Any bored nutritionists out there? I've put together a list of nutrients, with their USDA recommended quantities/amounts, and scoured amazon for the best deals, in trying to create my own version of Soylent. My search was complicated by the following goals:

• I want my Soylent to have all USDA recommendations for a person of my age/sex/mass.
• I want my Soylent to be easy to make (which means a preference for liquid and powder versions of nutrients).
• My Soylent should be as cheap, per day, as possible (I'd rather have 10 lbs of Vitamin C at $0.00/day than 1lb at $0.01/day).
• Because I'd like it to be trivially easy to possess a year's supply of Soylent, should I find this to be a good experiment.
• I want to make it easy for other people to follow my steps, and criticize my mistakes, because I'm totally NOT a nutritionist, but I'm awfully tired of being told that I need X amount of Y in my diet, without citations or actionable suggestions (and it is way easier to count calories with whey protein than at a restaurant).
• I want the items to be available to anybody in the USA, because I live at the end of a pretty long supply chain, and can't find all this stuff locally.
• I'm trying not to order things from merchants who practice woo-woo, but if they have the best version of what I need, I won't be too picky.

There's probably other things, but I can't think of them at the moment.

The spreadsheet isn't done yet. I hope to make it possible to try dynamic combinations of multiple nutrients, since most merchants seem to prefer the multivitamin approach. Plus, I'd like for there to be more options for liquid and powder substances, because they are easier to combine. Right now, I'm just an explorer, but eventually I'd like to just have a recipe.

If this all sounds too risky, I've also made contact with Rob, and he says that he's planning on releasing his data in a few weeks, once he's comfortable with his results (I think he's waiting on friends to confirm his findings). I'm planning on showing him my list, so we can compare notes. It has already been noted that his current Soylent formula is a bit lacking in fiber. My Soylent is currently slated to use psyllium husks to make up the difference, but I'm looking into other options.

A brief overview of the options indicates that this isn't much cheaper than other food choices (~$7.20 / day), but it meets all of your needs, and once the routine is down, would be fast and easy to make, and could be stored for a long time. So I'm optimistic.
