Shellfish are ubiquitous inhabitants of water environments and an important food source. Their presence in habitats affected by human activities and bioaccumulation potential support their use as indicators of contamination. Using these organisms as bioindicators may provide a simple, cost-effective alternative for monitoring contamination risk without requiring complex sample preparation and analytical procedures. However, there is no consensus on biomarkers, species selection, or standard methodologies. This systematic review explores the significance of shellfish as bioindicators, the methodologies employed, and the interactions between contaminants and host response. Research strategy and selection criteria followed PRISMA and SPICE guidelines. Peer-reviewed papers were obtained from Scopus, Pubmed and Google Scholar using the keywords: shellfish, bioindicator, environmental, contaminant, and host response. Out of 3050 results, 20 studies were selected after a rigorous, unbiased process. These studies spanned 14 countries, assessing 26 shellfish species, 24 contaminants, and 35 effects. A wide range of biomarkers was identified, reflecting changes in water condition due to contaminants or adverse environmental parameters. Results indicate that shellfish are highly sensitive to minor environmental changes, making them reliable bioindicators of water quality and potential risks of consumption from contaminated sites. This study highlights the need for standardized protocols to enable consistent shellfish-based monitoring of water conditions worldwide.

Bovine tuberculosis (bTB) is one of the major zoonotic concerns of the world, as milk and meat from cattle are major products for human consumption. Bovine tuberculosis not only affects the health of cattle and poses an imminent zoonotic threat, but also causes significant economic loss in both developed and developing countries. This systematic review reports the prevalence of Mycobacterium tuberculosis complex (MTBC) organisms in slaughtered cattle showing tuberculosis-like lesion (TBL) with available literature worldwide. Appropriate keywords were used to search various databases to collect articles pertaining to slaughterhouse studies. Bovine TB prevalence, based on the prevalence of MTBC organisms in slaughtered cattle showing TBL by culture, microscopy, PCR and spoligotyping, was assessed in each study using a random-effects model and standardized mean with 95% confidence interval (CI). Heterogeneity was assessed by the I2 statistic. Publication bias was evaluated using funnel plots. Out of 72 hits, 37 studies were selected based on title and abstract. Ten articles were excluded due to lack of desired data, and 27 studies were included in the final analysis. From the selected articles, it was found that 426 [95% CI: 302-560] per 1,000 slaughtered cattle with TBL were positive for the presence of MTBC organisms. The sensitivity analysis showed that no individual study alone influenced the estimation of pooled prevalence. The prevalence of MTBC organisms in slaughtered cattle showing TBL by culture, microscopy, PCR and spoligotyping was 474[95% CI: 342-610], 385 [95% CI: 269-515], 218 [95% CI: 132-338], 326 [95% CI: 229-442], respectively, per 1,000 slaughtered cattle. Most of the slaughtered cattle were from the same locality as the slaughterhouse. The results obtained in this study suggest that abattoir monitoring can give an estimate of the prevalence of bTB in that locality. This study also emphasizes the need to test cattle and animal handlers who were in contact with bTB-positive cattle. © 2021 Wiley-VCH GmbH.

This experiment was designed to study the effects of a hydroalcoholic fruit extract from Withania coagulans (WC) and α-tocopherol acetate (α-Toc) in diets containing oxidised oil on growth performance, immune response and antioxidant indices of broiler chickens. The experiment was arranged 2 × 3 × 2 factorial comprising the oxidised oil (0% and 2% diet), WC (0, 100 and 200 mg/kg diet) and α-Toc (0 and 200 mg/kg diet). A total of 600 1-day-old male broiler chickens of the Ross strain were randomly allocated to 12 treatments with 5 replicates of 10 birds each. On day 42, one bird from each replicate was sacrified to measure the lymphoid organ weights, intestinal morphometric characteristics, and malondialdehyde content in the thigh meat. Dietary inclusion of oxidised oil significantly reduced the body weight gain in birds receiving no dietary WC (p < 0.05). In contrast, dietary supplementation of WC at 100 mg/kg diet in birds fed with the diets lacking in WC and oxidised oil resulted in significant increase in body weight gain (p < 0.05). Dietary supplementation of WC significantly increased the total anti-sheep red blood cell titre (p < 0.01). The birds fed with the dietary oxidised oil revealed significantly higher values of malondialdehyde and lower glutathione peroxidase and superoxide dismutase activities (p < 0.05). Feeding diets containing WC resulted in a significant decrease in malondialdehyde content in thigh meat while conversely, increased the glutathione peroxidase and superoxide dismutase activities (p < 0.05). The findings indicated that the dietary inclusion of WC could be recommended as a potent alternative to synthetic compounds in order to improve broilers performance, immunity and meat quality under oxidative stress conditions.

