In this study, online teaching materials were developed for consumers to help them understand
scientifically the validity of milk and health, focusing on the "milk harmful theory." According to the results of the preliminary survey, approximately 40% of the general consumers responded that they had heard about the "milk harmful theory." In order to prevent consumers from falling into such claims, educational materials were also developed to aid them in understanding the difference between causal relationships and correlations. Moreover, this will also help them in understanding milk production. The effectiveness of these teaching materials was verified through a randomized controlled trial using crowdsourcing. In this study, the result with a maximum effect size of 1.99,95% CI [1.69, 2.29] was obtained.
