Pediatric disorders of gut–brain interaction (DGBIs) comprise chronic or recurrent symptom-based gastrointestinal conditions that cannot be fully explained by identifiable structural, biochemical, or organic abnormalities after appropriate clinical evaluation. The term DGBI is used throughout this review in accordance with current terminology, whereas the historical term “functional gastrointestinal disorders” (FGIDs) is retained only when referring to studies that used earlier Rome classifications. This review examines the impact of four modifiable factors—sleep, psychological stress, circadian rhythm, and diet—on their development and severity in children and adolescents. Relevant literature was identified through PubMed, with emphasis on recent pediatric studies, systematic reviews, and meta-analyses. Sleep disturbances are associated with greater abdominal pain, functional disability, and impaired daytime functioning. Stress may exacerbate symptoms through hypothalamic–pituitary–adrenal axis activation, autonomic imbalance, altered motility, and visceral hypersensitivity. Circadian disruption may affect gastrointestinal motility, barrier function, enteroendocrine signaling, and microbial rhythmicity, although pediatric evidence remains limited. Diet influences fermentation, microbiota, intestinal permeability, and symptom expression, with regular meals, adequate hydration, and appropriate fiber intake representing important initial measures. These factors interact bidirectionally through shared neuroendocrine, autonomic, immune, and microbial pathways. Clinical management should therefore adopt a biopsychosocial, multidisciplinary approach combining symptom management with modification of sleep, stress, circadian habits, and dietary patterns. Further prospective pediatric studies are needed to clarify causality and support personalized interventions. Full article

Intensive yak fattening in cold alpine regions requires essential long-term high-concentration feeding, which disrupts rumen microbial homeostasis and causes inefficient digestion of nutrients. Lactobacillus may have probiotic potential for ruminants, yet its regulation of rumen function is poorly understood under high-energy diets. During a 120-day feeding experiment, 120 male Pamir yaks were allocated to four dietary treatments, with LEG and LLG serving as the primary comparison for evaluating 0.02% Lactobacillus supplementation to explore the regulatory effects of Lactobacillus supplementation on the rumen microbiota and host metabolism of yaks during a fattening process based on a concentrate feed diet via phenotypic data (body wight and nutrient digestibility) and multi-omics analyses (rumen microbial sequencing and rumen epithelial transcriptome) in a concentrate-based rearing yak model. The results showed that Lactobacillus intervention reduced OTU (Operational Taxonomic Unit) richness during the early fattening period and subsequently promoted microbial recovery through colonization resistance, which significantly enhanced microbial diversity (p < 0.05), and restructured the microbial community structure toward efficient energy utilization under high-concentrate feeding by reducing Prevotellaceae and Ruminococcaceae abundance, increasing the Bacillota/Bacteroidota ratio (p < 0.05). Concurrently, Lactobacillus enhanced the apparent digestibility of dry matter, crude protein, and fibrous components (p < 0.05). According to the transcriptomic analysis, there was an activation of signaling pathways related to IL-18 and TNF, and up-regulation of immune-and metabolism-related genes, in addition to strengthening the rumen mucosal barrier function. Multi-omics integration supported that dietary supplementation of Lactobacillus can optimize rumen fermentation, enhance nutrient digestion, and strengthen immune defense in Pamir yaks fed high-concentrate in cold seasons. These modifications demonstrate the positive effects of the Lactobacillus supplementation strategy on yak rumen health without interfering with the high-energy intensive rearing pattern. The present research presents a scientific basis for the use of targeted probiotic strategies to improve the rumen health and efficiency of alpine yak production systems. Full article

Background: Given the rising global prevalence of dementia and its complex etiology, involving genetic and environmental risk factors, the aim of the present exploratory study was to investigate how offspring of individuals with dementia perceive genetic risk and the role of diet in dementia prevention. Methods: A mixed-methods study was conducted in Greece. Overall, 118 offspring completed an online questionnaire assessing demographics, risk perceptions, and dietary beliefs and practices in dementia risk reduction. Additionally, 22 semi-structured interviews explored dietary beliefs, practices, and influencing factors using framework analysis. Results: Most participants (76.3%) recognized diet’s role in dementia prevention, while 52.5% perceived offspring as having increased genetic risk; 40.7% reported making dietary changes to reduce disease risk. Healthcare professional consultation was the factor most strongly associated with dietary modification (OR = 26.61, 95% CI 7.47–94.76, p < 0.001). Qualitative findings showed that, while dementia was viewed as severe, personal susceptibility was often perceived as uncertain or distant. Key barriers, facilitators, and the role of self-efficacy in adopting healthier dietary practices were also explored. Conclusions: Our findings identify personalized dietary counselling and risk communication as priorities for evaluation in future intervention studies, aimed at supporting the implementation of dietary modifications and reducing the gap between knowledge and behavior in dementia risk reduction.

