Research on the Dietary Allocation Strategy of College Students Based on the Planning Model

The nutrients to maintain human daily needs are: protein, sugar, fat, minerals, vitamins, food cellulose and water 7 categories, a total of about 40 kinds. And the nutritional element components each kind are different, regulating effect on physiologic function body is also so variety foods must be matched in proportion, order meet demand elements needed by body. Reasonable nutrition emphasizes that supplied consumption should complete, moderate content appropriate proportion. For this situation, paper, contemporary college students, for example, study problem students how scientific diet, basis Chinese residents dietary guidelines, balance principle, lists food, nutrient content, with best most economic ratio as ultimate goal, establish target model based linear planning. model, using Matlab, computational software optimizes module, establishing optimal objective function. Through reasonable assumption calculation, parameters nonlinear planning optimized then obtained, more economical balanced strategy put forward.
