BACKGROUND & AIMS: Lactose-hydrolyzed milk is widely used to address lactose intolerance. However, its monosaccharide content may rapidly increase postprandial blood glucose levels and heighten glycemic variability. We aimed to explore the effects of mulberry leaf and corn silk extracts (medicinal and edible homologous materials) and their supplementation in lactose-hydrolyzed milk on postprandial glycemic control in adults with type 2 diabetes.
METHODS: Eligible participants in this crossover trial were randomized to four interventions, separated by a 7 d washout. Intervention foods were whole-grain bread (50 g carbohydrates) together with water, mulberry leaf and corn silk extracts (MCE), lactose-hydrolyzed milk (LHM), or lactose-hydrolyzed milk supplemented with mulberry leaf and corn silk extracts (LHM-MCE). Continuous glucose monitoring systems were used to collect fasting and postprandial interstitial glucose over 2 h after interventions and to calculate the incremental area under the curve (iAUC). Paired Wilcoxon signed-rank test was used to compare the difference in iAUC, 1-h postprandial glycemic (1h PG), 2h PG, maximum glycemic, and maximum glucose excursion from baseline across interventions.
RESULTS: Twenty-eight adults with type 2 diabetes (55 ± 10 years old, fasting blood glucose: 6.93 ± 1.22 mmol/L) completed the trial. MCE was associated with lower levels of maximum glycemic (median of difference [interquartile range]: (-0.9 [-1.9, 0.4], P = 0.025) and maximum glucose excursion from baseline (-0.9 [-1.5, -0.03], P = 0.005) compared to water. LHM-MCE was associated with lower levels of 1h PG (-0.7 [-1.9, 0.4], P = 0.04), maximum glycemic (-0.9 [-2.2, 0.4], P = 0.014), and maximum glucose excursion from baseline (-1.0 [-2.3, -0.4], P = 0.003) compared to LHM.
CONCLUSIONS: Mulberry leaf and corn silk extracts may benefit postprandial glycemic control and their incorporation into lactose-hydrolyzed milk could be a promising dietary intervention for patients with type 2 diabetes.
