Usually the research reviewed here is published in national or international medical journals. The research reviewed this time was however presented at a recent international stroke conference (Anwar Z, et al. 2011). The study was both interesting and surprising and for that reason you should know about it.
The researchers investigated the association between drinking soda, both diet soda and regular soda and the risk of strokes in 3, 298 participants. The average follow up was 9.3 years during which 559 vascular events occurred.
It was documented that the subjects who drank diet soda everyday had a 61% higher risk of ischemic or hemorrhagic stroke when compared to those who did not drink any soda.
If you want to drink something sparkly you are better off with carbonated water.
