AbstractIt is not known whether dietary guidelines proposing a limited intake of animal protein are compatible with the adoption of circular food systems. Using a resource-allocation model, we compared the effects of circularity on the supply of animal-source nutrients in Europe with the nutritional requirements of the EAT-Lancet reference diet. We found the two to be compatible in terms of total animal-source proteins but not specific animal-source foods; in particular, the EAT-Lancet guidelines recommend larger quantities of poultry meat over beef and pork, while a circular food system produces mainly milk, dairy-beef and pork. Compared with the EAT-Lancet reference diet, greenhouse gas emissions were reduced by up to 31% and arable land use reduced by up to 42%. Careful consideration of the feasible substitutability between animal-source foods is needed to define potential roles of animal products in circular human diets.

Circular System

Abstract Several dietary guidelines are developed that propose limiting the intake of animal protein to stay within planetary boundaries and improve human health. Simultaneously, circular food systems are receiving significant attention in the European Union as an option to improve the current food system. In a circular system, animals are solely fed with low-opportunity-cost-biomass (LCB), resulting in substantially fewer animals and reduced supply of animal-sourced nutrients to humans. We assessed whether this circularity principle within the EU-28 is compatible with the recommended animal-source food consumption in healthy and environmentally friendly dietary guidelines such as the EAT-LANCET dietary guidelines. Our results show that the overall quantity of animal-sourced protein in EAT-LANCET dietary guidelines can be met, but that the precise levels of inclusion of different animal-sourced foods in such a diet cannot be achieved. The EAT-LANCET guidelines recommend larger quantities of chicken meat over beef and pork while a circular food system produces mainly milk, dairy-beef, and pork. All three circularity diets outperform the EAT-LANCET diet in nutritional value while reducing GHG emissions (up-to 31%) and arable land use (up-to 42%). Careful consideration of the permissible substitutability between animal-sourced foods is urgently needed to define the role of animal products in circular human diets. In this way the consumption of animal products - based on the circularity principle of only feeding animals with LCB - benefits both human health and the environment.

Healthy Diets

There are approximately 100 countries with food-based dietary guidelines throughout the world, each of which aims to encompass the cultural, geographical, and health considerations unique to their country of origin. Common themes throughout these guides emphasize diverse and balanced intake of food groups from both plant- and animal-sources. With the globally recognized need to shift to more sustainable food systems, several countries and international food and health organizations have begun to incorporate sustainability recommendations into their dietary guidance. These sustainability recommendations are often based on food source (i.e., eat more plant-source and fewer animal-source foods), yet food source may not be the only useful or informative comparator for assessing healthy and sustainable diets. The purpose of this narrative review is to examine the roles of plant-source foods and animal-source foods in the context of sustainable healthy diets—with an emphasis on the contributions of the most commonly recommended food groups from global food-based dietary guidelines (i.e., fruits, vegetables, and dairy foods). Overall, plant and animal agriculture have complementary and symbiotic roles in healthy and sustainable food systems, and these abilities are largely dependent on various contextual factors (e.g., geography, production practices, processing methods, consumption patterns)—not just on whether the food originated from the plant or animal kingdom.

The Impact

Abstract Background Consumer trust in food systems is essential for consumers, food industry, policy makers and regulators. Yet no comprehensive tool for measuring consumer trust in food systems exists. Similarly, the impact that trust in the food system has on health-related food behaviours is yet to be empirically examined. The aim of this research was to develop a comprehensive instrument to measure trust in the food system (the Dimensions of Trust in Food Systems Scale (DOTIFS scale) and use it to explore whether trust in the food system impacts consumers’ health-related behaviours. Methods The DOTIFS scale was developed using sociological theories of trust and pre-existing instruments measuring aspects of trust. It was pilot tested and content validity was assessed with 85 participants. A mixed-methods exploration of the health-related behaviours of 18 conveniently sampled Australian consumers with differing trust scores determined by the DOTIFS scale was then conducted. During March–July 2019 shopping- and home-observations were used to assess participants’ food safety practices and exposure to public health fortification programs, while the CSIRO Healthy Diet Score determined their adherence to national dietary guidelines. Results The DOTIFS scale was found to have high comprehension, ease of use and content validity. Statistical analysis showed scale scores significantly trended as predicted by participants’ stated level of trust. Differences were found in the way individuals with more or less trust in the food system comply with national dietary guidelines, are exposed to public health fortification programs, and adhere to recommended food safety practices. Conclusions The DOTIFS scale is a comprehensive, sociologically- and empirically- informed assessment of consumer trust in food systems that can be self-administered online to large populations and used to measure changes in consumer trust over time. The differences in health-related behaviours between individuals with varying levels of trust warrant further investigation.

