Given that dogfood and catfood work as far as mono-diets go, I'm pretty hopeful that personfood is going to work out as well. I don't know enough about nutrition in general to identify any deficiencies (and you kind of have to wait 10+ years for any long-term effects), but the odds are good that it or something like it will work out in the long run. I'd go with really rough priors and say 65% safe (85% if you're willing to have a minor nutritional deficiency), up to 95% three years from now. These numbers go up with FDA approval.
I actually thought this way at first, but after reading up more on nutrition, I'm slightly skeptical that soylent would work as a mono-diet. For instance, fruits have been suggested to contain chemical complexes that assist in absorption of vitamins. These chemical complexes may not exist in soylent. In addition, there hasn't really been any long-term study of the toxic effects of soylent. Almost all the ingredients are the result of nontrivial chemical processing, and you inevitably get some impurities. Even if your ingredient is 99.99% pure, that 0.01% i...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
