目的：预测，对于法国妇女，成本限制对提供营养充足的饮食所需的食物选择的影响。设计：在线性规划中对满足适口性和营养约束的等热量日常饮食进行建模，使用不同的成本约束水平。对于每种模型饮食，与观察到的法国人口平均食物组模式（“观察到的平均饮食”）的总偏差被最小化。结果：为了在不受成本限制的情况下达到营养建议，与“平均观察饮食”相比，模型饮食提供了更多来自鱼类、新鲜水果和绿色蔬菜的能量，而来自动物脂肪和奶酪的能量更少。引入和加强成本限制减少了肉类、新鲜蔬菜、新鲜水果、植物脂肪和酸奶提供的能量，增加了加工肉类、鸡蛋、内脏和牛奶提供的能量。对于成本最低的饮食（即（sic）3.18/d），需要从“平均观察饮食”中进行明显的改变，包括从新鲜水果（-85%）和绿色蔬菜（-70%）中显著减少能量，从坚果、干果、根茎类、豆类和果汁中增加能量。启示：对低收入法国妇女的营养教育必须强调这些负担得起的食物选择。
Objective: to predict, for French women, the impact of a cost constraint on the food choices required to provide a nutritionally adequate diet.Design: Isocaloric daily diets fulfilling both palatability and nutritional constraints were modeled in linear programming, using different cost constraint levels. For each modeled diet, total departure from an observed French population's average food group pattern ("mean observed diet") was minimized.Results: To achieve the nutritional recommendations without a cost constraint, the modeled diet provided more energy from fish, fresh fruits and green vegetables and less energy from animal fats and cheese than the "mean observed diet." Introducing and strengthening a cost constraint decreased the energy provided by meat, fresh vegetables, fresh fruits, vegetable fat, and yogurts and increased the energy from processed meat, eggs, offal, and milk. For the lowest cost diet (ie, (sic)3.18/d), marked changes from the "mean observed diet" were required, including a marked reduction in the amount of energy from fresh fruits (-85%) and green vegetables (-70%), and an increase in the amount of energy from nuts, dried fruits, roots, legumes, and fruit juices.Implications: Nutrition education for low-income French women Must emphasize these affordable food choices.