The use of non-traditional oilseeds for food purposes has increased significantly in recent years. Due to the high content of unsaturated fatty acids, the production of cold-pressed oils from pumpkin and hemp seeds is growing at a steady pace. This results in the accumulation of a by-product (oilseed press cake), from which high-quality proteins can be derived. Protein hydrolysates based on these raw materials offer further potential for valorization. This review summarizes classical and modern methods for obtaining protein isolates from pumpkin and industrial hemp oilseed cakes, as well as possible approaches for their modification to enhance their nutritional and functional properties. Furthermore, it provides an overview of the methods for producing protein hydrolysates rich in bioactive peptides. The presence of peptides with antioxidant, antihypertensive, or hypoglycemic properties makes hydrolysates a valuable source of nutraceutical components with potential applications in the development of functional foods or dietary supplements. However, most studies to date have been conducted using in vitro systems. Further research involving animal models or clinical observations is required to determine dosage regimens and applications of these hydrolysates. Regarding protein isolates, the challenges for their broader use in the food industry are related to increasing solubility, removing anti-nutritional factors, and improving techno-functional properties.

Obesity is a complex, multifactorial chronic disease characterized by excessive and/or aberrant adiposity that requires interventions beyond conventional calorie-restriction models. Current clinical guidelines converge on behavioral modification, encompassing nutritional therapy, physical activity, stress reduction, and sleep improvement, as the cornerstone of obesity management, with psychological therapy, pharmacotherapy, and bariatric procedures as adjunctive or escalating options. While traditional “one-size-fits-all” dietary approaches frequently yield suboptimal long-term outcomes, precision nutrition has emerged as a promising strategy for individualized obesity care. This review critically appraises the evidence underlying each pillar of precision nutrition: genetic profiling shows clear utility in monogenic obesity but variable benefit when diet is matched to common polygenic variants; microbiome-targeted studies reveal that the Bacillota to Bacteroidota ratio shows inconsistent associations with obesity across studies, with genus-level and functional alterations offering more reproducible targets; and metabolomic profiling of postprandial glycemic responses has progressed from foundational predictive algorithms to large-scale clinical validation. It also highlights chrono-nutrition, the alignment of food timing with individual chronotype, as an emerging pillar of personalization. Beyond dietary composition, the review addresses how personalized nutrition can mitigate the adverse effects of incretin-based pharmacotherapy and discusses how artificial intelligence can integrate multi-omics and behavioral data into real-time dietary guidance. Future clinical implementation will require overcoming challenges related to data integration, predictive accuracy, and accessibility, paving the way for more effective, evidence-based obesity management.

Prostate cancer is among the most frequently diagnosed cancers in men globally, with metastatic disease contributing substantially to morbidity and mortality. While conventional therapies remain the standard of care, dietary and lifestyle behaviors are increasingly explored as potentially modifiable factors influencing clinical outcomes, although their role in advanced disease is not well established. We report a 60-year-old, physically active male, lifelong non-smoker without significant comorbidities, diagnosed with de novo metastatic prostate adenocarcinoma (Gleason score 9) and an initial prostate-specific antigen (PSA) of 808.3 µg/L. The patient received standard androgen deprivation therapy. By personal choice, he adopted a whole-food, low-fat (WFLF) vegan diet, structured physical activity, and periodic fasting-mimicking diet cycles. These interventions complemented, but did not replace or delay, conventional treatment. During the 14-month follow-up period, serial PSA measurements, laboratory tests, blood pressure monitoring, dietary assessment, body composition analysis, imaging, and germline genetic testing were performed. PSA declined from 808.3 µg/L to 1.7 µg/L (>99.8%), and remained suppressed throughout follow-up. Concurrent improvements were observed in body composition and metabolic biomarkers. The WFLF vegan diet increased fiber and micronutrient intake while reducing saturated fat and cholesterol. This case demonstrates the successful application and execution of an integrative oncology approach and highlights metastatic prostate cancer managed with standard therapy alongside patient-initiated lifestyle modifications. The findings should be interpreted as descriptive, exploratory, and hypothesis-generating. Given the single-patient design, the independent impact of lifestyle interventions cannot be determined. Controlled studies are warranted to clarify their potential role in advanced prostate cancer management. Full article

