A new study that followed more than 100,000 Americans for more than 20 years, reports Reueters, showed that those who drank sugary drinks were 23 percent more likely to develop type 2 diabetes. But the research on caffeinated sugary drinks was unclear: those who drank caffeinated sugary drinks, compared to those who drank none, still had a 13 percent chance of developing diabetes. Those who drank non-caffeinated sugary drinks also had a higher risk of diabetes, at 6 percent.

Reuters notes that past studies have showed that caffeine hinders the body’s ability to process sugar. However, those who drank coffee and tea had a lower risk of developing diabetes; at 8 percent lower for female coffee drinkers and 4 percent lower for male coffee drinkers. That may further prove the benefits of coffee and tea to prevent diabetes. A study this month showed that countries with higher rates of black tea (a caffeinated tea) consumption had lower rates of type 2 diabetes. Is caffeine the miracle elixir for diabetes — or is it the properties of coffee and tea?
