Even leaving "detoxification" question alone:
Fact #1: Soybean lechitin (the stuff added in pretty much every item with longer shelf life here in US and which makes lives of folks allergic to soy so crazy difficult) contain "essential phospholipids" (phosphatydilcholine being most abundant, 13% dry mass)
About Soy Phospholipids
Fact #2: Phospholipids like that one are the main component of cellular membranes (read any good physilology book)
Now, if you get any amount of this stuff directly in blood, presuming it can just go there and build itself into somehow "injured" cell membranes (which is physically impossible - entropy law is still there, but let's forget about this for a sec), what is the probability of it getting right into liver and nowhere else, accounting for the fact that we all have kilos of the said membranes?
Zero. Nope. impossible, period, according to laws if physical statistics.
And, if someone still searches for evidence, please keep in mind that the order of getting it in Eastern Europe is sometimes mirrored from what we have in developed world. Here we do research and see what comes out of it. There, they got ideas and do research the way so that they are confirmed or disproved.
