The capability of “dish” and “ingredient in dish” modeling to reduce the number of nutrition imbalances in bioregenerative life support diet was compared. Masses of dishes were assumed to be the independent variables in the ‘dish’ model, while in the ‘ingredient in dish’ model the independent variables were the total masses of the ingredients in a one-day menu and masses of ingredients in the dishes. The objective function in both models was minimization of discrepancy between the calculated nutrition intakes and the daily nutrition requirements of NASA for long duration space missions.

Comparing of two models was carried out for the case of a one-day diet containing 12 dishes and 32 ingredients. It was established that the diet simulation by ‘dish’ model brings 6 nutrition imbalances. The use of the ‘ingredient in dish’ modeling has helped to reduce the number of nutrition imbalances to 3, namely, an excess of iron, vitamin A and saturated fat. Obstacles to the fulfillment of all nutrition requirements were the nomenclature and masses of ingredients in the dish recipes.

比较了“菜”和“菜中的成分”建模在减少生物再生生命支持饮食中营养失衡次数的能力。菜肴的质量被假定为“菜肴”模型中的自变量，而在“菜肴中的配料”模型中，自变量是一日菜单中配料的总质量和菜肴中配料的质量。两种模型中的目标函数都是将计算的营养摄入量与 NASA 长期太空任务的每日营养需求之间的差异最小化。

对包含 12 道菜和 32 种成分的一日饮食情况进行了两种模型的比较。确定了“dish”模型的饮食模拟带来了6种营养失衡。使用“菜肴中的成分”建模有助于将营养失衡的数量减少到 3 个，即铁、维生素 A 和饱和脂肪过量。满足所有营养要求的障碍是菜肴食谱中的命名和成分数量。
