The nutritional component indexes two or more selected from a sodium/potassium ratio indicating a ratio, a magnesium/creatinine ratio, an urea-nitrogen/creatinine ratio, and a sodium/creatinine ratio. The determination control unit compares the spot urine nutritional component index with a reference value preset for the spot urine nutritional component index for each of spot urine nutritional component indexes, and determines whether or not the spot urine nutritional component index is equal to or more than the reference value. The decision control unit decides a diet evaluation pattern indicating a balance of the diet of the human from the determination result for each of the determined spot urine nutritional component indexes. The output control unit outputs a diet evaluation comment improving the balance of the diet of the human.
