The stark observation of the co-existence of undernourishment, nutrient deficiencies and overweight and obesity, the triple burden of malnutrition, is inviting us to reconsider health and nutrition as the primary goal and final endpoint of food systems. Agriculture and the food industry have made remarkable advances in the past decades. However, their development has not entirely fulfilled health and nutritional needs, and moreover, they have generated substantial collateral losses in agricultural biodiversity. Simultaneously, several regions are experiencing unprecedented weather events caused by climate change and habitat depletion, in turn putting at risk global food and nutrition security. This coincidence of food crises with increasing environmental degradation suggests an urgent need for novel analyses and new paradigms. The sustainable diets concept proposes a research and policy agenda that strives towards a sustainable use of human and natural resources for food and nutrition security, highlighting the preeminent role of consumers in defining sustainable options and the importance of biodiversity in nutrition. Food systems act as complex social–ecological systems, involving multiple interactions between human and natural components. Nutritional patterns and environment structure are interconnected in a mutual dynamic of changes. The systemic nature of these interactions calls for multidimensional approaches and integrated assessment and simulation tools to guide change. This paper proposes a review and conceptual modelling framework that articulate the synergies and tradeoffs between dietary diversity, widely recognised as key for healthy diets, and agricultural biodiversity and associated ecosystem functions, crucial resilience factors to climate and global changes.

This conversation is part of a special issue on “Critical Nutrition” in which multiple authors weigh in on various themes related to the origins, character, and consequences of contemporary American nutrition discourses and practices, as well as how nutrition might be known and done differently. In this section, authors reflect on the limits of standard nutrition in understanding the relationship between food and human health. They also focus on how nutrition practitioners are or could be creating different practices for how nutritional information is made available, shared, and absorbed. Among the different frameworks under discussion are individualized nutrition, ecological nutrition, critical dietary literacy, feminist nutrition, and technologies of humility.

Achieving a better understanding of the consequences of nutrition to animal fitness and human health is a major challenge of our century. Nutritional ecology studies increasingly use nutritional landscapes to map the complex interacting effects of nutrient intake on animal performances, in a wide range of species and ecological contexts. Here, we argue that opening access to these hard-to-obtain, yet considerably insightful, data is fundamental to develop a comparative framework for nutrition research and offer new quantitative means to address open questions about the ecology and evolution of nutritional processes.

Maternal undernutrition is a complex condition that arises from various factors, including social, cultural, psycho-social, biological, and ecological factors. The intergenerational consequences of chronic malnutrition, starting with mothers and their children, account for a significant proportion of infant deaths, cognitive disability, and reduced productivity in adulthood. Therefore, having nutritional knowledge throughout pregnancy is crucial for better risk assessment of undernutrition and healthy pregnancy outcomes. The study examined whether trimester-specific nutrition education and awareness could significantly impact the relationship between maternal nutrition and birth outcomes and found that this association was stronger in women with higher levels of nutrition knowledge. As a result, a food-based approach that is both low-cost and high-nutrition can help meet the specific nutritional requirements of pregnancy, alter certain nutrients that target fetal metabolic vulnerabilities, or enhance fetal growth and development in the migrant population. The review explores recent research and discusses how nutrition literacy and knowledge influence pregnancy and birth outcomes, providing an overview of the current understanding of maternal nutritional trimester-specific needs and highlighting areas that still require further study. The findings emphasize the importance of considering diet diversity and peer support during pregnancy, considering the impact that nutrition knowledge has on pregnancy outcomes.

Abstract Ruminant livestock-production systems are between a rock and a hard place; they are experiencing increasing societal pressure to reduce environmental impacts in a world that demands increased food supply. Recent improvements in the understanding of the nutritional ecology of livestock by scientists may help livestock producers respond to these seemingly contradictory demands. Forages are nutrition and pharmacy centers with primary (nutrients) and plant secondary compounds (PSC; pharmaceuticals, nutraceuticals), which can provide multiple services for the proper functioning of agroecosystems. Legumes with lower contents of fiber and higher contents of nonstructural carbohydrates, coupled with different types and concentrations of PSC (e.g., condensed tannins, terpenes), create a diverse array of chemicals in the landscape (i.e., the “chemoscape”) with the potential to enhance livestock nutrition, health and welfare relative to foodscapes dominated by grasses and other conventional feeds. These PSC-containing plants may reduce methane emissions and nitrogen (N) excretion from animals while increasing animal growth rate compared with swards dominated by grasses, and provide meat quality that appeals to consumers. Condensed tannins from sainfoin and saponins from alfalfa and manure of cattle consuming these forages also reduce N mobilization in soils, reduce nutrient leaching, and increase plant-available N stores for future use. The challenge for future pastoral production systems is to design multifunctional spatiotemporal arrangements of forages with “ideal” chemical diversity for specific ecoregions, aiming to achieve sustainability while increasing production goals and improving ecosystem services. Thus, the objective of this review is to stimulate the quest for chemically and taxonomically diverse pastoral feeding systems that optimize overall productivity; reduce environmental impacts; and enhance livestock, soil, and human health.

