Nikki, First off if you label a food as 'taboo' it will immediately become desired.  I can have all foods I must only have allowances made for them, If I wanted a doughnut I could have one, I would just need to make adjustments for it.  In most cases, it is just easier to pass it by than to do the math and change my routine for it.  At her age she is going to rebel against any thing you say, and the harder you push, the harder she will push back,  it is not you or her, it is a stage of maturing.  It is in my opinion better to make the info available, don't even mention it, but in a place she will discover it, she is more likely to pick it up and read it that way, and if she decides that this is what she wants  she will do it and as it is her choice she will do it well.  I am not a councilor or anything, I just had 3 kids so it's a been there-done that-didn't even get the tee shirt.
