Sugar-free and ‘diet’ drinks are often seen as the healthier option, however, researchers from the Imperial College London argue that they are no more helpful for maintaining a healthy weight that their full-sugar counterparts. The research was conducted by academics from Imperial College London, University of Sao Paulo and Federal University of Pelotas, Brazil. They provided a commentary on current research and policy into sweetened drinks. They found that not only were they sugar-free drinks no better from weight loss, but that they may also be detrimental to the environment.
