Eaten bread is soon forgotten.

A benefit can fade quickly from memory once it has been enjoyed. The saying points to the ease with which recipients may stop noticing help that previously mattered to them.

It can also express disappointment at ingratitude: someone accepts generosity or support, then behaves as though no kindness was ever shown. Here, bread figuratively represents a received benefit, provision, or kindness, not food alone.

Use it when a past favor, hospitality, or act of support is being overlooked after the recipient has benefited. It may be said ruefully about ordinary human forgetfulness or more critically when gratitude seems absent.
