This report scientifically assesses the validity, usefulness, and fitness-for-purpose of existing healthy diet metrics for population assessment for global and national monitoring. Existing healthy diet metrics were identified and critically assessed through a set of criteria for their use as global and national monitoring indicators. After comparative evaluation, three healthy diet metrics were identified as the most suitable for global and national monitoring. The report highlights strengths and weaknesses for the existing healthy diet indicators. Some may be suitable for simple data collection tools and short data collection time while other indicators may require complex quantitative dietary information, lengthy data collection time, and might need to confirm the validity in various contexts. Some of them may only capture a limited number of the sub-constructs of the construct of healthy diets. The report underlines main knowledge gap regarding the population groups for which the metrics could be used – whether these indicators were developed for a particular demographic and/or socioeconomic groups and their ability to be used for other population groups. The report also identifies key priority areas to further explore how these indicators could be used for more population groups and settings.

It is vital for countries to monitor their population’s diets to inform actions toward improving the health of people and the planet. The healthiness of diets must be tracked in global frameworks, such as the Sustainable Development Goals (SDGs), to help monitor how the world’s population is faring. Currently, few countries regularly assess diets and there are no dietary indicators in global monitoring frameworks. Recognizing the importance of diets for health and the lack of consensus on how to measure and monitor healthy diets at scale, FAO, UNICEF and WHO joined forces to chart a way forward via the Healthy Diets Monitoring Initiative (HDMI). The joint mission of the HDMI is to enable national and global decision-makers and stakeholders to monitor and achieve healthy diets for people and the planet. The current guidance document is focused on healthy diets for healthy people. This version of the document provides an overview of the range of purposes for measuring the healthiness of diets and offers examples of the dietary assessment methods and types of dietary intake data, surveys and metrics that are currently available to monitor healthy diets.

With rapidly changing diets, the burden of disease due to the consumption of unhealthy diets is a worldwide concern. Assessment and monitoring of diets across countries and population groups is critical. However, there are no harmonized metrics for tracking how the healthfulness of diets around the world is evolving. Recognizing the need for consensus and action, and to chart a way forward, FAO, UNICEF, and WHO established the Healthy Diets Monitoring Initiative (HDMI) in 2022. The joint mission of this Initiative was articulated through discussions at a technical expert meeting in Bellagio, Italy, in late 2022. This meeting report includes the discussions and conclusions made on the suitability of existing metrics for assessment and monitoring of healthy diets nationally and globally. It also includes a workplan roadmap for the HDMI for the next two years towards the development of a global guidance on healthy diets metrics.

Food systems and diets underpin many critical challenges to public health and environmental sustainability, including malnutrition, noncommunicable diseases, and climate change, but sustainable healthy diets have the unique potential to reshape the future for both human and planetary well-being. The 2024 Global Food Policy Report draws on recent evidence to examine the role of food systems in driving nutrition outcomes and opportunities for transforming food systems to ensure healthy diets for all. Chapters by IFPRI researchers and partners evaluate proven and innovative ways to sustainably improve diet quality and reduce malnutrition, including ways to make healthy diets more affordable, accessible, and desirable, how to improve food environments, the role of both agricultural crops and animal-source foods, and governance for better diets and nutrition, all with a major focus on the most vulnerable populations in low- and middle-income countries. Regional sections explore the diverse challenges countries face and promising policy responses for transforming food systems for sustainable healthy diets.

Six years from 2030, hunger and food insecurity trends are not yet moving in the right direction to end hunger and food insecurity (SDG Target 2.1) by 2030. The indicators of progress towards global nutrition targets similarly show that the world is not on track to eliminate all forms of malnutrition (SDG Target 2.2). Billions of people still lack access to nutritious, safe and sufficient food. Nevertheless, progress in many countries provides hope of the possibility of getting back on track towards hunger and malnutrition eradication. Implementing the policies, investments and legislation needed to revert the current trends of hunger, food insecurity and malnutrition requires proper financing for food security and nutrition. Despite a broad agreement on the urgent need to increase financing for food security and nutrition, the same cannot be said for a common understanding regarding how this financing should be defined and tracked. The report provides a long-awaited definition of financing for food security and nutrition and guidance for its implementation. There are recommendations regarding the efficient use of innovative financing tools and reforms to the food security and nutrition financing architecture. Establishing a common definition of financing for food security and nutrition, and methods for its tracking, measurement and implementation, is an important first step towards sustainably increasing the financing flows needed to end hunger, food insecurity and all forms of malnutrition, and to ensure access to healthy diets for all, today and tomorrow.

Sustainable Food System Assessment provides both practical and theoretical insights about the growing interest in and response to measuring food system sustainability. Bringing together research from the Global North and South, this book shares lessons learned, explores intended and actual project outcomes, and highlights points of conceptual and methodological convergence. Interest in assessing food system sustainability is growing, as evidenced by the Milan Urban Food Policy Pact and the importance food systems initiatives have taken in serving as a lever for attaining the UN Sustainable Development Goals. This book opens by looking at the conceptual considerations of food systems indicators, including the place-based dimensions of food systems indicators and how measurements are implicated in sense-making and visioning processes. Chapters in the second part cover operationalizing metrics, including the development of food systems indicator frameworks, degrees of indicator complexities, and practical constraints to assessment. The final part focuses on the outcomes of assessment projects, including impacts on food policy and communities involved, highlighting the importance of building connections between sustainable food systems initiatives. The global coverage and multi-scalar perspectives, including both conceptual and practical aspects, make this a key resource for academics and practitioners across planning, geography, urban studies, food studies, and research methods. It will also be of interest to government officials and those working within NGOs.

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).

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

At the 2013 Nutrition for Growth Summit in London, 96 signatories (governments, civil society organizations, donors, United Nations’ agencies, and businesses) agreed to support the creation of an annual report on global nutrition that would be authored by an independent expert group, in partnership with a large number of contributors. The first edition of this report, the Global Nutrition Report 2014, puts a spotlight on worldwide progress by the 193 member countries of the United Nations in improving their nutrition status, identifies bottlenecks to change, highlights opportunities for action, and contributes to strengthened nutrition accountability on country and global levels.
