I dislike the highly compressed ration pill idea large because I feel it'd just pass through a normal person without really being absorbed. Getting that much material condensed down to a small pill would make it dense as a rock.
Soylent, like
Mana, also aren't really marketed at the poor or refugees. It is more of a health-conscious thing or like they said 'food replacement'
Now if you're in an emergency, have refugees, or are dealing with the really destitute you're gonna want some
Plumpy Nut. Now we're talking about
therapeutic foods for emergency situations and not just healthy food replacements.
But what are the differences between a food replacement like Soylent and a therapeutic food like Plumpy nut? The Therapeutic food is ready to eat out of the package, contains a lot more energy, and is easy to manufacture. As a refugee you may not have a lot of water, containers to prepare food, and you may not know where your next meal is coming from so you're gonna want your Pumpy Nuts over your Soylents.

A few years back Yamatai was having a food crisis, and Wazu's solution was
Calorie Paste.
This is a Gartagen version of Plumpy Nut, and could be made easily in massive quantities through triggering algae blooms and then harvesting the biomass for processing.
