Natural bioactive compounds found in Momordica charantia including polysaccharides, saponins, polyphenols, alkaloids, and notably polypeptide-p (often referred to as “plant insulin”)—have shown promising potential in shaping nutritional and therapeutic strategies for managing diabetes, metabolic disorders, and other nutrition-related diseases. Both retrospective and prospective analyses of bitter gourd’s functional properties such as its antioxidant, antitumor, immunomodulatory, and antibacterial effects highlight its innovative use as a food ingredient in developing targeted nutritional therapies. Assessing its applicability in the food industry, particularly through the fortification of products with bitter gourd powders, pulp, juice, or extracts, could enhance consumer acceptance and elevate the perceived quality of nutritionally superior foods. The nutrifunctional attributes revealed by its nutritional profile support the strategic integration of bitter gourd into various food formulations, contributing to a broader and more diverse range of dietary options. This diversification is especially valuable in addressing the dietary monotony often associated with diabetic nutrition plans, which continue to present significant challenges. The foundation laid by this review drawing on both theoretical insights and practical applications serves as a springboard for future research into the fortifying potential of bitter gourd-based preparations. Ultimately, such products may be recommended not only as nutritional supplements but also as part of clinical and hygienic-dietetic practices. Full article

Camelina sativa (CS) is an emerging sustainable oilseed crop with interesting feed application potentialities. The research assessed the potentiality of Camelina sativa (CS) in the diet for free-range laying hens, aiming at reaching a nutritional claim. To this purpose, two feeding groups of hens (n = 100 Livorno hens, n = 25 hens/pen) were farmed outdoor and received either a Control diet, which was a commercial diet for laying hens, or a CS diet. The latter was formulated to include the 5% CS cake and 1% CS oil, replacing conventional feedstuffs. Diets were isoprotein and isoenergy and were available ad libitum throughout the laying period (February–September). At day 1, n = 12 eggs/diet were sampled to assess the initial proximate composition and FA profile. Every 7 days the sampling was repeated to analyze the eggs’ FA profile, up to day 35. At the end of the laying season, n = 6 hens/dietary treatment were slaughtered and subjected to meat quality evaluations. Results highlighted that a 28-day feeding was the period required to obtain 227 mg of C18:3 n-3 and 81 mg of C20:5 n-3 + C22:6 n-3/100 g egg, whereas a further 7 days of feeding trial were ineffective in further enhancing the omega-3 FA content of eggs. CS eggs were comparable to Control ones for overall physical traits, proximate composition, and shelf-life. In addition, at the end of the laying period, the meat of CS hens was also found to be healthier than that of Control ones, thanks to a higher omega-3 FA proportion (p < 0.01), which was, however, not sufficient to reach any nutritional claim. Instead, the proximate composition of CS meat was overall comparable to Control hens. In conclusion, the present research demonstrated that feeding Camelina sativa meal and oil to laying hens is feasible and allows to reach the nutritional claim in eggs “rich in omega-3 FA” after a feeding period of 28 days, without any negative effects on other eggs’ quality trials. Camelina sativa can thus be defined as a promising sustainable feedstuff for the poultry sector for diversification purposes and to enhance the nutritional quality of eggs. Full article

The diversification of plant protein sources is a strategic priority for European food systems, particularly under the EU Green Deal and Farm to Fork strategies. In this study, dual production of full-fat soy (FFS) and expanded soybean cake (ESC) was evaluated using non-GMO soybeans cultivated under semi-organic conditions in Central Poland. Two agronomic systems—post-emergence mechanical weeding with rotary harrow weed control (P1) and conventional herbicide-based control (P2)—were compared over a four-year period. The P1 system produced consistently higher yields (e.g., 35.6 dt/ha in 2024 vs. 33.4 dt/ha in P2) and larger seed size (TSW: up to 223 g). Barothermal and press-assisted processing yielded FFS with protein content of 32.4–34.5% and oil content of 20.8–22.4%, while ESC exhibited enhanced characteristics: higher protein (37.4–39.0%), lower oil (11.6–13.3%), and elevated dietary fiber (15.8–16.3%). ESC also showed reduced anti-nutritional factors (e.g., trypsin inhibitors and phytic acid) and remained microbiologically and oxidatively stable over six months. The semi-organic P1 system offers a scalable, low-input approach to local soy production, while the dual-product model supports circular, zero-waste protein systems aligned with EU sustainability targets.

