Not get caught up in the hate/arguing, but if they're raising money for this, and will be apparently working within the FDA guidelines, wouldn't they have strenuous testing before they release this to market?
edit: I will probably try it myself as a replacement for some meals, so I hate to simply sound like another voice piling on, but it seems pretty clear to me (whether it was intentional or not) that the "FDA-approved" comment is misleading.
