Glycaemic control, in particular at postprandial period, has a key role in prevention of different diseases, including diabetes and cardiovascular events. Previous studies suggest that postprandial high blood glucose levels (BGL) can lead to an oxidative stress status, which is associated with metabolic alterations. Cinnamon powder has demonstrated a beneficial effect on postprandial glucose homeostasis in animals and human models. The purpose of this study is to investigate the effect of cinnamon tea (C. burmannii) on postprandial capillary blood glucose level on nondiabetic adults. Participants were given oral glucose tolerance test either with or without cinnamon tea in a randomized clinical trial. The data revealed that cinnamon tea administration slightly decreased postprandial BGL. Cinnamon tea ingestion also results in a significantly lower postprandial maximum glucose concentration and variation of maximum glucose concentration (p < 0.05). Chemical analysis showed that cinnamon tea has a high antioxidant capacity, which may be due to its polyphenol content. The present study provides evidence that cinnamon tea, obtained from C. burmannii, could be beneficial for controlling glucose metabolism in nondiabetic adults during postprandial period.
血糖控制，尤其是在餐后阶段，对预防包括糖尿病和心血管事件在内的各种疾病起着关键作用。先前的研究表明，餐后高血糖水平（BGL）可导致氧化应激状态，这与代谢改变有关。肉桂粉已在动物和人体模型中显示出对餐后葡萄糖稳态的有益作用。本研究的目的是调查肉桂茶（阴香）对非糖尿病成年人餐后毛细血管血糖水平的影响。在一项随机临床试验中，参与者接受了口服葡萄糖耐量试验，试验中有的服用肉桂茶，有的未服用。数据显示，饮用肉桂茶会使餐后BGL略有下降。摄入肉桂茶还会使餐后最大血糖浓度以及最大血糖浓度变化显著降低（p<0.05）。化学分析表明，肉桂茶具有较高的抗氧化能力，这可能归因于其多酚含量。本研究提供了证据，表明从阴香中获取的肉桂茶可能有助于在餐后阶段控制非糖尿病成年人的葡萄糖代谢。
