背景:富含生物碱和多酚的白桑叶和苹果皮提取物已被证明具有潜在的降糖作用,有利于控制餐后血糖水平。这项研究旨在确定在摄入富含碳水化合物的膳食或蔗糖饮料后,苹果皮和桑叶提取物(GLUBLOCTM)的组合对健康成年人餐后血糖和胰岛素降低作用的影响。
方法:本研究设计为随机,交叉,单盲临床试验。在116名健康参与者中,85名受试者(年龄18-60岁)完成第1天和第5天的交叉研究。在第1天,在摄入富含碳水化合物的膳食(300g番茄米)或蔗糖饮料(75g蔗糖溶解在300mL水中)之前10分钟,向受试者补充安慰剂或GLUBLOCTM片剂。在第5天,交叉治疗,并遵循相同的饮食。在第1天和第5天(基线0,餐后30、60、90和120分钟)测量餐后血糖和胰岛素水平。iAUC的差异,Cmax,在安慰剂组和GLUBLOCTM治疗组之间测定Tmax.
结果:总iAUC(0-120分钟)的显着变化,Cmax,补充GLUBLOCTM后注意到餐后血糖和胰岛素水平的Tmax。血糖水平的iAUC降低百分比为49.78%(iAUC0-60min)和43.36%(iAUC0-120min),分别,在蔗糖饮料摄入研究中与安慰剂相比。同样,在富含碳水化合物的膳食摄入研究中,与安慰剂相比,有41.13%(iAUC0-60min)和20.26%(iAUC0-120min)的降糖效果.
结论:餐前补充GLUBLOCTM显著降低了健康个体在摄入富含碳水化合物的膳食或蔗糖饮料超过120分钟后血糖和胰岛素水平的餐后激增。这项研究证明GLUBLOCTM可以控制稳定的餐后血糖水平。
BACKGROUND: Alkaloid- and polyphenol-rich white mulberry leaf and apple peel extracts have been shown to have potential glucose-lowering effects, benefitting the control of postprandial blood glucose levels. This
study aimed to determine the effect of the combination of Malus domestica peel and Morus alba leaf extracts (GLUBLOCTM) on postprandial blood glucose and insulin-lowering effects in healthy adults after a carbohydrate-rich meal or sucrose drink intake.
METHODS: This
study was designed as a randomized, crossover, single-blinded clinical
trial. Out of 116 healthy participants, 85 subjects (aged 18-60 years) completed the day 1 and 5 crossover
study. On day 1, subjects were supplemented with a placebo or GLUBLOCTM tablet 10 min before the carbohydrate-rich meal (300 g of tomato rice) or sucrose drink intake (75 g of sucrose dissolved in 300 mL water). On day 5, the treatments were crossed over, and the same diet was followed. Postprandial blood glucose and insulin levels were measured on days 1 and 5 (baseline 0, post-meal 30, 60, 90, and 120 min). Differences in iAUC, Cmax, and Tmax were determined between the placebo and GLUBLOCTM-treated cohorts.
RESULTS: Significant changes in total iAUC (0-120 min), Cmax, and Tmax of postprandial blood glucose and insulin levels were noticed upon GLUBLOCTM supplementation. The percentage reduction in the iAUC of blood glucose levels was 49.78% (iAUC0-60min) and 43.36% (iAUC0-120min), respectively, compared with the placebo in the sucrose drink intake study. Similarly, there was a 41.13% (iAUC0-60min) and 20.26% (iAUC0-120min) glucose-lowering effect compared with the placebo in the carbohydrate-rich meal intake
study.
CONCLUSIONS: Premeal supplementation with GLUBLOCTM significantly reduced the postprandial surge in blood glucose and insulin levels after a carbohydrate-rich meal or sucrose drink intake over 120 min in healthy individuals. This
study proves that GLUBLOCTM can manage steady postprandial blood glucose levels.
