Abstract

Aims: Resveratrol, a natural polyphenolic compound produced by various plants (e.g. red grapes) and found in red wine, has glucose‐lowering effects in humans and rodent models of obesity and/or diabetes. The mechanisms behind these effects have been suggested to include resveratrol‐induced secretion of the gut incretin hormone glucagon‐like peptide‐1. We investigated postprandial incretin hormone and glucagon responses in obese human subjects before and after 30 days of resveratrol supplementation. Methods: Postprandial plasma responses of the incretin hormones glucagon‐like peptide‐1 and glucose‐dependent insulinotropic polypeptide and glucagon were evaluated in 10 obese men [subjects characteristics (mean ± standard error of the mean): age 52 ± 2 years; BMI 32 ± 1 kg/m 2, fasting plasma glucose 5.5 ± 0.1 mmol/l] who had been given a dietary supplement of resveratrol (Resvida® 150 mg/day) or placebo for 30 days in a randomized, double‐blind, crossover design with a 4‐week washout period. At the end of each intervention period a standardized meal test (without co‐administration of resveratrol) was performed. Results: Resveratrol supplementation had no impact on fasting plasma concentrations or postprandial plasma responses (area under curve values) of glucose‐dependent insulinotropic polypeptide (11.2 ± 2.1 vs. 11.8 ± 2.2 pmol/l, P = 0.87; 17.0 ± 2.2 vs. 14.8 ± 1.6 min × nmol/l, P = 0.20) or glucagon‐like peptide‐1 (15.4 ± 1.0 vs. 15.2 ± 0.9 pmol/l, P = 0.84; 5.6 ± 0.4 vs. 5.7 ± 0.3 min × nmol/l, P = 0.73). Resveratrol supplementation significantly suppressed postprandial glucagon responses (4.4 ± 0.4 vs. 3.9 ± 0.4 min × nmol/l, P = 0.01) without affecting fasting glucagon levels (15.2 ± 2.2 vs. 14.5 ± 1.5 pmol/l, P = 0.56). Conclusions: Our data suggest that 30 days of resveratrol supplementation does not affect fasting or postprandial incretin hormone plasma levels in obese humans, but suppresses postprandial glucagon responses.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
