Gollum...lembas?

[The Only Real Estel]

But the aversion wasn't meaningless! Gollum is supposed to be this creature that while once good is now intrinsically evil. As elves are meant to be like the embodiment of all things good then Gollum being unable to touch things made by them would actually be a good way to show his nature.

That's true, but the aversion is not needed to further the plot, perhaps I should've put it that way.

This seems perhaps a small change, but it annoys me because it shows such a different attitude! In the movie Frodo shows contempt and disgust of Gollum ("Don't touch me!") but Book- Frodo showed pity and the real wish to help Gollum:

Movie Frodo is certainly different from book Frodo in many ways, & you pointing out the lembas sequence is one that I really hadn't noticed before. Although Frodo treats Gollum with enough pity at times ("I want to help him Sam."), he seems to have mood swings on the issue. Although I think the "Don't touch me" was perhaps directed to Gollum more out of fear of him touching his Ring than anything.
