Nudging consumers toward healthier diets: Evidence from the Food Choice App in India
研究基于食品选择应用程序，通过行为改变沟通和女性赋权，在收入冲击下如何影响低收入家庭饮食规划，发现预算约束导致碳水化合物优先，但干预能显著提高蛋白质密度。
Abstract We develop the Food Choice App (FCA) based on the Gastronomic Systems Research (GSR) framework to study how behavioral change communication (BCC) on healthier diets influences diet planning under income shocks. A sample of 192 low- and middle-income households in West Bengal use the FCA to plan their diets by allocating a randomized weekly food budget among 162 Bengali dishes across five eating occasions over seven weekdays. Budget constraints drive carbohydrate prioritization, but BCC exposure and women’s empowerment significantly increase dietary protein density. Findings underscore the importance of targeted nudges across multiple levels of the Gastronomic System to promote healthier diets.
