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.

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).

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

This guideline provides updated global, evidence-informed recommendations on the intake of free sugars to reduce the risk of NCDs in adults and children, with a particular focus on the prevention and control of unhealthy weight gain and dental caries. The recommendations in this guideline can be used by policy-makers and programme managers to assess current intake levels of free sugars in their countries relative to a benchmark. They can also be used to develop measures to decrease intake of free sugars, where necessary, through a range of public health interventions. Examples of such interventions and measures that are already being implemented by countries include food and nutrition labelling, consumer education, regulation of marketing of food and non-alcoholic beverages that are high in free sugars, and fiscal policies targeting foods and beverages that are high in free sugars. This guideline should be used in conjunction with other nutrient guidelines and dietary goals, in particular those related to fats and fatty acids (including saturated fatty acids and trans-fatty acids), to guide development of effective public health nutrition policies and programmes to promote a healthy diet.

Unhealthy diets are recognized globally as key contributors to morbidity and mortality. As food systems and diets evolve globally, the importance of monitoring what people eat has never been more critical. Yet, there is a lack of consensus on what constitutes healthy diets and how to measure them. In collective recognition of this challenge, the Healthy Diets Monitoring Initiative (HDMI), a partnership among FAO, UNICEF and WHO was established in 2022 with the mission of enabling national and global decision-makers and stakeholders to monitor and achieve healthy diets for people and the planet. We invite all national governments, United Nations agencies and international organizations, implementing partners, donors, civil society organizations, researchers and other key stakeholders (such as those concerned about climate change and food systems) to read our Call to Action and join the Healthy Diets Monitoring Initiative.

This publication contains practical guidance on the design, implementation and evaluation of appropriate food fortification programmes. They are designed primarily for use by nutrition-related public health programme managers, but should also be useful to all those working to control micronutrient malnutrition, including the food industry.The guidelines are written from a nutrition and public health perspective, and topics discussed include: the concept of food fortification as a potential strategy for the control of micronutrient malnutrition; the prevalence, causes, and consequences of micronutrient deficiencies, and the public health benefits of micronutrient malnutrition control; technical information on the various chemical forms of micronutrients that can be used to fortify foods; regulation and international harmonisation, communication, advocacy, consumer marketing and public education.
