There’s some new research that highlights how we each have different nutritional needs, and what is beneficial to some may not be beneficial to others.
Which makes me want an ambient, customized soylent maker even more:

Since before Soylent, I’ve envisioned a system that could ambiently, or with extremely minimal effort, assess an individual’s current needs (e.g., http://news.bbc.co.uk/2/hi/health/1433904.stm , http://www.halfbakery.com/idea/doctor_20toilet). Soylent gave me hope than not only would we be able to ambiently assess, but we could use that assessment to create up-to-the-minute custom prescriptions. I think something like your Soylent GA in combination with http://discourse.soylent.me/t/soylent-vending-machine/497 and some type of data recording device (e.g., to keep track of things like recently prescribed soylent meals, recent assessments, preferences) would provide the dynamic formulations.
In other words, I could wake up and take a leak. My in-house diagnostic toilet would send my phone my pre-breakfast assessment while I make my way to the kitchen. Once in the kitchen my in-house soylent machine would ask if I want a latte, berry, or other flavored soylent, and based on my option and pre-breakfast assessment it would prepare my up-to-the-minute customized soylent formula and send that formula to my phone. This would repeat over the course of the day, with each subsequent meal taking into account not just recent assessments, but also all the previous meals of the day.
Over the course of days, months, and years, my personal formula would evolve to match not just my obvious needs (e.g., sodium within DRI) but also my personalized needs (e.g., my assessments consistently show that I maintain higher than average sodium levels, so my personal formulas move into the lower quartile of the DRI).
In theory, other assessment sources (e.g. dna, blood pressure cuffs, blood draws) or prescription sources could be factored into the dynamic soylent formula. For example, after a traumatic accident a surgeon could prescribe a lower caloric level along with pain killer. (Albeit the latter would make it more difficult to use public Soylent machines. Even then something like a powdered version of the prescription could be blister-packed and used in soylent machines.)
