A potentially relevant data point that doesn't often come up in this discussion is the evidence produced from housecleaning. As a housecleaner I deal with all kinds of materials including pee, poop, and puke from people and their animals and other stuff like used machine oil from engines and physical things like sand and pine needles. By far the absolute worst is residue from cooking with seed oils. There are many special products out for dealing with this because simply scrubbing with hot water and concentrated soap is often not enough. The residues are most similar to glue or shellac. If a substance like heated seed oil generates material that is among the greatest challenges a housecleaner can encounter then how is ingesting it okay?
