Re: flatulence, I found that the Rosa Labs version (capital S Soylent) does that way worse than many of the DIY versions. I'm sure that some of the other commercial soylents are similarly not as bad for flatulence. I currently make:

It accounts for 50-100% of my calories depending on the day. Fairly inexpensive, good nutrition, and very scalable for different calorie needs. Most importantly no farts.
