Symptoms: Metabolic Syndrome Is Tied to Diet Soda
By NICHOLAS BAKALAR
Published: February 5, 2008
Obviously, correlation isn't causation, but one more reason to be careful about this stuff (see the other 2 reasons on the home page if that isn't enough).Researchers have found a correlation between drinking diet soda and metabolic syndrome â€” the collection of risk factors for cardiovascular disease and diabetes that include abdominal obesity, high cholesterol and blood glucose levels, and elevated blood pressure.
â€œThis is interesting,â€ said Lyn M. Steffen, an associate professor of epidemiology at the University of Minnesota and a co-author of the paper, which was posted online in the journal Circulation on Jan. 22. â€œWhy is it happening? Is it some kind of chemical in the diet soda, or something about the behavior of diet soda drinkers?â€
