Diet diversity indexes were examined as examples of qualitative diet indexes. Diet indexes were calculated from food frequency information grouped according to three food taxonomies or left uncategorized. Two diet indexes linked more closely in their construct to measures of nutrient intake were calculated for comparison purposes. The indexes were assessed on the basis of concordance with biochemical measures of vitamin nutriture, simplicity of calculation, and cultural and nutritional logic. The value of the diet indexes lay in their ability to describe, not to assess, food patterns.
饮食多样性指数作为定性饮食指数的示例进行了研究。饮食指数是根据按照三种食物分类法分组或未分类的食物频率信息计算得出的。为了进行比较，计算了两个在结构上与营养摄入量测量更紧密相关的饮食指数。这些指数是根据与维生素营养状况的生化测量结果的一致性、计算的简易性以及文化和营养逻辑进行评估的。饮食指数的价值在于它们描述食物模式的能力，而非评估食物模式的能力。
