An American software engineer has created 'Soylent,' a drink that he believes provides all the nutrition a human needs to survive. Using easily-obtainable ingredients, Rob Rhinehart makes the beverage almost every day, replacing his regular meals with the all-in-one solution. Rhinehart breaks down the ingredient list in a blog post, but doesn't list the exact instructions to make his brew as he's not "fully convinced of the diet's safety for a physiology different than mine." You can read a full interview with Rhinehart over at Vice, or follow his Mostly Harmless blog for regular updates on his experiment.
