Chenopodium Species: From Weeds to a Healthy Food Grain 'Quinoa'

Genus Chenopodium has about 250 species, which mostly grow as weeds throughout the world. In India, the most common species is Chenopodium album L., which grows as a weed in wheat fields in the north. Its foliage is used as a green vegetable, while the seed is used in the hilly regions for making gruel and mild alcoholic beverages. However, people of Andes, South America have domesticated and developed Chenopodium quinoa (popularly known as quinoa) as an excellent food-grain crop since the past several millennia. Quinoa received global attention in the wake of human intolerance to gluten in wheat resulting in celiac disease, and its demand has largely increased. The United Nations General Assembly declared 2013 as the International Year of Quinoa. The leading country in the world producing quinoa is Peru, followed by Bolivia. However, considering the demand and high market prices, a number of countries, including India have started growing quinoa. However, farmers in India are facing problem in marketing the crop, because there is no local consumption and exporting a farm product is problematic. India has a variety of food grains, including pearl millet, sorghum and several minor millets to tackle gluten intolerance and celiac disease.
