In a recent systematic review, we investigated the medium- and long-term effects of
non-nutritive sweeteners (NNS) in people with diabetes mellitus. We included randomised
controlled trials (RCTs) with a duration of four weeks or more comparing any type
of NNS with usual diet, no intervention, placebo, water, a different NNS, or a nutritive
sweetener in individuals with type 1 or type 2 diabetes.