Rice is one of the most important staple foods worldwide. Asia, particularly South and Southeast Asia, is a major rice producer, and rice production is also gradually increasing in Africa. However, rice cultivation poses economic and environmental challenges, which are exacerbated by climate change. Hence, diversification of rice-based production systems is highly imperative to improve soil health and thus sustain productivity while also enhancing income opportunities. Vegetables and pulses are crucial components for diversifying rice-based production systems as they have the potential to increase income and improve soil health. The World Vegetable Center has introduced mungbeans and vegetable soybeans to diversify the cereal-based production systems in Asia. About 27–93% of the mungbean area in India, Pakistan, Bangladesh, and Myanmar is planted with varieties containing improved germplasm developed by WorldVeg in collaboration with national agricultural research systems. Additionally, the introduction of vegetables and legumes is highly remunerative and improves dietary diversity, leading to better nutrition. For instance, the productivity of vegetable crops increased by 200–350% when they were combined with improved production practices. Such diversification also holds great promise for improving income and nutrition in Africa. It also enhances the resilience of farming systems, particularly in a changing climate. Hence, governments should prioritize system diversification to enhance the income and livelihood opportunities for smallholders in Asia and Africa. Full article

The objective of this work was to explore the effect of taxonomically and phytochemically rich swards, as opposed to ‘status quo’ monoculture of ryegrass and white clover swards, on animals and milk, by assessing the metabolomic profile of plant and milk samples. The results of this study suggest that metabolomic profiles and metabolism are altered by dietary diversity and grazing management. Several metabolites associated with enhanced consumer health were elevated in milk from cows that were grazed in functionally diverse swards as opposed to monoculture of ryegrass and white clover swards. The results show the value of metabolomics for the identification of metabolites associated with a ‘pasture-fed diet’, which is considered beneficial to human health compared with grain-fed milk products. Metabolomics also provide evidence that grazing management and the presence of key forages may be more beneficial for market differentiation of milk products that can enhance consumer health than maximisation of sward species diversification.

Background/Objectives: Child undernutrition remains a critical public health issue in Nepal, especially in the rural district of Solukhumbu. This study aimed to assess the prevalence and clinical characteristics of undernutrition, dietary patterns, and related health indicators in school-aged children from the Shree Saraswoti Basic School in Phuleli. Methods: A descriptive, cross-sectional study was conducted between July and August 2022. Fifty-four children (51.8% boys; mean age 9.4 ± 2.1 years) were evaluated using anthropometry, clinical examination, hemoglobin measurement, and three-day 24 h dietary recall. Data were analyzed using descriptive and inferential statistics. Results: BMI z-scores indicated that 39% of children were at risk of acute undernutrition, and 2% were at risk of moderate acute undernutrition. After adjusting for altitude, 87% were classified as anemic. Diets were dominated by cereals and vegetables, with a very low intake of fruits and proteins and no dairy consumption. Dental caries affected 59% of participants. Girls presented slightly higher subcutaneous fat percentages; however, 14.8% of the children exceeded the recommended thresholds. A dietary assessment revealed poor eating habits, including excessive intake of simple carbohydrates and insufficient nutrient diversity. Although socioeconomic data were not directly collected, the findings reflect the typical context of the vulnerability of isolated mountain communities. Undernutrition indicators (BMI, clinical signs, anemia) were associated with poorer health outcomes. An unexpected moderate inverse correlation was found between BMI and both systolic (r = −0.601) and diastolic (r = −0.550) blood pressure. Conclusions: The findings reveal a high burden of undernutrition and anemia among children in Solukhumbu, linked to poor diet and structural vulnerability. Urgent, community-based interventions—including nutrition education, agricultural diversification, and improved healthcare access—are needed. Longitudinal monitoring is essential to track progress and design sustainable, multisectoral solutions. Full article

