在双标记水研究中需要关于饮食的常量营养素组成的信息，以将测量的二氧化碳产生率转换为总能量消耗的值。然而，关于为此目的确定食物摄入量的最佳方法，没有普遍的共识。在10名年轻女性和10名老年女性的双标记水研究中，测试了四种常见的测量食物摄入量的方法（7天称重食物摄入量、24小时回忆和Fred哈钦森癌症研究中心/Block和Willett食物频率问卷）提供可比食物商和总能量消耗数据的能力。所有方法给出的总能量消耗的平均值彼此在1%以内。使用24小时回忆和食物频率问卷获得的个体值在使用7天称重食物记录数据确定的值的+/-3%（标准差）范围内。这些结果表明，在双标记水研究中，没有必要使用耗时且昂贵的7天食物记录;相反，通过24小时回忆或食物频率问卷更容易获得的食物摄入数据可以提供可比数据。
Information on the macronutrient composition of the diet is needed in doubly labeled water studies to convert measured rates of carbon dioxide production into values for total energy expenditure. There is no general consensus, however, about the best method to determine food intake for this purpose. Four common methods of measuring food intake (7-day weighed food intake, 24-hour recall, and Fred Hutchinson Cancer Research Center/Block and Willett food frequency questionnaires) were tested for their ability to provide comparable food quotient and total energy expenditure data in doubly labeled water studies in 10 young and 10 older women. All methods gave mean values for total energy expenditure that were within 1% of each other. Individual values obtained using the 24-hour recall and food frequency questionnaires were within +/-3% (standard deviation) of values determined using data from the 7-day weighed food record. These results suggest that it is not necessary to use time-consuming and expensive 7-day food records in doubly labeled water studies; instead, food intake data obtained more easily by 24-hour recall or food frequency questionnaire can provide comparable data.
