Drinking Soda Each Day Has Accelerating Effect On Cellular Aging

While consuming sugary soft drinks is often associated with a higher risk of obesity, metabolic syndrome, diabetes, cardiovascular death, and certain types of cancer, new research suggests that it can also shorten our lifespan.  A recent study conducted at the University of California, San Francisco (UCSF) has revealed that drinking soda frequently can shorten the length of telomeres within white blood cells, which can be used as a predictor for human lifespan.

“Regular consumption of sugar-sweetened sodas might influence disease development, not only by straining the body’s metabolic control of sugars, but also through accelerated cellular aging of tissues.”  

Researchers determined that drinking 20 ounces of soda a day was linked to 4.6 years of additional biological aging. This conclusion was made by assessing the way telomere length shortens with chronological age. The effect drinking soda had on telomere shortening was comparable to smoking or, in the opposite, anti-aging direction, regular exercise. Previous studies have also associated telomere shortening with chronic diseases of aging, such as heart disease, diabetes, and certain types of cancer.

“This finding held regardless of age, race, income, and education level. Telomere shortening starts long before disease onset.  Further, although we only studied adults here, it is possible that soda consumption is associated with telomere shortening in children, as well.” 

“It is critical to understand both dietary factors that may shorten telomeres, as well as dietary factors that may lengthen telomeres.  Here it appeared that the only beverage consumption that had a measurable negative association with telomere length was consumption of sugared soda.”