Although I admire the scientific discipline, I frequently find myself wondering whether the traditional approach to science involving testable hypotheses, replication, statistical significance and repeatability is adequate to meet the challenge of understanding such things as the complexity of whole ecological systems without taking apart and destroying the very object of the study.

Human subsistence is highly dependent on food. Food offers essential nutrients for the healthy growth and development of all cells in the body; as well as providing energy for day-to-day activities. A healthy diet focuses on balance. This refers to consuming the right foods in the proper proportions to maintain a healthy weight and optimize the body's metabolic processes. Today, the nutrition arena has evolved rapidly. In developed countries, nutritional deficiencies efforts have shifted to managing excessive calories, inactive lifestyles and stress. Nutritional and technological advances concurrently curbed nutrient deficiency diseases, while abutting the growing concerns on obesity, noncommunicable diseases and ageing. Acknowledging the nutritional guidelines worldwide, it is imperative to look at the “new-old” approaches to maintaining a wholesome diet to ensure a healthy lifestyle. In the 1980s, the University of Giessen came forward with the concept of ‘Wholesome Nutrition’ which is a concept of sustainable nutrition. It comprises health and the ecological, economic, social and cultural dimensions of nutrition. Later, sustainable nutrition incorporates the environment, economy, society, health and culture. On the other hand, past lessons and observing the good manners of the previous Muslims are recommended by Islamic principles. Among similarities in the core elements discussed by both are the preference for plant-based foods and minimally processed products. This article discusses the approaches by the West on the concept of sustainable nutrition; and eating habits by early Muslims in achieving wholesome nutrition.

Nutritional problems of every category of pigs are presented in this paper. Nutrition of pigs is in constant changes adapting to the improvements of genetics potential as well as to the very severe ecological demands. As far as piglets just weaned are concerned, the nutrition problem is solved by means of adequate mixture with additives so that performance at this stage is remarkably increased. Nutritional problems of pregnant and lactating sows are analyzed. In pregnancy it is attempted to involve in practice cheap mixtures low in concentration of nutrients, while the needs of lactating animals are constantly increasing. As for fattening animals, a significant improvement is expected in the period to come if a multiphase feeding system is applied. At the same time such a system gives an opportunity to use rationally liquid by-products of the food processing industry with the maximum adaptive possibilities to the needs of pigs.

Nutrition in infancy contributes to a significant portion on the notion of the importance of nutrition during the first 1000 days of life. A vast pool of literature exists on the importance of nutrition during this phase of life with future diseases, obesity and mental health. However, despite the availability of many guidelines and policies revolving around infant feeding practices, adherence to it remains poor. This review explains factors that influence infant feeding practices from an ecological point of view. A Bronfenbrenner ecological model was used to argue the influence and interaction of various ecological factors on infant feeding practices. The review highlights that the way these factors affect infant feeding differs according to populations and settings. This review suggests the need for more robust and population sensitive interventions to improve infant feeding practices globally.

Apex predators play pivotal roles in marine ecosystems, mediated principally through diet and nutrition. Yet, compared with terrestrial animals, the nutritional ecology of marine predators is poorly understood. One reason is that the field has adhered to an approach that evaluates diet principally in terms of energy gain. Studies in terrestrial systems, by contrast, increasingly adopt a multidimensional approach, the nutritional geometry framework, that distinguishes specific nutrients and calories. We provide evidence that a nutritional approach is likewise relevant to marine apex predators, then demonstrate how nutritional geometry can characterize the nutrient and energy content of marine prey. Next, we show how this framework can be used to reconceptualize ecological interactions via the ecological niche concept, and close with a consideration of its application to problems in marine predator research.

