Table 1. Impact of economic growth on health and nutrition1
Economic Growth and Nutrition
The nutrition research and practitioners community tends to focus on identification and improvement of targeted interventions; and rightly so, because complex problems need complex solutions. Yet, broad based economic changes need consideration as well. The positive impact of economic growth on health and nutrition outcomes is shown in Table 1. Across the 3 income groups (measured by GDP per capita), countries with higher economic growth have shown bigger reductions in both stunting and child mortality compared to countries in the same group with lower growth. An only exception is in the middle-income group; here we find that countries with lower growth have been more successful in reducing the prevalence of stunting. Innovation or total factor productivity growth comes into play by driving economic growth, which then can lead to an enhanced nutrition of the population. Of course, nature of growth – inclusive rather than growth captured by the wealthy – and public spending facilitated by increased national income, may be the real forces that translate growth into improved health and nutrition. This is not captured by the broad-brush tabulation in Table 1.
As economic growth accelerated in the past decade in Africa and South Asia, we should expect nutritional improvement in that region. In fact, there has been substantial progress in reducing undernutrition since 2000. Global Hunger Index (GHI) scores for Sub-Saharan Africa and South Asia have decreased significantly. Africa south of the Sahara has achieved the largest absolute improvement since 2000, followed by South Asia also with a sizable reduction. Among the 10 most successful countries in reducing their GHI in absolute terms from 2000 to 2016 are 8 countries from Sub-Sahara Africa [1].
Not only growth, but also good governance is positively correlated with the reduction of undernutrition. Indicators for good governance1 plotted against the reduction in the GHI suggest that the nutritional status and prevalence of hunger benefit from a safe and accountable policy environment as well as responsible and corruption-free leadership.
Governance is not only a matter of governments, but given their global reach, multinational food companies have a powerful role to play alongside governments, international organizations, and civil society in reducing hunger and impaired nutrition. The Access to Nutrition Index is an independent benchmarking tool that measures companies’ contributions to good nutrition against international norms and standards. According to the Access to Nutrition Index report from 2016 [2], “companies have shown improvement since 2013 in:
•Assigning top-level managerial responsibility and oversight to undernutrition.
•Explicitly committing to tackling micronutrient deficiencies in developing countries through targeted fortification of products.
•Reporting on engagement with governments in developing countries on undernutrition.”
The report shows that the world’s top food and beverage companies have taken some steps towards improving consumers’ diets. However, many of the companies are still lagging behind and overall greater efforts are required.
Drawing partly on recent reviews [3, 4], key success factors for the political economy of nutrition are:
1 Three sets of factors shape enabling environments for nutrition: knowledge and evidence, politics and governance, and capacity and resources.
2 Leadership for nutrition is fundamentally important for results.
The private sector has substantial potential to contribute to improvements in nutrition, but there is scarcity of credible evidence and trust.
4 Operational research of delivery, implementation, and the scaling of interventions, and contextual analysis is essential.

The Principal Challenge of Mapping Nutrition Goals and Instruments
The reduction of hunger and improvement of nutrition remain key policy goals in international policy. This is reflected in the United Nation’s Sustainable Development Goals (SDGs). The “Zero Hunger” goal No. 2 of the SDGs explicitly deals with ending the problem of hunger and all forms of malnutrition, which include hidden hunger, by 2030. The international political leaders commit to providing universal access to safe, nutritious, and sufficient food, in particular for the poor and people in vulnerable situations. Furthermore, virtually all other SDGs relate to nutrition directly or indirectly as well. However, there are trade-offs between specific policy goals that have to be taken into consideration.
In order to achieve a policy goal, there is a need for proper and well-defined instruments and specific actions. A prerequisite for effective and efficient policy action is that policy makers are equipped with more instruments than goals. Figure 1 presents an illustration of this principle emphasized by Tinbergen in the early 50s [5]. The defined goal of improving nutrition requires at least 2 instruments: (1) improving nutrition services and (2) generating or transferring income to the poor. Specific actions for improving nutrition services may include (1.1) (bio-)fortification of food, that is, increasing the content of micronutrients in food during processing or in the crops through agronomic practices, conventional plant breeding, or modern biotechnology and/or (1.2) promoting behavioral change. The second instrument would require a focus on (2.1) propelling agricultural productivity and/or (2.2) cash transfers.

The multi-dimensional character of nutrition challenges requires the deployment of a combination of multiple instruments and policy actions. This means that complex problems related for instance to income, food access, and micronutrient deficiencies require context specific combinations of interventions. Better nutrition policy therefore implies more coordination in policy making across different policy domains and innovative approaches, such as the combination of conditional cash transfers, employment guarantees, fortification, sanitation programs, small farm productivity programs, or mother and child focused nutrition interventions.
