Theory

My new theory--and I have not researched this so someone has probably already looked into it--is that this craving weird foods thing is to get a wider variety of nutrients than usual.

I know I tend to mono-eat. And it seems that the foods I find popping into my head at random times (frozen corn with butter, my mother's stir-fry) are things I have not eaten in a while. (In some cases a 20-year-while.)

I still want the things I normally, eat, too. Just with additions.