Background: Gut microbiota plays a key role in the aging process, with age-related microbial shifts contributing to chronic inflammation, metabolic dysfunction, frailty, and cognitive decline. Despite growing interest, an integrated synthesis of how diet and lifestyle modifications influence gut microbiota remains limited. This overview of reviews summarizes the current evidence on how dietary and lifestyle interventions shape microbial composition and affect aging outcomes. Methods: Following the PRISMA guidelines, we searched PubMed and Scopus for English-language reviews (January 2023–October 2025) including human adults aged ≥ 18 years, evaluating dietary or lifestyle interventions, and reporting gut microbiota with healthy-aging outcomes. Quality of the reviews was appraised using the SANRA tool. Results: Mediterranean and plant-based diets, calorie restriction, and microbiota-targeted approaches such as probiotics, prebiotics, symbiotics, and fecal microbiota transplantation were associated with increases in short-chain fatty acid-producing bacteria, including Faecalibacterium, Bifidobacterium, Lactobacillus, and Akkermansia muciniphila, while reducing pro-inflammatory taxa. These changes were linked to improved metabolic and immune function, reduced inflammaging, lower frailty, and greater physical resilience. Cognitive benefits included decreased neuroinflammation and a lower risk of Alzheimer’s and Parkinson’s diseases. Conclusions: Maintaining microbial balance through targeted dietary strategies may support healthier, more resilient aging, offering practical insights for public health and clinical nutrition planning.

Background: To evaluate the effects of three lifestyle modification strategies—dietary supplementation with phenolic acid-rich Brussels chicory (Cho), Brussels chicory supplementation combined with supervised concurrent resistance exercise and high-intensity interval training (Cho-CT) or mindfulness-enhanced concurrent resistance exercise and high-intensity interval training (Cho-MeCT)—on high-density lipoprotein cholesterol efflux capacity (HDL-CEC) from macrophages and HDL subclass profiles (pre-β-HDL, HDL₃, HDL₂) in overweight adults. Methods: This study is an 8-week randomized controlled trial in which 97 overweight college students were randomized to Cho, Cho-CT, Cho-MeCT or control group. HDL-CEC from macrophages, the primary outcome, HDL subclass profiles, plasma activities of lecithin, such as cholesterol acyltransferase (LCAT) and cholesteryl ester transfer protein (CETP) involved in remodeling HDL subclass profiles and plasma lipid profiles, and apolipoprotein AI were assessed at baseline and post-intervention. Results: Compared with the control treatment, all three lifestyle interventions comparably elicited a 1.18% to 1.78% elevations in HDL-CEC from macrophages (p < 0.001). Their improvements were accompanied by reductions in pre-β-HDL and HDL₃ concentrations and increased HDL₂ concentrations. However, there were no significant differences in plasma lipid profiles, apolipoprotein A-I, and plasma LCAT and CETP activities among the tested groups. Within the Cho, Cho-CT, and Cho-MeCT groups, changes in HDL-CEC from macrophages were positively correlated with changes in HDL₂ levels, whereas weak negative correlations were observed for pre-β-HDL and HDL₃, though these associations did not reach statistical significance. No comparable significant correlations were found in the control group. Conclusions: In overweight adults, sustained Brussels chicory supplementation, either alone or combined with concurrent exercise training, may yield comparable favorable changes in HDL-CEC from macrophages and HDL subclass profiles, though effect magnitudes appear modest in this pilot trial.

