Your claim is not backed by any evidence at all. There is nothing special or magical about "whole foods". And what is wrong with what you just mentioned is that now I need to keep fresh fruits and vegetables and milk on hand, those spoil. Your proposed meal replacement is also incredibly deficient in over half of known vitamins and essential minerals. Take my default challenge for the "oh its so easy to get all your vitamins and minerals" people: put together a recipe for me that gives me 100% of all my vitamins and minerals. When you actually try doing this, you will realize how unreasonable it is.
