18 pages., via online journal, As food products marketed as “gluten-free” become increasingly popular, many consumers start to exclude sources of gluten (e.g., wheat, barley, and rye) from their diets for both medical and non-medical purposes. The grain industry is facing a growing challenge to (re)boost consumers’ confidence in the healthiness and safety of its commodities. Using 561 participants recruited from the Amazon Mechanical Turk workers’ panel, this study implemented a 2 (pretzels vs. potato chips) * 2 (positive- vs. negative- frame) * 2 (wheat image vs. no wheat image) experiment to examine the effects of gluten-free labels on consumers’ perceived healthiness and safety of wheat, perceived benefits of labeled products, and their evaluation of the shown labels. Results showed that consumers evaluate the gluten-free labels most positively when they appear on products that could have contained gluten. For products that are naturally gluten-free, adding a gluten-free label only decreased consumers’ confidence in such labels. The presence of gluten-free labels increased consumers’ perceived benefits of the labeled products when they do not contain any misleading information (e.g., image of a wheat head). However, some gluten-free labels could have negative impacts on consumers’ perceptions of the healthiness and safety of wheat. Overall, food producers and marketers might have undervalued consumers’ literacy and overestimated their susceptibility to marketing strategies. We discussed the implications for food marketers, regulators, and communicators.
8 pages., via online journal., Social media bring various stakeholders of the agro-food system together into a new playing field. This article reveals the dynamics of this playing field and the ways in which this can influence the governance of agro-food sustainability. We delineate three pathways that highlight the ways in which social media can have implications for the governance of agro-food sustainability; firstly, Hypes on agro-food sustainability issues, secondly, opportunities for the self-organization of food movements, and thirdly, data for new forms of agro-food governance. We conclude that while mass self-communication on social media forms an emergent force that disrupts agro-food governance, it also generates data that forms a resource for powerful players to regain control.
