This document discusses the history and value of bread. It notes that bread has been consumed for at least 30,000 years in many forms around the world. Bread was an important staple in early civilizations and enabled humans to become farmers rather than hunter-gatherers. The value placed on bread can shift dramatically based on circumstances, as seen in times of hyperinflation when the price of a single loaf of bread rose to billions or even trillions of currency units.
