It's Soylent - literally
Maybe not made of humans, but for humans.
Soy has some VERY detrimental long term repercussions for men in particular, but at most of our ages, phyto-oestrogens aren't a major problem For young men though, yes they are, and research is showing a stark feminisation of Asian men over the decades. It's not pseudo-science, it's a genuine problem (lower birth rates etc).
