We've known that nutrition drives a big part of height variability for a long time now. Yet as a species we've failed to act on it, missing the opportunity to improve the health of many children. There's still time!
This makes me wonder if I had eaten better when I was young then I might have been a bit taller but really, I think it is all about genetics. Yes, eating bad can bring your body down but genetics will ensure you stay at a certain height and no more.