This study aimed to investigate the effects of quercetin and rutin (the glycoside form of quercetin) on growth performance, organ indices, meat quality, serum biochemistry, intestinal morphology, and cecal microbiota of broilers under high stocking density, and compared their differential effects. A total of 480 one‑day‑old male Cobb500 broilers were randomly allocated to 6 treatment groups (6 replicates per group): a control group reared at 14 broilers/m², a high stocking density group at 20 broilers/m², and four high stocking density groups fed diets supplemented with 400 ppm or 800 ppm quercetin or rutin, respectively. The results of this study show that, compared with the control group, high stocking density, as well as supplementation with 400 ppm quercetin, 400 ppm rutin, and 800 ppm rutin, significantly reduced FI and BWG throughout the entire trial period. However, supplementation with 800 ppm quercetin showed a trend toward alleviating the reduction in FI and BWG caused by high stocking density. Supplementation with quercetin significantly increased the meat color of the pectorales at 45 min postmortem, whereas rutin supplementation significantly reduced drip loss of the pectorales at 24 h postmortem. Furthermore, quercetin and rutin supplementation significantly increased the chao1 index, enriched the beneficial intestinal bacteria Alistipes and Faecalibacterium, and reduced the relative abundance of the harmful bacterium Streptococcus at the genus level. In conclusion, quercetin and rutin differentially improved growth performance, meat quality, and cecal microbiota of broilers reared under high stocking density. © 2026 The Authors.

Kampung Unggul Balitbangtan (KUB) chicken is a superior Indonesian native breed with high adaptability, good growth potential, and desirable meat quality. Nutritional strategies such as multienzyme supplementation are increasingly applied to improve productivity and meat quality without altering basal diet composition. This study investigated the effects of dietary multienzyme supplementation, consisting of phytase and protease, on growth performance, carcass characteristics, organ development, meat quality, and muscle-related gene expression in KUB chickens. Sixteen one-day-old male KUB chicks were randomly allocated to four dietary treatments: a control diet without multienzymes and three diets supplemented with phytase (200 mg/kg) combined with protease at 300, 500, or 700 mg/kg of feed. Growth performance parameters were measured up to 45 days of age, followed by carcass evaluation, organ weight analysis, meat quality assessment, and transcriptomic and quantitative real-time PCR analyses of breast muscle tissue. Multienzyme supplementation significantly improved final body weight and feed conversion ratio, particularly during the finisher phase, while reducing feed intake at higher enzyme inclusion levels. Carcass percentage and breast weight were enhanced in multienzyme-treated groups, accompanied by favorable changes in digestive and immune organ development. Meat quality analysis showed increased water-holding capacity, reduced cooking loss, and improved color characteristics, notably higher redness and lower yellowness values. Transcriptomic profiling and gene expression analysis revealed significant modulation of key muscle growth-related genes, including ACTA1, MYBPC1, TGFβ2, IGF2, and MYH9, indicating adaptive transcriptional responses associated with improved nutrient utilization rather than direct structural muscle alterations. In conclusion, dietary supplementation with a combination of phytase and protease effectively enhances growth performance, feed efficiency, carcass traits, and meat quality in KUB chickens while modulating growth-related gene expression. Multienzyme inclusion represents a promising and cost-effective nutritional strategy for

