Study: Drinking Soda Pop Daily can Shorten Your Life

Researchers at the University of California — San Francisco found study participants who drank pop daily had shorter telomeres — the protective units of DNA that cap the ends of chromosomes in cells — in white blood cells. Short telomeres have been associated with chronic aging diseases such as heart disease, diabetes and some forms of cancer

The article is quite brief – here’s a link to the study.  They performed a cross-sectional study across ~5,000 adults, looking at the effect of sugar-sweetened beverages (SSB), non-carbonated SSBs, diet soda, and fruit juices. They adjusted for socio-demographic and health-related characteristics, and found that SSBs are correlated with shorter telomeres; fruit juice with longer telomeres, and no difference for diet sodas and non-carbonated SSBs.  They might have been looking at a lot of different nutrition factors and only reported those which appeared significant after the experiment (obligatory XKCD)

TLDR: Soda Pop Damages Your Cells’ Telomeres

Something else to keep in mind is that consuming crbon dioxide (CO2) rapidly, as happens when drinking carbonated beverages, leads to stomach expansion. The stomach is capable of increasing in size to accommodate a large meal but if the practice is habitual the stomach will actually grow in size permanently. There is a nerve where the esophagus meets the stomach that triggers when the stomach is full. When triggered it tells the brain to stop eating (you are no longer hungry). Studies have linked an enlarged stomach to overeating/obesity because of not feeling sated. While it may not have a direct link to obesity, there is evidence it may be indirectly linked.
