High Blood Glucose After Starch Loading in Young Women With Small Increase in Salivary Amylase: Another Crucial Role of Postprandial Salivary Amylase
Bibliographic record
Abstract
Background: Salivary α-amylase plays a crucial role in the glucose metabolism. However, postprandial salivary α-amylase activity (SAA) and its relationship with blood glucose (BG) are poorly understood. Therefore, we investigated SAA and BG after starch loading in healthy young women. Methods: In 60 healthy non-obese young women, we investigated SAA, BG, and blood 3-hydroxybutyrate (3HB) after the consumption of 150 g rice (starch 48.8 g). Participants were classified into two groups based on the changes (Δ) in SAA from baseline at 60 min: small- and large-increase in ΔSAA groups (SI-ΔSAA and LI-ΔSAA). Results: BG levels were significantly higher at 60, 90, and 120 min in participants with SI-ΔSAA (n = 31) than LI-ΔSAA (n = 29). Baseline 3HB concentration was also higher in participants with SI-ΔSAA. ΔSAA at 60 min was most closely and inversely correlated with BG and ΔBG at 90 min (r = -0.53 and -0.50, both P < 0.0001). Generalized linear model analysis also indicated that ΔSAA at 60 min was the most predictive of ΔBG at 90 min. Conclusions: Higher levels of BG and ΔBG were observed after starch loading in healthy young women with smaller increase in salivary amylase, suggesting another crucial role of postprandial salivary amylase for the postprandial glucose metabolism.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
