Urban markets are key nodes for the persistence and adaptation of traditional edible plant knowledge, linking rural production with urban consumption. This study was based on monthly market surveys conducted throughout 2025 in an urban market in Baise City, Guangxi, China. A total of 54 edible plant taxa were recorded, including both native and introduced species, with herbaceous plants predominating alongside climbers, trees, and grasses. Ethnobotanical data were obtained through semi-structured interviews with 40 local informants (20 men and 20 women, aged 25–65 years) selected using purposive sampling, focusing on individuals actively involved in purchasing and preparing edible plants. High Cultural Food Significance Index (CFSI) values highlighted culturally central taxa, including Allium ascalonicum L., × Brassarda juncea (L.) Su Liu & Z.H. Feng, and Houttuynia cordata Thunb., reflecting frequent use and culinary–medicinal integration. Fidelity Level (FL) analyses identified species with strong consensus for specific therapeutic applications, such as × B. juncea, Alpinia galanga (L.) Willd., and Nelumbo nucifera Gaertn., while Informant Consensus Factor (FIC) values indicated moderate to high agreement across gastrointestinal, respiratory, inflammatory, and other health categories. These results underscore the persistence of the “food as medicine” concept, showing that edible plants function simultaneously as nutritional and preventive healthcare resources. The overlap of culinary and medicinal roles demonstrates dynamic food–medicine integration, with urban markets acting as cultural hubs that maintain dietary diversity, household food security, and ethnobotanical knowledge. Future studies should incorporate ethnozoological resources and longitudinal monitoring to capture the full scope of urban food–medicine systems. Full article

Originating in East Asia, the adzuki bean (Vigna angularis) is a diploid crop mainly grown in this region that belongs to the Fabaceae family. As a potential functional food resource with both medicinal and nutritional value, it offers various health benefits. However, research on its chemical constituents, particularly key bioactive components such as triterpenoid saponins and flavonoids, remains relatively limited. In this study, a new triterpenoid saponin, adzukisaponin A (1), along with eleven known compounds (2–12), were isolated from adzuki bean (V. angularis). Among them, compounds 3 (yunganoside B1), 6 (3β-acetyl oleanolic acid), and 7 (β-amyrin) are reported from this source for the first time. Saponins 1–3 and flavonoid 8 exhibited significant dual inhibitory activity. Notably, saponins 1–3 inhibited pancreatic lipase (IC₅₀ = 0.11 ± 0.18 to 0.40 ± 0.21 mM) more strongly than the positive control orlistat, while also acting against α-glucosidase (IC₅₀ = 0.14 ± 0.11 to 0.23 ± 0.17 mM). Molecular docking supported their binding to the enzymes’ active sites. This study identifies 1–3 and 8 as dual α-glucosidase/pancreatic lipase inhibitors, underscoring the potential of adzuki bean as a source of bioactive functional food ingredients. Full article

Background/Objectives: Whole food, plant-based (WFPB) diets have been associated with reduced cardiovascular risk and enhanced overall health. However, nutrition education in medical training remains limited. This study evaluated an experiential WFPB intervention known as the “Plant Plunge.” Methods: A total of 64 medical student participants attended weekly one-hour nutrition seminars on campus led by a local nonprofit, received complimentary WFPB lunches, and were encouraged to eat a WFPB diet for four weeks. Semi-structured interviews explored program perceptions. Pre- and post-intervention assessments measured nutrition knowledge, and a post-program survey assessed attitudes toward the intervention. Results: We analyzed a total of 14 interviews, 25 pre- and post-intervention knowledge assessments, and 49 post-intervention surveys. Qualitative analysis identified seven major themes: (1) improved physical health outcomes; (2) increased awareness of nutrition’s role in medicine; (3) concerns about feasibility and accessibility of WFPB diets; (4) personal empowerment and behavioral change; (5) educational value of seminars; (6) social engagement and peer support; and (7) relevance to future clinical practice. Mean scores on the knowledge assessment significantly improved from 73.3% to 87.0% (p = 0.045) following the Plant Plunge. Survey responses revealed that 65% of participants agreed that they increased knowledge of food ingredients, 54% indicated increased likelihood of selecting plant-based options, and 43% agreed that finding WFPB foods was easy, with 16% disagreeing. Conclusions: The Plant Plunge improved medical students’ nutrition knowledge, dietary attitudes, and perceived readiness for lifestyle counseling while offering an experiential model of nutrition education. Short, experiential nutrition programs may serve as scalable approaches to strengthen nutrition training and support chronic disease prevention. Full article