Zoonotic hepeviruses, particularly hepatitis E virus (HEV, species Paslahepevirus balayani) represent a major yet underestimated public health challenge in Europe. Despite being the leading cause of acute viral hepatitis, surveillance, diagnostic practices and prevention strategies remain heterogeneous across EU/EEA countries, limiting comparability and hindering accurate burden estimates. Underdiagnosis is further compounded by extrahepatic manifestations and the growing impact of chronic HEV infection in immunocompromised patients. At the human-animal-environment interface, zoonotic HEV circulates widely in domestic pigs, wildlife and food products, while coordinated surveillance and control measures remain inconsistently implemented. The recent recognition of ratHEV (species Rocahepevirus ratti) as a cause of acute and chronic hepatitis in Europe further expands the spectrum of zoonotic hepevirus infections and underscores the need for integrated One Health approaches. To address these challenges, the One Health Zoonotic Hepevirus Network (ONWARD; COST Action CA24140) was launched in 2025 as a pan-European, multidisciplinary collaboration uniting experts across human, veterinary, food safety and environmental health sectors. ONWARD aims to harmonise diagnostic tools, strengthen clinical research, integrate multisectoral surveillance, promote capacity building and support evidence-based policy development. By fostering coordination with European stakeholders ONWARD provides a structured framework to strengthen preparedness, surveillance and response to zoonotic hepevirus threats across Europe.

INTRODUCTION: Taenia hydatigena is a widespread tapeworm. The predilection site of the adult form is the small intestine of its carnivore definitive hosts, and this site of the larval form, Cysticercus tenuicollis, is the abdominal visceral organs of its ungulate intermediate hosts. Cysticercal lesions are of food safety and economic importance, as they may condemn carcasses or internal organs of slaughtered animals and hunted game. The study aimed to evaluate the prevalence, intensity of infection and species composition of metacestodes from Polish roe deer and moose, and analyse the genetic diversity of the isolates. MATERIAL AND METHODS: Altogether, 167 roe deer (from the Mazowieckie and Łódzkie voivodeships) and 36 moose (from the Mazowieckie, Lubelskie and Podlaskie voivodeships) were studied. Metacestodes were collected post mortem and used for molecular investigations based on the partial cox1 (cytochrome c oxidase subunit 1) gene. RESULTS: The prevalence and the general intensity of infection were 9.6% and 1-6 cysts for roe deer, and 8.3% and 1-9 cysts for moose. Exclusively T. hydatigena infections were noted. Intraspecific genetic diversity of 1.42% was observed. The omentum and the mesentery were the most prevalent locations of metacestodes. CONCLUSION: Taenia hydatigena isolates from roe deer and moose varied genetically. Assuming national prevalence at the level observed in this study, the number of infected roe deer in Poland could exceed 18,000. Although T. hydatigena is not a zoonotic agent, its spread should be monitored and limited. Dogs should not be fed raw game meat in order to prevent parasitosis from spreading to farm animals. © 2026 Anna Maria Pyziel et al.

Avian pathology is the scientific study of diseases in birds, focusing on the structural, functional and molecular changes in tissues and organs caused by infections, toxins, nutritional deficiencies or others. It plays a critical role in maintaining poultry health, ensuring food security and supporting economic growth. The aim of this review is to highlight current trends, challenges and future directions in avian pathology, with a special emphasis on advancements in diagnostic approaches that enhance avian disease detection and management. However, the practical application of advanced technologies in avian pathology remains limited, particularly in Ethiopia. Recent diagnostic advancements, including immunohistochemistry, molecular techniques as well as digital pathology, have improved the detection, characterisation and management of poultry diseases. Future directions emphasise the use of artificial intelligence (AI) and machine learning for accurate diagnostics, real-time disease monitoring and outbreak prediction. Ethiopia has achieved significant progress in avian pathology, particularly through polymerase chain reaction and histopathology. Despite ongoing advancements, the poultry industry continues to face challenges, including emerging and re-emerging pathogens, limited access to diagnostic infrastructure, zoonotic risks and antimicrobial resistance. Therefore, strengthening biosecurity practices, promoting responsible antimicrobial use and expanding the use of molecular, digital pathology and AI-supported diagnostic tools remain essential strategies for protecting both poultry population and public health. To further enhance disease detection and control, diagnostic capacity and professional training in avian pathology should be strengthened in Ethiopia. © 2026 The Author(s).

