I was going to give Soylent 2.0 an “F,” but it has not killed anyone yet, so I bumped it up to a “D-.” It contains potentially harmful ingredients; it is nutritionally inadequate, it is bad for your gut, and it tastes like glue. The only advantage it has is speed, but there are other products on the market that are just as fast and are about the same quality. If I were stranded on a desert island, I would drink Soylent 2.0 to stay alive. Other than that, I have no use for it.
This post succinctly sums up most of my issues with the Soylent phenom. John and Jason are both health and nutrition extraordinaires, and they did an excellent job of objectively tearing the drink apart.
