Objectives: Atypical eating habits frequently characterize people with Autism Spectrum Disorder (ASD) from early infancy. Food selectivity, defined as a narrow variety of food intake and reticence to new food, is the most frequent feeding disorder in ASD. The objective of this study was to investigate the adaptive functioning and the behavioral profile of individuals with ASD with food selectivity (FS) in comparison to an ASD sample without food selectivity (NFS). Methods: We conducted a retrospective study on 286 children (mean age = 46.95 months) with a diagnosis of ASD; 43.3% of the sample had a history of food selectivity (FS), whereas 56.6% had no history of food selectivity (NFS). Results: No differences were found between the FS and NFS groups on cognition, autism symptom levels, and age. The FS group presented lower adaptive skills and greater behavioral problems in comparison to the NFS group. A worse clinical profile characterized children with more than one kind of food selectivity. Conclusions: The early identification and longitudinal evaluation of specific clinical and behavioral patterns in children with ASD associated with food selectivity could contribute to a better understanding of the relationship between autism symptoms and atypical eating habits.

Background: Atopic dermatitis (AD) is a common pediatric skin disease that is associated with other atopic comorbidities, all of which correlate with higher rates of neurocognitive alterations such as developmental delays and ADHD. Methods: We conducted a retrospective chart review from January 2022 through January 2024 and identified 79 children aged 0–5 years who were prescribed dupilumab in the Massachusetts General Brigham healthcare system. We defined the patient population (including demographics, atopic comorbidities, and neurocognitive burden), and assessed whether time to treatment access varied by patient or prescriber characteristics. Results: The mean age at dupilumab initiation was 3.4 years, and 62.0% of patients were male. The cohort was diverse (48.1% White, 25.3% Black, 16.5% Hispanic/Latino, 10.1% Asian/other), with 48.1% publicly insured. Atopic comorbidities were common: 64.6% had food allergies, 34.2% had asthma, and 10.1% had eosinophilic esophagitis (EOE); 73.4% had two or more atopic diagnoses. Neurodevelopmental disorders affected 43.0% of patients, with speech and language delay most frequent (25.3%) and higher rates among those with EOE (87.5% vs. 38.0%, p < 0.01). The mean time to dupilumab approval was 20.9 days, with dermatologists achieving faster approvals than other specialists (10.6 vs. 51.9 days, p < 0.001). Conclusions: Our findings reveal infrequently reported high rates of atopic and neurologic comorbidities in young children with AD and underscore the importance of coordinated inter-specialty collaboration to ensure timely access to dupilumab for these patients.

Astragalus membranaceus (A. membranaceus), a traditional Chinese medicine, has gained increasing recognition for its potential in treating central nervous system (CNS) disorders. This review aims to systematically integrate the mechanisms of action of A. membranaceus and its bioactive compounds on CNS diseases, with a focus on exploring its therapeutic potential and introducing related health food products. We conducted a comprehensive literature search in PubMed and Web of Science from January 2015 through July 2025. Our analysis reveals that A. membranaceus and its bioactive compounds, particularly A. membranaceus IV (AS-IV) and A. membranaceus polysaccharides (APS), exert multifaceted neuroprotective effects. These effects encompass the mitigation of neuroinflammation, oxidative stress, apoptosis, and ferroptosis, as well as the regulation of autophagy and protection of the blood–brain barrier. The therapeutic potential of A. membranaceus is linked to the modulation of key signaling pathways, such as NF-κB, Nrf2, and PI3K/Akt. Furthermore, based on the concept of “homology of medicine and food,” A. membranaceus is being developed into various health food formulations, offering a promising strategy for the adjuvant treatment and preventive care of CNS diseases. In conclusion, A. membranaceus represents a promising, multi-target pharmacological agent for CNS disorders, yet further high-quality clinical studies are warranted to validate its efficacy and safety in humans.