As symbiotic mycorrhizal associates, species within the genus Laccaria play pivotal roles in forest ecosystems, specifically forming ectomycorrhizal relationships with the root systems of various plants. Some Laccaria species are recognized for their edibility, holding potential as a sustainable food source in the context of future food security and dietary diversification. In this study, the species diversity of Laccaria in Yunnan was investigated, and four novel species were identified. Their taxonomical positions and phylogenetic affinities were confirmed through phylogenetic analysis based on ITS, nrLSU, tef1-α, and rpb2 sequence data. Macro- and micro-morphological characteristics of the new species are also given here. Laccaria brownii sp. nov. has a dark to slightly desaturated orange pileus, stipe context broadly fistulose and soft orange, and relatively smaller cheilocystidia and pleurocystidia. Laccaria orangei sp. nov. has a hemispherical to paraboloid pileus, abundant narrowly clavate, flexuose, and branched cheilocystidia. Laccaria ruber sp. nov. pileus is red on the margin, clearly striate on the pileus surface, basidia clavate, mostly four-spored, rarely two-spored. Laccaria stipalba sp. nov. stipe surface is white, long sterigmata (4–13 μm × 2–3 μm), pleurocystidia narrowly clavate to subclavate, flexuose or mucronate, rarely branch. The descriptions, illustrations, and phylogenetic analysis results of the new taxa are provided. In addition, the new taxa are compared with closely related taxa. Full article

Microgreens are tender, edible seedlings harvested 7–21 days after germination containing a central stem, cotyledons, and true leaves. Known as a fresh, ready-to-eat functional food, they are mostly rich in vitamins, antioxidants, bioactive compounds, and minerals, with distinctive flavors, colors, and textures. These attributes make microgreens a valuable component in nutrition and health research. In countries like India, where low-income households spend 50–80% of their income on food, micronutrient deficiencies are common, particularly among women. Indian women, facing a double burden of malnutrition, experience both underweight (18.7%) and obesity (24.0%) issues, with 57% suffering from anemia. Women’s unique health requirements vary across life stages, from infancy to their elderly years, and they require diets rich in vitamins and minerals to ensure micronutrient adequacy. Microgreens, with their high nutrient density, hold promise in addressing these deficiencies. Fresh and processed microgreens based products can enhance food variety, nutritive value, and appeal. Rethinking agriculture and horticulture as tools to combat malnutrition and reduce the risk of non-communicable diseases (NCDs) is vital for achieving nutritional security and poverty reduction. This review compiles recent research on microgreens, focusing on their nutrient profiles, health benefits, suitable crops, substrates, seed density, growing methods, sensory characteristics, and applications as fresh and value-added products. It offers valuable insights into sustainable agriculture and the role of microgreens in enhancing human nutrition and health. Full article

The development of plant-based meat substitutes is imperative for reducing animal fat intake and promoting dietary diversification. However, the flavor profiles of these products frequently fall short of consumer expectations. This study sought to optimize the production process of meat flavorings for plant-based products using the Taguchi method. The study investigated the effects of sugar type, concentration, and reaction temperature on the Maillard reaction products, sensory characteristics, and volatile organic compounds. The thermal process flavors were obtained from the flavor precursor by heating in a laboratory microwave station at 30 bar for 15 min. The variable factors were the type of sugar (fructose, glucose, xylose), its concentration (25, 50, and 100 mM), and the temperature of the reaction (140, 150, and 160 °C). The study’s findings indicated that temperature emerged as the predominant factor influencing the formation of Maillard reaction products and the sensory characteristics of the flavorings. Specifically, 25 mM xylose-based flavorings prepared at 140 °C demonstrated the most notable meat flavor and the highest level of acceptability. Moreover, the analysis of volatile organic compounds revealed the presence of a diverse array of substances, including aldehydes, ketones, and alcohols, that are characteristic of meat flavor. A heat map of the volatile content was constructed to facilitate a comparison of the samples. The study demonstrates the effectiveness of the Taguchi method in optimizing the production process of meat flavorings for plant-based products and provides valuable insights for the development of more balanced odor profiles.

