The Academy of Nutrition and Dietetics' current position on nonnutritive sweeteners is that they may help limit inatke of energy in an effort to manage weight or blood glucose. The consumption of artificial sweeteners, including aspartame, sucralose, and stevia, however, has been associated with both weight gain and incident obesity.
Existing evidence, from both randomized controlled trials and observational studies, is conflicting.
The objective of the meta-analysis summarized in the short slide show above was to determine whether "routine consumption of nonnutritive sweeteners by adults and adolescents [is] associated with adverse long-term cardiometabolic effects in RCTs and prospective cohort studies."
