Comestibles are listed above by category, then by increasing nutrition.
Japanese names of items are listed in parenthesis ().  The COST field
denotes the base price of each item.  WGT specifies the weight (100
zorkmids weighs 1).  The existance of some items depends on options
chosen when the program was compiled; they are noted with an asterisk
(*).

Food comprises 20% of all randomly-generated items in the main dungeon,
15% in containers, 22% in Roguelike bones piles, and 16% in hell.  PROB
is the relative probability of each subtype.  Eggs not laid by you have
a roughly 1/3 probability of hatching.  Tins are 1/6 spinach and are 5%
blessed, 90% uncursed, and 5% cursed.  All other comestibles will be
generated uncursed.

The nutrition of each item is listed under NUTR.  The cost of all items
are based on the nutrition by the formula COST = (NUTR / 20) +5, with
fractions rounded off.  Note that several prevously archived spoilers
did not correctly round their costs.  The ratio of nutrition to weight
is listed in the NUTR/WGT column; lembas wafers have the best ratio.
The amount of time needed to completely eat an item is given under TIME.


Hunger and nutrition
~~~~~~~~~~~~~~~~~~~~
(Adapted from the spoiler "food" by Bryan Butler
<butler@cluster.gps.caltech.edu> and J. Ali Harlow <ali@avrc.city.ac.uk>.)

Each of the following conditions is checked on the turns shown; if it is
the case, then you lose one more point of nutrition that turn.  Rings
and amulets cause additional hunger as shown; the only exception is a
ring that can be charged but is at +0.  You can therefore consume a
maximum of 64 nutrition in 20 turns (if all of these conditions were met).
  HOW OFTEN      CAUSE
  ~~~~~~~~~~~~~  ~~~~~
  Each turn      Ordinary food consumption, if carnivorous or herbivorous.
                 When asleep, only about 10% as much is needed.
  Odd turns      Regeneration from anything other than an artifact.
  Odd turns      Encumberance is stressed or worse.
  Even turns     Hunger intrinsic (e.g., from a ring).
  Even turns     Conflict from anything other than an artifact.
  Turn 4 of 20   Ring worn on left hand (except a +0 ring).
  Turn 8 of 20   Amulet worn.
  Turn 12 of 20  Ring worn on right hand (except a +0 ring).
  Turn 16 of 20  Carrying the Amulet of Yendor.

Naturally, eating some food will make you gain the amount of nutrition
in the food.  Your level of nutrition is described as follows:
  2000 or more        Death from choking (under certain circumstances)
  1000 or more        Satiated
   150 to  999        Not hungry
    50 to  149        Hungry
     0 to   49        Weak
  Below zero          Fainting
  Below -200 - 2*Con  Death from starvation


Corpses
~~~~~~~
(Adapted from the spoiler "corpses", by Boudewijn Wayers
<kroisos@win.tue.nl> and Peter Snelling <snelling@bnr.ca>.)

When a monster is killed, the probability of leaving a corpse depends on
several factors:
  PROB  CONDITIONS
  ~~~~  ~~~~~~~~~~
    0%  Killed by digestion or disintegration.
    0%  Killed by stoning (creates a statue instead).
    0%  Corpses are never generated on the Roguelike level.
    0%  Golems leave objects instead of a corpse.
    0%  Some monsters never leave a corpse (e.g., Vlad, liches).
  100%  Lizards, monsters of large size or bigger.
  100%  The Riders and Roguelike players on the Astral Plane.
   1/2  Infrequent monster that is not tiny
   1/3  Monster appears frequently or is tiny (but not both).
   1/4  Monster both appears frequently and is tiny.
There is a further reduction of the above chances for undead creatures
that die on a graveyard level: by 1/9 if it was killed by you or by
1/3 if it was not killed by you (e.g., by a trap or another monster).  
This means that wraiths have a better chance of leaving a corpse if you
lead them to a stairway and let them follow you to a non-graveyard
level, a technique called "wraith luring."

The nutrition, weight, and time needed to eat corpses is determined by
the type of monster.  The blessed/cursed status of food adjusts how
fast it becomes spoiled.  Spoiled corpses do not provide either
nutrition or intrinsics.

