Personalized Nutrition Recommendations in Food Services

The nutritional information on food services could be part of a public health policy against the increasing rate of obesity. The aim of this work is to present the state of art for the nutritional information on food services and the mHealth application usage, worldwide. A particular case study is presented that refers to an Electronic Intelligent System of Personalized Dietary Advice (DISYS) for tablets and smartphones. This application provides nutritional analysis of menu items and personalized suggestions according to the nutritional demands of each customer. The application was characterized as an easy-to-use, comprehensive, and useful tool. Volunteers considered that this application contributes to overall health by enabling the modulation of body weight throughout healthier choices, reduction of calorie intake, and self-monitoring. mHealth applications designed to provide nutritional information seem to be useful for customers as they recommend appropriate nutritional options. They are an effective tool for caterers and nutritionists, who can provide value-added services.
