Generate text that refutes this claim: Targeting schools will be an ineffective strategy.  Schools may seem like a perfect place to effect behavioral change in youth, since 95% of young people are enrolled in schools. [1]  But what researchers find is that changing the choices we have available does not necessarily lead to any behavioral change. Penny Gordon-Larsen, one of the researchers, wrote: "Our findings suggest that no single approach, such as just having access to fresh fruits and veggies, might be effective in changing the way people eat. We really need to look at numerous ways of changing diet behaviors. There are likely more effective ways to influence what people eat.” [2]  In the case of school children is this point seems particularly salient. Given that high school students in the US average only 6 hours in school [3] and the widespread availability of fast and other forms of “junk food”, we can hardly expect that impacting this single environment of the school will lead to any lasting behavioral changes. Realistically, what we can expect is for school children to go outside the school to find their favorite snacks and dishes.  Even if, by some miracle, the ban would change the behavior of children in schools, there is still the matter of 10 hours (the ATUS suggests kids sleep an average of 8 hours per day) they will spend outside schools, where their meal choices will not be as tailored and limited.

Even if students spend a small fraction of their time in schools – and 6 hours is by no means an insignificant amount of time – it is still an incredible opportunity for intervention for a very important reason.  The reason is the incredible potential for homogeneity of experience. at least in the aspect of food offered. We are able, to certain extent, control the school environment in such a way as to promote healthy choices and eliminate bad ones. When students return to their homes, we have lost that opportunity. In a nutshell, one healthy meal per day is much better than none.  It can also be contended that children often share experiences from school with their parents and siblings back home. Thus a healthy environment in school could, potentially, find its way into homes we couldn’t otherwise reach by any other means.
