Summary

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.

0:00.0	Hello and welcome to Sigma Nutrition Radio. This is episode 461 of the podcast. I am your host, Danny Lennon, and you are very welcome.
0:25.8	For those of you who are regular listeners, you will know that we've been on a pretty good run of
0:30.6	episodes lately, that we've been getting some great feedback about a couple of weeks ago,
0:35.4	Dr. Priya Smith ran on to talk about some of the models around
0:40.3	body mass regulation, obesity treatment, and some of the drugs in that area. And then last week,
0:45.8	for those of you who have a premium subscription, you would have heard our episode called
0:50.6	The Death of Domain Expertise, which has been something that has proved quite a bit of a hit.
0:57.0	So thank you for all of the kind feedback about that.
1:00.4	And if you are currently listening on the public feed, you can go and listen to a 30-minute preview of that episode in your feed right now.
1:10.0	On to today's episode, and we're going to be talking all
1:13.8	about food marketing and food advertising and its impact on eating behavior, particularly as it
1:19.6	relates to children and adolescents and then be taking some elements from that and applying
1:25.7	them broadly as well. So we have this really interesting research
1:31.2	base looking at food marketing, how it impacts things like preferences or likelihood of consuming
1:38.9	certain types of foods or eating behavior. And we then have a large body of evidence around the epidemiology looking
1:46.3	at food marketing exposure and how that may lead to things like higher obesity rates. But
1:52.2	there are still many open questions that people have, or at least some of these things are not
1:56.2	immediately clear. And oftentimes we have the food industry that pushes back against these and makes counter
2:02.1	arguments as if to say this evidence is quite weak. So what can we actually take from it? What does
2:08.9	the current evidence tell us about the exact effect of marketing on food choices? And beyond that,
2:15.2	what strategies are likely to yield the best results in terms
2:19.3	of mitigating the harms of food marketing on eating behavior, particularly in children and
