Cancer Survivor, writing about Health and Fitness as you age

I think it is really difficult raising children in this complex society, and raising girls perhaps even more so. I know there is a lot of discussion about the images of women in the media and the unrealistic expectations of girls. This is a picture taken from a recent Latina Cosmo. While no personal attack on the model is intended, she looks emaciated to me, and for sure I would not want any of my daughters aspiring to this representation of beauty. I do however have nieces, but they don't live in the US and their exposure to this is not quite the same. Fortunately. I am not sure how parents counter this (and I am assuming they would try), or even if I should be parenting my sons differently or how. The only thing I know to do is to emphasize health and personality over looks.
