It's all about context...
Take it to mean: "Hello good sir. I twas' once a meat eating gentleman like yourself, but I now enjoy the finer delicacies offered to those who prefer a diet rich in grains. I have munched on many an oat sack and shall continue to do so for it is by far a superior form of gastronomy. I regret, kind sir, to inform you of my decent into hedonism by allowing myself to feel the taint of dairy upon my lips, and have since begun to eat fine cheese with reckless abandon. Merrily yours, Sir Lugburz the XII".
.... or some other bullshit along those lines.
