Modeling Eating Behaviors: the Role of Environment and Positive Food Association Learning via a Ratatouille Effect

TL;DR

This paper models how environmental factors and positive food association learning influence eating behaviors in children, suggesting that food association strategies may be more effective than traditional nutrition education in creating lasting healthy eating habits.

Contribution

It introduces a population-level model demonstrating the potential of food association learning to induce sustainable dietary behavior changes in communities.

Findings

Nutrition education alone has limited impact on eating behaviors.

Food association learning can lead to a 'Ratatouille' effect, transforming preferences.

Community-based strategies incorporating social and cultural factors are more effective.

Abstract

Eating behaviors among a large population of children are studied as a dynamic process driven by nonlinear interactions in the sociocultural school environment. The impact of food association learning on diet dynamics, inspired by a pilot study conducted among Arizona children in Pre-Kindergarten to 8th grades, is used to build simple population-level learning models. Qualitatively, mathematical studies are used to highlight the possible ramifications of instruction, learning in nutrition, and health at the community level. Model results suggest that nutrition education programs at the population-level have minimal impact on improving eating behaviors, findings that agree with prior field studies. Hence, the incorporation of food association learning may be a better strategy for creating resilient communities of healthy and non-healthy eaters. A \textit{Ratatouille} effect can be observed when food association learners become food preference learners, a potential sustainable behavioral change, which in turn, may impact the overall distribution of healthy eaters. In short, this work evaluates the effectiveness of population-level intervention strategies and the importance of institutionalizing nutrition programs that factor in economical, social, cultural, and environmental elements that mesh well with the norms and values in the community.
