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.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 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： 第一章 检查CASI-DH和DietDay用于评估总能量摄入的有效性，并与通过双标记水技术（一种金标准能量摄入验证生物标志物）评估的总能量消耗进行比较。 （二） 检查CASI-DH和DietDay用于评估总蛋白质摄入量的有效性，并与PABA（对氨基苯甲酸）验证的24小时尿氮样本测量值进行比较，PABA是一种公认的蛋白质摄入量生物标志物，使用相同的生物样本测量膳食钾。 第三章 检验CASI-DH评估水果和蔬菜摄入量的有效性，并与血液中类胡萝卜素水平进行比较。
