项目摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Our primary specific aim is to validate the CASI-DH and the DietDay against recovery and concentration biomarkers as follows: 1) To examine the validity of the CASI-DH and DietDay for assessing intakes of total energy in comparison to the total energy expenditure assessed through the doubly labeled water technique, a gold standard energy intake validation biomarker. 2) To examine the validity of the CASI-DH and DietDay for assessing intakes of total protein in comparison to PABA (para-amino benzoic acid) validated 24-hour sample measurements of urinary nitrogen for protein, a well-established protein intake biomarker and for dietary potassium using the same biological sample. 3) To examine the validity of the CASI-DH for assessing intakes of fruits and vegetables, in comparison to blood levels of carotenoids.

该副本是利用众多研究子项目之一由NIH/NCRR资助的中心赠款提供的资源。子弹和调查员（PI）可能已经从其他NIH来源获得了主要资金，因此可以在其他清晰的条目中代表。列出的机构是对于中心，这不一定是调查员的机构。我们的主要目的是验证CASI-DH和DIET日，以防止恢复和浓度生物标志物，如下所示： 1）与通过双重标记的水技术评估的总能量消耗相比，CASI-DH和DIET日的有效性评估了总能量的摄入量，这是金标准能量摄入量验证生物标志物。 2）与PABA（Para-Amino苯甲酸）相比，CASI-DH和DIET日的有效性评估了总蛋白质的摄入量，验证了24小时的样品测量尿氮的样品测量，用于蛋白质的尿氮，一种已建立的蛋白质摄入生物标记物和使用同一生物学样品的饮食中的蛋白质摄入量。 3）与类胡萝卜素的血液水平相比，要检查CASI-DH对评估水果和蔬菜摄入的有效性。
