have been associated with urinary changes that promote kidney stones.
The leading cause of kidney stones is a lack of water. Stones commonly have been found in those that drink less than the recommended eight to ten glasses of water a day. When there is not enough water to dilute the uric acid (component of urine), the pH level within the kidneys drops and becomes more acidic. An excessively acidic environment in the kidneys is conducive to the formation of kidney stones. Medical conditions such as Crohn's disease, urinary tract infections, renal tubular acidosis, hyperparathyroidism, medullary sponge kidney, and Dent's disease have been known to lead to kidney stones.
