What is the link between junk food advertising, obesity and cancer?

Overweight or obesity affects one in every four NSW children and a high proportion will go on to have excess body weight in adulthood; increasing the risk of cancer.  

So what is the link between junk food marketing and increased risk of cancer?


Food marketing influences children’s food preferences, encourages pestering for that food and even influences what they eat. Children are vulnerable and don't fully understand advertising.

The majority of foods currently promoted are unhealthy and that contradicts and undermines healthy eating messages.  Children who eat these foods are more likely to have overweight, once weight is gained it’s difficult to lose and they are more likely to have overweight in adulthood putting them at risk of many cancers.

Restricting exposure to junk food ads is one of the most cost-effective strategies to reduce childhood obesity rates and decrease the risk of cancer in adulthood.