To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant-based proteins is a promising route, but it also comes with challenges: Plant-based proteins often contain antinutritional factors and off-flavors, which can negatively impact consumer acceptance. Fermentation is broadly used to improve the quality of these products. However, how these unwanted molecules are synthesized and degraded is poorly understood, but this knowledge is essential for fermentation-based strategies to improve the sensory and nutritional value of plant-based products. This review provides a comprehensive overview of synthesis and degradation pathways of key antinutritional factors and off-flavor compounds in plant-based substrates, including aldehydes, furans, sulfur compounds, pyrazines, glycoalkaloids (GAs), pyrimidine glycosides, polyphenols, saponins, glucosinolates (GSLs), phytic acid (PA), oxalates, lectins, and protease and amylase inhibitors. With this we identified the research gaps in the field, which can be divided into three types: (i) degradation pathways that are unknown (furans, alkyl-methoxypyrazines, and dimethyl trisulfide), (ii) well-characterized pathways but typically not found in food-grade organisms (dimethyl sulfide, dimethyl disulfide, and isothiocyanates derived from GSLs), and (iii) pathways that are only described partially (GAs, saponins, polyphenols, PA, and pyrimidine glycosides). Other molecule classes, like aldehydes, alcohols, and oxalate, have well-characterized degradation pathways in food-grade organisms. Focusing future research on compounds with poorly understood degradation pathways will help to accelerate the development of more rationally designed cultures for producing healthy and sustainable plant-based foods. © 2026 The Author(s).

Lion's Mane mushroom (Hericium erinaceus) holds a significant place in traditional Chinese medicine (TCM), valued for centuries for benefiting various internal organs and overall well-being. It is also celebrated as a culinary delicacy in East Asia, prized for its fleshy, meat-like texture and mild, seafood-like flavor. High concentrations of glutamic and aspartic acids generate a pronounced umami taste, enhancing its culinary appeal and supporting its use as a natural flavor enhancer. Nutritionally, it provides dietary fiber, essential minerals, and high protein content, notably in the mycelial biomass (up to 42.5% dry weight), making it especially suitable as a protein source in meat alternative applications. The mushroom's therapeutic potential is rooted in its novel bioactive constituents. Hericenones (in fruiting bodies) and erinacines (in mycelia) are diterpenoids that stimulate nerve growth factor (NGF) synthesis, supporting neuronal function. Furthermore, immunomodulatory β-glucans, antioxidant phenolic compounds, and ergothioneine contribute to its overall health benefits. However, these functional properties are predominantly supported by in vitro and animal studies. Despite growing interest in its medicinal properties, integrated evaluations of the nutritional composition, bioactive profile, and technological potential of H. erinaceus for modern food applications remain limited. By leveraging both its sensory attributes and scientifically validated functional value, H. erinaceus can be incorporated into beverages, staple foods, and meat substitutes. This comprehensive review examines its dual role as a medicinal and culinary mushroom, to hopefully enhance understanding of the mushroom and inspire its future applications in food technology. © 2026 Institute of Food Technologists.

