TO GO WITH AFP STORY A worker shows quinoa seeds in Cotimbora, Oruro, Bolivia, some 440 km from La Paz, on November 8, 2011. The nearby city of Uyuni opened on November 2014 to world's first quinoa milk factory. Quinoa, a good crop for harsher climes as it prospers in semi-arid conditions and high altitudes where rivals struggle, has nutrition experts salivating as it is chock full of protein and essential amino acids. The grain-like quinoa has been grown in the Andes for 7,000 years and Bolivia is now pushing it as a potential answer to global food shortages.
