Nutrition Recommendation for Elderly Using Mobile Application

Abstract

This research is for the development of mobile applications. The objective is to recommend nutrition that is suitable for the individual characteristics of the elderly and to increase dietary choices. The mobile application contains: 1) keeping track of daily calories and other relevant values 2) food and exercise recommendations based on the K-Nearest Neighbor (KNN) principle 3) recording of daily food and drink items 4) a self-nutrition overview report. The system has been developed as a mobile application on the iOS operating system for ease of use, and the results of the experimental program were tested with a sample of 30 elderly people. From the assessment, it was found that the developed system was able to recommend good nutrition for food. Overall satisfaction was at a good level (= 4.25). The elderly can choose the appropriate food, both in calorie content and nutritional value, by themselves. This is beneficial if eating a healthy diet is combined with exercise. Limiting the amount of food and receiving complete nutrients each day will result in the body's being able to burn excess energy more efficiently.
