When you say free fruits and vegetables, does that mean that we've already eliminated from all of the schools all of the candy and pop machines?
The problem is, when you're given a choice, it's like saying this is good for you, take it. You tend to grab things that you desire more, and if the option is still available to these children, by having those machines readily available, they will opt for them, even though the fruits and vegetables are free.
Having said that, of course, it is mainly in the higher socio-economic groups. Those, perhaps, in the lower socio-economic group may be more apt to and, finally, be eating the right types.... I think that's still a good idea, but I think it has to go hand in hand--