Background/Objectives: Sodium-glucose co-transporter 2 (SGLT2) inhibitors are essential antidiabetic medications. However, their side effects warrant careful consideration. The search for novel SGLT2 inhibitors with high affinity remains an ongoing endeavor. Medicine food homology (MFH) herbs show promise for drug development due to their nutritional and medicinal value. Methods: This study aims to address the shortcomings of existing virtual screening models for SGLT2 inhibitors by optimizing feature selection and integrating multidimensional molecular fingerprints. Subsequently, an integrated virtual screening pipeline is constructed to identify potential SGLT2 inhibitors from eight selected MFH herbs. Results: The results indicate that the optimal model (LightGBM and RF) achieved an accuracy of 0.97 and an AUC of 0.98. Following rigorous filtering, a total of 44 potential SGLT2 inhibitors were identified, among which, Isoononin (from Gancao) and Ononin (from Huangqi, Gegen, and Gancao) exhibit favorable drug likeness and safety. Molecular docking demonstrate that both compounds can effectively bind to the SGLT2 active site, establishing stable hydrophobic interactions with critical residues such as Phe98 and Phe453. Furthermore, molecular dynamics simulations confirm the stability of the interactions between the two compounds and SGLT2. Conclusions: This study significantly enhances the accuracy and stability of SGLT2 inhibitor virtual screening models by addressing deficiencies in structural characterization and feature selection. It provides candidate molecules for the development of novel SGLT2 inhibitors and offers new scientific evidence for the application of MFH herbs in the prevention and treatment of chronic metabolic diseases.

Background: Vancomycin is a critically important antimicrobial in human medicine, and vancomycin-non-susceptible enterococci represent a One Health concern when animal reservoirs contribute to the wider resistance ecology. We aimed to characterize vancomycin non-susceptibility among poultry-derived Enterococcus spp. from Hungary, using a combined phenotypic–genomic approach. Methods: Following a phenotypic pre-screen with antimicrobials authorized for poultry, 218 isolates with elevated minimum inhibitory concentrations (MICs) were selected for extended broth microdilution testing including vancomycin. Vancomycin susceptibility was interpreted using Clinical and Laboratory Standards Institute (CLSI) clinical breakpoints and European Committee on Antimicrobial Susceptibility Testing (EUCAST) epidemiological cut-off values (ECOFFs). Whole-genome sequencing was performed on a targeted multidrug resistant (MDR) subset (n = 42), enriched for elevated or borderline vancomycin MICs and stratified by region and host species (chicken, turkey), and resistance determinants were annotated against the Comprehensive Antibiotic Resistance Database (CARD) using stringent similarity/coverage thresholds. Results: Among the 218 pre-screened isolates (126 from chickens; 92 from turkeys), 196 (89.9%) met MDR criteria. For vancomycin, 15.6% of isolates were resistant and 9.2% intermediate by CLSI, while EUCAST ECOFF classification placed 34.9% in the non-wild-type group. The vancomycin MIC distribution was right shifted, with high-end MICs observed. In the sequenced subset, vancomycin-associated determinants consistent with the vanC pathway (including regulatory and auxiliary components) were detected in five isolates. Beyond vancomycin-related determinants, the WGS subset harbored common resistance genes consistent with the observed multidrug-resistant phenotypes. Conclusions: Vancomycin non-susceptibility was detected among pre-screened poultry-derived Enterococcus isolates in Hungary, and genomic analysis revealed vanC-associated and other peptide antibiotic resistance signatures. These findings support targeted One Health surveillance integrating MIC distributions with genomic resistance determinants in food animal reservoirs. Full article

