HOUSTON, Tx. - Doctors at the University of California at San Francisco studied sugary-sweet sodas for five years and determined that, aside from being high in calories, the fizzy fructose-laden fountain drinks actually weakened the ability of people's cells to regenerate and caused them to age faster.
"When they looked at the cellular level -- which I think was a great and unique part of this study," Dr. John Higgins, with UT Health and the Harris Health System in Houston said, "they found there were changes in the dna of the cells caused by these sodas that have sugar in them."
So, ready to trade your trusty tonic for a tumbler of H20?
"Could be true," Houstonian Jenna Pelkemeyer says, "I mean, I'm 40 but, you know, I don't feel like I look 40. But I'm sure if I keep drinking too many it will happen, that I'll look older."
"I'm actually a physician so I definitely don't condone people drinking those things," Thiago Halmer says, "and I myself need to lead by example."
The good news is that diet sodas showed no impact on cell regeneration throughout the study. Meaning that if you have to have sugary-sweet seltzer, diet just may be the way to go.
