I have a large pile of edible rings that I'm considering eating for their intrinsics. Problem is, I don't have a ring of slow digestion, and food has been in short supply. Most of the rings would confer a 1 nutrition drain if worn (adds up to 6). I don't want to risk starving myself for the intrinsics, but it would be nice to have some free fingers. The wiki on eating jewelry says nothing about whether the intrinsic negates he nutrition penalty, and neither does the page on intrinsics Any facts regarding this?
The standard accessory hunger (1 extra hunger every 20 turns) is assessed specifically for wearing a ring (or amulet). If you eat the ring, you're no longer wearing it, so you don't suffer this anymore.
However, conflict and regeneration (and hunger) still have an additional hunger penalty of 10 hunger every 20 turns. If you eat a ring of regeneration or conflict (bad idea BTW), you still suffer this hunger. But eating ordinary rings such as warning or increased damage only has the downside that it's only 33% likely to actually grant you the intrinsic; so make sure you have extras!
