#461: Prof. Emma Boyland – How Food Marketing Impacts Eating Behaviour

---

Introduction

Research has shown that food marketing strongly impacts children’s eating behaviour. Marketing influences food purchase requests, purchases, and preferences.

And the evidence of a relationship between food marketing exposure and obesity meets epidemiological criteria for causality. The evidence suggests that the impact of food marketing is a function of both exposure to the marketing message and its persuasive power.

What does the current evidence tell us about the exact effect of marketing on food choices? And beyond that, what strategies are likely to yield the best results in terms of mitigating the harms of food marketing on eating behaviour, particularly in children and adolescents?

To help answer these questions, subject area expert Prof. Emma Boyland is on the podcast to discuss what is currently known.
