Every moving thing that lives shall be food for you; even as the green plants have I given you all things.
Read Chapter 9

Meat. The more religious, at least, had hitherto abstained from flesh, being content with herbs: which had been expressly granted. Now, the salt waters of the deluge had vitiated the earth, its plants were no longer so nutritive. (Menochius)
God gives leave to eat flesh meat, but with some restriction, that we may still learn to obey. (Worthington)
You [Trypho, a Jew] object that Noah was ordered to make a distinction between the herbs, because we do not now eat every kind of herb. Such a conclusion is inadmissible. I could easily prove, but we will not spend the time now in doing so, that every vegetable is an herb and may be eaten. Now, if we make a distinction between them and refuse to eat some of them, we do so not because they are common and unclean but because they are bitter, or poisonous or thorny.
