If your daily routine involves an energizing cup of coffee, you may want to rethink what you choose to put in it.
Drinking coffee has been linked to a lower risk of death. The catch is, mortality risk based on coffee consumption changes with the amount of sweeteners and saturated fat added, according to a study from the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University.
“Coffee is among the most-consumed beverages in the world, and with nearly half of American adults reporting drinking at least one cup per day, it’s important for us to know what it might mean for health,” Fang Fang Zhang, senior author of the study, said.
“The health benefits of coffee might be attributable to its bioactive compounds, but our results suggest that the addition of sugar and saturated fat may reduce the mortality benefits.”
The study found that drinking black coffee and coffee with low levels of added sugar and saturated fat were associated with a 14% lower risk of all-cause mortality as compared to no coffee consumption.
But for coffee with high amounts of added sugar and saturated fat, results varied.
The study analyzed data from the National Health and Nutrition Examination Survey from 1999 to 2018 and National Death Index Mortality Data.
Among the studied 46,332 U.S. adults aged 20 or over, 7,074 people have died. Those deaths were then cross-referenced against coffee consumption, according to reports.
The researchers found that people who drink coffee showed a lower risk of all-cause mortality, but when more than a little sugar and saturated fat was added, the risks were heightened.
While limited in scope, the study suggests that drinking caffeinated coffee could help you live longer, while decaffeinated coffee drinkers saw no difference in mortality rates. And taking sugar, milk and cream in your coffee could increase mortality.
“Few studies have examined how coffee additives could impact the link between coffee consumption and mortality risk, and our study is among the first to quantify how much sweetener and saturated fat are being added,” researcher Bingjie Zhou said.
“Our results align with the Dietary Guidelines for Americans which recommend limiting added sugar and saturated fat.”
