To be fair to Soylent, many of the ingredients listed are simply vitamin and mineral sources. They have scary-sounding names, but are not scary things.

I'm not convinced your alternative is actually more healthful, nor do I believe it contains the vitamins or minerals you'd need for it to act as a reasonable meal replacement. From a macro perspective at least, I don't see anything particularly wrong with Soylent's product.