Globally, children are exposed to multiple health risks associated with diet and nutrition. Rather than simply being a condition of having too much or too little food, malnutrition is more a syndrome comprising multiple burdens of coexisting and reciprocal malnutrition, infection, or other conditions. Importantly, children with such syndromes (e.g., stunting and anemia, which are neither specific nor necessarily sensitive to nutritional status) are more likely to also have irreversible functional outcomes such as poor growth, impaired immune function, or cognitive delays. The global health community has identified nutrition-related targets (e.g., Sustainable Development Goals (SDGs) and World Health Organization (WHO) Global Nutrition Targets) that, for multiple reasons, are difficult to address. Moreover, as the complexity of the global health context increases with persistent pandemics of infectious diseases and the rising prevalence of noncommunicable diseases, there is a growing appreciation that conditions selected as nutrition/health targets indeed represent syndromes for which nutritional status serves as both an input and outcome. In recognition of the impact of these combined challenges and the role of the multiple manifestations of malnutrition, we suggest an approach to nutritional assessment that is intended to improve the precision of context-specific, equitable approaches to health promotion, disease prevention, and treatment.

Momos, a delicacy that originated in the Himalayas, have succeeded in crossing cultural barriers and becoming a favourite all over the world. Traditional momos, on the other hand, are made predominantly with refined wheat flour, which is deficient in terms of nutritional richness. The purpose of this article is to investigate the possibility of developing millet-enriched momos by including millet flour into the dough in order to improve in terms of both nutrition and sustainability. In this research, the practicality and consumer acceptability of millet-enriched momos are evaluated via rigorous experimental and sensory analysis. Additionally, insights into the nutritional advantages and ecological implications of these momos are provided.

Since ancient times, locusts have been serious pests wreaking havoc on settled agriculture throughout much of the world. Numerous locust practices have been developed to control infestations. This has led to most commentaries portraying locust infestations only in a negative light while focusing on finding best management practices for suppressing locust populations and lessening crop damage caused by swarms. Yet, locusts are also of great ecological significance in being not only an extraordinary natural phenomenon but also major components of ecosystem nutrient cycling, arising long before settled agriculture. Furthermore, for humans, locusts are a nutritious food source, historically and currently being consumed directly. Locust control today should more regularly include their harvesting. This is now more feasible, as environmentally friendly biopesticides can be used to replace harmful organic pesticides. We focus here on the ecological significance of locusts by using calculations based on a 1 km2 area of swarming and breeding Desert locusts, Schistocerca gregaria, and show that the huge biomass of locust individuals contributes greatly to ecosystem processes while also having great potential use in human nutrition, especially where there is an urgent need for improved dietary intake and nutrition.

The conversion of high-input agriculture to an agro-ecological approach bring harmony to the environment reducing degraded Agroecosystems. The objective of this study was to evaluate the effect of different nutritional management on yield and internal and external quality of tomato fruits as an alternative to the reduction of mineral fertilizers. The research was carried out at the National Institute of Agricultural Sciences (INCA) in Cuba, from September 15 to November 30, 2016. A randomized block design with four replications was used to study four treatments: Absolute control (without mineral fertilizer and bioproducts), Partial ecological nutrition (50 % of mineral fertilizer + bioproducts: mycorrhiza and biostimulant), Organic nutrition (organic fertilizer + bioproducts: mycorrhiza and biostimulant), and Conventional nutrition (NPK mineral fertilizer only). Evaluations regarding agricultural yield and its components, bromatological quality of fruits (Brix, acidity, vitamin C content, and nitrates) and postharvest indices (fruit firmness and diameter of endocarp and mesocarp) were performed. Agricultural yield (25.31 t/ha) and the internal quality of fruits (5.23 °Brix; 11.75 SST; 73.29 nitrates; 18.54 vitamin C, and 4.45 dry matter) applying the treatment where 50% of mineral fertilization was dispensed and complemented by bioproducts did not show significant differences with NPK treatment. Regarding the organic variant, the result in agricultural yield was lower (19.42 t/ha), in comparison with control and the ecological variant. Therefore, it is suggested further evaluation of the effect of the reduction of mineral fertilization on tomato crop and its combination with bioproducts.

