Change of Alpha-Amylase Activity in Saliva in Response to Blood Glucose After A High Carbohydrate Ingestion

Salivary α-amylase activity (SAA) may be correlated with blood glucose levels. However, change of SAA in response to blood glucose after carbohydrate diet remains unknown. In 17 healthy young adults, SAA was inversely correlated with blood glucose levels (r = −0.57, P = 0.02) at 1 h after a high carbohydrate ingestion, corresponding to a nadir in salivary α-amylase activity and a peak in blood glucose, suggesting a close link between these factors.