Background: Interleukin-1 (IL-1) inhibitors are approved for the treatment of various inflammatory diseases associated with immune system abnormalities. However, large-scale real-world studies to assess their security are still limited. Therefore, a pharmacovigilance study was conducted based on the data from the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). Methods: Adverse events (AEs) linked to IL-1 inhibitors were analyzed using the FAERS database from Q1 2004 to Q3 2024. Risk signals were identified through disproportionality analysis algorithms, including reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and multi-item gamma Poisson shrinker (MGPS). Results: Among 17,670 AE reports where an IL-1 inhibitor was the “primary suspected” drug, 27 significant system organ classes (SOCs) were identified. Notable signals included infections and infestations (ROR: 2.31, 95% CI: 2.25–2.37) and congenital, familial, and genetic disorders (ROR: 2.26, 95% CI: 2.05–2.48). At the preferred term (PT) level, 263 significant AE signals were detected, such as pyrexia (ROR: 5.27, 95% CI: 5.03–5.53), nasopharyngitis (ROR: 2.31, 95% CI: 2.10–2.54), and injection site erythema (ROR: 6.09, 95% CI: 5.67–6.55). Importantly, we also identified less common or previously unreported AEs, including cardiac disorders (e.g., postural orthostatic tachycardia syndrome with anakinra; pulmonary valve incompetence with rilonacept) and endocrine disorders (e.g., secondary adrenocortical insufficiency with canakinumab). Furthermore, 36.33% of cases emerged after more than 360 days of treatment with IL-1 inhibitors. Conclusions: This study revealed real-world safety data on IL-1 inhibitors, providing important insights to enhance the clinical use of IL-1 inhibitors and minimize potential AEs. Full article

Background: Obesity is increasingly recognized as a metabolic disorder driven by gut microbiota dysbiosis and chronic low-grade inflammation within adipose tissue. Emerging evidence highlights the gut–adipose tissue axis as a critical mediator of energy balance and metabolic regulation. Marine algae—rich in polysaccharides, polyphenols, and carotenoids—offer bioactive compounds that modulate gut microbial composition and generate beneficial metabolites termed “postbiotics.” Objective: This review aims to comprehensively summarize current advances in understanding how marine-algal-derived postbiotics influence the gut microbiota–adipose tissue axis and contribute to obesity prevention and management. Methods: A structured literature search was conducted across PubMed, Scopus, Web of Science, ScienceDirect, and SpringerLink for studies published between 2015 and October 2025. Eligible studies included in vitro, in vivo, and human trials examining the effects of marine-algal compounds on gut microbiota composition, short-chain fatty acid (SCFA) production, adipose inflammation, and metabolic outcomes. Results: Marine-algal polysaccharides (fucoidan, alginate, laminarin, carrageenan, and ulvan) act as fermentable fibers that enhance SCFA production and enrich beneficial taxa such as Akkermansia, Lactobacillus, and Bacteroides, while reducing endotoxin-producing bacteria. Polyphenols and carotenoids (fucoxanthin, phlorotannins, astaxanthin) directly target adipogenesis, oxidative stress, and adipose browning. Animal studies consistently demonstrate reduced body weight, improved insulin sensitivity, and decreased inflammation following algae supplementation. Human trials—though limited—confirm safety and show microbiota modulation with modest weight loss. Conclusions: Marine-algal-derived postbiotics represent a promising, natural, and sustainable strategy to target the gut microbiota–adipose tissue axis in obesity. They offer multi-targeted mechanisms through microbial and host pathways, supporting their integration into functional food and nutraceutical development. Further clinical research and regulatory standardization are warranted to translate these findings into evidence-based interventions. Full article

