Well, this does actually apply to many countries that have suffered generational famine. In Vietnam I once ate a large broth of chicken... In that, the entire chicken was in their, two halves of its head and beak, intestines - the lot.

People have to make the most of what they have and often this is justified by calling things 'a delicacy' to make it seem more appealing. Cannibalism was significantly widespread in China, and there are poems and art about it during those times that are quite fascinating and, due to the above, china is somewhat unique in that it has 'learned cannibalism' culture around the nation.
