> Obesity rates have tripled in 3 decades, I don't think we can blame Soylent for that, but clearly something major has gone terribly wrong with the industrial food system
We can blame the paint industry and the cotton industry for the food industry's mistakes. Paints & stains used to be made from "drying oils" (soybean oil, linseed oil, etc), now they're made from petroleum. Cotton production creates a lot of cotton seed as a waste product.

Instead of going quietly into the night, the seed oil industry now sells "vegetable oil" for human consumption. Crisco was made from hydrogenated cottonseed oil until it was reformulated in 2007. IMHO, Crisco is still not appropriate for human consumption.
