1) Something always glossed over in the PR is we've been feeding "sick" people nutritionally complete liquids out of a can for decades with no real problem. Baby formula, and old people and cancer patients drinking Ensure and the like. Its really old stuff and heavily studied. What is new, is marketing it to people who are more or less healthy (as healthy as you can be on the standard American diet of junk food, anyway). I've tried left over cans of ensure. Personally not my cup of tea. Like a melted mcdonalds shake, kind of. Also tried baby formula, not impressed, like super heavy cream, sorta. This previous experimentation does not encourage me to try soylent. 2) Like it or not, admit it or not, we're mammals just like livestock or pets. It seems that feeding housepets scientifically designed food, every day, for decades, really does boost their lifespan compared to a diet of mice and bugs in the wilderness. This gets the anti-evolutionary people all found up, the mere suggestion that us people are animals too or that their god didn't create us separately from the animals ... Also if you talk to a livestock rearing farmer about what he feeds his hogs / cows / whatevers to fatten them up for slaughter, and then compare what he fattens his livestock with, to the ingredients on the food aisles at walmart, and then look at how round the shoppers are, I'm just saying you won't be too surprised. You can dislike it all you want, but we are mammals.
