Inflammatory Bowel Diseases (IBDs), including Crohn’s disease (CD) and ulcerative colitis (UC), have become a growing global health concern in children and adolescents. Pediatric-onset IBD presents unique challenges compared with adult-onset forms, including more extensive disease, impaired growth, delayed puberty, and psychosocial difficulties. While biologic and targeted therapies have advanced disease control, nutritional interventions remain a central component of management. Exclusive enteral nutrition (EEN) is recognized as the first-line therapy for inducing remission in pediatric CD, offering comparable efficacy to corticosteroids with additional benefits for mucosal healing, nutritional status, and growth. Modified dietary approaches, such as partial enteral nutrition and the Crohn’s Disease Exclusion Diet (CDED), show promise for improving adherence and maintaining remission. However, dietary restrictions may lead to deficiencies and psychosocial stress, underscoring the importance of individualized, dietitian-supervised care. The role of nutrition in UC is less defined, but balanced, anti-inflammatory dietary patterns appear beneficial. This narrative review summarizes current evidence on nutritional strategies in pediatric IBD, highlighting their therapeutic potential, limitations, and integration with pharmacologic treatment within a multidisciplinary framework aimed at optimizing outcomes and quality of life.

Background: The pursuit of longevity has long been central to nutritional science, with growing evidence underscoring the profound influence of dietary patterns on lifespan and overall health. While various diets have been associated with improved well-being, their comparative effects on longevity remain to be synthesized comprehensively. Main Findings: This review examines the scientific evidence linking major dietary patterns such as the Mediterranean, DASH (Dietary Approaches to Stop Hypertension), plant-based, Blue Zones, intermittent fasting, caloric restriction, and Nordic diets, to longevity and mortality outcomes. The Mediterranean and DASH diets consistently demonstrate reduced cardiovascular and all-cause mortality, while plant-based and Blue Zones diets emphasize whole, minimally processed foods that enhance metabolic and cardiovascular health. Intermittent fasting and caloric restriction emerge as metabolic modulators with anti-aging potential. The Nordic diet, rich in locally sourced foods like berries and fish, also contributes to lower mortality and improved cardiovascular function. Conclusions: This paper uniquely integrates comparative insights from diverse dietary frameworks, emphasizing their shared principles of nutrient density, moderation, and metabolic balance. By adopting evidence-based elements from these dietary models, individuals can optimize health span and longevity, reinforcing the pivotal role of diet as a cornerstone of preventive and personalized nutrition.

Background: Celiac disease (CeD) is a chronic, immune-mediated enteropathy triggered by gluten ingestion in genetically predisposed individuals. While a lifelong gluten-free diet (GFD) remains the cornerstone of treatment, inadequate follow-up can lead to persistent symptoms, nutritional deficiencies, and long-term complications. Aim: This narrative review summarizes best practices in celiac disease follow-up, with emphasis on multidisciplinary, nutritional, clinical, and preventive care strategies to optimize long-term outcomes. Main Findings: High-quality follow-up requires coordinated care involving gastroenterologists, dietitians, primary care providers, and other specialists. Nutritional challenges of the GFD include high cost, limited fortification, suboptimal nutrient content, and increased risk of obesity and metabolic dysfunction. Patients also face psychosocial and behavioral burdens such as anxiety, social isolation, and disordered eating. Evidence-based strategies for follow-up include structured clinical and serologic monitoring, laboratory assessments, bone health evaluation, cancer risk reduction, and preventive care. Novel tools such as gluten immunogenic peptide testing, digital health platforms, and artificial intelligence are emerging as adjuncts to clinical management. Implications: Structured, patient-centered follow-up that integrates medical, nutritional, and psychosocial dimensions is essential to achieving mucosal healing, maintaining long-term health, and improving quality of life in individuals with CeD.

