I’ve made a USDA-based generic nutrient profile: http://diy.soylent.me/nutrient-profiles/532264deb6648102005bd6e1
The details are in the notes, but basically a Soylent that fits this profile should fit the USDA recommendations for most people ages 19-70, regardless of gender or activity level, except that women over 50 may need to add a calcium supplement. Of course, people with different activity levels would consume different amounts.
I made this partly because I see a fair number of recipes that seem to be intended for general use, and I figured it might be useful to have a better profile for such recipes.
The main downside is that all of the nutrient windows are narrower than in a non-generic profile.
The Google Drive spreadsheet with my calculations is linked in the profile notes.