(Quoted from a spoiler by Sascha Wostmann <wostmann@geocities.com>.)

You can acquire useful intrinsics by eating certain corpses or tins.
The blessed/cursed status does *not* change the likelihood of getting
an intrinsic.  If the monster has more than one conferrable intrinsic,
one is randomly picked, with equal probability among all possible.
The CHANCE that the picked intrinsic is conferred varies among the
different intrinsics; some are based on the level of the monster (LEV).
If you get the intrinsic, you will get a MESSAGE (the second one if
you are hallucinating).
  INTRINSIC          CHANCE  MESSAGE
  ~~~~~~~~~~~~~~~~~  ~~~~~~  ~~~~~~~
  Fire resistance    LEV/15  "You feel a momentary chill."
                             "You be chillin'."
  Sleep resistance   LEV/15  "You feel wide awake"
  Cold resistance    LEV/15  "You feel full of hot air"
  Disintegration     LEV/15  "You feel very firm."
    resistance               "You feel totally together, man."
  Shock resistance   LEV/15  "Your health currently feels amplified!"
                             "You feel grounded in reality."
  Poison resistance  LEV/15  "You feel healthy."
                             Note: 25% better chance if killer bee or
                             scorpion.
  Teleport           LEV/10  "You feel very jumpy."
                             "You feel diffuse."
  Teleport control   LEV/12  "You feel in control of yourself."
                             "You feel centered in your personal space."
  Telepathy           100%   "You feel a strange mental acuity."
                             "You feel in touch with the cosmos."
        
Some corpses or tins have additional effects:
  :b If you eat a lizard or any acidic monster, a possible stoning
     process is stopped.
     "You feel limber" (non-hallucinating)
     "What a pity - you just ruined a future piece of art!"
       (hallucinating with charisma <= 15)
     "What a pity - you just ruined a future piece of fine art!"
       (hallucinating with charisma > 15)

  :  Eating a lizard has the supplemental effect of removing an additional
     turn of confusion and stunning.

  :  Eating a chameleon makes you polymorph once.

  h  a mind flayer has a 50% chance of increasing your INT by one.
     Otherwise, it confers telepathy.

  m  Eating a mimic makes you mimic a pile of gold for some turns. The
     larger the mimic the longer you imitate. During this time, you are
     shown as a $-sign.  If you are attacked, you revert to your normal
     form.

  yB Eating a bat will make you stunned for 30 (more) turns, or 60 (more)
     turns for a giant bat.  In theory, this also holds for yellow lights
     (but they don't leave corpses in recent versions).

  FU If the monster hat a stun or halucination attack or is a violet
     fungus, you get hallucination for (another) 200 turns.

  H  Eating a giant, stone giant, hill giant, fire giant, or frost giant
     will increase your strength.  If you had less than 18 strength,
     then you have a 19/24 chance of gaining one point, or a 1/24 chance
     each of gaining 2 to 6 points.  If you had 18 strength or more,
     then you gain 1 to 10 points (equally likely), up to 18/**.

  I  When you eat a stalker's corpse and you are not invisible, you'll
     become invisible for 50 to 149 turns. If you're already invisible,
     you become permanently invisible and get the "see invisible"
     intrinsic.  In both cases, you are stunned for 60 (more) turns.

  Q  A quantum mechanic's corpse makes you toggle your speed.  If you
     were not currently fast, you'll get fast; otherwise, you lose the
     speed.

  W  Eating a Wraith's corpse lets you gain a level.

  df If you eat any of little dog, dog, large dog, kitten, housecat, or
     large cat, you'll get the intrinsic "aggravate monster".
     "You feel that eating the <monster> was a bad idea."

  c@ If you eat a cockatrice or Medusa's corpse and you are neither
     stoning resistant (i.e. polymorphed into a cockatrice, lizard, or
     acidic monster) nor you are polymorphed into a golem, you'll be
     instantly killed by stoning.

  @K Eating something of your own species (elf if you are an elf or a
     human creature [includes Kops] otherwise) is cannibalism.  You get
     the intrinsic "aggravate monster" and lose 2 to 5 luck.

  @  Eating a were-creature makes you lycantrope of the same kind and is
     cannibalism if you aren't an elf.

  @  Eating a nurse heals you up to max hitpoints and is cannibalism if
     you aren't an elf.

  &  Eating Death, Pestilence or Famine is instantly fatal.


Tins
~~~~
(Quoted from a spoiler by Sascha Wostmann <wostmann@geocities.com>.)

