Isn't it a possibility that a low-carb solution to milk could be cheese? And as for whole grains, what kind are they talking about? I honestly don't know anyone who eats 'whole' grains! Every teen I know (with the exception of mine) eat bread by the gobs, but it's the processed junky stuff. My kids eat low-carb bread, which has more fiber and under-processed grains in it. I also haven't seen one vitamin or mineral that's available in grains that isn't available much more abundantly in vegetables, berries and nuts.

My kids eat way more healthily following a low-carb plan than they ever did before, and to them it's a way of life, not a 'diet'.
