饮食调查问卷是与计算机程序结合开发的，旨在向公众提供快速的营养反馈。该调查问卷根据 16 天的称重饮食记录以及血液和尿液中的生化变量进行了验证。问卷和称重记录之间获得的最高 Pearson 相关系数是酒精、纤维、铁、核黄素（r 分别为 0.74、0.67、0.66、0.66）。结果显示出显着的性别差异；女性中相关性较高的趋势持续存在。通过问卷调查，至少 65% 的受试者通过大多数营养素的称重记录被分类到分类的五分之一以内。
A diet questionnaire was developed in association with a computer program to provide rapid nutritional feedback to the general public. The questionnaire was validated against 16 d of weighed diet records and biochemical variables in blood and urine. The highest Pearson correlation coefficients obtained between the questionnaire and the weighed records were for alcohol, fibre, iron, riboflavin (r 0.74, 0.67, 0.66, 0.66 respectively). Striking sex differences were shown in the results; the trend for higher correlations persisted in females. At least 65% of subjects were classified by questionnaire to within one quintile of the classification by weighed record for the majority of nutrients.
