The first section of this chapter discusses how agriculture, food prices, and household incomes set the context for the types of diets that the poor can afford to eat, the prevalence of micronutrient malnutrition, and the conditions which will drive the effectiveness of various types of interventions that can be implemented to reduce micronutrient malnutrition. The second section discusses the numbers of people affected globally by mineral and vitamin deficiencies and what are functional consequences of these deficiencies. The third section describes agricultural and non-agricultural inventions, and their relative cost-effectiveness, that are currently being used to address the problem of micronutrient deficiencies.
