Managing healthy eating: definitions, classifications, and strategies.

This study sought to enhance understanding of how people conceptualize and manage healthy eating. An interpretivist approach employed the constant comparative method to analyze 79 open-ended interviews with individuals about food choices and eating behaviors for health-related themes. Participant reports depicted cognitive systems for defining healthy eating, where personal meanings evolved through ongoing exposure to a variety of experiential and informational sources. Participants' definitions of healthy eating clustered around seven themes forrelating food and eating to their personal health. Healthy eating definitions shaped how participants categorized food and eating situations as healthy and unhealthy. Participants described healthy eating strategies that were differentially associated with various healthy eating themes. These findings provide an emic perspective of how a diverse sample of adults conceptualize and manage healthy eating. Exposing the implicit and multiplistic nature of healthy eating conceptions provides information useful to health educators promoting behavior changes.

Food choice: a conceptual model of the process.

Interviews examining the food choice process were conducted with 29 adults, primarily individuals making grocery store food choice decisions, who were sampled for their diversity. These people were asked about how they chose foods when shopping and in other settings, and what influenced their choices. Verbatim transcripts of the interviews were analysed using qualitative methods that included constant comparison, concept mapping, and case summaries, and a conceptual food choice process model was developed. Data from the interviews are presented to illustrate the structure of this conceptual model. People's life course experiences affected major influences on food choice that included ideals, personal factors, resources, social contexts and the food context. These influences informed the development of personal systems for making food choices that incorporated value negotiations and behavioral strategies. Value negotiations weighed sensory perceptions, monetary considerations, health and nutrition beliefs and concerns, convenience, social relationships and quality of food choice decisions. Strategies employed to simplify the food choice process developed over time. The conceptual food choice process model represents the rich and complex bases of food practices, and provides a theoretical framework for research and practice in nutrition.