Background/Objectives: The rhizome of Gastrodia elata Blume (Tianma) is a functional food with medicinal value in China, used to improve the health of the central nervous system and reported to exhibit anti-cellular senescent activity. P-hydroxybenzaldehyde (P-HBA) is a key aromatic compound isolated from Tianma; however, its potential to mitigate cellular senescence remains unclear. Methods: We employed ultra-performance liquid chromatography-mass spectrometry to identify the chemical characterization of Tianma extract. Cell viability assay, senescence-associated-β-galactosidase (SA-β-Gal) assay, and immunofluorescence staining and autophagy analysis were used to evaluate the anti-senescent activity of P-HBA and other Tianma components. Results: Our findings demonstrate that Tianma methanol extract (TME) and P-HBA significantly reduce cellular senescent inducer hydroxyurea (HU)-induced DNA damage, SA-β-Gal activity increase, and autophagic dysfunction in human SH-SY5Y cells. Notably, an autophagy inhibitor, chloroquine, can reduce anti-cellular senescent activity of P-HBA. Conclusions: These results suggest that P-HBA exhibits the effect of reducing cellular senescent phenotypes, and its effect is achieved by enhancing autophagy. Full article

Anise (Pimpinella anisum L.) is one of the most important annual herbs of the Apiaceae family, widely cultivated in southern Spain. Their seeds are highly valued for culinary uses and for producing quality essential oils widely used in food and beverage products, as well as for industry, medicinal, and cosmetics applications. This study investigates the seed yield and essential oil content within a set of 50 anise accessions from worldwide origin, as well as their composition by GC–MS and GC–FID analysis. Accessions showed significant differences in the agronomic parameters measured, including plant height (cm), seed yield (kg ha⁻¹), and the Harvest Index (%), with accessions PA_87 (Spain), PA_47 (Greece), and PA_21 (unknown origin) being the most performant. Essential oil (EO) content varied between 0.8% and 5.7% across different genotypes, resulting in EO production values ranging from 0.1 to 300 kg ha⁻¹. Trans-anethole was identified as the dominant terpene, comprising 84.4% to 94.4% of the content, followed by eugenol (1.4% to 5.5%) and α-muurolene (1.4% to 7.2%). PCA analysis identified five distinct groups and one outlier, influenced by minor terpenes. Indeed, there was a strong negative correlation between estragole and pseudoisoeugenyl 2-methylbutyrate. This study underscores the significance of minor terpenes, which play crucial roles in defining unique aniseed chemotypes, allowing for the selection of cultivars optimized for specific uses in food, cosmetics, and pharmaceuticals. Additionally, these findings emphasize the impact of cultivar genetics on agronomic traits and EO profiles, suggesting the need for further research to optimize plant growth and yield and EO quality.

Tylorrhynchus heterochaetus is an aquatic food with both edible and medicinal value in China. With a protein-rich body wall, it has strong potential for producing bioactive peptides. To explore its potential as a source of immunomodulatory peptides, in this study, flavor enzymes were selected as the optimal hydrolases, and the hydrolyzed products were subjected to ultrafiltration fractionation. The <3000 Da portion exhibited the most effective immune-stimulating activity in RAW 264.7 macrophages, enhancing phagocytosis and promoting the secretion of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and nitric oxide (NO) in a concentration dependent manner. Peptide omics analysis, combined with the activity and safety screened by bioinformatics, identified 43 candidate peptides. Molecular docking predicts that three novel peptides, LPWDPL, DDFVFLR and LPVGPLFN, exhibit strong binding affinity with toll-like receptor 4/myeloid differentiation factor-2 (TLR4/MD-2) receptors through hydrogen bonding and hydrophobic/π stacking interactions. Synthetic verification confirmed that these peptides were not only non-toxic to cells at concentrations ranging from 62.5 to 1000 µg/mL, but also effective in activating macrophages and stimulating the release of immune mediators. This study successfully identified the specific immunomodulatory peptides of the Tylorrhynchus heterochaetus, supporting its high-value utilization as a natural source of raw materials for immunomodulatory functional foods.

