Salinity is a major abiotic stress limiting black gram (Vigna mungo) productivity, particularly in arid and semi-arid regions. Saline soils negatively impact plant growth, nodulation, nitrogen fixation, and yield. This study evaluated the efficacy of co-inoculating salt-tolerant plant growth-promoting bacteria Paenibacillus sp. SPR11 and Bradyrhizobium yuanmingense PR3 on black gram performance under saline field conditions (EC: 8.87 dS m⁻¹; pH: 8.37) with low organic carbon (0.6%) and nutrient deficiencies. In vitro assays demonstrated the biocontrol potential of SPR11, inhibiting Fusarium oxysporum and Macrophomina phaseolina by 76% and 62%, respectively. Germination assays and net house experiments under 300 mM NaCl stress showed that co-inoculation significantly improved physiological traits, including germination rate, root length (61.39%), shoot biomass (59.95%), and nitrogen fixation (52.4%) in nitrogen-free media. Field trials further revealed enhanced stress tolerance markers: chlorophyll content increased by 54.74%, proline by 50.89%, and antioxidant enzyme activities (SOD, CAT, PAL) were significantly upregulated. Electrolyte leakage was reduced by 55.77%, indicating improved membrane stability. Agronomic performance also improved, with co-inoculated plants showing increased root length (7.19%), grain yield (15.55 q ha⁻¹; 77.04% over control), total biomass (26.73 q ha⁻¹; 57.06%), and straw yield (8.18 q ha⁻¹). Pod number, seed count, and seed weight were also enhanced. Nutrient analysis showed elevated uptake of nitrogen, phosphorus, potassium, and key micronutrients (Zn, Fe) in both grain and straw. To the best of our knowledge, this is the very first field-based report demonstrating the synergistic benefits of co-inoculating Paenibacillus sp. SPR11 and Bradyrhizobium yuanmingense PR3 in black gram under saline, nutrient-poor conditions without external nitrogen inputs. The results highlight a sustainable strategy to enhance legume productivity and resilience in salt-affected soils. Full article

Background: The relationship between sports participation and food preferences in adults, as well as the influence of gender, is still unclear. Objective: The objective of this study was to investigate the association between sports participation and individual food preferences and to explore potential gender differences among sports participants in a large group of Italian adults. Methods: This cross-sectional study involved 2665 adults (aged ≥ 18 years) who lead normal lives and underwent a routine lifestyle and dietary assessment at a clinical centre specialising in nutrition, metabolic health, and lifestyle counselling in Rome. Participants completed an online questionnaire on food preferences (19 foods) and sports practice. Multivariate logistic regression models, adjusted for age, sex, and smoking, were used to assess associations. Results: Sports participation was defined as engaging in structured physical activity at least once per week and was reported by 53.5% of subjects (men: 60.1%; women: 49.0%; p < 0.0001). After adjustment, active individuals were significantly more likely to prefer plant-based drinks, low-fat yoghurt, fish, cooked and raw vegetables, fruit, whole grains, tofu, and dark chocolate (all p < 0.05) and less likely to prefer cow’s milk (p = 0.018). Among sport participants, males were more likely to prefer meat (general, white, red, processed) and eggs, while females preferred plant-based drinks. No significant gender differences were observed for dairy products, legumes, or fish. Differences in food preferences were also observed according to the type of sport, with bodybuilders showing higher preference for tofu and dark chocolate. The strongest associations were found in the 25–44 age group. Conclusions: Sports participation is independently associated with specific food preferences, characterised by greater preference for plant-based and fibre-rich foods, and gender differences in food choices persist even among active adults. These findings highlight the need to consider both sports participation and gender when designing nutritional interventions. Full article

