would be controlled for in a study.

If you want to see the state of the research, there are a number of
articles
on PubMed. There are other problems with hormones in beef, besides the
precocious sexual development.





I would think a good place to do research is in a closed community like
the Amish that live off their own beef they raise.

Yeah, maybe. But they also have a lot of genetic factors to account for,
because they've been a pretty closed gene pool for a very long time.

It's not difficult to select for non-obese subjects who eat certain
quantities of commercially produced beef, or to keep separate data for that
and many other factors. It's a big enough issue that it should be worth a
study with a very large cohort. But there are no pharma interests that I
know of that would stand to make a buck off of it. That means a government
study. We won't see that for a while, if ever.