Cadmium (Cd) contamination in agricultural soils poses a significant risk to crop production and food safety. This study explored the role and mechanisms of manganese (Mn) in mitigating Cd toxicity using two rice genotypes: ZS97B (Cd-tolerant) and MY46 (Cd-sensitive). A hydroponic experiment was conducted under two Mn levels (0 and 100 µM) and three Cd levels (0, 5, 10 µM). Exposure to 10 µM Cd significantly inhibited plant growth and induced physiological disorders, with more severe effects observed in MY46 than in ZS97B. The addition of Mn markedly alleviated Cd toxicity, as reflected by increased antioxidant enzyme activities and reduced malondialdehyde (MDA) and hydrogen peroxide (H₂O₂) contents in both roots and shoots. Gene expression analysis showed that Mn addition up-regulated genes related to antioxidant enzymes and down-regulated key Cd uptake and transport genes, including OsNramp1, OsYSL2, OsMTP9, and OsHMA3. These changes contributed to enhanced antioxidant capacity and reduced Cd accumulation in rice plants under Cd stress. Our findings demonstrate that appropriate Mn application can effectively reduce Cd accumulation and alleviate toxicity in rice grown in Cd-contaminated environments. Full article

Objective: This narrative review summarizes current evidence on the associations between ultra-processed food (UPF) consumption, childhood and adolescent obesity, and functional gastrointestinal disorders (FGIDs), and examines the metabolic, inflammatory, microbial, and gut–brain mechanisms underlying these links. Methods: A comprehensive search of PubMed and Scopus identified articles published between January 2010 and September 2025. Eligible studies included human research in individuals aged 0–18 years; adult studies were considered when contributing relevant mechanistic insights. Of 335 records screened, 112 studies met the inclusion criteria and were synthesized narratively according to methodological appropriateness. Results: High UPF intake was consistently associated with increased adiposity, metabolic dysregulation, and greater cardiometabolic risk in youth. Children with overweight or obesity showed a higher prevalence of FGIDs compared with their normal-weight peers. Mechanistic evidence suggests that UPFs, rich in refined carbohydrates, unhealthy fats, and additives, may promote gut microbiota dysbiosis, impair intestinal barrier integrity, alter motility, and induce low-grade inflammation, thereby disrupting gut–brain signaling and contributing to FGID symptoms. Early-life and maternal UPF exposure may further increase susceptibility to metabolic and gastrointestinal disturbances through epigenetic and microbiome-mediated pathways. Conclusions: UPFs emerge as a shared etiological factor for obesity and FGIDs in childhood. This review contributes an integrated synthesis of epidemiological and mechanistic data while highlighting key research gaps, particularly the need for standardized methodologies and pediatric interventional studies to strengthen the evidence base.

Bipolar disorder (BD) is a severe psychiatric illness characterized by recurrent mood episodes and significant psychosocial impairment. Emerging evidence supports a bidirectional link between diet and mental health, with growing interest in nutritional psychiatry. This narrative review examines the psychological and psychiatric impact of diet in BD, focusing on biological mechanisms (gut–brain axis, neuroinflammation, oxidative stress, neurotransmitter synthesis, and HPA axis dysregulation) and the role of specific dietary patterns, including Western, Mediterranean, ketogenic, and anti-inflammatory diets. Key micronutrients such as omega-3 fatty acids, B-vitamins, magnesium, and vitamin D are explored in relation to mood regulation. This review also addresses psychological factors, including emotional eating, disordered eating behaviors, and the symbolic meaning of food in BD. Furthermore, it highlights the integration of nutritional psychoeducation into psychotherapy, the impact of comorbidities (e.g., obesity, metabolic syndrome), and the role of lifestyle factors such as sleep and physical activity. Despite promising findings, current research is limited by methodological heterogeneity. Future perspectives should include interdisciplinary, personalized interventions that incorporate nutritional strategies into standard care for BD. Full article