The Atlantic Diet (AD) is based on traditional dietary patterns in Galicia (northwestern Spain) and northern Portugal and is known for its health benefits. The AD focuses on fresh, local, and seasonal foods, especially fish, seafood, vegetables, legumes, whole grains, fruit, olive oil, and a moderate consumption of wine. However, it has received less attention from researchers than other dietary patterns. The present study had two main objectives: (i) to evaluate the dietary habits of a Galician population in relation to the AD and (ii) to create a numerical index to measure adherence to the AD. In 2022, a validated food frequency questionnaire was administered to 500 healthy adults living in Galicia. The data on participants’ dietary habits showed notable deviations from the ideal AD, especially regarding consumption of fruits, grains, and seafood. However, an adequate intake of legumes and nuts was observed, along with a reduction in the consumption of processed foods (except among younger participants) relative to that revealed in previous surveys. To assess adherence to the diet, statistical and chemometric analyses were applied, leading to the development of a new index: the Atlantic Diet Scale (ADS). The ADS was compared with three existing tools and proved to be a simple, flexible, and effective method for assessing dietary adherence based on optimal intake levels across food groups. When applied to dietary data, the ADS yielded adherence levels similar to two of the three traditional methods, with some differences relative to the third. These findings highlight the need for standardized evaluation tools, including clear definitions of food groups and consistent scoring systems, to better assess and promote adherence to the Atlantic Diet.

Background/Objectives: Colorectal cancer is a leading cause of cancer-related death worldwide, with rising incidence in younger adults. Unhealthy diets high in red and processed meat and low in fiber are key modifiable risk factors, highlighting the need for preventive nutritional strategies targeting CRC through dietary interventions. Methods: A one-day sample diet for colorectal cancer prevention, consisting of fiber-rich meals excluding red meat and incorporating whole grains, legumes, vegetables, fruits, nuts, and lean protein alternatives (such as fish and poultry), was developed. Its acceptability was assessed in a cross-sectional study using an online questionnaire among healthy Romanian adults aged 18–50, with a total of 395 included participants. Results: Of the 395 respondents meeting the inclusion criteria (aged 18–50, no cancer or chronic gastrointestinal disorders), 63.5% were females, predominantly urban (90.1%), and highly educated. Mean age was 32.4 years; mean BMI was 25.07 kg/m². The proposed colorectal cancer-preventive diet was rated as “quite attractive” and “very attractive” by 74.9% of participants. All meals received high ratings, with dinner and the first snack being most favored. Most respondents (77.2%) found the diet satisfying and the satiety level and energy adequate, and 90.4% were willing to adopt it at least a few times per week. Financial accessibility was affirmed by 77.2% of the respondents. However, 61.8% reported difficulty eliminating red meat consumption. Female participants rated the diet significantly more attractive than males did (p = 0.041). Willingness to adopt the diet strongly correlated with higher acceptability (p < 0.0001), while BMI and education level showed no significant effect. Conclusions: The proposed colorectal cancer-preventive diet was well accepted by Romanian adults aged 18–50, with higher receptivity among women and those with higher education; willingness to adopt the diet at least a few days per week was high, especially among those psychologically ready for dietary change, while key barriers included red meat reduction and perceived cost, underscoring the need for gender-sensitive, culturally adapted interventions and further research on long-term adherence and clinical impact.

FLOWERING LOCUS T (FT) is a key integrator of flowering pathways. White lupin, a grain legume, encodes four FT homologs: LalbFTa1, LalbFTa2, LalbFTc1, and LalbFTc2. Widespread distribution of white lupin implies diverse phenological adaptations to contrasting ecosystems. Recent studies highlighted associations between FT indels and flowering regulation. Therefore, we surveyed the global white lupin collection for the presence of such indels and potential links to phenology. A panel of 626 white lupin genotypes, representing several European and African agro-climates, was phenotyped under a long-day photoperiod in a two-year study, showing up to 80 days of flowering time difference between early landraces from Eastern Mediterranean and late accessions from France, Madeira, the Canaries, Greece, Italy, and the Azores. As many as seventeen indel variants were identified for LalbFTc1, twelve for LalbFTa2, nine for LalbFTa1, and four for LalbFTc2, yielding roughly three hundred allelic combinations. Significant correlations with phenology were confirmed for one LalbFTa1 indel and twelve LalbFTc1 indels. A large, highly correlated LalbFTc1 indel was revealed to be conserved among all domesticated Old World lupins, carrying all FTc1-promoter candidate binding sites of the same major floral repressor, AGAMOUS-LIKE 15. A small LalbFTa1 indel, providing additional contribution to earliness, showed homology between white and yellow lupins. LalbFTc1 indel-based PCR markers revealed high discriminatory power towards early (PR_42a and PR_71b) or late (PR_58c, PR_36b, PR_80, and PR_60b) flowering. Full article

