The goal of this clinical trial is to investigate the effectiveness of linguistically tailored messages for promoting plant-based food choices in adolescents. The main question it aims to answer is: • Are linguistically tailored messages more effective in promoting plant-based eating compared to a) non-tailored messages (active control), and b) not receiving messages at all (passive control)? Researchers will compare participants exposed to linguistically tailored messages, non-tailored messages, and no messages to determine if linguistic messages are more effective in promoting plant-based food choices. Participants will receive daily messages promoting a plant-based diet from Monday to Friday for two weeks, accompanied by daily and weekend surveys about their food choices and message perception.
