Does Diet Soda Raise the Risk of Stroke?

Yahoo.com reports that in a new study researchers found an elevated risk of stroke in those who drink diet soda on a regular basis over those who do not drink any soda at all.

Doctors have no chemical or biological explanation for why diet soda may be risky. It could be that people who drink lots of it also fail to exercise, weigh more, drink more alcohol or have other risk factors like high blood pressure and smoking. However, the researchers took these and many other factors into account and didn't see a change in the trend.

The study goes on to say that their proof is far from definitive but this should be a "wake up call" to those drinking diet soda. Health experts recommend water instead.
