In the current study, however, adults who routinely consumed at least one can of soda or other sugar-sweetened beverages a day were 46 percent more likely to develop elevated blood sugar levels than people who rarely or never drink cola. β€œFor daily consumers of sugary drinks, kicking the habit may be a difficult challenge, and incorporating an occasional diet soda, while increasing fluids from other sources, may be the best strategy to ultimately remove sugar-sweetened beverages from the diet,” McKeown added by email.
