Abstract

Background: There has been growing attention towards personalizing dietary advice to the specific lifestyle, phenotypic and genotypic properties of consumers. Consumer acceptance and advice adherence is critical for the success of services offering personalized dietary advice. However, more insight is needed in the current body of knowledge on the determinants of consumer acceptance and use of personalized dietary advice. Scope and approach: This literature review provides an overview of the current knowledge on consumer acceptance, use and effectiveness of personalized dietary advice based on the four information flow stages in personalized dietary advice: (1) information provision from consumer to formulate a personalized dietary advice, (2) personalized advice generation, (3) advice provision to the consumer, (4) advice acceptance and adherence. Key Findings and Conclusions: Results show that the extent to which each step in the cycle is considered in the reviewed studies varies strongly, with most emphasis on the advice adherence, such as changes in dietary intake. In contrast, it is less clear how consumer data is used to generate a personalized dietary advice. Based on the studies in our review, we identify aspects that play a role in the consumer acceptance of personalized dietary advice and the best design practices for creating a successful personalized advice.
