I realize that this subject was brought up before, and the thread was totally jacked (as many are here), but this company seriously has a powder product that, when mixed with oil and water, is supposed to provide all your nutritional needs. I couldn't find the stats, but I heard an interview on NPR with the founder, and he claimed that the powder would last for years if properly stored. Think powdered "Ensure" or similar. This could be something for a SHTF scenario, depending on how well it stores and if it has the nutritional properties that it claims. Anyone know anything about it? (Other than "IT'S PEOPLE!!!!," or some Charlton Heston joke.)