Background/Objectives: Human breast milk is a mammary gland secretion with a dynamic composition, containing important bioactive factors for infant growth. Epigenetic factors, like microRNAs, are found in breast milk and can regulate gene expression and, thus, infant growth. Obesity is, among others, a major global health concern with long-term consequences, making its prevention during early life a public health priority. Maternal lifestyle factors, including diet and body weight status, may influence infant growth patterns and susceptibility to obesity. The aim of this review is to explore the hypothesis that miRNA content in breast milk might be influenced by maternal obesity, eventually affecting the obesity risk in offspring. Methods: This systematic review was carried out in line with the PRISMA 2020 statement and included observational (cohort) studies that met the inclusion criteria and compare the expression of miRNAs in OW/OB lactating mothers and associate this to the obesity development in the offspring. Results: According to the included studies, the most common miRNAs are miR-148a, miR-30 family, and miR-let7 family, with miR-30b and miR-let7a among the most discussed that participate in adipogenesis. Some of these miRNAs secreted in breast milk pass on a genetic predisposition for obesity to the next generation, while others provide a protective role against obesity in the offspring. Conclusions: Eventually, even though individual miRNAs may fluctuate, the overall miRNA profile remains stable. The findings underscore the importance of balanced maternal nutrition and optimal health during lactation, both for supporting healthy infant development and for potentially reducing the risk of obesity later in life.

Improving livestock nutrition with natural supplements can enhance productivity and meat quality. This study evaluated whether a clayey micromineral compound (CMC) in lamb diets improves feed efficiency, health, and meat traits. Twenty-four 60-day-old Dorper/Santa Inês crossbred lambs (28.41 ± 4.147 kg initial weight) were randomly assigned to four CMC doses (0%, 0.4%, 0.8%, or 1.2% of dry matter intake/day) for 90 days, following a 15-day adaptation. The lambs were individually housed, with daily feed intake monitoring, weekly weight measurements, and blood analyses at the start and end. On day 89, rumen fluid was sampled for digestion analysis, and post-mortem evaluations were used to assess meat quality and rumen health. The results showed that 0.8% CMC optimized fat and fiber digestion (p < 0.05), while higher doses linearly improved meat color intensity (p < 0.05). Blood tests indicated better liver function at intermediate doses (p < 0.05). However, the CMC did not affect overall growth, feed intake, or carcass traits. The supplement was safe but provided selective benefits. These findings suggest that CMCs could enhance feed efficiency and meat appeal, although further research is needed to refine dosing for maximum impact. Full article

Under the spatial distribution of water resources, with more water resources in the southern regions and less in the northern regions, and the “north–south grain transport” pattern, calculating the virtual water flow in food trade between provinces in China and analyzing its sustainability is crucial for ensuring the country’s water resources and food security. By considering various products and consumption types, the virtual water flow in inter-provincial grain trade is estimated using the Minimum Transport Cost Method and the Penman-Monteith formula. The sustainability of this virtual water flow is evaluated at the provincial level. (1) The results show that the top three provinces with the largest net virtual water outflow from inter-provincial grain trade are Heilongjiang, Henan, and Anhui, with net outflows of 43.166 billion m³, 18.974 billion m³, and 13.089 billion m³, respectively. The top three provinces with the largest net virtual water inflows are Hebei, Guangxi, and Liaoning, with net inflows of 18.875 billion m³, 10.076 billion m³, and 8.795 billion m³, respectively. (2) The largest inter-provincial virtual water flow occurs from Henan to Hebei (15.06 billion m³), followed by Inner Mongolia to Hunan (9.57 billion m³), and Heilongjiang to Hubei (9.04 billion m³). (3) Overall, the current pattern of virtual water flow in China’s grain trade is sustainable, though several exporting provinces are under greater stress. In the actual scenario, the average water resource pressure index across all provinces is 0.43, 17.31% lower than the average of 0.52 in the scenario without inter-provincial grain trade. Compared with the scenario without inter-provincial grain product trade, in the actual scenario, Heilongjiang, Jilin, and Inner Mongolia show a higher increase in water resource pressure index, with increases of 94.74%, 73.68%, and 48%, respectively; Beijing, Shanghai, and Qinghai show a greater decrease in water resource pressure index, with reductions of 94.64%, 79.41%, and 66.67%, individually. And then, efforts should be made to adjust and optimize the structure of grain production and circulation; provinces with virtual water net outflow (such as Heilongjiang, Henan, Anhui, etc.) need to adjust their grain cultivation types and grain export structures.; provinces with virtual water net inflow (such as Hebei, Guangxi, Liaoning, etc.) can appropriately expand the scale of grain cultivation, while adjusting their diets to reduce the demand for water-intensive grains.

