As someone with Crohns disease, who has been on an elemental diet not by choice but by necessity, I can assure you it is very much a real world effect. Unfortunately, we lack a corpus of evidence of long term liquid diet feedings (and intestinal investigations), mainly for ethical reasons, but there is at least one good rat study I could quickly recall: http://link.springer.com/article/10.1007/BF01308310 http://link.springer.com/article/10.1007/BF01308310 There are, however, countless great articles I suggest you read on liquid diets and their impact on satiety and other important illness recovery markers. One of the important topics for researchers has been how to safely transition patients more quickly to solid food, given some of the less desirable side effects of the liquid food diet. And yes, I understand that the Soylent team is confident that they've solved, for example, all gastric emptying issues by adding exogenous fibres. I'm positing that for every variable they're convinced they've figured out, they're opening up another potential set of problems that they've not even considered. Their latest opacity on this recall isn't giving me hope that I'm wrong here.
