The authors briefly review some problems encountered in collecting and interpreting dietary data and in analyzing them by hand and by computer methods. The use of computers, meant to speed processing, has often delayed processing or merely replaced computation time with coding time. The authors describe a simplified nutrient data base and an interactive retrieval method, Quick Input of Food, which has been developed for direct use by nutritionists with their clients.
作者简要回顾了在收集和解释饮食数据以及通过手工和计算机方法进行分析时遇到的一些问题。使用计算机本应加快处理速度，但却常常导致处理延迟，或者只是用编码时间取代了计算时间。作者描述了一种简化的营养数据库和一种交互式检索方法——食物快速输入法，该方法是为营养师直接与客户一起使用而开发的。