The environmental impact of companion animals has received little scientific attention compared to that of livestock, even though the global dog population is rapidly increasing, particularly in urban areas. This review addresses the overlooked contribution of dogs to environmental emissions, focusing on feces, urine, packaging waste, and other care-related by-products. The current knowledge from livestock research provides useful analogies for understanding nutrient excretion and gaseous emissions from dog feces, and data on nitrogen and phosphorus inputs highlight their potential to pollute soil and water. We also examine the role of plastic waste from food packaging, waste bags, and accessories, which can degrade into microplastics, and discuss recent developments in biodegradable materials. Evidence shows that owner choices—such as diet composition, protein sources, and product selection—directly affect the environmental pawprint of dogs. Mitigation strategies include optimizing diets to reduce nutrient excretion, applying feed additives developed for livestock, and improving waste management through composting or the use of emission-reducing amendments. In conclusion, dogs should no longer be viewed merely as individual household companions but as a population with a measurable environmental pawprint. Including dogs in emission reporting systems would provide a more accurate basis for mitigation policies and sustainable urban planning. Full article

The European grayling is an ecologically and recreationally important salmonid fish species. However, its wild populations have declined in recent years across Europe due to habitat degradation, predation and overexploitation. Unfortunately, conservation measures such as stocking with hatchery-reared fish may threaten the genetic integrity of native populations. The use of triploid all-females, which display markedly reduced fertility, offers a potential solution to this problem. While protocols for inducing triploid and gynogenetic development of the species exist, an effective method for producing neo-males, essential for large-scale triploid female stock production, is still lacking. In the present study, the potential suitability of 11β-hydroxyandrostenedione (OHA) and 17α-methyltestosterone (MT) for masculinization of the European grayling was investigated, aiming to provide preliminary data to support the future development of a reliable biotechnique for neo-male production in this species. Pilot trials of hormonal masculinization were conducted by feeding 20-day post-hatch fry with diets supplemented with OHA (10 mg/kg—OHA_10ppm, 20 mg/kg—OHA_20ppm) or MT (3 mg/kg—MT_3ppm, 6 mg/kg—MT_6ppm) for ~80 days. In the OHA-treated groups, the proportion of externally male-like individuals ranged from 66.7% (OHA_10ppm) to 76.6% (OHA_20ppm). However, some of these specimens were found to be genetically female with ovaries (4.5% and 28.8%, respectively), which indicated a dissociation between external dimorphism and gonadal development. In turn, MT treatments resulted in strong disruption of the female gonads with the intersex individuals comprising 28.6% (MT_3ppm) and 57.1% (MT_6ppm), indicating that the applied hormonal treatment was insufficient for complete masculinization. The results indicate that androgen-mediated neo-male induction by OHA and MT is possible in the species but requires optimization of dose, timing and delivery, potentially combining embryonic immersion with prolonged dietary administration.

Mitigating stress responses is crucial for maintaining optimal productivity and profitability in modern poultry production. The effects of early feed withdrawal (EFW) and vitamin C (Vit C) supplementation, both individually and in combination, on heat-stressed broilers’ productivity, stress responses, and metabolic markers were investigated. In total, 240 newly hatched Cobb-500 male chicks were randomly distributed to four treatment groups (six replicates × 10 birds per group). A basal diet was offered to the control group; meanwhile, the EFW group underwent a 24 h early feed withdrawal on day four of age. The Vit C group was given 200 mg/kg vitamin C daily, and the EFW + Vit C group received both interventions. The study was executed under hot summer conditions, where the average minimum and maximum temperature-humidity Index (THI) were 29.15 ± 0.78 and 33.34 ± 0.76, respectively. The results demonstrated a superior stress-mitigating effect when EFW was combined with Vit C supplementation, leading to a significant improvement in productive parameters and elevated blood metabolic hormone levels. Additionally, total antioxidant capacity was enhanced, hepatic endogenous antioxidant enzyme expression was upregulated, and stress biomarkers were reduced. Furthermore, the economic efficiency indicators were significantly improved with EFW, and when EFW was combined with Vit C addition. These findings suggest that integrating multiple stress mitigation strategies, such as EFW and Vit C supplementation, may be more effective in relieving the adverse effects of heat stress by restoring homeostasis and optimizing broilers’ productivity and profitability.

