Our Apples are Healthier than your Apples: Deciphering the Healthiness Bias for Domestic and Foreign Products
研究发现消费者认为本国食品比外国食品更健康、更天然，这种偏见在多个食品类别中成立，但产品有健康风险或双重国籍时消失。
This study extends previous research by exploring perceptions of healthiness in the international food marketplace. To this end, it aims to fill an important gap by shedding light on the role of country of origin in shaping perceptions of healthiness. The authors provide evidence that domestic and foreign food products elicit different perceptions of healthiness. Consumers choose domestic products because they perceive them as healthier and more natural. The effect holds across different samples and product categories (apples, tomatoes, bread, and yogurt). However, this healthiness bias vanishes when products are presented as posing health risks and when products are introduced with a dual identity (i.e., both foreign and domestic). Researching these health-related effects helps provide a better understanding of consumer attitudes toward domestic- versus foreign-made food products.
