It is because excessive nutrient intake can lead to internal organs failure, such as kidney damage. This study focuses on minimizing vitamin A’s intake in daily diet because vitamin A can give good vision, maintain healthy skin, and improve body's immune system. This research involves a few nutrients, such as calcium, iron, cholesterol, and vitamin A. The diet problem of minimizing vitamin A will be solved by using the graphical method and excel solver. The results are compared to determine which ways is the best. The results obtained are optimal solution, which is the minimal amount of vitamin A from one of the methods.endiet problem, linear programming, vitamin A, excel solverArticle48527Special Issue