Background: Abiotic stresses, such as drought, salinity, temperature fluctuations, waterlogging, and heavy metal contamination, have a detrimental impact on plants, leading to reduced global agricultural productivity. The accumulation of cadmium (Cd) and arsenic (As) in agricultural soil, resulting from both natural and anthropogenic activities, poses significant threats to crop production and food safety. Dehydrins, also known as Group II Late Embryogenesis Abundant (LEA) proteins, are intrinsically disordered proteins that play crucial roles in protecting cellular structures during abiotic stress conditions. These proteins are considered promising candidates for enhancing plant tolerance to environmental stresses through their membrane-stabilizing and protective functions. Methods: This study evaluated the tolerance of Arabidopsis transgenic lines expressing a bacterial dehydrin gene (BG757) to Cd and As stresses using various physiological and biochemical parameters. Results: Compared with the wild-type (WT) control, the transgenic line (35S::BG757-1/Col-0) displayed significant increases in root and shoot growth upon exposure to Cd and As. Furthermore, transgenic plants exposed to heavy metal stress exhibited higher concentrations of chlorophyll, total protein, free proline, total flavonoid, and total phenolic content compared to WT plants. Likewise, transgenic plants showed higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and retained higher relative water content under stress conditions. Conclusions: Taken together, these findings suggest that bacterial dehydrins confer enhanced tolerance to heavy metal stress in transgenic Arabidopsis plants, highlighting their potential application in developing stress-resilient crops for contaminated environments.

Intestinal health is essential for maintaining systemic physiological balance through nutrient absorption, immune regulation, and host–microbiota interactions. Atractylodes macrocephala (Baizhu), a traditional medicinal plant long used for gastrointestinal dysfunction, has attracted growing interest because its polysaccharides (AMPs) show promises in intestinal disorders. In this review, we summarize preclinical studies on AMPs identified through searches of PubMed, Web of Science, ScienceDirect, Google Scholar and the China National Knowledge Infrastructure (CNKI), focusing on their extraction, purification, structural features and gut-related activities. Experimental evidence suggests that AMPs are metabolized by gut microbiota into short-chain fatty acids and other bioactive metabolites that regulate mucosal immunity, enhance epithelial barrier function and modulate host metabolic pathways. AMPs have been shown to promote the growth of beneficial taxa, restore dysbiotic communities, up-regulate tight junction proteins, suppress intestinal inflammation and modulate gut–brain axis signaling involved in intestinal motility and visceral sensitivity. These actions underlie their protective effects reported in models of irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), colorectal cancer, chemotherapy-induced mucosal injury, and metabolic-associated systemic inflammation. Overall, current data support AMPs as microbiota-modulating, immunomodulatory, epithelial-protective and neuro-regulatory agents with potential as functional food-derived interventions for intestinal health. In this review, we also highlight key limitations and priorities for future research on structure–function relationships and clinical translation. Full article

Background/Objectives: Chronic inflammatory diseases (CIDs) often present a preclinical phase influenced by genetic and environmental factors, including nutrition. Early dietary habits may modulate long-term health trajectories by shaping the intestinal microbiota. Previous work showed that weaning with fresh foods from the Mediterranean diet (MD) improved dietary habits and microbiota composition at 3 years of age. This study aimed to assess whether such benefits persist at 9 years. Methods: This long-term follow-up included 191 children (96 MD, 95 controls) from the original randomized cohort (ClinicalTrials.gov NCT05297357). The primary endpoint was adherence to MD (KidMed score ≥ 8). Secondary endpoints included BMI, incidence of CID, maternal dietary adherence, and intestinal microbiota composition in a subset of 36 children. Results: At 9 years, no difference was found in overall MD adherence (27.4% controls vs. 27.1% MD; p > 0.99) or BMI (17.7 vs. 18.1 kg/m²; p = 0.384). However, children from the MD group reported higher daily vegetable intake (71.9% vs. 51.6%; p = 0.005). Microbiota analyses revealed persistent differences between groups, with higher alpha diversity in the MD group. Although not statistically significant, the MD group showed lower prevalence of atopic dermatitis, allergic rhinitis, autism spectrum disorder, and ADHD. Maternal adherence to MD did not differ between groups. Conclusions: Early introduction of Mediterranean-style foods during weaning exerts lasting effects on dietary patterns and gut microbiota, with a potential protective trend against CID. While overall MD adherence converged between groups by 9 years, these findings suggest that early-life nutritional interventions may induce durable microbiome-mediated benefits and contribute to preventive strategies for chronic disease, warranting confirmation in larger, extended cohorts. Moreover, this study highlights the value of the collaboration between the Italian primary care pediatric system and the integration of the pediatric residency program, demonstrating a feasible and cost-effective methodology to generate large-scale prospective data within routine clinical practice. Larger studies and a longer follow-up period are necessary to confirm these results. Full article

