this review of the new product Soylent -- a (supposedly) nutritionally complete powder that costs about $3 per serving and saves all the muss, fuss and bother of preparing and eating food.
The review does not say why to inventors chose the name "Soylent" since the sci-fi flick "Soylent Green" was pretty grisly. Whatever the reasons, I suspect the inventors are onto something in a time when things sag to ever-more-impoverished depths.
The central criticism of Soylent is that it is uninteresting and bland and can cause some (possibly temporary) stomach upset.
As a sole nutrient, it sounds bland. Perhaps on a mix-and-mingle basis, it will come into use. The military or prisons might like it.
