There is a published poem from the age, that meantions starving english and not being allow to hunt for rabbit. Getting hands cut off or something

OPs text definitely is flourished

England was basiclly the Norman hunting ground

( in not a meat maxi - for the record. I love my nuts, seeds and beans )

Also, Im not convinced there was a big church influence before the Normans

They knew what is real food and what is the food for plebs. You do not need organized modern science to know what tastes good and what not. Similar differences in the food given to soldiers in comparison to officers always existed even in Roman times
