If that's the case, it boosts the argument that the Government needs to take a hard look at the impact of the marketing of unhealthy food choices.
It suggests that as the influence of parents wanes, children are more vulnerable to messages outside the home encouraging them to make unhealthy food choices.
Last year researchers found sophisticated marketing methods, such as cookies and advert-linked gaming, are being used by food websites to target children.
It stands to reason that if we want children to make healthy food choices, then we need to limit marketing that encourages them to do the exact opposite.
The consequences of letting this trend continue are frightening. A 2016 study assessing the rate of health dangers linked to obesity in young people found that 40 per cent of obese children and adolescents were at high risk of developing type 2 diabetes in future.
That's a future we want to avoid at all costs.