Nutritional Needs

Achieving sustainable, ethical food systems in support of human and planetary health is among the greatest challenges facing the global community. Globally, 815 million people are chronically undernourished, 108 million children and 604 million adults are obese, and more than two billion people are at risk of micronutrient deficiencies. Animal-source foods (ASFs), including milk, meat, fish, and eggs, provide high-quality protein and a variety of micronutrients in forms readily absorbed and used by the human body. Current research continues to explore the nutritional contributions of ASFs, their interactions with other dietary components, and their role in healthy human growth and development. This chapter uses the framework of the sustainable development goals (SDGs) to consider the value of ASFs in human diets across a range of settings. It discusses opportunities for multidisciplinary efforts that harness science, technology, and innovation (STI) to mitigate risks of foodborne disease, to promote the efficient management of natural resources, to reduce nutrient losses within livestock value chains, and to support gender- and culturally sensitive communication around livestock management and human nutrition. In support of the economic, social, and environmental dimensions of sustainable development, this chapter proposes opportunities to meet the nutritional needs of current and future populations while supporting biodiversity and conserving scarce natural resources.

Governance Model

Community catering or to use another common term especially in the American literature institutional foodservice plays a central role in changing our food system towards sustainability. Community catering establishments can bring about changes in this context at various levels. Hence, in the context of menu planning, they have a direct influence on the level of meat consumption. Indirectly, however, they can also support changes in eating habits by offering the guest an equally attractive alternative, thus giving him or her a sense of how tasty a low-meat cuisine can be. On the basis of this experience, the consumer may possibly change in turn his or her own purchasing behavior and menu planning at home. With the increasing importance of catering for day-care centers and schools, community catering also has a considerable influence on the nutritional status as well as on the development of people’s individual diet and the later eating habits of young people. By understanding socio-technical systems as embedded in ecological systems this paper takes a systemic view on innovations in transformation domains as the objects of desire for governance towards sustainability. The framework developed in the context of the BMBF-funded research project “Governance model for socio-ecological transformation processes in practice: development and testing in three areas of application” known by its acronym TRAFO 3.0 was applied to examine innovative approaches and actors in community catering and their contributions to more sustainable food systems. A number of studies show that a very large environmental relief potential can be achieved by reducing the quantity of meat and other animal products offered. However, the concrete implementation of this goal is associated with a multitude of challenges, since meat-containing meals are an important part of German food culture. How the transformation towards meals with fewer animal products in German community catering can succeed is an important question in the context of the transformation to sustainable food systems. To answer this question, we analyzed the status quo of the socio-technical system of German community catering using a developed governance model. One of the central results was that community catering stakeholders who have successfully reduced their offer of animal products died fundamental changes in meal planning. Cooks had to “reinvent” meals completely to be successful.

AbstractThe nutrition transition transforms food systems globally and shapes public health and environmental change. Here we provide a global forward-looking assessment of a continued nutrition transition and its interlinked symptoms in respect to food consumption. These symptoms range from underweight and unbalanced diets to obesity, food waste and environmental pressure. We find that by 2050, 45% (39–52%) of the world population will be overweight and 16% (13–20%) obese, compared to 29% and 9% in 2010 respectively. The prevalence of underweight approximately halves but absolute numbers stagnate at 0.4–0.7 billion. Aligned, dietary composition shifts towards animal-source foods and empty calories, while the consumption of vegetables, fruits and nuts increases insufficiently. Population growth, ageing, increasing body mass and more wasteful consumption patterns are jointly pushing global food demand from 30 to 45 (43–47) Exajoules. Our comprehensive open dataset and model provides the interfaces necessary for integrated studies of global health, food systems, and environmental change. Achieving zero hunger, healthy diets, and a food demand compatible with environmental boundaries necessitates a coordinated redirection of the nutrition transition. Reducing household waste, animal-source foods, and overweight could synergistically address multiple symptoms at once, while eliminating underweight would not substantially increase food demand.

