Should schools / government agencies be regulating our lunches?

 Should schools / government agencies be regulating our lunches? I am here here to explain what this is and the pros and cons.
 A  regulated lunch is when a school ban a certain type of food. This means that when a child i seen eating that food, it will be confiscated. The school cafeteria is also banned for selling that particular food. 
By doing this, people are hoping to get kids to eat healthier food. 
 A pro of this idea is that kid would obviously benefit from this. Many parents are very busy in the morning so they usually throw anything edible at hand into their children's lunches. Usually stuff like candy and chips. There was one little girl whose lunch was exactly that! 
 But a negative result might also happen. This setup is almost like a prison in a way. Students may want to rebel and go outside to eat instead. The government would not like that and probably wabt those restaurants to change.The students may also think that "Eating healthy foods will keep them healthy, why is exercise needed?" If these kids stop exercising, this will be one of the factors that will cause them to go obese. 
 In conclusion, I think that the school regulations should not be allowed. I think that it really is the families that should support kids to eat healthy by something as simple as a praise or a reward for the kid when they eat healthy foods. If kids enjoy eating healthy, this regulation is not really needed. But nobody is perfect, and it is completely normal to eat treat yourselves to eating hamburgers once in a while.
