当与教育相结合时,单谷氨酸 (MSG) 可能会增强蔬菜的味道并增加摄入量. 这一策略显示了改善饮食习惯的希望,尽管需要进一步的研究.
科学领域:
- 营养科学 营养科学
- 食品科学 食品科学 食品科学
- 公共卫生 公共卫生
背景情况:
- 饮食指南强调增加对健康的蔬菜消费.
- 增味是一种改善蔬菜摄入量的潜在策略.
- 医学课程将营养教育与技巧相结合.
研究的目的:
- 评估单谷氨酸 (MSG) 作为增加蔬菜摄入量的风味增强剂.
- 在随机对照试验 (RCT) 中将MSG与化 (NaCl) 进行比较.
- 评估数字医学教育计划对蔬菜消费的影响.
主要方法:
- 一个两个阶段的RCT涉及60-88名参与者超过9个月.
- 参与者被分配到使用100% NaCl,50/50 NaCl/MSG或70/30 NaCl/MSG调味料的组.
- 蔬菜摄入量是通过MyFitnessPal记录的;口感性是使用利克特秤和三角测试来评估的.
主要成果:
- 50/50 NaCl/MSG 组的蔬菜摄入量略有增加 (1.46 至 1.55 杯/天),而 NaCl 组的蔬菜摄入量略有减少 (1.33 至 0.95 杯/天).
- 偏好测试倾向于MSG调味的蔬菜,特别是50/50混合的绿豆 (p=0.07).
- 蔬菜摄入量的差异没有统计学意义 (p=0.46).
结论:
- 单谷氨酸 (MSG) 显示出增强蔬菜味道和摄入量的潜力.
- 将MSG与医学教育相结合可能是改善饮食的可行策略.
- 需要进一步的研究来证实MSG在增加蔬菜消费方面的有效性.
