Aspartame on women's health.

Excerpt:
The study, which analyzed diet drink intake and cardiovascular health in almost 60,000 women participating in the Women’s Health Initiative Observational Study, found that compared to women who never or only rarely consume diet drinks, those who consume two or more a day are 30 percent more likely to have a cardiovascular event and 50 percent more likely to die from related disease.

"This is one of the largest studies on this topic, and our findings are consistent with some previous data, especially those linking diet drinks to the metabolic syndrome,” says Dr.Ankur Vyas, a fellow in cardiovascular disease at UI Hospitals and Clinics, and the lead investigator of the study.
