History and culture
Quinoa was first domesticated by Andean peoples around 3,000 to 4,000 years ago. It has been an important staple in the Andean cultures, where the plant is indigenous, but relatively obscure to the rest of the world. The Incas, who held the crop to be sacred, referred to it as chisoya mama or "mother of all grains", and it was the Inca emperor who would traditionally sow the first seeds of the season using "golden implements".
During the Spanish conquest of South America, the colonists scorned it as "food for Indians", and suppressed its cultivation, due to its status within indigenous religious ceremonies. The conquistadors forbade quinoa cultivation at one point, and the Incas were forced to grow wheat instead.
The United Nations General Assembly declared 2013 as the "International Year of Quinoa"  in recognition of the ancestral practices of the Andean people, who have preserved it as a food for present and future generations, through knowledge and practices of living in harmony with nature. The objective was to draw the world’s attention to the role that quinoa could play in providing food security, nutrition and poverty eradication in support of achieving Millennium Development Goals. Some academic commentary emphasised, however, that quinoa production could have ecological and social drawbacks in its native regions, and that these problems needed to be tackled.