The socio-political climate in the UK, compounded by government austerity measures, has intensified the cost-of-living crisis, significantly impacting the affordability of the food supply chain. This has led to an increasing disconnect from healthy dietary practices and has contributed to declines in mental and physical wellbeing. This paper examines the role of edible city (EC) initiatives in addressing these challenges by enhancing food security, fostering social resilience and supporting community wellbeing. The aim of this research is to understand the tangible links between EC mechanisms and how they align with local, cultural and geographical perspectives. Focusing on the City of Lincoln, UK, this study aims to develop a contextualised EC framework that is culturally and geographically relevant and aligns with global goals for sustainable urban development as outlined in the United Nation’s Sustainable Development Goal 11 (SDG11), promoting inclusive, environmentally safe and economically viable communities. Utilising a mixed methods approach, this research combines qualitative interviews and a critical cross-case analysis of four community growing groups in the UK, alongside quantitative socio-demographic data analysis. The findings reveal that successful EC initiatives adapt to their environment and socio-cultural conditions and highlight the importance of EC diversification for long-term sustainability. Four core themes emerged across the case studies: (1) social prescribing, (2) social capital (3) knowledge sharing and (4) social value. These findings inform the creation of a novel flexible EC framework, Lincoln, providing actionable insights and policy recommendations to support sustainable urban regeneration and enhance community resilience. This research contributes transferable knowledge to inform EC strategies across diverse global urban contexts, promoting a pathway toward resilient and socially cohesive urban environments.

Limited information exists on the diet of snow leopards (SL), factors affecting livestock mortality, and local attitudes toward SL conservation in the Manaslu Conservation Area (MCA), Nepal. Therefore, we aim to investigate the dietary preferences of SL, the factors influencing livestock mortality, and local conservation attitudes. From November 2021 to January 2022, 23 SL scats were collected along 24 transects (total length: 21.6 km) in MCA. Camera traps, set within 4 km × 4 km grids at 28 stations for 661 trap nights, were used to assess prey availability. Jacobs’ index calculated prey preference, while a Generalized Linear Mixed Model (GLMM) assessed factors linked to livestock depredation. Additionally, 65 households from two villages were randomly selected in a survey on depredation and conservation attitudes. Scat analysis identified six wild prey species, including pika (Ochotona sp.), Himalayan tahr (Hemitragus jemlahicus), and blue sheep (Pseudois nayaur), as well as three domestic species: ox/cow, yak, and horse. Himalayan tahr had the highest presence in the SL diet (40%). Despite pika having the highest Relative Abundance Index (RAI), SL strongly preferred horses and avoided pika. Larger prey, such as horses, Himalayan tahr, and blue sheep, were highly preferred. Households with more livestock experienced higher depredation rates. Local attitudes toward SL conservation were generally positive, with an average score of 2.59. We recommend an integrated SL conservation plan in MCA, incorporating local participation, income diversification, and employment programs to mitigate conflicts and promote coexistence. Full article