In light of the increasing prevalence of metabolic disorders and immune-deficiency conditions, the development of complex plant-based biologically active supplements (BAS) represents a pressing challenge in modern food science. The aim of this study was to develop an immunomodulatory BAS using Jerusalem artichoke, sprouted oats, sprouted barley, and licorice root. Physicochemical, organoleptic, and microbiological analyses of raw materials and experimental samples were performed. It was established that sprouted grains are characterized by increased protein content (oats—12.64%, barley—11.87%) and elevated levels of amino acids (lysine—1.42% in sprouted barley). Jerusalem artichoke demonstrated high levels of dietary fiber (24.65%) and vitamin C (31.95 mg/100 g), while licorice root contained significant amounts of glycyrrhizic acid and vitamin B₂ (0.77 mg/100 g). The combination of Jerusalem artichoke, sprouted grains, and licorice root forms a solid foundation for the development of a complex BAS capable of normalizing metabolism and supporting the immune system, particularly in individuals with diabetes mellitus. This approach aligns with current trends in functional nutrition and contributes to import substitution and the advancement of Kazakhstan’s agro-industrial sector. Four BAS formulations were evaluated, and Sample 4 (Jerusalem artichoke—60 g, sprouted oats—12.5 g, sprouted barley—12.5 g, licorice root—15 g) was identified as optimal due to its balanced composition and high technological performance. It demonstrated good flowability (angle of repose—34°), satisfactory water-holding capacity (0.701 g/g), and the highest stability in organoleptic characteristics. The protein content of this sample was 11.97%, fiber—9.24%, and vitamin E—57.75 mg/100 g. The results confirm that the developed BAS is a valuable source of dietary fiber, amino acids, vitamins, and minerals, providing a pronounced synergistic immunomodulatory effect. The practical significance of the study lies in the potential application of the developed composition in the production of functional foods aimed at metabolic correction and diabetes prevention.

Background: Autism spectrum disorder (ASD) constitutes a heterogeneous neurodevelopmental condition frequently accompanied by considerable disturbances in feeding behavior and nutritional balance. These difficulties arise from complex and multifactorial mechanisms, exerting a significant impact on physical health, metabolic homeostasis, and psychosocial functioning. The present review aims to provide a critical synthesis of current evidence regarding the underlying biological and behavioral mechanisms of feeding difficulties in ASD and to delineate the spectrum of comorbid eating disorders within this population. Methods: A narrative review of the peer-reviewed scientific literature was undertaken, emphasizing studies investigating the interrelationship between ASD and nutritional functioning in pediatric and adolescent populations. Particular focus was placed on research exploring sensory processing abnormalities, gut microbiota alterations, and the clinical manifestation of eating disorders in individuals with ASD. Results: The analysis revealed that sensory hypersensitivity, behavioral inflexibility, and disturbances within the gut–brain axis constitute principal determinants of atypical eating patterns in ASD. Individuals on the autism spectrum frequently exhibit pronounced food selectivity, neophobia, and symptoms consistent with Avoidant/Restrictive Food Intake Disorder (ARFID). Furthermore, an increased prevalence of anorexia nervosa and orthorexia nervosa has been documented, likely reflecting shared cognitive and behavioral features with ASD. “Emotional eating” tendencies and a marked preference for high-caloric, energy-dense foods—often potentiated by psychopharmacological treatment and reduced physical activity—further contribute to an elevated risk of overweight and obesity. Conclusions: Children and adolescents with ASD display a bimodal distribution of body mass, encompassing both undernutrition and obesity, indicative of a multifaceted interplay among sensory, behavioral, cognitive, and metabolic determinants. A comprehensive understanding of this heterogeneity is crucial for the development of individualized, evidence-based interventions integrating nutritional management with behavioral and psychotherapeutic approaches.

