摘　　要：为探究不同水果餐前负荷的效果差异,募集10位年轻超重受试者,以含15 g可利用碳水化合物的苹果、甜橙或梨为餐前负荷食物,以含50 g可利用碳水化合物的白米饭为正餐食物,测定各测试餐后180 min内的血糖和饱腹感水平,以及3种水果的营养成分和质构特性。结果表明:餐前负荷3种水果均可显著降低餐后血糖波动幅度,其中,苹果和甜橙分别使每克可利用碳水化合物引起的血糖增加值显著降低27.3%和34.1%。餐前负荷水果对餐后饱腹感无显著影响。结论:白米饭餐前30 min负荷3种水果,均有益于平缓餐后血糖反应,其效应可用水果成分及质构特性来解释。To investigate the impact of different fresh fruits preloads on acute postprandial glycemic and satiety responses,10 young overweight volunteers consumed apple,orange or pear preload containing 15 g available carbohydrates before a rice meal containing 50 g available carbohydrates.The postprandial blood glucose and satiety parameters in 180 min as well as the texture properties and chemical composition of the three fruits were measured.The results indicated that all fruit preloads decreased the maximum amplitudes of glycemic excursion significantly compared with the control group.Apple and orange preload achieved 27.3%and 34.1%reduction of the area under glycemic curve contributed by per gram of available carbohydrate.The self-reported satiety scores did not differ significantly among test meals and the control meal.In conclusion,this study demonstrated that preloading of 3 fruits 30 min before white rice meal could mitigate postprandial glycemic response in young overweight subjects,while the effect might partly be explained by the composition and texture characteristics of fruits.
