To reorient food systems to ensure they deliver healthy diets that protect against multiple forms of malnutrition and diet-related disease and safeguard the environment, ecosystems, and natural resources, there is a need for better governance and accountability. However, decision-makers are often in the dark on how to navigate their food systems to achieve these multiple outcomes. Even where there is sufficient data to describe various elements, drivers, and outcomes of food systems, there is a lack of tools to assess how food systems are performing. This paper presents a diagnostic methodology for 39 indicators representing food supply, food environments, nutrition outcomes, and environmental outcomes that offer cutoffs to assess performance of national food systems. For each indicator, thresholds are presented for unlikely, potential, or likely challenge areas. This information can be used to generate actions and decisions on where and how to intervene in food systems to improve human and planetary health. A global assessment and two country case studies—Greece and Tanzania—illustrate how the diagnostics could spur decision options available to countries.

AbstractLivestock are a critically important component of the food system, although the sector needs a profound transformation to ensure that it contributes to a rapid transition towards sustainable food systems. This chapter reviews and synthesises the evidence available on changes in demand for livestock products in the last few decades, and the multiple socio-economic roles that livestock have around the world. We also describe the nutrition, health, and environmental impacts for which the sector is responsible. We propose eight critical actions for transitioning towards a more sustainable operating space for livestock. (1) Facilitate shifts in the consumption of animal source foods (ASF), recognising that global reductions will be required, especially in communities with high consumption levels, while promoting increased levels in vulnerable groups, including the undernourished, pregnant women and the elderly. (2) Continue work towards the sustainable intensification of livestock systems, paying particular attention to animal welfare, food-feed competition, blue water use, disease transmission and perverse economic incentives. (3) Embrace the potential of circularity in livestock systems as a way of partially decoupling livestock from land. (4) Adopt practices that lead to the direct or indirect mitigation of greenhouse gases. (5) Adopt some of the vast array of novel technologies at scale and design incentive mechanisms for their rapid deployment. (6) Diversify the protein sources available for human consumption and feed, focusing on the high-quality alternative protein sources that have lower environmental impacts. (7) Tackle antimicrobial resistance effectively through a combination of technology and new regulations, particularly for the fast-growing poultry and pork sectors and for feedlot operations. (8) Implement true cost of food and true-pricing approaches to ASF consumption.

Reformulation, a change to a food or beverage’s processing or composition, can reduce potentially harmful ingredients such as salt, added sugar, and saturated and trans fats or increase potentially beneficial ingredients or nutrients such as fiber, protein, and micronutrients. Poor nutrition and health outcomes of populations have stimulated programs and policies to reduce the intake of salt, added sugar, and unhealthy fats and increase healthy nutrients and ingredients to meet recommended targets of a healthy diet. Alongside promoting theconsumption of whole, nutritious foods (e.g., fruits, vegetables, and whole grains), reformulation, including fortification of processed foods, has been utilized by food industry manufacturers to contribute to improvingdiets and aligning with national dietary guidelines. This paper summarizes a literature review and twenty semistructured interviews with experts on food product reformulation and fortification to highlight the challenges,limitations, and opportunities for increasing their effectiveness. While studies have shown that reformulation could have beneficial public health impacts, such as iodized salt, there are a dearth of rigorous evaluations, particularly for some types of reformulations. Importantly, some evidence suggests that ultra-processing has significant adverse health effects independently of nutrient adequacy. To improve population health, reformulation should be complemented with a range of approaches, including food taxes and subsidies, public foodprocurement, restrictions on food advertising and marketing, front-of-pack labeling, and changes to food environments that improve availability, affordability, and demand for whole and minimally processed foods
