Abstract
Nutrition knowledge presumably influences human food behavior. However, previous research, much of which lacks an explicit theoretical foundation, has failed to verify a strong relationship. This paper describes an information processing approach that provides a conceptual foundation for explaining the effects of people's nutrition knowledge on their food behavior. This perspective focuses on the psychological processes involved in acquiring nutrition information, storing it in memory, retrieving it at a later time, and using nutrition knowledge in decision-making. This paper also presents a research strategy based on the information processing approach. Multiple measures of the content and organization of consumers' nutritional knowledge structures must be developed. Next, the reliability and validity of these indices must be established. Further research may examine how different types of knowledge structures are related to the use of new nutrition information for making correct food choices. The results of such research has the potential to help nutrition educators and policymakers develop more effective nutrition information programs.
