About 200,000 NSW children use the train or bus daily. On these journeys they are exposed to plenty of advertising.
One in every five NSW children are overweight or obese and a high proportion will go on to become overweight adults, 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 ultimately influences what they eat. Children are vulnerable and don't fully understand advertising.
The majority of foods currently promoted are unhealthy and this contradicts and undermines healthy eating messages. Children who eat these foods are more likely to be overweight, once weight is gained it’s difficult to lose and they are more likely to be 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 and decrease the risk of cancer in adulthood.
