Adults who consumed moderate quantities of unsweetened or sugar-sweetened coffee (1.5 to 3.5 cups per day) were less likely to die over a seven-year follow-up period than those who did not drink coffee. Artificial sweeteners may have influenced the outcomes. A report on the results appears in the Annals of Internal Medicine journal.
Coffee drinking has been linked to a decreased mortality risk in previous research, however these studies did not differentiate between unsweetened coffee and coffee sweetened with sugar or artificial sweeteners. According to a study conducted by scientists from the Southern Medical University in Guangzhou using data from the U.K. Biobank health – related behavior survey, sugar-sweetened coffee intake was linked to all-cause death but intake of artificially sweetened coffee was not.
To find out how much coffee people drink, researchers polled more than 171,000 people in the United Kingdom with no history of heart disease or cancer.
Participants who drank any quantity of unsweetened coffee had a 16-21% lower mortality rate than those who didn’t drink coffee over the 7-year follow-up period, according to the investigators.
Participants who consumed 1.5 to 3.5 sugar-sweetened cups of coffee daily had a 29 to 31 percent lower mortality rate than those who didn’t. Only around 1 teaspoon of sugar was added to each cup of sugar-sweetened coffee consumed by adults, researchers found. Participants who drank their coffee with artificial sweeteners had mixed results. Even if coffee’s health advantages may be measurable, the publishers of Annals of Internal Medicine point out in their editorials that other extraneous factors such as socioeconomic position and dietary habits may have an effect on the results. The participants’ information is at least 10 years old and was gathered in a nation where tea is a popular drink, according to the authors.
Since many coffee lovers may substitute their cup of joe for other beverages, it’s difficult to draw accurate comparisons between coffee drinkers and those who don’t partake in the sugary beverage industry. Clinicians may inform their patients, relying on this research, that most coffee consumers don’t need to cut out the drink altogether, but they should watch out for speciality coffees with higher calorie counts.
