26 Mar 2018 --- A study by a team of IIASA researchers has explored ways to reduce micronutrient deficiencies in India affordably while also reducing greenhouse gas emissions. The researchers used the National Sample Survey of Consumption Expenditure in India to examine Indian diets, which showed that more than two-thirds of the Indian population, around 500 million people, are affected by deficiencies in micronutrients such as protein, iron, zinc and vitamin A, which contributes to lower life expectancies.