This study investigated the effects of inulin concentration and ultrasonic homogenization on the particle size distribution and microstructure of oil-in-water emulsion gels stabilized with psyllium husk. These gels were then incorporated into meal purees formulated for individuals with dysphagia. Under ultrasound treatment, an increase in inulin from 0% to 20% reduced the average droplet size from 14.98 μm to 1.58 μm, indicating a synergistic effect between ultrasound treatment and inulin in reducing and stabilizing droplet size. The optimal formulation under ultrasound was 20% (w/w) inulin. Scanning electron and polarized light microscopy confirmed that ultrasonic homogenization improved emulsion integrity by minimizing droplet size and promoting encapsulation. Inulin-rich emulsion gels, when added to purees, reduced structural voids, improved matrix cohesion, and lowered expressible fluid content. Enzymatic assays showed enhanced inhibition of α-amylase and α-glucosidase, indicating increased resistance to oral enzymatic degradation. Importantly, substituting emulsion gels at 10% (w/w) did not compromise puree firmness. All formulations met International Dysphagia Diet Standardization Initiative (IDDSI) Level 4 requirements, confirming their suitability for individuals with oropharyngeal dysphagia (OD). These findings demonstrate the potential of psyllium husk-stabilized emulsion gels as innovative texture-modifying agents for dysphagia-friendly food development. Full article

Olive flounder (Paralichthys olivaceus), a key aquaculture species in East Asia, is prone to stress and bacterial diseases under intensive farming. Antibiotics are often used to control these problems, but their overuse promotes resistance and threatens sustainability. To provide safer alternatives, this study evaluated the strain-specific effects of dietary probiotics on growth, immunity, and disease resistance in olive flounder. A five-week feeding trial was conducted to evaluate the effects of three isolates—Bacillus subtilis, Enterococcus faecium, and Pediococcus pentosaceus—on growth, blood biochemistry, immune responses, and resistance against Edwardsiella tarda. Each strain was incorporated individually into a basal diet. After the feeding trial, probiotic supplementation improved growth performance. P. pentosaceus significantly increased final body weight and other growth indices (p < 0.05), while E. faecium yielded the lowest feed conversion ratio. Plasma glucose was markedly reduced in the E. faecium and P. pentosaceus groups (p < 0.001), whereas other biochemical indices remained stable. Phagocytic activity was significantly increased in the B. subtilis (p < 0.05) and P. pentosaceus (p < 0.01) groups, while lysozyme activity was significantly elevated in the E. faecium (p < 0.01) and P. pentosaceus (p < 0.05) groups. Following the E. tarda challenge, survival improved in all probiotic-fed groups (22.5–28.9%) compared with the control (11.5%). These findings demonstrate complementary, strain-specific benefits: P. pentosaceus enhanced growth, E. faecium improved feed efficiency and disease resistance, and B. subtilis stimulated immune responses. Validation under farm conditions and exploration of multi-strain formulations are warranted to optimize probiotic use in olive flounder aquaculture. Full article

Celiac disease (CeD) is a chronic autoimmune enteropathy triggered by dietary gluten in genetically predisposed individuals. Along with other disorders such as non-celiac gluten/wheat sensitivity and gluten allergy, adherence to a strict gluten-free diet (GFD) is required as the only effective treatment for CeD. To this end, and partially due to the burdensome nature and limited efficacy in some patients of a GFD, significant research into alternative therapies has been catalyzed. This review gives a perspective on current and emerging treatment strategies targeting different aspects of CeD pathogenesis. These include gluten-degrading enzymes (e.g., AN-PEP, Latiglutenase, Zamaglutenase), gluten-sequestering agents (e.g., AGY-010, BL-7010), modulators of intestinal permeability (e.g., Larazotide acetate, IMU-856), immune-modulating agents (e.g., ZED1227, AMG 714, EQ102), and strategies for immune tolerization (e.g., TAK-101, KAN-101, Nexvax2). Newer approaches are also targeting probiotics to modulate the gut microbiota (e.g., VSL#3, Lactobacillus plantarum HEAL9), nutraceuticals (e.g., polyphenols, vitamins), or food modifications to remove the gluten from naturally gluten-containing foodstuffs (e.g., gluten transamidation, Gluten Friendly™ technology). Despite encouraging results in preclinical and clinical trials, no treatment has yet been conclusively proven to serve as an effective alternative to the GFD. Continued research is essential to validate efficacy, optimize dosing, and ensure safety in broader patient populations. Here, we provide a comprehensive overview of the therapeutic landscape for CeD, analyze the main strengths and limitations of each treatment and highlight promising directions for future management of CeD, altogether evidencing the urgent need to develop effective alternatives for these patients.

