使用人类餐后模型探索不同脂肪:碳水化合物饮食排列对胃排空和代谢状态的影响
该临床试验的目的是使用健康受试者的人类餐后模型,研究由脂肪和碳水化合物 (CHO) 质量以及不同的宏量营养素分布(CHO:脂肪)调节的膳食对肠道生理和代谢结果的影响。
它旨在回答的主要问题是:
- 不同多不饱和/饱和(P/S)比、血糖生成指数和常量营养素含量的膳食成分如何影响血脂和血糖?
- 不同P/S比、血糖指数和常量营养素含量的膳食成分如何影响胃排空?

详细说明
该研究的目标将通过一项随机交叉研究进行测试,该研究包括 16 次饮食轮换,间隔至少一周的冲洗期。 所有招募的受试者将被随机分为 2 组,每组 7 人,即 HGI 和 LGI,每组内进行 9 次饮食轮换。 该研究设计将是一项交叉试验,相同的受试者接受所有类别的饮食轮换。 受试者将对每次旋转所使用的测试脂肪不知情。 每次餐后挑战之前都会记录体重测量结果,以尽量减少测试轮换之间的体重波动。
学习程序
口服葡萄糖耐量测试 (OGTT) 课程
在测试膳食轮换之前和结束时,受试者将在泰莱大学或 Cancellor Tuanku Muhriz 医院 (HCTM) 随机进行 2 次口服葡萄糖耐量测试 (OGTT),并使用葡萄糖参考饮料,无需 MRI 检查,以获得平均值每个受试者的血浆葡萄糖和胰岛素标准。 葡萄糖参考饮料组合物将为50g无水葡萄糖与250mL室温水的混合。 将在0、15、30、60、90,120和180分钟依次采集血样。
- 测试用餐时间
在每次餐后测试餐轮换期间,受试者将食用测试餐,然后在 Cancelor Tuanku Muhriz 医院 (HCTM) 的 MRI 中心进行 MRI 扫描。 对于预定的会议,将建议受试者在每次餐后活动前 24 小时内避免剧烈的体力活动、高热量或快餐、补充剂和咖啡摄入。 受试者将于上午 7:30 和 8:30 到达临床中心, 12 小时过夜禁食后。 到达中心后,受试者将休息 10 分钟,然后进行体重、血压和自我监测血糖 (SBMG) 测量。 随后,将根据研究目标抽取血液样本进行代谢研究。 在测试进餐前后 0(空腹)、15、30、60、90、120、180、240 和 300 分钟进行连续餐后 MRI 扫描。
