Research evidence suggests that vinegar may effectively reduce postprandial glucose in both healthy adults and those with type 2 diabetes. There is heightened consumer interest in commercially available vinegar tablets; however, it is not known whether these products lower postprandial glycemia to the same extent as liquid vinegar. This crossover trial examined the impact of liquid vinegar versus commercial vinegar tablet ingestion at the start of a meal on the 60-minute glucose excursion postmeal in healthy adults.
Twelve young men and women (22.6 ± 0.6 y; 21.2 ± 1.2 kg/m) completed this 4-arm Latin square crossover trial. Testing was separated by one week and consisted of a test meal (64 g carbohydrate) consumed immediately following one of the four oral treatments: CON, 60 g water (control treatment); VIN, 25 g liquid vinegar (5% acidity; 1.25 g acetic acid) diluted with 35 g water; PILL, four vinegar tablets (1.50 g acetic acid) swallowed whole with 60 g water; and PILL-c, four crushed vinegar tablets dissolved in 60 g water. Capillary blood glucose was tested in the fasted state and at 30 and 60 minutes postmeal.
The 60-minute glucose excursion varied significantly by treatment (iAUC: 4.9 ± 0.6, 3.4 ± 0.4, 4.9 ± 0.6, and 4.1 ± 0.5 mmol˖h/l for CON, VIN, PILL, and PILL-c, respectively; (3, 33) = 3.037, = 0.043; repeated measures ANOVA). Post hoc analysis revealed a 31% reduction in the glucose postmeal excursion for VIN in comparison to CON and PILL ( = 0.040 and = 0.049, respectively).
These data suggest that commercial vinegar tablets taken whole at mealtime are not as effective as liquid vinegar for reducing the postmeal glucose excursion in young, healthy adults.
研究证据表明，醋可能有效降低健康成年人及2型糖尿病患者的餐后血糖。消费者对市售醋片的兴趣日益浓厚；然而，尚不清楚这些产品降低餐后血糖的程度是否与液态醋相同。这项交叉试验研究了在健康成年人用餐开始时摄入液态醋与市售醋片对餐后60分钟血糖波动的影响。
12名年轻男性和女性（22.6±0.6岁；21.2±1.2kg/m）完成了这项4臂拉丁方交叉试验。测试间隔一周，包括在四种口服处理之一后立即食用的测试餐（64g碳水化合物）：CON，60g水（对照处理）；VIN，25g液态醋（5%酸度；1.25g乙酸）用35g水稀释；PILL，4片醋片（1.50g乙酸）与60g水一起整片吞服；以及PILL-c，4片碾碎的醋片溶解在60g水中。在空腹状态下以及餐后30分钟和60分钟检测毛细血管血糖。
60分钟血糖波动因处理方式而异（CON、VIN、PILL和PILL-c的iAUC分别为4.9±0.6、3.4±0.4、4.9±0.6和4.1±0.5mmol˖h/l；F(3,33)=3.037，P=0.043；重复测量方差分析）。事后分析显示，与CON和PILL相比，VIN的餐后血糖波动降低了31%（分别为P=0.040和P=0.049）。
这些数据表明，在年轻健康成年人用餐时整片服用市售醋片在降低餐后血糖波动方面不如液态醋有效。