Bambara groundnut (Vigna subterranean) is an important legume grain in sub-Saharan Africa, including South Africa. Nevertheless, the peculiarity of being hard to cook and mill and the availability of antinutritional factors often limit Bambara groundnut (BGN) use in food applications. This study investigated the impact of dehulling and malting on the nutritional composition, antinutritional factors, and protein digestibility of flours obtained from three BGN varieties (red, cream, and brown). Dehulling and malting significantly enhanced the moisture and protein content of BGN flours (dry basis), with values varying from 6.01% (control brown variety) to 8.71% (malted cream and brown varieties), and from 18.63% (control red variety) to 21.87% (dehulled brown), respectively. Dehulling increased the fat content from 5.82% (control red variety) to 7.84% (dehulled cream), whereas malting decreased the fat content. Nevertheless, malting significantly increased (p < 0.05) the fiber content from 4.78% (control cream) to 8.28% (malted brown variety), while dehulling decreased the fiber content. Both processing methods decreased the ash and carbohydrate contents of the BGN flours. Dehulling and malting significantly enhanced the amino acids of BGN flours, except for tryptophan and asparagine. Dehulling and malting notably increased the phosphorus, magnesium, potassium, and sulfur contents of the BGN flours, while calcium and zinc were reduced. Malting significantly enhanced the iron content of BGN flour, whereas dehulling reduced it. Both processing methods significantly enhanced palmitic, arachidic, and y-Linolenic acids. Nonetheless, processing methods significantly reduced phytic acid and oxalate, and dehulling achieved the most significant reductions. Dehulling and malting significantly enhanced the protein digestibility of the BGN flours from 69.38 (control red variety) to 83.29 g/100 g (dehulled cream variety). Overall, dehulling and malting enhanced the nutritional quality and decreased the antinutritional factors of BGN flours. Full article

Intercropping is an eco-friendly agricultural practice that can lead to increased productivity and improved resource efficiency. This two-year field study (2022–2023 and 2023–2024) aimed to evaluate the yield and quality (protein content) of lentil when intercropping with bread wheat (Yekora) and oat (Kassandra) under two spatial arrangements (1:1 alternate rows and mixed rows at a 50:50 seeding ratio) in northwestern Greece. A completely randomized design was applied with three replications. Differences were found between treatments regarding yield as well as protein content. Results showed that the highest total grain yield (2478.6 kg/ha) and land equivalent ratio (LER = 2.50) were recorded in the Yekora + Thessalia combination (alternate rows). Legume protein content remained consistently high (27–31%), while cereal protein content varied with genotype. Intercropping in alternate rows generally outperformed mixed sowing, indicating the importance of spatial arrangement in optimizing resource use. These findings suggest that properly designed cereal–lentil intercropping systems can enhance yield and quality while supporting sustainable agricultural practices. Intercropping of Yekora with lentil was superior compared to lentil and bread wheat monocultures and can be recommended as an alternative method for the production of human and animal food.

Background: Population aging presents major public health challenges. Nutrition education has emerged as a key intervention to improve diet quality and reduce the risk of chronic diseases among older adults. Methods: This pilot cross-sectional study assessed the effects of a brief nutrition education session on dietary patterns, lifestyle behaviors, and health perceptions among 151 community-dwelling Polish seniors aged 60 and over. Data were collected using the KomPAN® questionnaire, the Pro-Healthy Diet Index (pHDI-10), the Non-Healthy Diet Index (nHDI-14), and self-reported health indicators. Results: The findings revealed suboptimal dietary patterns, including low consumption of whole grains, legumes, and fish. A high prevalence of chronic diseases was observed, particularly hypercholesterolemia (67.7%) and hypertension (53.1%). A weak but significant correlation was found between BMI and the number of diagnosed conditions (r = 0.3, p = 0.003). Despite limited prior nutritional knowledge, participants perceived the educational session as beneficial, and many expressed an intention to share the acquired information with peers, indicating a potential “domino effect”. Conclusions: Although the sample size limits generalizability, the results support the effectiveness of brief, tailored nutrition education as a scalable, cost-effective public health strategy. Such interventions may promote healthy aging, reduce diet-related disease burden, and enhance peer-driven knowledge dissemination among older adults. Full article