Background: Type 2 diabetes mellitus (T2D) is one of the fastest-growing chronic diseases worldwide, affecting an estimated 589 million adults in 2024, with projections rising to 853 million by 2050. Dietary modification is a cornerstone of both T2D prevention and management. Among the various dietary approaches, plant-based dietary patterns have gained increasing attention; however, uncertainty remains regarding the optimal dietary composition and the contribution of specific food groups. Methods: This narrative review summarizes the current evidence on plant-based dietary patterns and their association with T2D prevention and metabolic control, with a particular focus on legumes, dietary fiber, and red and processed meat. Evidence from prospective cohort studies, randomized controlled trials, and meta-analyses was evaluated. Results: Higher adherence to healthy plant-based dietary patterns was consistently associated with up to a 30% lower risk of developing T2D, improved insulin sensitivity, and approximately a 0.30–0.47 percentage-point reduction in glycated hemoglobin (HbA_1c). Greater consumption of legumes and dietary fiber was linked to improved glycemic control, enhanced but heterogeneous modulation of gut microbiota composition, reduced low-grade inflammation, and beneficial effects on body weight and lipid metabolism. In contrast, higher intake of processed meat and unprocessed red meat was consistently associated with an increased risk of T2D. Importantly, unhealthy plant-based diets characterized by refined grains, sugar-sweetened beverages, and highly processed foods provided little metabolic benefit and may even increase diabetes risk by up to 13%. The interpretation of the available evidence is limited by the predominance of observational studies, heterogeneous definitions of plant-based dietary patterns, self-reported dietary assessments, and the limited availability of long-term randomized controlled trials. Conclusions: Current evidence supports healthy plant-based dietary patterns as an effective strategy for the prevention and management of T2D. Dietary patterns emphasizing whole plant foods, including legumes, whole grains, fruits, vegetables, nuts, and seeds, while limiting processed and excessive red meat intake, are associated with improved metabolic health. Future high-quality randomized controlled trials with standardized dietary definitions are needed to further define the optimal composition of plant-based diets for diabetes prevention and treatment.

The intrauterine environment plays a critical role in shaping lifelong health, forming the foundation of the Developmental Origins of Health and Disease (DOHaD) paradigm. Increasing evidence suggests that maternal lifestyle factors, particularly physical activity and nutrition, can actively influence embryonic development; however, how exercise and dietary signals interact to regulate developmental programming remains insufficiently understood. In this review, we summarize emerging evidence that maternal exercise and nutrition function as interconnected regulators of embryonic organogenesis through coordinated maternal–placental–fetal communication. Exercise-induced metabolic, endocrine, and immunological adaptations are highly dependent on maternal nutritional status, while dietary composition provides essential substrates and signaling molecules that modulate exercise-mediated benefits. Through regulation of placental function, exerkines, microbiota-derived metabolites, epigenetic modifications, and nutrient-sensing pathways, the integrated exercise–nutrition axis shapes the development of multiple embryonic organ systems and influences offspring health trajectories. We further discuss current challenges in defining optimal combinations of maternal exercise patterns and nutritional strategies, highlighting the need to move beyond isolated interventions toward precision lifestyle approaches during pregnancy. This perspective establishes maternal exercise and nutrition as synergistic modulators of developmental programming and provides a conceptual framework for understanding how combined lifestyle interventions may enhance offspring developmental resilience and reduce the risk of chronic disease across generations.

In modern societies, the renewed concept of food as medicine coexists with unprecedented consumption of highly processed foods, food additives, environmental xenobiotics, and pharmacological agents, contributing to the increasing prevalence of metabolic and degenerative diseases and accelerated aging. Although modern pharmacotherapies have transformed disease management, long-term drug exposure introduces additional metabolic burdens, off-target effects, and cumulative toxicities that are profoundly influenced by nutritional status. Collectively, dietary constituents, environmental chemicals, endogenous metabolic by-products, and therapeutic agents constitute a complex exposome that requires continuous recognition, utilization, detoxification, and clearance. Within this context, the liver sinusoidal clearance system (LSCS) emerges as a central regulator of systemic homeostasis. We propose a conceptual framework in which circulating molecules are classified as self (S), modified self (M), and foreign (F) molecules according to their physiological handling by the LSCS. Through coordinated hepatic utilization of S molecules and selective clearance of M and F molecules, fenestrated liver sinusoidal endothelial cells (LSECs) maintain metabolic homeostasis, immune tolerance, and physiological pharmacokinetics. Conversely, chronic dietary overload, poor dietary quality, food processing, and sustained exposure to pro-inflammatory and oxidative dietary and environmental molecules initiate chronic low-grade inflammation, which promotes LSEC capillarization, impairs hepatic clearance, increases the modification of S molecules into M molecules and establishes a feed-forward cycle that further amplifies chronic inflammation and metabolic dysfunction. Finally, we discuss recent advances in the programmable modulation of the LSCS, including its transient suppression to prolong therapeutic exposure and its activation to enhance the clearance of metabolically harmful M and F molecules through coordinated upregulation of the endoglin–stabilin-2–FcγRIIb axis and the LSEC markers Oit3 and Dnase1L3. We highlight dual-function supramolecular nanofiber platforms that enable bidirectional regulation of the LSCS through nanofiber complexes with therapeutic proteins, thereby expanding their therapeutic potential and enhancing efficacy in the treatment of metabolic, inflammatory, and age-related diseases.

