Bananas are thought to have originated in Asia, with the Spanish introducing them to South America in the 1500s. People in the U.S. didn't get to eat bananas until the 1870s. Chocolate comes from the seeds of a tropical tree called cacao. Columbus took cacao back to Spain with him, but it didn't catch on until Cortez introduced it in the 1500s. For a long time it was considered a food for the rich.
Bananas are a great energy source.
Bananas ripen after harvest. As they turn yellow, starch is changed into sugar. Black spots indicate more sugar. Keep them in a cool place to slow ripening. A chocolate bar contains about the same amount of caffeine as a third of a cup of coffee.
