This research is intended to analyze optimum nutrition of renal patients in fuzzy environment. One of the important factors in optimized nutrition of renal patients is the daily amount of received nutritious materials. High consumption of proteins, phosphor, salt and potassium enhances the disability of kidneys in these patients. There are several factors for which the accurate determination of nutritious materials present in different foods is impossible. Our purpose in this paper is to present a proper diet model for renal patients in the fuzzy environment. In most studies the daily nutrient intake decisions were made based on crisp data. By prescribing a diet based on crisp data, some of realities are neglected. For the same reason, we dealt with renal patient's diet problem through fuzzy approach. we have provided diet problem as multi-objective fuzzy linear programming problem in which minimization of Protein, Phosphor, Sodium, Potassium are considered as our objectives. Results indicated uncertainty about amount of nutrients and their intake affects diet quality making it more realistic. This research consists of two parts. In the first part, multi-objective fuzzy linear programming problem was investigated and in the second part, practical example of multi-objective fuzzy linear programming problem in relation to optimized diet of human will be presented and solved.
