I don't like to be alarmist, but some of this is a little scary, IMO. Small changes in a society can have massive impacts over generations. If you look at what happened to experiments with feeding house cats an altered diet in just a few generations. People are already eating a lot of things that wouldn't even be considered food a couple centuries ago, and maybe still shouldn't be.

We have a lot of increasing hormone production issues in western society already, I'm not sure that fiddling with things further is a real solution here without risking a lot of damage to society as a whole.
