Within the special project, supported by Health Insurance Institute of Slovenia we have developed special mobile app which serves as personal consultant in the field of proper nutrition. The application is based on expert dietary starting points and based on the person’s lifestyle data it calculates the individual’s need for nutrients. For the functioning of the Food navigator there was a special database of foods developed, which is constantly upgraded. For each food type are available data on fat, protein and carbohydrates. The database consist also some other data like content of vitamins and minerals, but at this stage that info is not yet displayed in the printout of daily values.