Purpose Over the last few decades, consumers’ concerns for healthier lifestyles and the environment have become the driving forces for forming food-buying intentions. The purpose of this paper is to investigate the impact of product attributes regarding nutrition and health benefits of products, the environmental impact of production and social responsibility of producers on consumers’ food and wine choices. Design/methodology/approach The empirical analysis is based on an online survey conducted in the USA, the UK and Germany, and incorporates a discrete choice experiment with visual shelf simulations. Findings Price and nutrition information are much more influential on consumers’ food choices than information about social responsibility of producers or the ecological impact of production. Product attributes emphasizing the ecological impact of production and social responsibility of food producers are specifically valued by consumers with high levels of environmental consciousness and by those concerned about goods production. Consumers who are health conscious regarding their lifestyle and diets derive high utility values from the nutritional information of the product. Practical implications The study contributes to an understanding of how to promote healthier food and wine choices and social and environmental responsibility of food and wine producers in various markets. Originality/value The study offers a comparison of product attributes concerning ecological, social, nutrition and health benefits of the product; as well the investigation of congruent interrelationships between the consumers’ values and related product attributes in three culturally distinct consumer groups.

In Education for Sustainable Development, the topic of sustainable nutrition offers an excellent learning topic as it combines the five dimensions of health, environment, economy, society, and culture, unlike most topics with a regional-global scope. The identification of existing students’ conceptions of this topic is important for the development of effective teaching and learning arrangements. This study aimed to understand students’ conceptions of sustainable nutrition and the relevance that students attribute to the five dimensions. For this purpose, we conducted semi-structured individual interviews with 10th-grade students at secondary schools in Germany (n = 46; female = 47.8%; MAge = 15.59, SD = 0.78). We found that the health dimension prevailed in students’ conceptions of sustainable nutrition; however, the more dimensions the students considered, the less importance was attached to the health dimension. The ecological dimension, in turn, became more prominent as the students’ conceptions became more elaborate. Many students neglected the social, economic, and especially the cultural dimensions. Furthermore, alternative conceptions of the terminology of sustainable nutrition, which did not correspond to the scientific concept, were identified. Students had difficulties linking the ecological, social, economic, and cultural dimensions to sustainable nutrition due to a predominant egocentric perspective on nutrition, which primarily entails focusing on one’s own body.

Understanding the hierarchy for consumers between different labels signaling various characteristics defining food sustainability is still an open question. A web survey was conducted in France to examine how providing different scores about the environment and/or nutrition could influence purchase intents for one pizza. 1200 participants were recruited in France in April 2021. They were asked about their purchase intents for one pizza, before and after seeing nutritional and/or ecological scores associated with colors going from green to red. A Global-Score synthetizing both nutritional and ecological dimensions was also tested. The results show that the appearance of scores and colors significantly affect the purchase intents for this pizza. Indeed, for each type of score (namely nutritional, ecological or global), the dominant effect comes from the reduction in purchase intents related to the red color, although green or yellow colors also change purchase intents but to a lesser extent. With the red color, the nutritional score leads to more significant decreases in purchasing intents than the ones related to the ecological score or the Global-Score. With an additional round, the appearance of another score complementing the alternative one underlines that the negative impact of the red color for one score on purchase intents is not outweighed by the positive impact of the green color for the other score.

The niche concept is central to ecology but is often depicted descriptively through observing associations between organisms and habitats. Here, we argue for the importance of mechanistically modelling niches based on functional traits of organisms and explore the possibilities for achieving this through the integration of three theoretical frameworks: biophysical ecology (BE), the geometric framework for nutrition (GF) and dynamic energy budget (DEB) models. These three frameworks are fundamentally based on the conservation laws of thermodynamics, describing energy and mass balance at the level of the individual and capturing the prodigious predictive power of the concepts of ‘homeostasis’ and ‘evolutionary fitness’. BE and the GF provide mechanistic multi-dimensional depictions of climatic and nutritional niches, respectively, providing a foundation for linking organismal traits (morphology, physiology, behaviour) with habitat characteristics. In turn, they provide driving inputs and cost functions for mass/energy allocation within the individual as determined by DEB models. We show how integration of the three frameworks permits calculation of activity constraints, vital rates (survival, development, growth, reproduction) and ultimately population growth rates and species distributions. When integrated with contemporary niche theory, functional trait niche models hold great promise for tackling major questions in ecology and evolutionary biology.

