A new study concludes that there could be negative consequences associated with artificial sugar substitutes -- including a much higher risk of strokes.
The study is somewhat controversial; some critics have argued that since the participants voluntarily reported how much diet soda they consumed, the results do not come from a rigorously controlled setting.
According to the Seattle Post Intelligencer:
"Researchers used voluntary participants to examine factors related to stroke and heart attacks. About 900 participants said they drank no diet soda, and about 160 said they consumed more than one diet soda every day."
