Dietary control and nutrient intake are critical aspects of any metabolic study, but this is especially true in the case of bed rest studies. We sought to define nutritional requirements, develop menus, and implement them during long-duration head-down bed rest studies.
The dietary goals were to provide 100% of subjects' nutrient requirements and to maintain subjects' bodyweight to within 3% of their weight on the third day of head-down bed rest. The research dietitian and metabolic kitchen staff are an important part of the multidisciplinary team required to implement a bed rest study.
We report herein the planning steps and nutrient intake results from 13 subjects. We also provide insight into some of the dietary challenges that arise during long-duration bed rest studies.
Regardless of the overall objective of the bed rest study to be performed, nutrition must be carefully planned, implemented, and monitored to prevent results from being compromised.
饮食控制和营养摄入是任何代谢研究的关键方面，在卧床休息研究中更是如此。我们试图确定营养需求，制定菜单，并在长时间头低位卧床休息研究期间实施这些措施。
饮食目标是提供受试者100%的营养需求，并将受试者的体重维持在头低位卧床休息第三天体重的3%以内。研究营养师和代谢厨房工作人员是实施卧床休息研究所需的多学科团队的重要组成部分。
我们在此报告13名受试者的规划步骤和营养摄入结果。我们还深入探讨了长时间卧床休息研究期间出现的一些饮食挑战。
无论要进行的卧床休息研究的总体目标是什么，都必须精心规划、实施和监测营养，以防止结果受到影响。
