Mbh 13.116.1

"'Yudhishthira said, "Alas, those cruel men, who, discarding diverse kinds of food, covet only flesh, are really like great Rakshasas! Alas, they do not relish diverse kinds of cakes and diverse sorts of potherbs and various species of Khanda with juicy flavour so much as they do flesh! My understanding, for this reason, becomes stupefied in this matter. I think, when such is the case, that, there is nothing which can compare with flesh in the matter of taste. I desire, therefore, O puissant one, to hear what the merits are of abstention from flesh, and the demerits that attach to the eating of flesh, O chief of Bharata's race. Thou art conversant with every duty. Do thou discourse to me in full agreeably to the ordinances on duty, on this subject. Do tell me what, indeed, is edible and what inedible. Tell me, O grandsire, what is flesh, of what substances it is, the merits that attach to abstention from it, and what the demerits are that attach to the eating of flesh."
