But that's useless unless it's a large, controlled, randomised, double blind, trial.

So far we have people selling stuff telling us "it's okay".

I'd be really interested to see what the FDA has to say about Soylent. Have any of the Soylent team got legal advice?

It's not useless. It will shake out any number of "obvious" problems.

It is just not sufficient to deem the product generally safe as a food substitute for everyone and/or for prolonged use.

For me at least it would not be useless, because soylent wold be 10x better food than what I eat now.