This study aims to systematically assess the comprehensive, dose-dependent effects of substituting soybean meal with cottonseed protein at various ratios on weaned piglets. In total, 28-day-old weaned piglets (Duroc × Landrace × Large White crossbred; n = 45) were selected and then randomly categorized into three groups: 100% soybean meal (CON), 50% soybean meal +50% cottonseed protein (CSP50), and 100% CSP (CSP100) groups. After a 7-day adaptation period, the experiment continued for an additional 28 days. The results showed no significant differences among groups in growth performance, organ indices, most carcass traits, or meat quality indicators. The CSP50 group showed significantly reduced levels of diamine oxidase (DAO) and D-lactate and increased complexity of the colonic microbial network, with improved abundance of beneficial bacterial genera such as g_Blautia and g_Eubacterium. The CSP100 group showed elevated intestinal permeability, a decreased villus height, a villus-to-crypt ratio, specific digestive enzymes, a reduced Firmicutes/Bacteroidetes (F/B) ratio and abundant inflammation-associated bacteria, including g_Streptococcus. Furthermore, correlation analysis suggested that specific gut microorganisms and metabolic pathways may be potentially related to average daily gain (ADG), average daily feed intake (ADFI), the feed conversion ratio (F/G), DAO, and D-lactic acid. These findings suggest that dietary inclusion of 50% cottonseed protein (CSP50) is associated with sustained growth performance and enhanced gut health in weaned piglets, concurrent with shifts in the composition and predicted function of the gut microbiota.

The gut microbiota (GM) is referred to as the central organ due to its dynamic and adaptable contact network with other organs through humoral, immunological, metabolic, endocrine, and neurological pathways. Recent studies have emphasized the concept of the "gut-organ axis", which shows that the effects of GM go beyond the gastrointestinal system (GIS) and encompass the reciprocal interactions between other organs. Communication along these axis occurs mainly through mediators such as short-chain fatty acids (SCFAs), microbial metabolites, neurotransmitters, cytokines, and hormonal signals. Therefore, imbalances in GM may surpass gut problems and be linked to diseases affecting the brain, liver, lungs, heart, mouth, skin, and many other organs. Understanding these reciprocal interactions can inform strategies for disease prevention and treatment. Emerging evidence suggests that interactions between the GM and other organ-specific metabolites it secretes are dynamic and influenced by various environmental and lifestyle factors, particularly diet. The gut and other organ microbiomes are maintained in balance with the help of nutritional supplements like probiotics, prebiotics, symbiotic, vitamins, omega-3 fatty acids, and dietary fiber. Consuming processed or red meat, high-fat, high-sugar, high-glycemic index foods, and excessive salt can upset this balance and raise the risk of systemic inflammation and disease. The purpose of this review is to examine the interactions between various organ-specific microbiomes in the human body, to elucidate the effects of these interactions on health, and to highlight how microbiome-targeted nutritional interventions can modulate these interactions, potentially affecting disease risk and overall metabolic homeostasis.

Functional seafoods derived from marine organisms, including fish, shellfish and algae, are gaining increasing attention due to their high content of bioactive compounds, such as omega-3 fatty acids, peptides, polysaccharides and antioxidants, which provide health benefits beyond basic nutrition. These marine-derived compounds exhibit a wide range of biological activities and have been investigated for their potential roles in the prevention and management of chronic diseases, including cardiovascular, neurodegenerative, cancer and gastrointestinal disorders. Their effects are largely mediated through anti-inflammatory, antioxidant and immunomodulatory mechanisms. Advances in biotechnology, including genetic engineering and improved extraction of bioactive compounds, have enhanced the nutritional quality and pharmacological relevance of functional seafoods. At the same time, sustainable aquaculture practices are being developed to reduce environmental impacts. Nevertheless, challenges such as regulatory inconsistencies, scalability issues and limited understanding of bioavailability and long-term effects still persist. These constraints should be considered when interpreting mechanistic and efficacy findings presented across different study designs and exposure conditions. Future perspectives highlight innovations in precision aquaculture, waste valorisation and traceability as key strategies to improve sustainability and strengthen consumer trust. This review summarizes current knowledge on functional seafoods, with emphasis on pharmacological mechanisms, clinical applications and the need for interdisciplinary research to optimize their health benefits and commercial potential.

