Yeah it's always tough challenging every preconception society has created in us - I of course am not immune to that by any means. Whilst I can imagine soylent is nutritionally dense and quite possibly very sound from that point of view the work of Weston Price would strongly suggest a major problem with lack of good mastication. The skull isn't as static a structure as we might believe it turns out and lack of effective nutrition AND chewing caused many problems in people (weakening of the jaw and facial muscles and subsequent narrowing of the palate and skull) according to his studies. Basically we can try and stray from the path our ancestors took but not too far too quick! Our bodies only evolve so fast so yep, even soylent probably has its downsides.