Poor nutritional behaviour among students is the increasing of snacking proportion and the consumption unnutritious and unsafe food. The aims of the study was to know the determinants of school children's snack behavior using behavioural ecological model. This was a cross-sectional study design based on ecological models behaviour. The study was conducted at a state junior high school in Sleman Regency, D.I Yogyakarta. The sample was 80 students of 381 students. The data were analyzed by the chi-square test. The result showed that only 52.5% students had selected behaviour in snacking, 50% students had a good level of knowledge about nutrition and food security, 68.8% had a large amount of pocket money, 83.8% had breakfast habit, 70% were highly influenced by peers. There were significant relations between knowledge about nutrition and food security and breakfast habits. There were no significant relations between the amount of pocket money, peers with students' behaviour to the selection of snacks in the State Junior High School in Sleman, Special Region Yogyakarta. It is recommended for schools to strengthen their school health institutions through increasing the role of student cadres and counseling about nutrition and food safety in the provision of healthy canteens. Include content about nutrition and the consequences of consuming unsafe food, placing posters on healthy and unhealthy food in the school canteen. Schools are also advised to provide socialization to parents and students about the importance of having breakfast and bringing lunch from home.

European wild rabbit (Oryctolagus cuniculus) has been defined as a keystone species in the Mediterranean ecosystem. Rabbits have been classed as “endangered” by the IUCN within their native range. In this sense, animal nutrition may play a fundamental and limiting role in the conservation of wild species. The overarching goal of ecological nutrition is to unravel the extensive web of nutritional links that direct animals in their interactions with their ecological environments. The main aim of this work was to evaluate the effect of different feed intake, geographic location, animal sex, and reproductive stage on glucose, non-esterified fatty acids (NEFA), and plasmatic urea nitrogen (PUN), albumin, glutamate, and total protein metabolites. Additionally, we examined the potential of these metabolites as biomarkers. Full stomach contents and blood samples were collected from European wild rabbits (n = 89) for the analysis of the metabolites described above. Our work shows that the levels of these metabolites are affected by the sex of the animals, as well as by their reproductive stage (glucose, NEFA and albumin). There were signs of better optimisation of resources by females than by other groups of animals. These data may be interesting in the study of nutritional components that could be affecting physiological state of this species.

This study evaluated the social and ecological factors that affect entomophagy in Ghana with a view to instigate the initiation of programmes for the use of insects for human and poultry nutrition in Africa. Two thousand questionnaires were administered to randomly selected respondents in all the ten regions of Ghana. With regards to social factors, entomophagy was found to be influenced by age, gender, education and occupation. Entomophagy is practiced across all age groups and gender in Ghana. Proportionally, 90, 78 and 74% of the aged (60+), middle aged (31-50) and the youth (18-30), respectively, were observed to consume various insect species. Ecologically, entomophagy was more pronounced in rural than urban areas. Over 87% of respondents who consume edible insects acquire them through harvesting/trapping. Four insect species were identified as feed for animals. The majority (81.6%) of the respondents consume insects as a source of protein, 9.6% for cultural reasons, 5.6% for medicinal values and 3.0 and 0.2%, respectively, for recreational and religious reasons. Gender has the least influence on entomophagy. Considering the economic, ecological and nutritional importance of edible insects in traditional Ghanaian foods, attention should be given to sustainable environmental harvesting practices.

Access to adequate and nutritious food is important for the current and future health of adolescent girls. Interventions often focus on the individual as responsible for their own health ignoring the complex structural issues that underlie optimal nutrition. In South Asia gender inequalities have been noted as an important determinant of poor nutrition among women and their young children, but analysis of adolescent girls’ diets and what influences these are rarely undertaken. Therefore, we sought to analyse the factors affecting what and where girls’ eat and what affects their behaviour in the plains of Nepal, using a cultural-ecological approach. We analysed a secondary qualitative dataset of focus group discussions with adolescent girls aged 12–19 years old, young mothers, mothers-in-law, and older female key informants. Eating was heavily influenced by patriarchal norms. Boys had preferential access to food, money, and freedom of movement to appreciate their future role in providing for the family. Food was an investment, and boys were perceived to have more nutritional need than girls. Girls were not perceived to be a good return on investment of food, and eating practices sought to prepare them for life as a subservient daughter-in-law and wife. Obedience and sacrifice were valued in girls, and they were expected to eat less and do more housework than boys. Girls’ eating and behaviour was constrained to maintain self and family honour. Interventions should acknowledge cultural influences on eating and engage multiple actors in addressing harmful gender norms which limit eating and prevent girls from reaching their potential.

