我们假设早餐吃鸡蛋会显著降低餐后饱腹感和全天的能量摄入。使用交叉设计，21名男性，20至70岁，消耗2个等能量测试早餐，在一个随机的顺序分开1周。测试早餐的常量营养素组成如下：（EGG，% CHO/脂肪/蛋白质= 22：55：23）和（BAGEL，% CHO/脂肪/蛋白质= 72：12：16）。在试验早餐前基线和早餐后30、60、120和180分钟抽取空腹血样。180分钟后，给受试者提供自助午餐，并要求他们吃到满意为止。受试者在每次抽血期间填写视觉模拟量表（VAS），并记录测试早餐前后的食物摄入量。在每个时间点分析血糖、胰岛素和食欲激素。与BAGEL早餐相比，EGG早餐后受试者消耗的卡路里较少（P <0.01）。此外，与EGG早餐相比，受试者在BAGEL早餐后24小时内消耗了更多的卡路里（P <0.05）。基于VAS，与EGG早餐相比，BAGEL早餐后3小时受试者更饥饿，满意度更低（P <0.01）。参与者的血糖曲线下面积较高（P <0.05），BAGEL组的ghrelin和胰岛素曲线下面积也增加（P <0.05）。这些发现表明，早餐吃鸡蛋会导致血糖和胰岛素变化较小，胃饥饿素反应受到抑制，能量摄入减少。(C)2010年爱思唯尔公司All rights reserved.
We hypothesized that consuming eggs for breakfast would significantly lower postprandial satiety and energy intake throughout the day. Using a crossover design, 21 men, 20 to 70 years old, consumed 2 isoenergetic test breakfasts, in a random order separated by 1 week. The macronutrient composition of the test breakfasts were as follows: (EGG, % CHO/fat/protein = 22:55:23) and (BAGEL, % CHO/fat/protein = 72:12:16). Fasting blood samples were drawn at baseline before the test breakfast and at 30, 60, 120, and 180 minutes after breakfast. After 180 minutes, subjects were given a buffet lunch and asked to eat until satisfied. Subjects filled out Visual Analog Scales (VAS) during each blood draw and recorded food intake the days before and after the test breakfasts. Plasma glucose, insulin, and appetite hormones were analyzed at each time point. Subjects consumed fewer kilocalories after the EGG breakfast compared with the BAGEL breakfast (P < .01). In addition, subjects consumed more kilocalories in the 24-hour period after the BAGEL compared with the EGG breakfast (P < .05). Based on VAS, subjects were hungrier and less satisfied 3 hours after the BAGEL breakfast compared with the EGG breakfast (P < .01). Participants had higher plasma glucose area under the curve (P < .05) as well as an increased ghrelin and insulin area under the curve with BAGEL (P < .05). These findings suggest that consumption of eggs for breakfast results in less variation of plasma glucose and insulin, a suppressed ghrelin response, and reduced energy intake. (C) 2010 Elsevier Inc.
