> it's [not] safe to eat Soylent or another similar product regularly. As opposed to what? Eating organically grown vegetables and fruits, nuts, mushrooms and oceanic fish? Sure. But that is definitely not a diet of most people even in developed, rich countries. And while we can't say confidently it's safe to eat Soylent, we absolutely can claim that most human diets are really, really harmful. I bet Soylent would be much less harmful (if at all) than eating fast food, pizza with red meats fortified by antibiotics and hormones.
