Once you study the bible sufficiently with the help of the Holy Spirity (the third person of the triune God) you get a real familiarity with both the nature and attributes of the God who created us and Jesus Christ himself as the Word (the second person of the triune God that took on human nature) and what Christ did and thought and felt in His humanity.
(And of course this relives one of the torturous exercise of making every utterance recorded by God to fit into a preconcieved notion of what we readers think He must have meant for it to mean so that everything God said is internally consistant (according to "whomever") rather than simply taking some utterances as hints of wondrous realities that God has only teased us with in the bible---as any good father might do with his children.)
The bible doesn't list everything that is true; it does not always address the specifics we would like answers to. Personally, I find it is reasonable to assume that Christ partook of some if not all of the dietary availabilities appropriate to the time in which He lived. Lamb was a part of Passover and meat in general was allowed to be eaten by the Jews under specific restrictions under the Mosaic law.
And I would cite 1 Timothy 4: 1...11 ----not as proof, but as insight.
