I don't know either, but I strongly, strongly suspect the laws of thermodynamics are more important than the nuances of human biology, such as they may be. Human biology has done exceedingly well in ridiculously varying conditions. I really doubt that a long lasting lack of X nutrient is going to kill someone. The defining characteristic of human biology is that we live despite tons of variations in diet, activity level, and exogenous conditions like water purity, temperature, humidity, etc. The human body is damn good at figuring out what to do with an incredibly diverse array of energy sources. It is not fragile AT ALL. But again, my beef with Soylent is that they make wild claims that might not be accurate. And so what, really? Every other supplement manufacturer does the same damn thing - and worse. See also: Any "growth hormone" supplement, deer antler spray, etc.
