Yet another study confirms what people have been saying for ages: Stop drinking diet soda. Like, right now. Drinking just one 12-ounce can of an artificially sweetened fizzy drink per week can increase your risk of Type 2 diabetes by 33 percent, French researchers found. And given that most people don't stop at a single weekly serving, your real risk for diabetes could actually be much higher.

The study, which was announced Thursday and will be published in the American Journal of Clinical Nutrition, was conducted by France's National Institute of Health and Medical Research and covered 66,118 middle-aged women whose dietary habits and health were tracked from 1993 to 2007.

The results were unexpected. Though it's well-known that people who consume a lot of sugar are more likely to develop diabetes, the researchers found that participants who drank "light" or "diet" soft drinks had a higher risk of developing Type 2 diabetes than those who drank regular, sugar-filled sodas. Those who drank 100 percent natural squeezed fruit juices instead had no additional risk.

Thanks for sharing. The biggest reason I had this surgery was to get healthy. In addition to weight loss, I'm trying to cut out bad things like artificial sweeteners and MSG. FYI, I've heard that drinking fresh veg juice really helps with weight loss.
