I'd like to learn about the history of quinoa, which is one of the hottest superfoods around.

Quinoa (pronounced KEEN-wah) is a grain that originated in South America and has been cultivated for over 5,000 years. It is a complete protein source containing all nine essential amino acids. The Incas called it "the mother grain" and considered it sacred. In fact, it was so important to their culture that they used it as currency. Today, quinoa is grown in many parts of the world, including the United States, where it is known as “supergrain” due to its high nutritional value.
