What did Jesus eat in relationship to his Jewish culture and tradition?

**What did Jesus eat in relationship to his Jewish culture and tradition?** We all know that the Jews of Jesus' days observed many dietary laws that were laid down by God. What I am interested in knowing is a little more nuanced in regards to Jewish culture and tradition at the time of Jesus. For example, both wheat and barley were grown and eaten by the ancient Jews. However is there any historical references that state when barley loaves would be consumed over loaves made with wheat? I know that many Christian traditions use hosts made with wheat in their communion services, yet the Gospels also recounted the story of two fish and five loaves made of barley loaves [(John6:9)](https://www.biblegateway.com/passage/?search=John%206%3A9&version=NIV) . Do we have any historical records as to when one particular Jew food stuffs would be traditional used over another Jewish alternative? Although I would like an answer to the question in regards to the usage of wheat over barley, I am not limiting this post to these two food stuffs. There may be a Jewish preference or tradition in eating a particular fish on Jewish feasts over everyday meals!