Childhood overweight and obesity has been a significant public health concern in the United States for decades. School-based obesity prevention programs have been one strategy to address this issue. This article describes the implementation of a knowledge-based, healthy eating intervention delivered to 4th and 5th graders in a southern California school district. Trained graduate students implemented a nutrition education curriculum, consisting of three monthly lessons that would eventually be utilized and sustained by the schools’ Physical Education (PE) teachers in the following school year. As such, the intervention drew upon the Social Ecological Model (SEM) to describe how nutrition education could be implemented in a sustainable way to future generations of youth. Students were assessed on their knowledge and dietary behaviors at pre-test and after the final lesson. Students’ overall nutritional knowledge significantly increased from pre-test to post-test; however their self-reported eating behaviors (e.g., low fruit and vegetable consumption, and high consumption of chips, soda, and sweets) largely remained the same. Although the findings of this study were largely non-significant, we conclude that future interventions, which creatively address different levels of the target population’s environment, may have promise if they are sufficiently dosed.

There is much debate on the reasons for the poor nutritional status of the population amidst high economic growth in the country. A profusion of correlations and statistical averages characterizes mainstream nutritional discourses that are based on the notion of food as a thing that could be measured and understood in terms of numerical values. Much as the quantitative approach is necessary to guide public policy and to provide the basic food security to the population, it is a partial view, not adequate to understand the issues surrounding nutrition in all its dimensions. Drawing upon field data on food in rural South India, this article calls for a broader perspective on food that gives scope for people’s concerns about its quality and ecological source. It aims at providing a sociologically informed understanding of the statistical and the existential aspects of the nutrition problem.

Sustainability is to meet the needs of today's conditions by preserving the quality and existence of the resources that future generations need. In this study, we aimed to discuss the ecological effects of sustainable nutrition, its role in food systems and its importance during the COVID-19 pandemic. Method: This review study was prepared in line with the data obtained from research on sustainable nutrition and sustainable food systems during the COVID-19 pandemic. Results: Misuse of resources, while changing food systems; The increase in greenhouse gas emissions causes environmental problems such as the destruction of lands and the depletion of water resources, increasing the ecological, carbon and water footprint. Sustainable nutrition system, on the other hand, refers to a diet with low ecological impacts that provides food security for present and future generations. At the same time, sustainable nutrition; aims to minimize the consumption of high-energy, processed and packaged products, and to consume less animal-based and more plant-based foods. With the Sustainable Development Goals determined by the United Nations, it is aimed to ensure food security, end hunger and improve nutrition until 2030. But the COVID-19 pandemic seriously jeopardizes the ability to achieve many of these goals. Conclusion: Sustainable food systems during the pandemic require various food production supports and innovative interventions including food safety. It should not be ignored that the determined policies should have not only local but also global effects.

Abstract Who are the peasants/Indigenous people and what is their role in the history and future of Mexico? Questioning the dominant version of the socio-political dynamics, I start with corn, a grain created in Mesoamerica, to develop one of most admired agroecological systems in the world. It contributes to good nutrition and health, (re)shaping social structures and the territory itself. Today’s communities, transformed into a Communitarian Revolutionary Subject provide a model for post-capitalist societies. I apply the framework of Radical Ecological Economics to illustrate and accompany this dynamic.