Increasing efficiency in livestock production and reducing the share of animal products in human consumption are two strategies to curb the adverse environmental impacts of the livestock sector. Here, we explore the room for sustainable livestock production by modelling the impacts and constraints of a third strategy in which livestock feed components that compete with direct human food crop production are reduced. Thus, in the outmost scenario, animals are fed only from grassland and by-products from food production. We show that this strategy could provide sufficient food (equal amounts of human-digestible energy and a similar protein/calorie ratio as in the reference scenario for 2050) and reduce environmental impacts compared with the reference scenario (in the most extreme case of zero human-edible concentrate feed: greenhouse gas emissions −18%; arable land occupation −26%, N-surplus −46%; P-surplus −40%; non-renewable energy use −36%, pesticide use intensity −22%, freshwater use −21%, soil erosion potential −12%). These results occur despite the fact that environmental efficiency of livestock production is reduced compared with the reference scenario, which is the consequence of the grassland-based feed for ruminants and the less optimal feeding rations based on by-products for non-ruminants. This apparent contradiction results from considerable reductions of animal products in human diets (protein intake per capita from livestock products reduced by 71%). We show that such a strategy focusing on feed components which do not compete with direct human food consumption offers a viable complement to strategies focusing on increased efficiency in production or reduced shares of animal products in consumption.

AbstractObjectiveDietary diversity, and in particular consumption of nutrient-rich foods including fruits, vegetables, nuts, beans and animal-source foods, is linked to greater nutrient adequacy. We developed a ‘dietary gap assessment’ to evaluate the degree to which a nation’s food supply could support healthy diets at the population level.Design/SettingIn the absence of global food-based dietary guidelines, we selected the Dietary Approaches to Stop Hypertension (DASH) diet as an example because there is evidence it prevents diet-related chronic disease and supports adequate micronutrient intakes. We used the DASH guidelines to shape a hypothetical ‘healthy’ diet for the test country of Cameroon. Food availability was estimated using FAO Food Balance Sheet data on country-level food supply. For each of the seven food groups in the ‘healthy’ diet, we calculated the difference between the estimated national supply (in kcal, edible portion only) and the target amounts.ResultsIn Cameroon, dairy and other animal-source foods were not adequately available to meet healthy diet recommendations: the deficit was −365 kcal (–1527 kJ)/capita per d for dairy products and −185 kcal (–774 kJ)/capita per d for meat, poultry, fish and eggs. Adequacy of fruits and vegetables depended on food group categorization. When tubers and plantains were categorized as vegetables and fruits, respectively, supply nearly met recommendations. Categorizing tubers and plantains as starchy staples resulted in pronounced supply shortfalls: −109 kcal (–457 kJ)/capita per d for fruits and −94 kcal (–393 kJ)/capita per d for vegetables.ConclusionsThe dietary gap assessment illustrates an approach for better understanding how food supply patterns need to change to achieve healthier dietary patterns.

Abstract Recent discussions of healthy and sustainable diets encourage increased consumption of plants and decreased consumption of animal-source foods for both human and environmental health. Seafood is often peripheral in these discussions. This paper examines the relative environmental costs of sourcing key nutrients from different kinds of seafood, other animal-source foods, and a range of plant-based foods. We linked a nutrient richness index for different foods to life cycle assessments of greenhouse gas (GHG) emissions in the production of these foods to evaluate nutritional benefits relative to this key indicator of environmental impacts. The lowest GHG emissions to meet average nutrient requirement values were found in grains, tubers, roots, seeds, wild-caught small pelagic fish, and farmed bivalve shellfish. The highest GHG emissions per nutrient supply are in beef, pork, wild-caught prawns, farmed catfish, tilapia and farmed crustaceans. Among animal-source foods, some fish and shellfish have GHG emissions at least as low as plants and merit inclusion in food systems policymaking for their potential to support a healthy, sustainable diet. However, other aquatic species and production methods deliver nutrition to diets at environmental costs at least as high as land-based meat production. It is important to disaggregate seafood by species and production method in ‘planetary health diet’ advice.

This chapter examines the link between dietary choices and greenhouse gas (GHG) emissions and possible interventions to reduce this impact. The connections between climate change, food systems and public health are explored. It is shown that there is variance in the impact of different food types on GHG emissions, with animal products having the greatest impact. The role of food system activities in the production of GHG emissions is also explored. Dietary choices and GHG emissions are examined using case studies from a variety of countries. Results show that reduced animal food production has increased potential to reduce GHG emissions compared to technological mitigation or increased productivity measures. Finally, a systems science approach is used to explore possible interventions aimed at reducing consumption of animal products.
