Taking a food systems approach is a promising strategy for improving diets. Implementing such an approach would require the use of a comprehensive set of metrics to characterize food systems, set meaningful goals, track food systems performance, and evaluate the impacts of food systems interventions. Food systems metrics are also useful to structure debates and communicate to policy makers and the general public. This paper provides an updated analytical framework of food systems and uses this to systematically identify relevant metrics and indicators based on data availability in low- and middle-income countries (LMICs). The list of indicators partly overlaps with the Sustainable Development Goals (SDG) indicators, but these do not cover all aspects of the food system. We conclude that public data are relatively available on food systems drivers and outcomes, and on some, but not all, of the activities. With only minor additional investments, existing surveys could be extended to cove

We conclude that public data are relatively available on food systems drivers and outcomes, and on some, but not all, of the activities. With only minor additional investments, existing surveys could be extended to cover a large part of the required additional data. For some indicators, targeted data collection efforts are needed. Because of the overlap with the SDG indicators, part of the collected data could serve not only to describe and monitor food systems, but to track progress towards attaining the SDGs.

Malnutrition in all its forms is a major challenge everywhere in the world, and particularly in low and middle income countries. To reduce malnutrition, innovations in food systems are needed to both provide sufficient options for consumers to obtain diets with adequate nutritional value, and to help consumers make conscious and unconscious choices to choose healthier diets. A potential solution to this challenge is food systems innovations designed to lead to healthier diets. In this paper, we lay out a multidisciplinary framework for both identifying and analyzing innovations in food systems that can lead to improvements in the choices available to consumers and their diets from a health perspective. The framework identifies entry points for the design of potential food systems innovations, highlighting potential synergies, feedback, and tradeoffs within the food system. The paper concludes by providing examples of potential innovations and describes future research that can be developed to support the role of food systems in providing healthier diets.

Food systems and diets are transforming rapidly in many parts of the world, particularly in low- and middle-income countries (LMIC). Changes in income, employment, taste, and location have direct implications for food choices and shopping patterns, which in turn have impacts on consumers’ nutrition and health, as well as environmental sustainability and resilience of the food system.

Considering the detrimental environmental impact of current food systems, and the concerns raised about their sustainability, there is an urgent need to promote diets that are healthy and have low environmental impacts. These diets also need to be socio-culturally acceptable and economically accessible for all. Acknowledging the existence of diverging views on the concepts of sustainable diets and healthy diets, countries have requested guidance from the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) on what constitutes sustainable healthy diets. These guiding principles take a holistic approach to diets; they consider international nutrition recommendations; the environmental cost of food production and consumption; and the adaptability to local social, cultural and economic contexts. This publication aims to support the efforts of countries as they work to transform food systems to deliver on sustainable healthy diets, contributing to the achievement of the SDGs at country level, especially Goals 1 (No Poverty), 2 (Zero Hunger), 3 (Good Health and Well-Being), 4 (Quality Education), 5 (Gender Equality) and 12 (Responsible Consumption and Production) and 13 (Climate Action).

How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

This paper, STEP 3, is the third of three background papers produced to inform the ‘Everyone Around the Table: FAO/GAIN Roundtable with Private Sector on Healthy Diets’ series of virtual roundtables which took place in July 2020. As in STEP 1 and STEP 2, the topics covered are relevant to all regions, but where possible a greater focus has been given to low- and middle-income countries. Small and medium enterprises (SMEs) are again a focus, given their role in the food systems of these regions (see STEP 1 for more detail), including their common presence in the food environments of many people living in poverty. STEP 3 (this paper) looks more closely at what it means to go to scale with healthy diets and better nutrition, providing examples and reflections for all stakeholders to consider.

Despite technological advances in agriculture, nearly a billion people around the world still suffer from hunger and poor nutrition while a billion are overweight or obese. This imbalance highlights the need not only to focus on food production but also to implement successful food policies. In this new textbook intended to be used with the three volumes of Case Studies in Food Policy for Developing Countries (also from Cornell), the 2001 World Food Prize laureate Per Pinstrup-Andersen and his colleague Derrill D. Watson II analyze international food policies and discuss how such policies can and must address the many complex challenges that lie ahead in view of continued poverty, globalization, climate change, food price volatility, natural resource degradation, demographic and dietary transitions, and increasing interests in local and organic food production. Food Policy for Developing Countries offers a "social entrepreneurship" approach to food policy analysis. Calling on a wide variety of disciplines including economics, nutrition, sociology, anthropology, environmental science, medicine, and geography, the authors show how all elements in the food system function together.
