-The spell of detect food has a niche for finding food on the hero's current level whenever you are short on [[permafood]], though the spell itself does not mark whether those food sources are safe or not, e.g. [[corpse]]s that are [[tainted]] from age, [[poisonous]], cause [[stoning]], and so on. The closest to a safeguard that the spell offers is the food appraisal intrinsic granted from casting the spell at Skilled, although the intrinsic will expire after warning you of potentially dangerous food regardless of if you elect to eat it or not. Even so, the spell's lack of nutrition burn and the ability to cast it when low on food can still be potentially life-saving by themselves on occasion.

 The spell naturally loses much of its value as the hero amasses a cache of permafood, especially once they can clear [[Fort Ludios]] or the [[Castle]], but it can still be useful if the hero is Skilled in divination spells: they can apply the aforementioned food appraisal intrinsic as a safeguard against typos or eating corpses with misremembered ages. The spell can also be used to check for the corpses of [[reviving]] monsters such as [[Troll (monster class)|trolls]] and track whether or not they have resurrected.

-The obvious use is finding food on the level if you are short on [[comestible#Rotten_food|permafood]], and can be used to train other [[divination spells]]. This can be a real lifesaver in a fix, but beware - it will also display [[tainted]] and [[poison]]ed [[corpse]]s, as well as corpses that can cause [[petrification]] or other harmful effects.

-As you go deeper into the dungeons, food becomes more abundant, and this spell loses much of its base value. However, once you become Skilled or Expert in divination, you can use it as a faux-permanent [[food appraisal]] intrinsic by recasting every time you get a warning, as it drains very little energy.