Color instability in anterior composite restorations remains a primary cause for clinical replacement. While pre-polymerization thermal modification is increasingly utilized in daily practice, its precise impact on phase-specific and long-term optical resistance against continuous thermal aging and aggressive dietary staining remains unclarified. This in vitro study evaluated the impact of pre-polymerization thermal modification (4 °C, 23 °C, and 55 °C) on the phase-specific and cumulative color stability (ΔE₀₀) of four anterior composite resins subjected to sequential thermal aging and prolonged coffee immersion. One hundred twenty specimens (n = 10) were prepared, and ΔE₀₀ was assessed using the CIEDE2000 formula at baseline (T0), post-thermal cycling (T1), and post-coffee immersion (T2). Mixed repeated-measures ANOVA revealed a significant three-way interaction (phase × material × temperature, p < 0.001), demonstrating that thermal conditioning effects vary by material formulation and aging dynamics. During thermal aging (ΔE₀₀ T0–T1), pre-polymerization cooling (4 °C) induced significantly higher discoloration in Estelite Sigma Quick compared to preheated conditions (p < 0.001). Following coffee immersion (ΔE₀₀ T1–T2), refrigeration at 4 °C significantly increased staining in Enamel Plus HRI (p = 0.026) and Estelite Sigma Quick (p = 0.007) compared to room temperature and preheated groups. For cumulative color change (ΔE₀₀ T0–T2), the material type was the primary determinant (p < 0.001), while the independent effect of temperature was not statistically significant (p = 0.395). In conclusion, preheating (55 °C) provides no significant cumulative advantage against staining, whereas refrigeration (4 °C) increases susceptibility to physical and chemical discoloration. The intrinsic chemical composition remains the critical factor driving long-term color stability. Full article

Pediatric obesity is a complex, multifactorial pandemic with serious early-onset comorbidities, including prediabetes, type 2 diabetes, metabolic dysfunction-associated steatotic liver disease (MASLD), and cardiovascular disorders. While lifestyle modifications and the Mediterranean diet remain primary interventions, artificial intelligence (AI) is emerging as a critical tool for early diagnosis and personalized management. This review evaluates the current role of AI in predicting and treating childhood obesity and its complications. A literature search was conducted on PubMed and Google Scholar for English-language articles published from 2015 onward. Search terms included combinations of keywords related to “obesity”, “pediatric”, “comorbidities” (e.g., MASLD, diabetes), and “artificial intelligence” (e.g., machine learning, deep learning, multi-omics). Eligible study types ranged from original articles to systematic reviews and clinical guidelines. By integrating multi-omic data (genome, epigenome, transcriptome, metabolome, microbiota) with socio-psychological metrics, AI can predict obesity risk and early complications. Machine learning (ML) and deep learning have successfully identified specific metabolites, gut flora alterations, neurological pathways, and metabolic SNPs linked to obesity susceptibility. Furthermore, ML-driven prognostic models enable risk assessment for MASLD or diabetes progression, while specialized software supports remote lifestyle monitoring and tailored dietary interventions. AI has the potential to revolutionize pediatric obesity management through precision medicine. However, challenges regarding data privacy, digital literacy, and equitable access persist. Because current evidence relies heavily on limited and heterogeneous pediatric datasets, large-scale, well-characterized, and externally validated cohorts are essential to establish the clinical applicability of AI models before routine implementation.

