Soldiers hand out chocolate to French children during WWII.

Three cheers for chocolate!

In 1875, the first milk chocolate was introduced to the market by Daniel Peter of Switzerland. Chocolate became so popular around the world that even during World War II the U.S. government shipped cocoa beans to the troops. Today, the U.S. Army includes chocolate bars in their rations. Chocolate has even been taken into space as part of the diet of U.S. astronauts.
