Digital health technologies are becoming increasingly prevalent to support self-care practices aiming to enhance people’s health and wellbeing. However, their potential to promote healthy eating practices among families including children has been limited.

The main objectives are: - Make a review of existing technology-enhanced support to promote healthy eating practices e.g., a feature assessment and a ranking of these features - Conduct user studies with a particular target group you would like to focus based on the review to gather user requirements and to evaluate the early designs of the application --see below. -Propose, Design and Evaluate an Interactive Prototype (e.g., mobile, web, physical computing, and/or game, etc.) that can promote healthy eating practices for either the whole family or for any member of the family including children, older adults, pregnant women, etc. based on the results of the review