Common vetch (Vicia sativa L.) is a legume widely used both as a grain and as forage due to its high protein content, which provides considerable nutritional enrichment for livestock feed. As a cover crop, it has the potential to fix atmospheric nitrogen through symbiosis with rhizobia, contributing to sustainable agricultural systems by enhancing soil fertility and reducing the dependence on chemical fertilizers. Although much research has been focused on optimizing Rhizobium inoculants to enhance biological nitrogen fixation (BNF) in leguminous crops, the role of host plant genetic diversity in BNF has been underexplored. This study analyses a collection of V. sativa genotypes to evaluate their BNF by assaying their nodulation capacity, nodule nitrogenase activity, nitrogen fixation potential, and impact on biomass development. Our results reveal large variability in these parameters among the different genotypes, emphasizing the relevance of host legume diversity in the Rhizobium symbiosis. These findings show a direct relationship between nodule biomass development, nitrogen fixation capacity, shoot biomass production, and nitrogen content. However, no correlation was observed for other parameters such as the number of nodules, nitrogenase activity, and shoot nitrogen content. Taken together, these results suggest that selecting genotypes with high BNF capacity could be a promising strategy to improve nitrogen fixation in legume-based agricultural systems. Full article

Background/Objectives: Recent decades have seen a remarkable westernization of diets and a decline in adherence to the Mediterranean diet (MD). This study examined the eating habits of a representative sample of Italian university students to identify the determinants of adherence to the MD and the most relevant actions to improve their well-being. Methods: The Mediterranean Diet Quality Index for Children and Adolescents (KIDMED) and Sustainable Healthy Diet (SHED) index questionnaires were used to explore MD adherence as the primary outcome, and dietary behavior sustainability, respectively. Sociodemographic, anthropometric, and lifestyle information was also collected. Results: The final sample included 1434 subjects (18–24; 60% female). The median (IQR) KIDMED score was 6.0 (4.0–8.0) and 33% showed a high adherence to the MD. Having breakfast, eating fruit and vegetables at least once a day, consuming pasta or other grains almost daily, and using olive oil at home were among the most common positive aspects of students’ diets. However, regular consumption of fish, nuts, legumes, dairy products, and a second serving of fruit and vegetables was less prevalent. Having an active lifestyle, eating more plant products, and having more sustainable dietary behaviors in terms of the SHED index, were the main determinants of a high KIDMED score. Likewise, graduate students, daily consumers of plant-based meat alternatives, and students attending university canteens daily were more likely to adopt healthier diets. Conclusions: Future actions are crucial to create a food environment that facilitates healthy and sustainable dietary choices among young adults, such as improving the nutritional quality of processed products and regulating their promotion, as well as implementing initiatives to improve university food services and encourage the use of campus dining facilities.

Objectives: This study comparatively evaluated changes in the food habits and dietary patterns of adults aged ≥65 years before and during the coronavirus disease 2019 (COVID-19) pandemic using a retrospective study. Methods: Data covering the 2018–2021 period were derived from the Korea National Health and Nutrition Examination Survey. Results: Comparing the 2943 individuals in the “Before-COVID-19” individuals with the 2916 people in the “During COVID-19” group, the frequency of drinking four or more times a week decreased among the older adults during the pan-demic, as did the frequency of eating three meals a day and eating-out at least once a week. On the other hand, food security improved during the pandemic compared with before the pandemic. During the pandemic, the intake of cereals and grains decreased, while that of potatoes and starches, legumes, vegetables, eggs, milk and dairy products, and oils and fats increased. Although energy and carbohydrate intake decreased, protein, fiber, calcium, phosphorus, magnesium, potassium, zinc, riboflavin, vitamin E, vitamin C, folic acid, and fat intake increased. However, the intake of vitamin A, vitamin C, and calcium remained lower than the estimated adequate requirement of the Dietary Reference Intakes for Koreans. Additionally, the rate of nutritional insufficiency “During COVID-19” (20.76%) was 1.31–1.42 times higher than that “Before COVID-19” (16.45%). Even in models that adjusted for other factors, the rate of nutritional insufficiency was higher during the pandemic than before. Conclusions: Based on these findings, measures such as dietary education programs and guidelines for proper nutrient intake should be formulated to prevent imbalances in nutrient intake among older Koreans.

