Wheat is only popular because it has been a starvation food for the Europeans for thousands of years. If you are not starving, there is little reason to eat it.

Wheat is only popular because it has been a starvation food for the Europeans for thousands of years. If you are not starving, there is little reason to eat it. The wheat seed has evolved complex phytotoxins as defense to protect itself from being eaten. We try to get rid of a lot of it using yeast and bacterial fermentation and cooking, but residue is enough to poison people to varying degrees. There are grains which are less toxic. Having said that, we may need to preserve a subculture to keep the practice if we ever need it (just for diversification purposes, in case we lose other grains to disease or change in climate).