Background: The Chinese dwarf cherry (CDC) has been valued for over 2000 years for its medicinal and nutritional properties, particularly its kernels. Despite its recognition as a rich source of oil, the potential health benefits of CDC kernel oil remain unclear. Method: Initially, we evaluated the preventive effectiveness of CDC in a mouse model of constipation induced by loperamide. Results: The findings indicated that CDC kernel oil alleviated constipation by reducing the first black fecal defecation time and increasing the fecal number, wet weight, water content and gastrointestinal transit rate in model mice. Additionally, CDC kernel oil reduced inhibitory neurotransmitters and increased excitability neurotransmitters, two anti-oxidases’ activity and fecal short-chain fatty acid (SCFA) content. Histological analysis revealed an improved mucus cell morphology in the intestinal tract. Furthermore, CDC kernel oil increased the abundance of some beneficial bacteria. It was identified that the gut microbiota was associated with neurotransmitters, mediators of inflammation and SCFAs. Conclusion: The findings offer a scientific foundation for considering CDC kernel oil as a potential functional food for the alleviation of constipation. Full article

Local vegetables and spices are essential components of traditional food and health systems in northeastern Thailand, yet quantitative ethnobotanical evidence remains limited. This study documents the diversity, utilization, and cultural significance of vegetables and spices used in Sang Kho Sub-district, Phu Phan District, Sakon Nakhon Province. Ethnobotanical data were collected in 2025 through field surveys, voucher-based plant identification, semi-structured interviews, and participant observation involving 92 informants across 23 villages. Cultural significance and medicinal knowledge were evaluated using the Cultural Importance Index (CI), Informant Consensus Factor (FIC), and Fidelity Level (FL). A total of 113 taxa belonging to 94 genera and 49 plant families were recorded. Poaceae and Zingiberaceae were the most species-rich families. Native species slightly predominated (51.33%), and herbaceous taxa were most common. Leaves were the most frequently used plant part. Most taxa were used as vegetables (92 species), followed by traditional medicines (20 species), spices or seasonings (18 species), and food ingredients or culinary additives (18 species). The highest CI values were recorded for Allium ascalonicum L. (1.152), Capsicum annuum L. (1.098), and Coriandrum sativum L. (1.043). FIC values ranged from 0.60 to 1.00, with complete consensus for circulatory and neurological disorders. Cymbopogon citratus showed the highest FL (75%) for gastrointestinal uses. These findings demonstrate the close integration of food and medicine in local plant-use systems and provide baseline data for food system resilience and cultural knowledge conservation.

A huge amount of waste is produced annually by the food processing industry which must be valorized into high-value products. Therefore, the aim of this work involves the use of such wastes for production of β-glucans from medicinal basidiomycete strains which are powerful biological response modifiers in several clinical disorders. The production of β-glucans from basidiomycete strains in submerged fermentation was monitored by using monoclonal antibodies of the IgG and IgM classes as well as by Congo red assay in the presence of several agro-industrial waste products such as milk permeate, waste coffee grounds, orange peels and rice husks. Subsequently, these β-glucans were purified by using gel filtration and ion-exchange chromatography. FTIR analysis of several β-glucans was carried out to investigate their structural properties. The adsorption of β-glucans on microtiter plates was dependent on the temperature as well as on the time period of immobilization for ELISA. These mAbs can be used in a competitive ELISA for detection and quantification of β-glucans from basidiomycete mushrooms. Full article

Background: Ultra-processed foods (UPFs) have emerged as a critical component of diet quality, yet data on the associations between UPF and nutrient intakes remain limited. This study aimed to evaluate nutrient consumption in relation to UPF intake and adherence to international dietary guidelines for non-communicable disease (NCD) prevention. Methods: Data from 469 individuals aged 2–18 years enrolled in the Hellenic National Nutrition and Health Survey (HNNHS) were analyzed. Intakes were assessed using two 24 h recalls, and foods were classified according to the NOVA system. Participants were categorized by UPF energy intake tertiles. Nutrient adequacy was assessed using Nordic Nutrition Recommendations, European Society of Cardiology guidelines for macronutrients, and the Institute of Medicine’s Estimated Average Requirements and Adequate Intake values for micronutrients. Results: Children in the highest UPF tertile had significantly higher intakes of energy, carbohydrates, added sugars, saturated fats, polyunsaturated fats, and cholesterol, but lower intakes of protein compared to those in the lowest tertile. Fiber intake remained inadequate across all tertiles, with no significant differences. Regarding adherence to NCD prevention guidelines, children in the 3rd UPF tertile had a 2.3 times higher prevalence ratio for exceeding added sugar recommendations, while their protein intake prevalence ratio was 0.8 times lower. For micronutrients, the highest UPF tertile showed significantly elevated intakes of vitamins E, B₁, folate, calcium, iron, copper, and sodium, but lower potassium intake compared to the lowest tertile. Conclusions: Our results underscore the need for effective public health strategies to improve diet quality in children and adolescents and prevent diet-related NCDs. Full article