With global restrictions on in-feed antibiotics, sustainable alternatives are urgently needed to combat weaning-induced intestinal dysfunction in piglets. Fucoidan, a bioactive seaweed polysaccharide, exerts beneficial effects on gut health due to its immunomodulatory and prebiotic properties, but its mechanisms in the gastrointestinal tract of piglets remain unclear. This study investigated the effects of dietary fucoidan supplementation on growth performance, intestinal morphology, gut microbiota composition, and microbial metabolites in weaned piglets. The extracted fucoidan was characterized by a sulfate content of 23.7%, a molecular weight of 29.3 kDa, and fucose as the predominant monosaccharide. A total of 48 weaned piglets were randomly divided into two groups (n = 24 per group): a control group and a 500 mg/kg fucoidan treatment group. Growth performance was evaluated throughout the experiment. On day 28, jejunal and colonic tissues were collected to assess mucosal morphology (n = 6 per group), while cecal and colonic contents were collected for analysis of the gut microbiota and bacterial metabolites. Fucoidan supplementation significantly enhanced average daily gain (ADG, p < 0.05) and feed conversion ratio (FCR, p < 0.05) and mitigated diarrhea during the trial. Notably, piglets fed fucoidan exhibited increased villus height compared to controls (p < 0.05). Fucoidan modulated the gut microbiota by increasing cecal microbial diversity (p < 0.05) and shifting bacterial composition. These modifications involved an altered Bacteroidetes/Firmicutes ratio, as well as an enrichment of Prevotellaceae, Lactobacillus, and Lachnospiraceae (p < 0.05). Consistently, metabolite profiling analysis revealed increased cecal concentrations of lactate (p < 0.05) and butyrate (p < 0.05), which were positively associated with the growth of beneficial taxa. These findings demonstrate that fucoidan alleviates weaning-induced intestinal disorders by improving intestinal morphology and modulating gut microbiota and their metabolites. This study provides a strategy for utilizing marine-derived polysaccharides as functional feed additives to enhance animal health. Full article

For decades, industrial trans fatty acids (iTFAs) have remained a critical focus of the scientific community, the food industry, and regulatory authorities because of their well-established role in the development of cardiovascular diseases, metabolic disorders, and chronic systemic inflammation. Rather than providing a descriptive overview, this review critically synthesizes current evidence on the elimination of industrial TFAs by integrating health, technological, regulatory, and sustainability perspectives into a comprehensive interdisciplinary analysis. The review outlines the biochemical characteristics and dietary sources of trans fatty acid isomers, highlighting the continuing scientific debate regarding the differential health effects of industrially produced and naturally occurring ruminant-derived TFAs. It also examines the evolution of scientific evidence that led to major regulatory actions by international organizations, including the World Health Organization (WHO) and the European Commission, resulting in legally binding restrictions that have substantially reduced industrial TFA intake and improved public health. Particular emphasis is placed on the critical assessment of current fat reformulation strategies, considering not only their technological functionality but also their nutritional quality, long-term metabolic implications, and contribution to sustainable food systems. Full hydrogenation, fractionation, chemical and enzymatic interesterification, and oleogelation are comparatively evaluated with respect to their advantages, limitations, and potential technological, nutritional, and environmental trade-offs. In addition, lipid microencapsulation is discussed as an emerging strategy for protecting oxidation-sensitive polyunsaturated fatty acids (PUFAs), thereby facilitating their incorporation into functional foods while maintaining nutritional quality. Unlike previous reviews that primarily focus on health outcomes or individual processing technologies, this review systematically integrates the sustainability dimensions of alternative fat modification approaches, including resource efficiency, energy consumption, clean label product development, and circular economy principles. Furthermore, it identifies current knowledge gaps related to the long-term metabolic safety, industrial scalability, and environmental performance of emerging lipid technologies. By combining these complementary perspectives, the review provides a comprehensive interdisciplinary synthesis that supports evidence-based fat reformulation and offers practical guidance for researchers, food manufacturers, and policy makers seeking to develop safer, nutritionally improved, technologically functional, and environmentally sustainable lipid systems.
