As I say in this post, the difference is that Soylent isn't created by manipulating existing food but 'from scratch'. While it's not the first food to be created in a lab, it is definitely the most ambitious. No, that doesn't make logical sense. I know McDonald's is unhealthy, but I might be eating worse than that for all you know. Besides, I don't say that. Unhealthy is not exactly what I was going for - I was thinking more about long-term dangers of mixing a really diverse set of nutrients and vitamins. Let me phrase it another way - that which makes Soylent unique and healthy (its all-encompassing set of ingredients) is also the thing I am cautious about with my limited knowledge of chemistry and food safety.To say Soylent is somehow unhealthy implies you have a better diet.
