Help with my debate on government regulating unhealthy foods in restaurants?

[Caitybeck]

I'm in this high school discussion and debate class and currently we are working on cross exam debates. This is the kind of debate where you get to ask your opponent questions, and vise versa. The resolve for my debate is "The government should regulate unhealthy foods in restaurants". I'm on the the negative side which does not want the government to regulate unhealthy foods in restaurants. I was curious to see if anyone had any suggestions on things to look up, such as specific cases or just simply relative information. Are there any specific questions any of you think I should be asking? Are there any kind of questions you think I should be prepared for? I just want to make sure that I have my case plan fool proof and am hoping to get an outsider's opinion. It's greatly appreciated, thanks!
