Vinayapiṭaka · Mahāvagga (2) · Vol. 5 · Section 62

[62] One who respectfully gives rice-gruel (yāgu) at the proper time to the restrained, who eat food given by others, furnishes ten things (ṭhānāni) upon that recipient. Life-span, beauty, happiness, strength, and eloquence arise for him from that; it dispels hunger and thirst, drives away wind, cleanses the bladder, and digests food. This has been praised by the Sugata as a medicine. Therefore, indeed, a person who desires happiness, or who aspires to heavenly pleasures, or who wishes for the finest of human splendor, should certainly always give rice-gruel.
