Food / Where can I find information for a Poland Foods assignment? [12]

I need to research factors that affect the availability of food, such as climate, geography, economy, technology and staple foods in Poland.

Also, factors that influence the acceptability of food such as social structure, religion, history and ethnicity.

And information or links to sites where I could find this information would be a huge help, I'm doing this for an assignment in foods class. I'm just finding it hard to locate any of this information and don't know where else to look. Thanks guys! :)
