背景资料：基于营养素的建议是为人群定义的，但在个体水平上实现这些建议所需的饮食选择值得进一步探索。目的：目的是描述为实现人群中每个个体的营养建议所需的饮食变化。设计：为参加法国国家印加儿童营养评估的每个成年人专门开发了一个单独的饮食模型。（Enquete Individuelle et Nationale sur les Consummations Alimentaires）膳食调查（n = 1171）。从每个个体每周食物摄入量（观察饮食）开始，通过线性规划设计等热量模型饮食，以同时满足法国营养素推荐的32种营养素，同时与观察到的食物摄入量偏差最小。模拟饮食配对观察diets.Results：一个新的营养充足的饮食，为每个人。在一半的模拟饮食中，
Background: Nutrient-based recommendations are defined for populations, but the dietary choices needed to fulfill them at the individual level deserve further exploration.Objective: The objective was to describe the dietary changes needed to achieve nutritional recommendations for each individual of a population.Design: An individual diet model was specifically developed for each adult participating in the French national INCA (Enquete Individuelle et Nationale sur les Consommations Alimentaires) dietary survey (n = 1171). Starting from each individual weekly food intake (observed diets), an isocaloric modeled diet was designed by linear programming to simultaneously meet the French nutrient recommendations for 32 nutrients while deviating the least from the observed food intake. Modeled diets were paired with observed diets for statistical comparison.Results: A new nutritionally adequate diet was obtained for each individual. In half the modeled diets,