You get up to 50 moves to open a tin; otherwise, you give up. If you are
wielding a tin opener, it takes one turn; any dagger or crysknife, 3
turns; or a pick-axe or axe, 6 turns.  Blessed tins "open like magic" in
one turn.  Cursed tins have a 1/8 chance of exploding and will always
contain rotten food, so they won't give any nutrition but will make you
even more hungry.  Tins made by you with a tinning kit are always homemade
if not cursed.  All other tins are one of these six possibilities: pureed
(500), deep fried (60), homemade (50), pickled (40), soup (20), and rotten
(-50).  The number in the parentheses is the nutrition value of each.  You
cannot tell in advance what type a given tin is.

When you eat deep fried food, you get slippery fingers for up to 15
rounds, making you drop your wielded weapon.  You can shorten the time by
(a)pplting a towel.  Don't forget to pick your weapon up again.

You can obtain intrinsics from eating tins, with the same chance that
you would have from eating the monster's corpse.  Note that the chance
of getting an intrinsic does not change if the tin is blessed or
cursed.

One of the most useful tins is the tin of spinach. If the tin is cursed,
you lose strength equivalent to eating a giant corpse.  Otherwise,
eating the spinach "makes you feel like Popeye" (or Swee'pea while
hallucinating) and gives you more strength equivalent to a giant corpse.
Tins of spinach have a nutrition of 600.


Other food
~~~~~~~~~~
(Quoted from a spoiler by Sascha Wostmann <wostmann@geocities.com>.)

Eating a spring of wolfsbane cures lycanthropy.

A carrot cures blindness.  Ever seen a rabbit with glasses?

Eating a fortune cookie gives you a rumor. You can also just (r)ead it
without eating the cookie.

Eating a lump of royal jelly increases (decreases if cursed) your
strength by one. If the jelly was cursed, you lose up to 20 hit points,
otherwise you gain up to 20 HP and your wounded legs heal. If your
actual HP would become higher than your maximum HP, there is a 1/17
chance of increasing your maximum HP by one.

Eating a cockatrice egg is a real bad idea if you're not polymorphed
into something that resists stoning.  However, they are very useful when
thrown at monsters.


Eating objects
~~~~~~~~~~~~~~
(Quoted from a spoiler by Sascha Wostmann <wostmann@geocities.com>.)

There are some conditions before you can eat an object. If you are
polymorphed into a metallivore (rock mole, rust monster, or xorn), you
may eat objects made of metal.

If you are polymorphed into a gelatinous cube, the object is organic,
and the object doesn't contain other objects, you may eat it.  This is
different for real gelatinous cubes, which can eat a container and hold
the non-organic contents of that container engulfed.  So when such a
beasty eats your chest with all the artifacts, you may find them on its
corpse.

You can never eat unique items such as the Amulet or the invocation
artifacts.

Eating something that isn't actually food always takes only one move.
The code addresses this issue by stating, "[We don't want] to deal with
partly eaten plate mails, players who polymorph back to human in the
middle of their metallic meal, etc...."

Eating rings has a 1/3 chance of conferring the intrinsic of the ring.
Eating amulets has a 1/5 chance of having an effect.  Not all intrinsics
can be acquired this way.  See the spoilers "amul-322.txt" and
"ring-322.txt".

When you eat a leash with a monster on the other side, this monster gets
unleashed.

If you eat the iron ball or the chain while you are punished, the
punishment is gone. If you eat the chain, the ball is still available to
use as a weapon or to throw.

When you try to eat something rustproof while being polymorphed into a
rust monster, you spit it out non-rustproof and get stunned a few rounds.

Eating a poisoned weapon has the same effect as eating poisonous corpses.
You get poisoned if you're not resistant.
