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.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目和 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 我们的主要具体目标是针对恢复和浓度生物标志物验证 CASI-DH 和 DietDay，如下所示： 1) 检验 CASI-DH 和 DietDay 在评估总能量摄入方面的有效性，并与通过双标记水技术（一种金标准能量摄入验证生物标记）评估的总能量消耗进行比较。 2) 与 PABA（对氨基苯甲酸）相比，为了检验 CASI-DH 和 DietDay 在评估总蛋白质摄入量方面的有效性，使用相同的生物样品对尿蛋白氮（一种成熟的蛋白质摄入生物标志物）和膳食钾进行 24 小时样本测量。 3) 与类胡萝卜素的血液水平相比，检查 CASI-DH 评估水果和蔬菜摄入量的有效性。
