Despite global goals to decrease malnutrition, there remain many challenges in providing access to a nutritious diet for all. Food value chains for nutrition have been the focus of a number of reviews but evidence of their impacts remains limited. Using a systems perspective to look at markets and the role of the private sector in nutrition includes not only the complex relations between multiple actors and trade-offs between often competing objectives, but also the supporting environment in terms of infrastructure (e.g. roads, energy) and the guiding laws and social norms.
In the past, discussions about food security have typically focused on thequantity of food that people eat rather than the quality. However, micronutrient deficiencies are becoming increasingly recognized as a serious threat to the health and economic development of low-income populations. As a result, nutrition is garnering more and more attention in the development community.
