Soylent 2.0 has had more than the daily maximum safe amount of soy in a single meal from the beginning. And according to the Soylent FAQ, Soylent powder already contained 53mg of soy/isoflavones per serving [1].
This blog post, and my reply, was about the powder. 1.6 introduces soy as a major component for the first time, which is what I was trying to say earlier.
Edit: to clarify, 2.0 is a prepared soy-protein-based drink which, until now, had a very different formulation from the 1.x powder product.
