Fructose: Sugar's Dark Side?
Study: Fructose Increases Heart Risk Factors -- and Weight
"Most people get the majority of the added sugars in their diet from beverages," Havel tells WebMD. "We saw a lot of changes happen in just two weeks of drinking these beverages -- and in real life, people don't do this just for two or 10 weeks but as a lifelong habit. They are potentially exposing themselves to cardiovascular risk."
The news may be worse. Stanhope says that preliminary data from new studies show that regular sugar and high-fructose corn syrup each seem to have the same effect as fructose alone -- even though both are only about half fructose and half glucose (normal corn syrup is 100% glucose).
It's still far too early to draw any conclusions from the new study. But Stanhope says it's unlikely anybody is going to apply the health-food label to sweetened soft drinks.
"It doesn't look like a good idea to drink a lot of soft drinks," Stanhope tells WebMD. "We were feeding people at the rate of three sodas a day. Some do drink that much, some people in real life do more, and some have only one a day. Give me two years, and we will know a lot more about the safe level."
Stanhope reported the findings at the American Diabetes Association's 67th Annual Scientific Sessions, held June 22-26 in Chicago.
