I'm amazed by how FDA regulates drugs and how it regulates... actually how it doesn't regulate, supplements and things like Soylent, which is not even a supplement but claims to be food "that possesses all the essential ingredients a body needs to be healthy".
Studies anyone?
Maybe it does contain all the essential ingredients but maybe the human body can't process them effectively. Maybe it's not very healthy taking all these ingredients every day.
Maybe in the long run it'll have bad effect on the microbiome, intestinal mucosa or on million other things in the human body.
Whenever someone question those things, the answer is "But it's better than junk food". Well...
Edit: Ok, my bad, it's actually regulated as a food [1].
