Hormonal responses to non-nutritive sweeteners in water and diet soda
Background Non-nutritive sweeteners ( NNS ) , especially in form of diet soda , have been linked to metabolic derangements ( e.g. obesity and diabetes ) in epidemiologic studies . We aim ed to test acute metabolic effects of NNS in isolation ( water or seltzer ) and in diet sodas . Methods We conducted a four-period , cross-over study at the National Institutes of Health Clinical Center ( Bethesda , Maryl and ) . Thirty healthy adults consumed 355 mL water with 0 mg , 68 mg , 170 mg , and 250 mg sucralose , and 31 individuals consumed 355 mL caffeine-free Diet Rite Cola ™ , Diet Mountain Dew ™ ( 18 mg sucralose , 18 mg acesulfame-potassium , 57 mg aspartame ) , and seltzer water with NNS ( 68 mg sucralose and 41 mg acesulfame-potassium , equivalent to Diet Rite Cola ™ ) in r and omized order , prior to oral glucose tolerance tests . Blood sample s were collected serially for 130 min . Measures included GLP-1 , GIP , glucose , insulin , C-peptide , glucose absorption , gastric emptying , and subjective hunger and satiety ratings . Results Diet sodas  augmented active GLP-1 ( Diet Rite Cola ™ vs. seltzer water , AUC , p = 0.039 ; Diet Mountain Dew ™ vs. seltzer water , AUC , p = 0.07 ) , but gastric emptying and satiety were unaffected . Insulin concentrations were nominally higher following all NNS conditions without altering glycemia . Sucralose alone ( at any concentration ) did not affect metabolic outcomes . Conclusions Diet sodas but not NNS in water augmented GLP-1 responses to oral glucose . Whether the trends toward higher insulin concentrations after NNS are of clinical importance remains to be determined . Our findings emphasize the need to test metabolic effects of NNS after chronic consumption . Trial registration The data for this manuscript were gathered from clinical trial # NCT01200940
