Chronic kidney disease (CKD) is a very common disease in the Philippines. Some of its main causes are hypertension and diabetes. This study is aimed to develop an optimal food dietary model from ninety (90) combinations of linear programming models for adult Filipino patients with Stage 1 or Stage 2 Chronic Kidney Disease. This process will search for the lowest possible cost of their daily food plan while satisfying their daily nutritional requirements. The diet contains six nutritional requirements which are protein, sodium, potassium, phosphorous, calcium and calories. The thirteen cooked food commodities are the following: pork, milkfish, chicken, tilapia, egg, white rice, roasted green beans with garlic, sautéed cabbage, stir-fry bitter gourd, coconut meat, avocado, mango, and oat bran. Using the selected linear programming model which consist of chicken, tilapia, white rice, roasted green beans with garlic, stir-fry bitter gourd, coconut meat, and oat bran, the minimized daily dietary plan cost for adult male is ₱134.23, and adult female with ₱133.20.
