The ring of slow digestion is a ring that appears in NetHack.
When worn, the ring nullifies the ordinary consumption of one nutrition per turn. Nutrition consumption from all other sources, including the ring hunger from the ring itself, is unaffected; in practice, this means that a non-spellcasting player can go without being hungry twenty times longer than normal. Wearing two rings does not cause the effect to stack.
With two rings of slow digestion, and good technique, the player can go indefinitely long without losing any nutrition, because the ring hunger for each hand is calculated on different turns. Normally, this is counterproductive due to the higher nutrition consumption from multiple rings, since the effect does not stack; however, ring hunger for your left hand is calculated turn 4 (mod 20), while right hand hunger is calculated on turn 12 (mod 20). The idea is to wear both rings, but removing one of the rings for the turn that its hunger is calculated. No known ascensions have made use of this trick alone to ascend with the foodless conduct intact.
The ring of slow digestion is somewhat difficult to informally identify. Dropping it into a sink does not consume the ring, and produces a message about the ring being "regurgitated", and you can them name it in a prompt. The ring can also be formally identified by testing for it while inside a digesting monster, as indicated above.
You can identify a ring of slow digestion by its nutrition-cancelling property, though the process is complicated slightly if you are extensively testing rings. As soon as your nutrition level crosses a visible threshold (i.e. the display no longer shows you as Satiated or you become hungry, put on the (ideally noncursed) ring being tested and eat something that provides low nutrition, such as a fortune cookie (with a nutrition of 40). If you go a long time (e.g. as many as 800 turns for a fortune cookie) without recrossing that boundary, the ring is probably slow digestion.
