Introduction:
steviosides (Steviol glycoside and Rebaudioside A) are non-caloric, natural sweeteners from the plant Stevia rebaudiana with potential metabolic benefits beyond its sweetness. We aimed to assess low-dose effect of Rebaudioside A on glucose metabolism in type 2 diabetic (T2DM) patients.
Methods:
we carried out an experimental study at the National Obesity Centre of the
Yaoundé Central Hospital on T2DM patients with satisfactory metabolic control.
They underwent in a fasting state, 48 hours apart, in a random order a standard
mixed meal tolerance test containing 54g of carbohydrates, 20g of lipids and
26g of proteins for a total of 410 kcal,with or without addition of 240 mg of
Rebaudioside A. Glucose and C peptide concentrations were measured at baseline
and at 30, 60, 90 and 120 min after ingestion of the test meal.
Results:
sixteen patients (10 males and 6 females) aged 59 [50.5-60.5] years, with
3.5 [3.6-5.0] years duration of diabetes and HbA1c of 42.0 [37.5-49.3] mmol/molparticipated
in the study. The glycemic response to the mixed meal test without Stevia
and with Stevia was [5,6 (5,2-6,6) mmol/l vs 5,5(5,2-6,5) mmol/l; p = 0,8]
at T0,
[6,1(5,6-6,8) mmol/l vs 5,7(5,3-6,5) mmol/l; p = 0,01]. The C-peptide variations
during the mixed meal test without Stevia and with Stevia was 0,03 [0,03-0,06]nmol/l
vs 0,06 [0,05-0,1]nmol/l at T0 (p = 0.02), 0,05 [0,04-0,07]nmol/l vs 0,08
[0,06-0,1]nmol/l, (p = 0.21) at T30 and 0,06 [0,04-0,07]nmol/l vs 0,07
[0,06-0,09]nmol/l, (p = 0.20) at T120 with a non-significant decrease of
the AUC by 32% (6,3 [5,7-7,3]
nmol/l/120 min vs 9,3 [7,1-12,1] nmol/l/120 min, p = 0.19).
Conclusion:
low-dose stevioside reduced blood glucose response to a mixed meal tolerance test in well controlled T2DM patients, with a non-significant increase in insulin secretory response and may prove metabolic benefits in addition to its sweetening effect.
