<human>: Can you tell me the history of quinoa?
<bot>: Quinoa is a grain-like crop that originated in South America. It was first cultivated by the Incas around 3000 BC and spread throughout the Andes Mountains. The Incas used it as a staple food source, especially during times of famine. In the 16th century, Spanish explorers brought quinoa back to Europe, where it became popular among European nobility. During the 19th century, quinoa experienced a resurgence in popularity due to its health benefits. Today, quinoa is grown in over 30 countries across the world, with the United States being one of the largest producers.
