在食物营养素度量法的构建过程中,需要考虑多个问题,如:限制性和推荐性营养评价指标的选择、参考摄入量的选择、计算基准的选择、阈值或评分算法的选择,以及对评价方法的测试和验证等,其中,计算基准的选择是一个特殊的问题。本文将对营养素度量法建立体系中计算基准的选择进行综述。食物营养素度量法的定义是根据食物的营养成分组成对食物进行分类的科学~([1])。营养素度量法是根据广泛被认可的关于膳食和健康的科学知识,以需要限制的营养素、已知的对健康
Several issues need to be considered in the construction of a food nutrient metric, such as the selection of restrictive and recommended nutritional indicators, the choice of reference intake, the choice of baseline, the choice of threshold or scoring algorithm, Evaluation method of testing and verification, among them, the choice of calculation basis is a special problem. This article reviews the selection of the basis for the calculation of nutrients in the system of measurement. Food nutrient metrics are defined as science that classifies food according to its nutrient composition (1). Nutrient metrology is based on the widely accepted scientific knowledge about diet and health, with nutrients that need to be limited, known to be health
