I've had the same thought -- the history of the last 100 years of processed foods definitely supports the "don't know what we don't know" suspicion. One hidden assumption behind Soylent immediately jumps out at me: the assumption that it is healthy to ingest the same level of every nutrient constantly over time. In reality it's possible that our bodies are actually adapted to -- and benefit from -- variation in nutrient intake. We are not engineered industrial artifacts designed to run on constant engineered inputs. We are the product of a varied, highly textured environment and an evolutionary design process whose "reasoning" is quite alien from our own.