We have evaluated the effect of early and late micro-ecological enteral nutrition on systemic inflammatory response, bacterial translocation, and immune function in patients with severe acute pancreatitis. Two weeks after treatment, experimental group receiving early nutritional intervention exhibited a significant increase in intestinal lactobacilli and bifidobacteria, fewer staphylococci, and E. coli, and lower levels of serum endotoxin, D-lactic acid, and diamine oxidase than the group receiving late intervention (control group) (P < 0.05). Also, the serum levels of CD3+ and CD4+ and CD4+/CD8+ ratio significantly increase after 2 weeks of intervention. On the other hand, the level of CD8+ and the Acute Physiology and Chronic Health Evaluation II and Modified Computed Tomography Severity Index scores significantly decreased after 2 weeks of treatment (P < 0.05). The early intervention also led to a significant shortening of time needed for abdominal pain relief, anal exhaustion, resumption of peristaltic sound, and hospitalization. Furthermore, there was a significant increase in overall response rate, and decrease in the incidence rate of complications (P < 0.05). Early micro-ecological enteral nutrition therapy can effectively relieve systemic inflammatory response, prevent intestinal bacterial translocation, restore the function of intestinal mucosal barrier, and alleviate nutritional imbalance in severe acute pancreatitis patients leading to improved immune function, mitigation of the disease, and reduced complications benefiting the recovery of patients.

Animal populations are regulated by the combined effects of top-down, bottom-up and abiotic processes. Ecologists have struggled to isolate these mechanisms because their effects on prey behaviour, nutrition, security and fitness are often interrelated. We monitored how forage, non-consumptive effects (NCEs), consumptive predation and climatic conditions influenced the demography and nutritional state of a wild prey population during predator recolonization. Combined measures of nutrition, survival and population growth reveal that predators imposed strong effects on the prey population through interacting non-consumptive and consumptive effects, and forage mechanisms. Predation was directly responsible for adult survival, while declining recruitment was attributed to predation risk-sensitive foraging, manifested in poor female nutrition and juvenile recruitment. Substituting nutritional state into the recruitment model through a shared term reveals that predation risk-sensitive foraging was nearly twice as influential as summer forage conditions. Our findings provide a novel, mechanistic insight into the complex means by which predators and forage conditions affect prey populations, and point to a need for more ecological studies that integrate behaviour, nutrition and demography. This line of inquiry can provide further insight into how NCEs interactively contribute to the dynamics of terrestrial prey populations; particularly, how predation risk-sensitive foraging has the potential to stabilize predator–prey coexistence.

AbstractObjectiveTo show that nutrition science is anchored in food systems and is influenced by the social, through the environmental to the cosmological, life's connections and rhythms. To indicate that an integrative approach is now becoming possible with advances in food technology, in the understanding of food choice and of human behaviour, and in a preparedness to recognise nutritional inputs in the full sweep of life-long well-being and health outcomes.MethodAn analysis of the much broader understanding of nutritionally related diseases from an ecological perspective, with attention to economic development, beginning with poverty alleviation. Recognition that the biological dimension of nutrition science is undergoing a profound reappraisal; that technologies will allow us to change the course of nutritionally related diseases for the better; and that nutrition science will find partners in information technology and telecommunications, food technology and energy technology.ConclusionA new generation of nutrition scientists can help build a new economy that supports development amongst communities, whether close or distant from each other. The opportunities for this kind of development to be realised between Asia, Latin America and Africa are considerable. At all times, however, nutrition scientists must uphold the paramount importance of good governance, conflict resolution and maternal literacy if their work is to achieve its growing potential.

This study sought to elucidate the multi-level factors that influence behaviors underlying high childhood stunting and widespread micronutrient deficiencies in Kiribati. This two-phase formative research study had an emergent and iterative design using the socio-ecological model as the guiding theoretical framework. Phase 1 was exploratory while phase 2 was confirmatory. In phase 1, in-depth interviews, free lists, seasonal food availability calendar workshops, and household observations were conducted. In phase 2, focus group discussions, pile sorts, participatory workshops, and repeat observations of the same households were completed. Textual data were analyzed using NVivo software; ethnographic data were analyzed with Anthropac software for cultural domain analysis. We found a combination of interrelated structural, community, interpersonal, and individual-level factors contributing to the early child nutrition situation in Kiribati. Despite widespread knowledge of nutritious young child foods among community members, households make dietary decisions based not only on food availability and access, but also longstanding traditions and social norms. Diarrheal disease is the most salient young child illness, attributable to unsanitary environments and sub-optimal water, sanitation, and hygiene behaviors. This research underscores the importance of a multi-pronged approach to most effectively address the interrelated policy, community, interpersonal, and individual-level determinants of infant and young child nutrition in Kiribati.

