nutrient requirement, linear programming, dietary plan

In this paper, we analyse daily nutrient requirements of an individual person from the point of view of the nutrition adviser. The goal is to simplify the adviser?s menu planning for a client as much as possible. After that, we design an individual eating plan for a week using a new linear optimization model. The model respects eating habits and it follows the client?s or adviser?s recommended recipes taking the compatibility of foods into account. The model involves linear constraints to ensure that two incompatible foods are not used in the same course. The model comprises further constraints to guarantee the diversity of the courses. The purpose of other constraints is to use an exact amount of some food, e.g. one whole egg or 100 grams of cheese, during the week. The model is made up so that the final dietary plan for the client is as natural as possible. The model gives recommended amounts of foods for weekly recipe planning.
