Getting people to change what they eat is tough. Changing a whole farming system is even tougher. The southern Indian state of Karnataka is quietly trying to do both, with a group of cereals that was once a staple in the state: millet.
Until about 40 years ago, like most of India, the people of Karnataka regularly ate a variety of millets, from finger millet (or ragi) to foxtail millet. They made rotis with it, ate it with rice, and slurped it up at breakfast as porridge.
