None that I would recommend. None of my criticisms are original, Soylent still seems a very haphazard concoction to me. I do have a bunch of specific issues with Soylent that I haven't discussed in detail e.g. lack of cholesterol and saturated fat not being great for hormones. But yeah, I'm not super motivated to get deep into it unless I decide to try to turn the latest variant of Soylent Orange into an actual service. I'm still working on it.