The demand for fishmeal is increasing, but its supply is stagnating or even declining. There is an urgent need to find an eco-friendly and cost-effective alternative protein source. This study evaluated poultry by-product and insect meal as alternatives to fishmeal for the health performance and bioactivity of Nile tilapia. A Nile tilapia fry was divided into four groups with three replicates (No = 168). The first group was fed a basal diet containing 20% fishmeal (TFM). The second, third, and fourth groups received a basal diet where the fishmeal was substituted with poultry by-product meal (TPM), insect meal from Hermetia illucens (TIM), and a mixture of poultry by-product and insect meal (TMIX), respectively. The overall growth performance data indicated that TFM and TIM significantly achieved the highest growth rates and feed utilization (P < 0.05). The TIM diet significantly exhibited the highest total phenolic content, and both TIM and TFM showed superior antioxidant activity in fish muscle. There were no abnormal hematological or serum biochemical parameters observed in Nile tilapia fed insect meal and/or poultry by-product. The fish fillet samples from all groups were microbiologically safe for human consumption. Fish fed TIM displayed the lowest levels of TNF-α and the highest levels of IL-10 (P < 0.05). All the groups exhibited normal architecture of the internal organs. The significantly highest recorded absorption surface area was found in both TFM and TIM diets (P < 0.05). The NF-κB immunostaining showed no significant changes among experimental groups (P > 0.05). Based on this study, it can be suggested that the insect meal can be a sustainable and cost-effective substitute for conventional fishmeal in aquaculture feed formulations. © 2026. The Author(s).

Cellular senescence (CSEN) is caused by a variety of factors that trigger complex molecular pathways. These include telomere shortening, oncogene activation and replicative stress, as well as DNA damage caused by genotoxic anticancer drugs and endogenous and exogenous genotoxins. Here, we review the induction of CSEN by exogenous genotoxic insults resulting from food and environmental exposures. The available data show that genotoxins/carcinogens in tobacco smoke and smokeless tobacco, in the environment, in food, beverages and life-style products induce CNS. The exposures include N-nitroso compounds, polycyclic aromatic hydrocarbons, heterocyclic aromatic amines, acrylamide, heavy metals, fine dust, mycotoxins, phytotoxins, and phycotoxins. Also, heme in red meat contributes to CSEN as it catalyzes the formation of genotoxic species in the colon. Induction of CSEN by external genotoxins/carcinogens is bound on the DNA damage response pathway (DDR), which relies on activation of the ATM/ATR-CHK2/CHK1-p53-p21 axis and the p53-independent p16/p14 axis, eliciting cyclin-dependent kinase inhibition and permanent cell cycle arrest. Other factors that can be involved are DREAM, MAPK, cGAS/Sting, and NF-κB. The accumulation of non-repaired DNA damage triggering CSEN following external genotoxic exposures may contribute significantly to the amelioration of senescent cells and organ failure with age in humans. Senescent cells drive, via the senescence-associated secretory phenotype (SASP), inflammation that is involved in many diseases, including cancer. Although most of the studies were performed with in vitro cell systems, the consequences of CSEN induction by genotoxic nutritional components and environmental exposures seem to be underestimated. Since CSEN correlates with aging, it is reasonable to conclude that exogenous genotoxic pollutants contribute significantly to the aging process through CSEN induction. In light of these findings, it is deduced that reducing genotoxin exposures and using "rejuvenation" supplements (senotherapeutics) are reasonable strategies to counteract cellular senescence and the aging process.

Circadian rhythms are endogenous oscillations with a period of approximately 24 h. They enable organisms to anticipate and adapt to daily environmental changes, such as light and temperature. As the largest metabolic and motor organ in the body, skeletal muscle plays a decisive role in determining meat production efficiency in ruminants. Skeletal muscle development is largely governed by the proliferation and myogenic differentiation capacity of skeletal muscle satellite cells (SMSCs). More than 2,300 genes in skeletal muscle exhibit circadian oscillatory expression and are extensively involved in myogenesis, transcriptional regulation, and metabolic processes. The rhythmic expression of these genes is modulated by external factors including the photoperiod, feeding behavior, gut microbiota, and physical activity. Disruption of the endogenous circadian timing system can inhibit SMSC proliferation and myogenic differentiation, thereby impairing normal muscle development. Therefore, this review focuses on key management aspects of ruminant production-such as environmental control, nutritional regulation, and exercise management-and systematically elaborates on how these husbandry strategies may influence SMSC fate by modulating the circadian clock, along with the underlying molecular mechanisms. © 2026.

