Effects of the Daily Consumption of Stevia on Glucose Homeostasis, Body Weight, and Energy Intake: A Randomised Open-Label 12-Week Trial in Healthy Adults.

ABSTRACT: Stevia is a non-nutritive sweetener, providing sweet taste with no calories. This randomised, controlled, open-label 2-parallel arm trial examined the effects of daily stevia consumption on glycaemia in healthy adults. Secondary endpoints included body weight (BW) and energy intake (EI). Healthy participants (n = 28; aged 25 ± 5y, body mass index 21.2 ± 1.7 kg/m2) were randomised into either the stevia group (n = 14)-required to consume a stevia extract daily-or to the control group (n = 14). At weeks 0 and 12, the glucose and insulin responses to an oral glucose tolerance test were measured; BW and EI were assessed at weeks 0, 6, and 12. There was no significant difference in the glucose or insulin responses. There was a significant main effect of group on BW change (F(1,26) = 5.56, p = 0.026), as the stevia group maintained their weight as opposed to the control group (mean weight change at week 12: -0.22 kg, 95%CI [-0.96, 0.51] stevia group, +0.89 kg, 95%CI [0.16, 1.63] control group). The energy intake was significantly decreased between week 0 and 12 in the stevia group (p = 0.003), however no change was found in the control group (p = 0.973). Although not placebo-controlled, these results suggest that daily stevia consumption does not affect glycaemia in healthy individuals, but could aid in weight maintenance and the moderation of EI.

Project description:Abstract Objectives Stevia is a non-nutritive sweetener providing sweet taste with zero calories that could constitute an effective strategy toward sugar reduction. This study tested the effects of daily consumption of stevia drops on glycemia, body weight (BW) and energy intake in healthy normal weight adults, non-habitual consumers of non-nutritive sweeteners. Methods Twenty eight healthy participants were randomly assigned to the stevia group (n = 14, mean age: 25 ± 5.5 y, mean body mass index: 22 ± 1.8 kg/m2) and were required to consume 5 drops of a commercially available stevia extract twice daily along with their habitual drinks, or to the control group (n = 14, 25 ± 4.2 y, 21 ± 1.5 kg/m2) and were instructed not to change anything in their diet for 12 weeks. Both groups were encouraged to maintain their usual diet and physical activity habits. At baseline and week 12, glucose response to an oral glucose tolerance test (OGTT) was measured; BW and energy intake were assessed at baseline, week 6 and week 12. Results There was no significant difference in glucose response to the OGTT over the 12 weeks in any study group. However, there was a significant main effect of participant group on BW change over the 12 weeks (F(1, 26) = 5.56, P = 0.026), showing that stevia consumption prevented weight gain (ΔWeight at week 12 = −0.22 ± 0.32 kg for stevia, +0.89 ± 0.39 kg for the control group). Energy intake was significantly decreased between baseline and week 12 in the stevia group (ΔEnergy at week 12 = −344 ± 80.6 kcal, P = 0.003), however no change in energy intake was found in the control group (ΔEnergy = +13.6 ± 125 kcal, P = 0.973). Conclusions These results suggest that daily consumption of stevia in real-life doses does not affect glycemia in healthy normal-weight individuals, but could aid toward weight maintenance and moderation of energy intake. More research is warranted to explore these promising findings further in individuals with overweight/obesity and/or individuals with impaired glucose tolerance (i.e., pre-diabetes/diabetes).

Project description:BACKGROUND: Feed efficiency is one of the major components determining costs of animal production. Residual feed intake (RFI) is defined as the difference between the observed and the expected feed intake given a certain production. Residual feed intake 1 (RFI1) was calculated based on regression of individual daily feed intake (DFI) on initial test weight and average daily gain. Residual feed intake 2 (RFI2) was as RFI1 except it was also regressed with respect to backfat (BF). It has been shown to be a sensitive and accurate measure for feed efficiency in livestock but knowledge of the genomic regions and mechanisms affecting RFI in pigs is lacking. The study aimed to identify genetic markers and candidate genes for RFI and its component traits as well as pathways associated with RFI in Danish Duroc boars by genome-wide associations and systems genetic analyses. RESULTS: Phenotypic and genotypic records (using the Illumina Porcine SNP60 BeadChip) were available on 1,272 boars. Fifteen and 12 loci were significantly associated (p < 1.52 × 10-6) with RFI1 and RFI2, respectively. Among them, 10 SNPs were significantly associated with both RFI1 and RFI2 implying the existence of common mechanisms controlling the two RFI measures. Significant QTL regions for component traits of RFI (DFI and BF) were detected on pig chromosome (SSC) 1 (for DFI) and 2 for (BF). The SNPs within MAP3K5 and PEX7 on SSC 1, ENSSSCG00000022338 on SSC 9, and DSCAM on SSC 13 might be interesting markers for both RFI measures. Functional annotation of genes in 0.5 Mb size flanking significant SNPs indicated regulation of protein and lipid metabolic process, gap junction, inositol phosphate metabolism and insulin signaling pathway are significant biological processes and pathways for RFI, respectively. CONCLUSIONS: The study detected novel genetic variants and QTLs on SSC 1, 8, 9, 13 and 18 for RFI and indicated significant biological processes and metabolic pathways involved in RFI. The study also detected novel QTLs for component traits of RFI. These results improve our knowledge of the genetic architecture and potential biological pathways underlying RFI; which would be useful for further investigations of key candidate genes for RFI and for development of biomarkers.
