About a quarter to a third of childhood has been lost as the average age at onset of puberty has declined over the past 100 years. What has changed?
We are eating much more fat and protein and growth hormones than we did 100 years ago. Eating more in general, and eating more of these three things in particular, tends to increase growth rates.
Maybe we should be making the change in the other direction. Or maybe we should step back a bit, moderate our intake of these growth-promoting substances, and talk about whether we want to change the timing of the onset of puberty. Do we want childhood to end sooner, or later? Or does it matter one way or the other?
