Step-by-step explanation:
One example of a campaign that the Public Health England (PHE) has set up is the 'Change4Life' initiative. This national campaign aims to help families make healthier choices and prevent childhood obesity by providing information on nutrition and activity guidelines. Through various resources such as easy recipes, fun activities, and educational materials, the campaign encourages families to reduce sugar intake, eat more fruits and vegetables, and engage in regular physical activity. Another notable campaign is 'Stoptober', a movement that supports smokers across England to quit smoking during October, providing a range of free resources including an app, daily emails, Messenger bot, and online communities.