Carotenoids are lipophilic pigments naturally occurring in plants and, to a lesser extent, in certain non-photosynthetic organisms. They play a critical role in human health due to their antioxidant and immunomodulatory properties. Key carotenoids such as β-carotene, lycopene, lutein, and zeaxanthin are capable of neutralizing reactive oxygen species, thereby mitigating oxidative stress—a major contributor to the onset and progression of chronic diseases. These compounds also modulate immune responses by influencing lymphocyte proliferation, enhancing natural killer cell activity, and regulating the production of pro- and anti-inflammatory cytokines. Such immunomodulatory effects are associated with a reduced risk of infectious diseases and have shown potential protective roles against inflammatory conditions, cardiovascular and neurodegenerative disorders, and certain types of cancer. Moreover, diets rich in carotenoids are linked to improved immune status, particularly in vulnerable populations such as the elderly and immunocompromised individuals. Despite strong epidemiological evidence, clinical trials involving carotenoid supplementation have produced mixed results, indicating that their effectiveness may depend on the broader dietary context and interactions with other nutrients. In summary, carotenoids are important dietary compounds that contribute to immune regulation and the prevention of various diseases, although further clinical research is needed to determine optimal intake levels and assess their full therapeutic potential.

Dyslipidemia is a major modifiable risk factor in patients with acute coronary syndrome (ACS), and effective management is essential to reduce the risk of recurrent cardiovascular events. Recent guidelines emphasize early, intensive lipid-lowering therapy (LLT) and increasingly recommend combination regimens to achieve ambitious low-density lipoprotein cholesterol (LDL-C) targets. This review evaluates current evidence and recommendations for dyslipidemia treatment in ACS, with a focus on the rationale, timing, and selection of combination therapy. We conducted a comprehensive review of recent clinical guidelines, randomized controlled trials, and observational studies addressing lipid management in ACS. The analysis included data on LDL-C targets, efficacy and safety of high-intensity statins, adjunctive non-statin therapies (ezetimibe, PCSK9 inhibitors), and the impact of dietary interventions. Early and intensive LLT, initiated within 24–48 h of ACS, is associated with significant reductions in recurrent events and mortality. High-intensity statins (atorvastatin 40–80 mg or rosuvastatin 20–40 mg) are first-line, with combination therapy (statin plus ezetimibe and/or PCSK9 inhibitor) recommended for patients not achieving LDL-C < 1.4 mmol/L (<55 mg/dL) or >50% reduction from baseline. Evidence supports further LDL-C lowering (<1.0 mmol/L) in very high-risk patients. The Mediterranean and DASH diets provide additional benefit in lipid profile optimization and risk reduction. Statins also confer pleiotropic effects, including anti-inflammatory and plaque-stabilizing actions. Recent studies and real-world data confirm the efficacy and safety of combination approaches but highlight the need for individualized therapy based on residual risk, comorbidities, and tolerability. Achieving guideline-recommended LDL-C targets in ACS patients often requires early initiation of combination lipid-lowering therapy. Optimal management should be individualized considering both LDL-C levels and broader risk profiles. Ongoing research is needed to refine patient selection for combination therapy and to integrate novel agents into clinical practice. Full article

Healthy nutrition is of great importance to maintain the physical and mental health of individuals. In recent years, products such as snack bars have become widely used to encourage healthy eating habits. This study compared the environmental footprints of four snack bar prototypes that adhere to the Mediterranean diet (MD) through a life cycle assessment (LCA). LCA is used to calculate an environmental footprint, encompassing six impact categories: Global Warming Potential (GWP), Abiotic Depletion (AD), Human Toxicity (Cancer (HTC) and Non-Cancer Effects (HTNC)), land use (LU), and water use (WU). The total impacts were as follows (prototypes 1–4, respectively): GWP 0.221/0.224/0.234/0.194 kg CO₂-eq; AD 2.35/2.87/2.63/2.01 MJ; HTC 9.13 × 10⁻¹⁰/7.69 × 10⁻¹⁰/9.82 × 10⁻¹⁰/9.88 × 10⁻¹⁰ CTUh; HTNC 1.03 × 10⁻⁸/1.51 × 10⁻⁹/4.16 × 10⁻⁹/3.03 × 10⁻⁹ CTUh; LU 14.8/21.6/21.8/10.8; WU 0.132/0.287/0.198/0.068 m³. Prototype 4, which yielded the lowest value across four indicators (GWP, AD, LU, and WU), is the most environmentally favorable. A range of 89–91% of the GWP originates from raw material production, while the share attributed to transportation is 3–4%. Nuts and dried fruit contents are decisive for WU and LU. The findings suggest that environmental impacts are highly sensitive to ingredient composition and agricultural inputs, and that selecting raw materials and optimizing the supply chain is critical for mitigation.
