I'm not a real fan of chewing food, but having done a similar diet before I prefer it. Turns out that even though me and food don't always get along, after 3 weeks on a liquid diet the cravings for real food for me come back. There are plenty of weightlifters who have done similar full-liquid diets for years before soylent, this data exists but has been largely ignored since it's from a different kind of community. Anyways - 30 days isn't enough, many items take longer to produce issues. Vitamin C comes to mind, it's destroyed by sunlight, copper (copper is good for destroying a few biological agents it seems, birth-control and Vitamin C, oh it's uses - but we need it as well so it'll be there in soylent in trace amounts), and age, but so little is needed to avoid scurvy, and it takes about 3 months from your last consumption of it to produce adverse results, that it wouldn't be an issue... in the short run.

To address your comment about animals: I saw animals that are littered with disease standing above the product. Standing, breathing without masks, talking without masks(which means trace amounts of spit), in standard clothes that've probably been exposed to much. The rat was far less disturbing than seeing the people who were handling the product.

Contrary to the blood-work, there is a issue that presented itself after 30 days. Not a nutrient deficiency, but a chewing one: he mentioned he started chewing gum due to his jaw aching. As far as I know chewing is supposed to help keep the jaw healthy (an expert/dentist has been sorely lacking from these soylent discussions, I imagine they'd have much to say about chewing, jaw, and tooth issues that crop up), and as someone who hasn't done a great job of that in life... I certainly wouldn't want to mess with jaw health anymore.

Yeah, I was pretty appalled to see one of the founders/employees measuring ingredients out of a box on the floor while wearing dirty espadrilles (canvas shoes). I suspect that if you look at the skepticism/support in this thread you'd see a strong correlation between people who have worked in food service at some time in their lives and those who haven't.

Name one competitive weightlifter, powerlifter or bodybuilder that lived primarily on a shake made from powder for years.

As in people doing these diets years before soylent, not years on said diet. My grammar might not've been clear enough.

EDIT: Specifically I'm thinking of the hundreds (if not thousands by now) of people on T-Nation/Testosterone Nation who've done the 1-month Velocity diet, which is (or was, I haven't been there in years, but that particular diet has been around for at least 5 years+), a protein shake diet with very little solid food. There are years of people doing it for a month and relating their experiences, highlights and downfalls, and I'm sure there are several more experiences in that world that would provide better data points. However, it has the issue of being mostly anecdotal evidence.
