饮食摄入量的估计不可能没有错误，而且可能永远不会。误差的性质和幅度取决于饮食数据收集方法和研究对象。特定类型的错误的影响取决于所提出的问题和用于解决ft的分析方法。这些现象的例子在这篇评论文章。未来在于改进对误差项的估计和理解，以及开发处理这些误差项的分析和统计方法，而不是饮食方法学本身的“改进”。
Dietary intake cannot be estimated without error and probably never will be. The nature and magnitude of the error depends on both the dietary data collection methodology and the subjects studied. The impact of particular types of error depends on the question being asked and the analytical methodology used to address ft. Examples of these phenomena are presented in this review paper. The future lies in improved estimation and understanding of the error terms and in the development of analytical and statistical methods of coping with these error terms rather than with ''improvements'' in dietary methodology per se.
