This guide, developed with the project SEEDS, provides information on four important areas in teen lives: 1. healthy snacking, 2. physical activity, 3. sedentary behavior, and 4. screen time. SEEDS has been conducted with the citizen science approach involving teens together with researchers in all stages of the project. Teens are going through many physical changes that need to be supported by healthy behavior and a balanced diet. According to the World Health Organization (WHO), teenagers establish patterns of behavior — related to diet, physical activity, substance use, and sexual activity — that can protect their health and the health of others around them, or put their health at risk now and in the future. Exploring health issues in teens is the primary scope of the European project SEEDS that will be explained in the following pages.

SEEDS has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement 101006251. https://seedsmakeathons.com/