In today’s world, unhealthy living habits have contributed to the rise in metabolic disorders like hyperlipidemia. Recognized as a popular edible and medicinal mushroom in China and various eastern nations, Ganoderma lucidum is a promising high-value functional and medicinal food with multiple biological activities. Our earlier research has demonstrated that G. lucidum polysaccharides (GLP) showed distinct lipid-lowering abilities by enhancing the response to oxidative stress and inflammation, adjusting bile acid production and lipid regulation factors, and facilitating reverse cholesterol transport through Nrf2-Keap1, NF-κB, LXRα-ABCA1/ABCG1, CYP7A1-CYP27A1, and FXR-FGF15 pathways, hence we delved deeper into the effects of GLP on hyperlipidemia, focusing on its structural characterization, gut microbiota, and fecal metabolites. Our findings showed that GLP changed the composition and structure of gut microbiota, and 10 key biomarker strains screened by LEfSe analysis markedly increased the abundance of energy metabolism, and cell growth and death pathways which were found by PICRUSt2. In addition, GLP intervention significantly altered the fecal metabolites, which enriched in amino acid metabolism and lipid metabolism pathways. The results of structural characterization showed that GLP, with the molecular weight of 12.53 kDa, consisted of pyranose rings and was linked by α-type and β-type glycosidic bonds, and its overall morphology appeared as an irregular flaky structure with some flecks and holes in the surface. Collectively, our study highlighted that the protective effects of GLP were closely associated with the modification of gut microbiota and the regulation of metabolites profiles, thus ameliorating dyslipidemia.

Amaryllidaceae alkaloids are of notable pharmacological relevance. For instance, galanthamine is used in the treatment of Alzheimer’s disease, while other alkaloids (lycorine, crinine, etc.) derived from Amaryllidaceae plants are also of great interest because they exhibit antitumour, antiviral, antibacterial, antifungal, antimalarial, analgesic and cytotoxic properties. Phenolic acids comprise a group of natural bioactive substances that have commercial value in the cosmetic, food and medicinal industries due to their antioxidant, anticancer, anti-inflammatory and cardioprotective potential. In the present study, the effect of temperature (15, 20, 25 and 30 °C) on Amaryllidaceae alkaloid and phenolic acid biosynthesis in Leucojum aestivum in vitro plant cultures was investigated. The highest diversity of alkaloids (i.e., galanthamine, crinan-3-ol, demethylmaritidine, crinine, 11-hydroxyvitattine, lycorine, epiisohaemanthamine, chlidanthine) was noted in plants cultured at 30 °C. By contrast, ismine and tazettine were only present in plants cultured at 15 °C. Temperatures of 20 °C and 30 °C were found to stimulate galanthamine accumulation. The highest lycorine content was noted in plants grown at temperatures of 15 and 30 °C, and it was negatively correlated with the expression of the gene that encodes the cytochrome P450 96T (CYP96T) enzyme which catalyses a key step in the biosynthesis of different types of Amaryllidaceae alkaloids. This observation may reflect temperature-induced shifts in metabolic flux among different branches of Amaryllidaceae alkaloid biosynthesis. The observed stimulating effect of a 15 °C temperature on the chlorogenic, caffeic, p-coumaric, sinapic, ferulic and isoferulic acid content was in line with the highest expression of a gene that encodes the tyrosine decarboxylase (TYDC) enzyme, which is involved in plant stress response mechanisms. At 30 °C, however, the highest content of the caffeic, vanillic, p-coumaric and isoferulic acids was noted. Full article
