在流行病学研究中，开发一种以最少的时间和费用评估特定营养素膳食摄入量的方法具有相当大的兴趣。使用的数据从1682个人接受采访，使用广泛的食物频率饮食史，多少食物可能是最低限度的需要，以估计特定的营养素摄入量的流行病学目的的问题进行了检查。营养指数构建维生素A和C，膳食纤维，脂肪蛋白质，总热量的基础上，在采访中包括的128种食物。他们发现，这一人群中营养素摄入量的大部分变化可以用少量食物来解释。一个简短的饮食史，确定摄入少至15-20种食物可能是所有需要，以测试疾病的结果和单一营养素的摄入之间的关联。
There is considerable interest in developing a means of assessing dietary intake of specific nutrients with minimal time and expense in epidemiologic studies. Using data from 1682 individuals who were interviewed using an extensive food frequency dietary history, the question of how many foods might be minimally required in order to estimate specific nutrient intakes for epidemiologic purposes was examined. Nutrient indices were constructed for vitamins A and C, dietary fiber, fat protein, and total calories based on 128 foods included in the interview. They found that a large fraction of the variability of nutrient intake in this population could be explained by a small number of foods. An abbreviated dietary history ascertaining the intake of as few as 15-20 food items may be all that is required in order to test the association between disease outcome and the intake of a single nutrient.
