Soda might age you as much as smoking.
Researchers studied white blood cell telomeres (the caps at the end of chromosomes in every cell). Shorter telomeres are associated with cardiovascular disease, diabetes, cancer, stress and a shorter lifespan. People who drank more sugary soda tended to have shorter telomeres. One 8-oz serving daily was found to be equal to 1.9 years of additional aging; a 20-oz serving was equal to 4.6 years of aging, equivalent to the impact of smoking! Non-carbonated sodas and sweetened fruit juices did not demonstrate the impact.
PositiveTip: Sugary, soda beverages contribute no nutritional or health advantages.
