The study from the American Heart Association - based on data from 2010 - links the death of 180,000 people worldwide, and 25,000 Americans to an over-consumption of sweetened drinks.
It claims that the drinks pack on extra pounds, which up the risk of death from other diseases such as diabetes, cardiovascular disease and cancer.
The study was funded in part by the National Institute of Diabetes and Digestive and Kidney Diseases.
Of the countries in the study, Mexico had the highest number of deaths, with the US coming in at number three.
Japan had the lowest number of deaths linked to the drinks.
The American Beverage Association says the report is "more about sensationalism than science.”
