Abbott and Nestle and other companies only offer replacements meant for 90%+ diet use for people under medical supervision. I don't think we totally know how to create a reliable replacement without missing something - and everyone's needs are different - so until someone figures out how to solve that problem it's not going to exist in a form you can buy off supermarket shelves. The idea of drinking Ensure for 90% of my meals scares me for the same reason Soylent does. The unknowns are too much - small startup or major pharmaceutical company alike.
