Optimization Study on the Evaluation and Design of College Students' Dietary Recipes based on the Planning Model

In this paper, the optimal design and evaluation of college students' diet recipes were studied. Using the planning model method, a multi-objective optimization model was constructed with the goal of optimal protein and amino acid score and the most economical meal cost. Firstly, by establishing the objective function with protein amino acid score as the main index, combined with the principle of balanced diet optimization design, the daily diet of male university students and female university students was designed, and the dietary nutrition evaluation was carried out. Secondly, in order to pursue the economy of meal cost, an optimization model with cost minimization as the objective function was constructed, and the corresponding reasonable diet was obtained. Finally, to meet the needs of users to pursue nutrition and economy at the same time, a multi-objective optimization model was further constructed, which considered protein and amino acid scores and economy, and provided daily and weekly diet choices that were both nutritious and economical for college students.
