Changes in glucose tolerance and insulin sensitivity following 2 weeks of daily cinnamon ingestion in healthy humans

Solomon, Thomas P. J., Blannin, Andrew K.·2009·European Journal of Applied Physiology

Abstract

Cinnamon can improve fasting glucose in humans yet data on insulin sensitivity are limited and controversial. Eight male volunteers (aged 25 +/- 1 years, body mass 76.5 +/- 3.0 kg, BMI 24.0 +/- 0.7 kg m(-2); mean +/- SEM) underwent two 14-day interventions involving cinnamon or placebo supplementation (3 g day(-1)). Placebo supplementation was continued for 5 days following this 14 day period. Oral glucose tolerance tests (OGTT) were performed on days 0, 1, 14, 16, 18, and 20. Cinnamon ingestion reduced the glucose response to OGTT on day 1 (-13.1 +/- 6.3% vs. day 0; P < 0.05) and day 14 (-5.5 +/- 8.1% vs. day 0; P = 0.09). Cinnamon ingestion also reduced insulin responses to OGTT on day 14 (-27.1 +/- 6.2% vs. day 0; P < 0.05), as well as improving insulin sensitivity on day 14 (vs. day 0; P < 0.05). These effects were lost following cessation of cinnamon feeding. Cinnamon may improve glycaemic control and insulin sensitivity, but the effects are quickly reversed.

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.
