I found this new diet-replacement powder called Soylent the other day. It has everything you need to thrive and is better than probably 95% of your blades' diets. It has all your macro nutrients, probiotics, protein, etc. that you need to be healthy. The creator has been on this stuff for over 3 months and he feels better than ever. There is also positive anecdotal evidence from testers and they will soon be doing clinical testing once their crowd funding campaign is over. http://soylent.me is the site.
