A food intake pattern specifying amounts and types of food was created for Canada's revised food guide, Eating Well with Canada's Food Guide (2007), using a two-step modeling process. In step one, food composites were manipulated to develop a food intake pattern. The second step used the step one food intake pattern to create 500 simulated diets for each of 16 age and gender groups. The resulting nutrient content distributions were evaluated relative to Dietary Reference Intake reference values. The modeling cycled between these two steps until a satisfactory pattern was achieved. The final pattern reflects modeling, a review of associations between foods and chronic disease, and input received during consultation.
通过两步建模过程,为加拿大修订后的食物指南《加拿大食物指南:健康饮食(2007年)》制定了一份规定食物数量和种类的食物摄入模式。第一步,对食物组合进行调整以形成一种食物摄入模式。第二步,利用第一步的食物摄入模式为16个年龄和性别组中的每一组创建500种模拟饮食。将所得的营养素含量分布与膳食参考摄入量参考值进行比较评估。该建模在这两个步骤之间循环,直至获得令人满意的模式。最终模式反映了建模过程、对食物与慢性病之间关联的审查以及咨询过程中收到的意见。
