Effects of short-term cinnamon ingestion on in vivo glucose tolerance.
AIMS Various spices display insulin-potentiating activity in vitro , and in particular , cinnamon spice and its phenolic extracts have been shown to exhibit these capabilities . In vivo study shows that cinnamon may have beneficial effects on glucose homeostasis ; therefore the aim of this study was to further investigate this phenomenon in humans . METHODS Seven lean healthy male volunteers , aged 26 + /- 1 years , body mass index 24.5 + /- 0.3 kg/m(2 ) ( mean + /- s.e.m . ) , underwent three oral glucose tolerance tests ( OGTT ) supplemented with either a 5 g placebo ( OGTT(control ) ) , 5 g of cinnamon ( OGTT(cin ) ) , or 5 g of cinnamon taken 12 h before ( OGTT(cin12hpre ) ) in a r and omized-crossover design . RESULTS Cinnamon ingestion reduced total plasma glucose responses ( AUC ) to oral glucose ingestion [ -13 % and -10 % for OGTT(cin ) ( p < 0.05 ) and OGTT(cin12hpre ) ( p < 0.05 ) , respectively ] , as well as improving insulin sensitivity as assessed by insulin sensitivity index measures based on Matsuda 's model in both OGTT(cin ) ( p < 0.05 ) and OGTT(cin12hpre ) ( p < 0.05 ) trials compared with OGTT(control ) . CONCLUSIONS These data illustrate that cinnamon spice supplementation may be important to in vivo glycaemic control and insulin sensitivity in humans , and not only are its effects immediate , they also appear to be sustained for 12
