Reuters notes that past studies have showed that caffiene hinders the body's ability to process sugar.

Let's go through the list of the health problems sugary drinks have been linked to: strokes, premature birth, and genetic obesity, to name a few. And while more studies are now confirming a link between sugary drinks and diabetes, no one is quite sure where caffeine fits into the picture. 

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 caffeinanted 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 caffiene 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?
