They just bundle the known "essentials" for actual survival (plus carbs), based on the current status quo medical majority opinion. However, thrival (the next strival after survival ;) is more subjective and much less well-studied in terms of: micro-nutrients, co-enzymes, certain protein-chain configurations, preformed vs substitute-for-own-conversion fat-soluble vitamins (DAKE) or ascorbate, etc. Another "complete food that you can drink" would be raw eggs, but in this age and place, that idea freaks folks out a lot more whereas such soy concoctions don't in the least. So, go for it ;)
