摘要

背景:我们之前的实验表明,晚上照射在受试者身上的光强度对第二天早上正常晚餐时摄入的膳食碳水化合物的消化和吸收效率没有影响。熬夜的人通常晚饭吃得很晚;因此,我们研究了较晚的晚餐时间对第二天早上胃肠活动的影响,并与正常的晚餐时间进行了比较。方法:12名女大学生自愿作为付费参与者。进行呼吸氢测试是为了估计未吸收的膳食碳水化合物的数量和早餐中未吸收的膳食碳水化合物总量的百分比,以及估计口腔-盲肠运输时间。还测量了呼吸商,以确定早餐后状态下碳水化合物/脂质代谢的比率。用血糖仪测量受试者外周血血糖浓度。受试者在两种不同的实验条件下参与:正常晚餐时间(18:00)和较晚晚餐时间(23:00)。结果:晚晚餐条件下早餐对膳食碳水化合物的消化吸收效率高于正常晚餐条件下。通常或较晚的晚餐时间对受试者早餐后氧化的碳水化合物与脂质的比例没有影响。在早餐后30、60、120、150和180分钟,两种情况下的血糖水平有显著差异,而晚餐后的平均血糖水平明显高于正常晚餐时的血糖水平。结论:晚吃晚餐对次日早晨餐后血糖的影响更大。这项研究证实,保持正常的用餐时间对我们的健康很重要。

Effects of a late supper on digestion and the absorption of dietary carbohydrates in the following morning.

Effects of a late supper on digestion and the absorption of dietary carbohydrates in the following morning.

Effects of a late supper on digestion and the absorption of dietary carbohydrates in the following morning.

Effects of a late supper on digestion and the absorption of dietary carbohydrates in the following morning.

Background: Our previous experiment showed that the light intensity exposed on the subjects during evening time had no effect in the following morning on the efficiency of the digestion and absorption of dietary carbohydrates ingested at a usual suppertime. People who keep late hours usually have a late suppertime; thus, we examined the effects of a late suppertime on gastrointestinal activity in the following morning in comparison to that of a usual suppertime.

Methods: Twelve female university students volunteered as paid participants. The breath hydrogen test was carried out to estimate the amount of unabsorbed dietary carbohydrates and the percentage of the total amount of dietary carbohydrates in the breakfast that were unabsorbed, as well as to estimate oro-cecal transit time. The respiratory quotient was also measured to find the ratio of carbohydrates/lipid metabolism in the post-breakfast state. Subjects' peripheral blood glucose concentration was measured by a blood glucose meter. The subjects participated under two different experimental conditions: with a usual suppertime (having supper at 18:00) and a late suppertime (having supper at 23:00).

Results: The efficiency of the digestion and absorption of dietary carbohydrates in the breakfast under late suppertime conditions was higher than that under usual suppertime conditions. Usual or late suppertime had no effect on the ratio of carbohydrates to lipids oxidized after the subjects had breakfast. There were significant differences in the blood glucose level between the two conditions at 30, 60, 120, 150, and 180 minutes after having breakfast, whereas the mean blood glucose level under late suppertime conditions was significantly higher than under usual suppertime conditions.

Conclusions: Having a late supper showed a worse effect on postprandial serum glucose profiles the following morning. This study confirmed that keeping our usual meal timing is important for our health.

期刊介绍: Journal of Physiological Anthropology (JPA) is an open access, peer-reviewed journal that publishes research on the physiological functions of modern mankind, with an emphasis on the physical and bio-cultural effects on human adaptability to the current environment. The objective of JPA is to evaluate physiological adaptations to modern living environments, and to publish research from different scientific fields concerned with environmental impact on human life. Topic areas include, but are not limited to: environmental physiology bio-cultural environment living environment epigenetic adaptation development and growth age and sex differences nutrition and morphology physical fitness and health Journal of Physiological Anthropology is the official journal of the Japan Society of Physiological Anthropology.
