摘要
The aim of this study was to examine the inhibitory effect of acute oral chlorogenic acid (CGA) ingestion on increases in blood glucose levels following glucose tolerance testing. Ten healthy male adults (age: 25.9 ± 5.4 years) participated in the study. Blood samples were collected from the antecubital vein of subjects following overnight fasting. After a 120-min rest, they were administered 75 g glucose and chlorogenic acid or placebo. The amount of chlorogenic acid administered (in the form of capsules) to the subjects was 0.1g per body mass. In addition, only capsules were ingested in placebo ingestion conditions. Blood samples were collected 4 times during the 120-min rest period at intervals of 30 min. Serum insulin and plasma glucose levels were analyzed. Serum insulin levels increased significantly at 30 min after glucose ingestion, and fixed until 120 min in both conditions. Plasma glucose level increased significantly at 30 min after glucose ingestion, followed by a slow decrease. In addition, no significant difference was found between the conditions in each parameter. In conclusion, acute oral chlorogenic acid ingestion may not inhibition blood glucose increase following glucose tolerance.
