Measures of malnutrition beyond calories: 2 billion are deficient in 1 or more micronutrients
26 percent of world's children are stunted "...2 billion people suffer from one or more micronutrient deficiencies and 1.4 billion people are overweight, of whom 500 million are obese." "Child and maternal malnutrition.... impose by far the largest nutrition-related health burden at a global level." "Undernutrition and micronutrient deficiencies must therefore continue to be the highest nutrition priority for the global community in the immediate future."