Background and aim: Cereals’ iron content is a major contributor to dietary iron intake in Europe and a potential for biofortification. A simulation of daily iron intake from wheat and rice over the next 20 years will be quantified. Methods: Food items, and energy and iron intake by age classes are estimated using the Italian dietary survey (IV SCAI). Iron intake and adequacy estimation trends were categorized in four scenarios compared to a baseline (basic scenario; only climate change effects): over wheat and rice biofortification effects (scenario 1); over the shift in whole wheat consumption of up to 50% of the total amount of wheat-based foods (scenario 2); over the shift in brown rice consumption up to 100% of the total amount of rice (scenario 3); over the cumulative effects of biofortifications and whole wheat and brown rice consumption (scenario 4). Results: Increasing the iron intake from wheat and rice biofortification and the shift in whole wheat consumption is similar and sufficient to recover the baseline iron depletion effect due to climate change. The shift in brown rice consumption produces a negligible increment in iron intake. The cumulative effects of the corrective actions considered in the scenarios can significantly reduce the iron intake inadequacy, despite not reaching the recommended levels. Conclusions: Corrective actions including biofortification and whole grain consumption are still far from ensuring the full recovery in children and females of fertile age as at-risk groups of iron deficiency. Further actions are needed considering other biofortified food sources, fortified foods, and/or dietary food diversification. Full article

The production of functional foods has aroused growing interest due to its proven health benefits and potential to improve quality of life. One of the products that have gained importance due to its practicality is enriched beverages. Kefir, a fermented beverage traditionally produced from cow’s milk, is cultivated using kefir grains containing a symbiotic culture of bacteria and yeast, which has great nutritional power and benefits the microbiota. In this research, an enriched powdered milk beverage with a high protein content is prepared due to the incorporation of lupine (Lupinus mutabilis), kiwicha (Amaranthus caudatus), and quinoa (Chenopodium quinoa). The beverage prepared shows a 48% increase in protein content compared to commercialized kefir. After the beverage was obtained, it was freeze-dried to preserve its nutritional and functional properties. The resulting beverage, kefir milk powder, enriched with native Andean grains such as lupin, kiwicha, and quinoa, presents a sustainable and nutrient-rich option that contributes to dietary diversification.

Agriculture, a cornerstone of Nepal’s economy, is dominated by smallholder farmers cultivating staple crops under resource and input constraints, leading to declining productivity amid rapid population growth and urban migration. This study explores the role of agricultural diversification in enhancing dietary diversity and improving smallholder livelihoods using panel data from the Nepal Household Risk and Vulnerability Survey (2016–2018). Analysis through the Simpson diversification index and food consumption scores reveals a strong positive correlation between agricultural diversification and dietary diversity. Key determinants include market access, irrigation systems (rainfed or canal-based), input availability (fertilizers and labor), and land type. Dry season crop diversification was positively associated with dietary diversity, while market access showed a significant negative impact on dietary diversity as distance increased. Upland areas exhibited higher potential for diversification, especially in the dry season, driven by improved access to inputs and irrigation. Policy recommendations highlight the need to enhance infrastructure in upland regions, improve market access, and ensure input availability, particularly fertilizers and labor, to support seasonal diversification. Such measures are essential for strengthening food security, nutritional diversity, and economic resilience among smallholder farmers in Nepal. Full article

Malnutrition is a major concern in Madagascar. Eating a wide variety of nutritious food is necessary because Malagasy diets heavily rely on rice consumption. This study explored the barriers to dietary change towards diversification from the perspective of consumer behaviour. We analysed the impact of risk and time preferences on dietary diversity using economic experiments conducted with 539 rural lowland rice farmers in Central Highlands in Madagascar. The results showed that risk-averse or impatient individuals were more likely to have lower Household Dietary Diversity Score (HDDS), indicating poorer diet quality. Risk-averse people may not want to add different foods to meals as they perceive unfamiliar food as a ‘risk’; people who prefer immediate gratification may fail to invest in nutritious diets now to achieve better health in the future. Additionally, higher HDDS was observed among households with a female head who earned off-farm income and who had frequent market visits. These findings contribute to explaining the limited shift in nutritional transition in Madagascar and provide useful insights into nutritional policies promoting healthier food choices. Depending on the preferences, more focused support such as nutritional education, financial support, market development, and pre-commitment mechanisms could be provided to reward long-term nutritional benefits.
