Consequences of both sweetened and unsweetened coffee consumption - Video

Several studies have observed the health effects of coffee and they have also found that coffee consumption is associated with a lower risk of death but did not distinguish between unsweetened coffee and coffee consumed with sugar or artificial sweeteners.

A cohort study published in in Annals of Internal Medicine has found that compared to non-coffee drinkers, adults who drank moderate amounts (1.5 to 3.5 cups per day) of unsweetened coffee or coffee sweetened with sugar were less likely to die during a 7-year follow up period

More than 171,000 participants without known heart disease or cancer were asked several dietary and health behavior questions to determine coffee consumption habits. The authors found that during the 7-year follow up period, participants who drank any amount of unsweetened coffee were 16 to 21 percent less likely to die than participants who did not drink coffee.

They also found that participants who drank 1.5 to 3.5 daily cups of coffee sweetened with sugar were 29 to 31 percent less likely to die than participants who did not drink coffee.

Coffee has qualities that could make health benefits possible. The authors caution that the average amount of daily sugar per cup of coffee recorded in this analysis is much lower than specialty drinks at popular coffee chain restaurants, and many coffee consumers may drink it in place of other beverages that make comparisons to non-drinkers more difficult.
