Good nutrition is fundamental to human health and wellbeing, yet according to the latest estimates from the UN Food and Agriculture Organization (FAO), about 805 million people—more than a tenth of the world’s population—remain chronically undernourished. In 2013, 161 million children younger than 5 years were affected by stunting, and 51 million by wasting. Undernourishment is the main underlying cause of death in this age group, accounting for 45% of child deaths worldwide. Meanwhile, more than 2 billion people are affected by deficiencies of micronutrients such as iodine, vitamin A, zinc, and iron.
