Stuffed and Starved
Just read most of this yesterday on a train journey back from London, and it's a great book for those teaching about issues related to food.
The supporting website has a range of resources which would be useful for those wanting additional reference material, including useful related YouTube clips.
On the Amazon.co.uk website you can currently "Look inside" the book...
Also lots of mentions of the word geography, which is always a bonus :)