Chronic kidney disease (CKD) is a widespread condition with significant cardiovascular risks and a progression to end-stage kidney failure. In recent years, increasing attention has been paid to the role of dietary interventions as a factor capable of influencing disease trajectory. This review summarizes the current observational and interventional evidence on various dietary approaches in patients with CKD and kidney transplants (KTs), including Mediterranean, plant-based, and low-protein diets. A balanced Mediterranean diet, rich in fruits, vegetables, whole grains, fish, and unsaturated fats, shows promises in improving the prognosis for CKD patients. Plant-based diets, which emphasize legumes, vegetables, and grains while minimizing animal protein, improve blood pressure and the glycemic and lipid control. Low-protein diets (LPDs), typically providing less than 0.6 g/kg/day of protein, may reduce the CKD progression and nitrogen burden, further delaying the initiation of dialysis. In conclusion, diets represent a valuable and underutilized therapeutic strategy in the management of CKD and KTs, influencing disease progression and patient outcomes. Full article

The EAT-Lancet diet outlines target consumption for specific food components but overlooks accessibility and cost issues, which may hinder adherence among vulnerable populations. This study examines the acquisition profile of EAT-Lancet diet components by food security and poverty status, using data from 57,920 households in the 2017–2018 Brazilian Household Budget Survey. Poverty and food insecurity were defined according to the World Bank per capita income cutoffs and the Brazilian Food Insecurity Scale, respectively. Food acquisition was classified into 15 EAT-Lancet diet components and expressed as per capita daily averages (g, % of total available energy, and % of food expenditure), by food security and poverty strata. Brazilian households were 37.9% food-insecure and 12% poor. Compared to more privileged counterparts, these households prioritized the acquisition of staples like refined cereals and legumes over most EAT-Lancet diet adequacy components, such as fruits, vegetables, whole grains, nuts, and peanuts. While lower energy shares from moderation components were only slightly evident for red meat and dairy among food-insecure households, pronounced reductions in added sugars and vegetable oils were seen among the poor. These findings suggest that public policies should synergically address particularities of different deprivation contexts to promote sustainable diets in Brazil. Full article

After legumes, cereals are the most important source of protein for humans and livestock worldwide. One way to meet growing nutritional demands is to increase the grain protein content (GPC) of cereals. Breeding advances in this regard should be supported by optimized agricultural practices. The GPCs of winter rye, winter triticale, spring barley, and spring oats grown in 2018–2022 in northeast Poland were evaluated to determine the influence of the crop sequence system (continuous monocropping, crop rotation), cultivar (two for each species), plant protection level (control treatment, herbicide, herbicide, and fungicide), and interactions among these factors. The cultivar selection was a significant GPC determinant in all cereals. Growing triticale in crop rotation after a legume increased its GPC compared to continuous monocropping, but decreased the GPC of rye and had no effect on the GPCs of spring cereal that followed non-legume crops. Using herbicides and herbicides combined with fungicides promoted the GPC of rye and oats, but not of triticale and barley. The heterogeneity of the interaction effects of the studied agricultural practices on the GPCs of the individual cereals prevents the identification of a universal combination that would ensure the highest GPC levels. The inter-annual weather variability played a significant role in shaping the GPCs of cereals and in modifying the influence of the controlled factors. Full article

Vegetarianism, as a dietary pattern, is characterized by animal product avoidance and increased consumption of fruits, vegetables, whole grains, and legumes. It has been associated with health benefits, both physical and psychological, and has raised interest as a potential strategy for cancer prevention and treatment, which remains one of the leading causes of morbidity and mortality worldwide, demanding continual exploration of novel approaches. Background/Objectives: This study aims to describe trends in scientific publications about the relationship between vegetarianism and cancer and to highlight research gaps using bibliometric analysis. Methods: The methodology includes comprehensive research of three literature databases. After combining and cleaning these data, a final sample of 3427 studies was obtained that was analyzed using the Bibliometrix-R package. Results: The results indicate a continuously growing production of scientific publications. The most impactful sources, authors and their collaborations were identified. Author keywords, their co-occurrence network, and thematic trends were studied. Conclusions: Through synthesizing and critically evaluating insights from the scientific literature, we aim to contribute to the understanding of the potential benefits of vegetarianism in cancer prevention and management. However, due to the complexity of the topic, the results are often contradictory and could be used as a starting point for further research. Full article
