Our bodies, ourselves...I don't think we'll ever learn

I am now, and have been for many years, intensely fascinated with the concept of body image, most particularly as it relates to woman, and most specifically (though not exclusively) to American women.
A review of the body image of the American woman reveals a number of interesting characteristics. The roaring twenties brought with it the flapper, a fashion style that played on the roundness of a woman's figure, while also disguising it's more ample areas. As the decades passed, the prepubescent "boy body" has become prevalent in the American standard of beauty. We strive to be thinner; the figure that Twiggy debuted to us in the sixties, of lean, angular limbs, boyish angles and no breasts, took hold. Already, American women had begun to worry about their figures, worry about the roundness of their hips and the curve of their stomachs. Where once the Rubenesque figure spoke of money and breeding, it quickly lost ground in a country over run with prosperity and good fortune. So, time flows by, and women try more and more to repress those things that make them female. The caloric intake recommended by modern diets is the equivalent of the caloric intake maintained at Nazi prison camps as "starvation rations"; what can this say about us, except that we as females are only as good as the number of bones that can be glimpsed beneath our skin, the flatness of our breast, the lack of hip or butt, the very features that once identified us as female and beautiful?
I mention all this because we have become a culture of repression. Yet by the same standard, I really wonder what the next generations of women will strive to achieve. For years now, science has been reporting that girls are entering puberty earlier and earlier. They are showing first and secondary sex characteristics at much earlier ages that even my generation. As a result, their baby fat spills almost immediately into more mature lines and curves. An article in Double X ezine (http://www.doublex.com/section/health-science/younger-girls-bigger-breasts-are-chemicals-blame) makes me wonder if nature is not having a laugh on all of us. That which we are struggling so hard against is now happening beyond our control. For our own bodies, we can botox, stretch, and remold almost anything we want, but not so for our daughters. What's frightening to me is to wonder if this won't mean that the plastic surgery that is becoming so common place will just start at an earlier age, or will this earlier entrance into womanhood make us step back and embrace the bodies we are meant to have? It's disturbing to think that this earlier puberty may be caused by the hormones and chemicals that are everpresent in our food supply, but maybe it will force our hand. Perhaps, instead of lip service to healthier bodies, we will once again see curves as beautiful.
