Non-alcoholic beverage and caffeine consumption and mortality: the Leisure World Cohort Study.
To examine the effects of non-alcoholic beverage and caffeine consumption on all-cause mortality in older adults. ⋯ Moderate caffeine consumption appeared beneficial in reducing risk of death. Attenuation in the observed associations between mortality and intake of tea and milk with adjustment for potential confounders suggests that such consumption identifies those with other mortality-associated lifestyle and health risks. The increased death risk with consumption of artificially sweetened, but not sugar-sweetened, soft drinks suggests an effect of the sweetener rather than other components of the soft drinks, although residual confounding remains a possibility.
