By genetic modification, the production of pest resistant crops could be significantly increased. However, there are concerns that those GM foods may threaten people’s health and damage the environment in the long run. In the age of digital media, sources of health information for the public are multiple and complicated. People may receive news from televisions, Internet and newspapers. These media, such as news media, popularizing science websites, alternative/independent, specific organizations, to personal websites, blogs, and Facebook, varied in terms of their communication goals. However, they may deliver information about food, health and science, and their perspectives may also be very different. The disputes over GM foods controversies not only existed within scientific communities, but also extended to mass media which lay people are easily to access. Therefore, it is necessary to explore the media construction of GM foods among varied media, the relationship of information producers and the constructions, and the association between people’ media exposure and their attitudes, purchase behaviors toward GM foods, and civic participation of related issues and activities. This three-year study aims to (1) Compare the differences in GM food discourses among media (e.g. traditional news media, popular science media, alternative/ independent nonprofit organizations), (2) Explore the relationship between communicators/ writers’ role perception and goals and their construction on GM foods in various media, and (3) Analyze how lay people’s media exposure experiences, social trust to GM food related stakeholders, value of technology, and risk/benefit perceptions affect their attitudes, purchase behaviors, and civic participation toward GM foods.
