We use the registered diet data after we agreed to use their data to develop the application. ※ The menu list of this application is based on dietary records from a 3-day weighing of 1,071 participants in the National Institute for Longevity Sciences-Longitudinal Study of Aging. The program that could check the food balances was developed using a menu list. It is confirmed in a study that energy and nutrient intakes are easily checked when using this program (T Imai etc. The Japanese Journal of Nutrition and Dietetics, 67（6）:301- 309、2009 in Japanese). This application was created by female college students who studied nutrition and dietetics at the Doshisha Women’s College of Liberal Art (D.W.C.L.A) based on the program. We developed the application with photographs of the menu, and advice of black cat. This application developed an evidence based finding to return the results of research to society.