Agricultural interventions more effectively improve nutrition when they are adapted to local contexts and engage multiple sectors. However, evidence is limited for how to design and measure the impacts of such interventions. We piloted a participatory methodology to collect community feedback to inform the design and selection of measures for a multisector nutrition intervention in Ethiopia. Study participants were purposively recruited from 6 rural districts in Tigray and the Southern Nations, Nationalities, and Peoples’ regions. Qualitative data were collected from 12 focus group discussions with smallholder farmers (men and women) participating in a nutrition-sensitive agriculture intervention. The Sustainable Livelihoods Approach (SLA) combined with an ecological systems model informed the survey tool and analyses. Analyses revealed 3 key findings. First, there were regional differences in how communities defined assets important for nutrition. Second, when asked to prioritize which assets were most important, communities selected every SLA capital category; however, the types of assets within each category differed by region. Third, the most commonly reported barriers to good nutrition were traditional feeding behaviors (eg, men eating before women) and lack of nutrition knowledge. How households use assets to enhance nutrition is influenced by diverse and dynamic cultural, social, economic, and ecological factors. The participatory methods piloted in this study present a novel approach to identify contextually relevant household, community, and institutional assets used to support food and nutrition security.

Unequal economic growth shapes food systems. Nutrition problems incorporate inappropriate practices, so nutrition education is key to empowering consumers to choose healthy foods. However, increasing the accessibility of healthy diets is related to reducing the cost of nutritious foods. The accounting management of healthy nutrition should allow for optimal global decision-making. The evolution of scientific production and global research trends on this topic between 1968 and 2019 have been studied. Statistical and mathematical methods have been applied to 1738 documents from the Scopus database. The results provided data on the agents that participate in the development of the theme. Data reveal an exponential trend, especially in the previous decade, with more than 50% of scientific production. Future lines of research have been identified: investment in health systems; green label education; early impact of food insecurity; WIC (Women, Infants, and Children) nutrition education; food waste audit; and ecological footprint of food. The central contribution of the study has been to detect the main future directions of research, providing critical points that will allow us to identify the themes of future publications, in addition to providing an instrument for decision-making carried out by the research funding sponsors.

The complex interaction between social, economic, and environmental processes coupled with transformations of the landscape primarily driven by urbanization have impacts on the access, availability, and distribution, of food. This has resulted in a global micronutrient deficiency and hunger. Given rapid urbanization and population growth, a more sustainable food system is necessary to feed more urban populations and provide adequate nutrition, especially in developing countries. Existing frameworks for modelling urban-environment interactions contain components related to food security, however, lack the specificity needed to evaluate the effects of land use decisions and agricultural production strategies on the health of local populations measured through metrics such as nutritional output. The research presented here proposes an urban nutrition (UN) extension to the previously published urban ecological economic system by developing a focused component that simulates scenarios of different degrees of urbanization and agricultural production techniques to improve the nutritional output of agricultural land, while considering the conservation of soil. This simulation approach was subsequently applied to the Toluca Metropolitan Zone, Mexico. Results showed that nutritional output would greatly increase when adding a variety of crops, even in scenarios where agricultural land is limited. The proposed extension can be used by decision makers worldwide to evaluate how landscape configurations and agricultural production systems affect the nutritional needs of the local population while fostering sustainable practices.

The European wild rabbit (Oryctolagus cuniculus) plays an important ecological role in the ecosystems of the Iberian Peninsula. Recently, rabbit populations have drastically reduced, so the species is now considered endangered. However, in some places, this animal is considered a pest. This is the conservation paradox of the 21st century: the wild rabbit is both an invasive alien and an endangered native species. The authors of this review aimed to understand the keys to the adaptive success of European rabbits, addressing all aspects of their biology in order to provide the keys to the ecological management of this species. Aspects including nutrition, genetics, immunity interactions with the environment, behaviour, and conflict with human activities were reviewed. Ultimately, rabbits are resilient and adaptable. The main adaptations that explain the rabbit’s adaptive success are its nutrition (wide adaptation to food and good nutritional use of caecotrophy), immune system (powerful and developed), and other aspects related to genetics and behaviour. Rabbits’ relationship with humans has led them to colonise other places where they have become pests. Despite these adaptations, populations in native places have been drastically reduced in recent years. Since it serves as a bastion of the Mediterranean ecosystem, a specific conservation program for this species must be carried out. Therefore, a study of the rabbit’s response to diseases and nutrition (especially protein), as well as the interaction between them, is of special interest.