Background/Objectives: Obesity is a multifactorial disease associated with increased consumption of ultraprocessed foods and reduced intake of unprocessed foods. Binge eating, one of the most prevalent eating disorders among adolescents, is closely linked to obesity. Food intake is regulated by both the hedonic system, responsible for reward responses, and the physiological system, which controls hunger and satiety through hormones, such as ghrelin and leptin. The present study aimed to investigate associations between the intake of unprocessed and ultraprocessed foods, neuroendocrine mediators of appetite regulation, and binge eating in adolescents with obesity. Methods: This cross-sectional study included 96 adolescents with obesity who were recruited in São Paulo, Brazil, between 2010 and 2012. Anthropometric and body composition assessments were performed. Binge eating symptoms were evaluated using the binge eating scale (BES), and dietary intake was assessed with a validated Food Frequency Questionnaire, with items classified according to the Nova system. Frequency data were converted into annual consumption scores. Serum levels of ghrelin, leptin, neuropeptide Y (NPY), agouti-related peptide (AgRP), melanin-concentrating hormone (MCH), and alpha-melanocyte-stimulating hormone (α-MSH) were analyzed. Results: Lower consumption of unprocessed foods was associated with higher ghrelin concentrations (p = 0.023), accompanied by a greater percentage of body fat (p = 0.047) and a reduced percentage of lean mass (p = 0.047) compared with adolescents in the second tertile. AgRP was a positive predictor of annual consumption score of ultraprocessed food (β = 0.30; p = 0.04), independent of age, body fat, and binge eating symptoms. Conclusions: In conclusion, lower intake of unprocessed foods was associated with alterations in orexigenic and anorexigenic mediators, suggesting that dietary patterns in adolescents with obesity may influence the neuroendocrine mediators of appetite regulation.

Background: Autism Spectrum Disorder (ASD) is a multifactorial neurodevelopmental condition in which genetic predisposition interacts with environmental factors. Among these, the gut microbiota has emerged as a crucial modulator of the microbiota–gut–brain axis (MGBA), influencing neuroinflammation, neurotransmission, and behavior. This review aims to provide an updated and integrative overview of the relationship between gut microbiota, diet, and neurodevelopment in ASD. Methods: A comprehensive search was conducted in PubMed, Scopus, and Web of Science for articles published between 2010 and 2025. Original studies, systematic reviews, and meta-analyses in English were included. Results: Evidence from human and animal studies supports a strong association between gut dysbiosis and ASD-related behaviors. Alterations in microbial composition, characterized by reduced Bifidobacterium and Prevotella and increased Clostridium spp., have been linked to impaired intestinal barrier function, chronic inflammation, and altered production of microbial metabolites such as short-chain fatty acids and tryptophan derivatives. Discussion: Maternal dysbiosis, nutritional imbalances, and perinatal stressors may further modulate fetal neurodevelopment through immune and epigenetic pathways. Emerging data suggest that dietary modulation, targeted nutritional interventions, functional foods, prebiotics, probiotics, and postbiotics could help restore microbial balance and improve neurobehavioral outcomes. Conclusions: The gut microbiota represents a key biological interface between environment, metabolism, and neurodevelopment. It is, therefore, necessary to transform current knowledge about the microbiota and neurodevelopment into clinical, social, and health actions that offer real solutions to people with ASD and their families. From this perspective, focusing on prevention, promoting healthy lifestyles, and integrating new technologies represent the true tools for building a more sustainable and inclusive healthcare system.
