A hot button topic right now involves efforts to curb child obesity by encouraging advertisers to limit the messages they send to kids about foods that are high in sodium, saturated fat, and added sugars. Under new federal rules, even the scoreboards in high school gyms will have to advertise only healthy foods. Several large cities including New York City and Philadelphia have tried to prevent the sale of large sizes of sugary drinks to fight obesity. Public health advocates hail these attempts, whereas others argue that they would transform the United States into a “Nanny State” that imposes on our freedom to choose to consume whatever we would like. Should city, state, and federal governments dictate what (legal) products people should consume, even when the population’s health is at stake?