Energy and protein are important in chicken diets, with maize and soybeans traditionally serving as primary sources. Rising costs of maize and soybean meal have necessitated the search for sustainable alternatives, such as abundant cassava peel meal (CPM) and cassava leaf meal (CLM). CPM is rich in carbohydrates, minerals, and fibre, while CLM has high levels of amino acids, vitamins, and carotenoids. Both are deficient in sulphur-amino acids (cysteine and methionine) but rich in lysine, an amino acid often lacking in cereal grains. Low inclusion levels (≤ 12.5% CPM or ≤ 5% CLM) improve broiler growth performance compared to conventional diets without negative effects on carcass yield, meat quality, organ weights, or blood parameters, while lowering feed costs and increasing gross margins. In contrast, higher inclusion levels (> 20% CPM or > 15% CLM) impair growth and blood indices, due to high fibre content, residual hydrogen cyanide (HCN), and other antinutritional factors (ANFs) like condensed tannins and phytates. Enzyme supplementation alleviates these adverse impacts and enhances nutrient utilisation, though outcomes vary with processing method, plant part used, diet composition, and inclusion rate. The practical implication of these findings is that diets containing cassava by-products require careful formulation, especially to balance the limiting sulphur-containing amino acids. Future research should optimise processing techniques and enzyme combinations to support higher inclusion levels and maximising the potential of these abundant resources.

Allergic diseases are common chronic inflammatory conditions, which can affect multiple organs in severe cases, resulting in complex and varied clinical manifestations. Therefore, their management requires a more comprehensive and long-term strategy. A well-balanced diet is crucial in this context, as it regulates the immune system and improves atopic constitution, making it a key measure in preventing and controlling allergic diseases. Unlike observational studies prone to confounding and reverse causality, Mendelian randomization uses genetic variants as instrumental variables for stronger causal inference. This study employed the two-sample Mendelian randomization to investigate the potential causal relationships between 22 dietary factors and allergic diseases. The primary methods used were the weighted median method, MR-Egger regression, and inverse-variance weighted. To ensure the robustness and accuracy of the results, a series of sensitivity analyses, heterogeneity tests, and pleiotropy assessments were conducted. The study identified 7 dietary factors associated with allergic asthma, atopic dermatitis, and allergic rhinitis. The oily fish (OR: 0.666; 95% CI: 0.468-0.949; P = .024), dried fruit (OR: 0.463; 95% CI: 0.307-0.697; P = .00023), and cereal intake (OR: 0.595; 95% CI: 0.355-0.998; P = .049) was found to have a protective effect against asthma. The fresh fruit (OR: 0.592; 95% CI: 0.384-0.913; P = .018), tea (OR: 0.774; 95% CI: 0.603-0.995; P = .046), cereal (OR: 0.635; 95% CI: 0.430-0.939; P = .023), and processed meat intake (OR: 0.481; 95% CI: 0.294-0.787; P = .0036) were protective factors against atopic dermatitis. No significant causal relationships were observed between other dietary factors and these 3 diseases. These findings underscore the critical role of a balanced diet in the prevention and management of allergic diseases and highlight the potential of nutritional interventions in the future control and treatment of these conditions.

This study investigated the effects of dietary black cumin seed meal (BCSM) supplementation on growth performance, carcass traits, intestinal histomorphology, cecal microbiota, meat quality, and breast meat malondialdehyde (MDA) levels in Japanese quail. A total of 200 one-week-old quail were randomly allocated to four dietary treatments containing 0, 5, 10, or 20 g/kg BCSM for a 35-day experimental period, with five replicates per treatment. Dietary BCSM supplementation did not significantly affect body weight, body weight gain, feed intake, or conversion ratio (p > 0.05). However, carcass weight was significantly increased in birds fed 20 g/kg BCSM (p < 0.05), while carcass yield and relative internal organ weight remained unchanged. Intestinal histomorphology was markedly influenced by dietary treatments (p < 0.05), with improved villus height and villus height-to-crypt depth ratio in the jejunum and ileum of BCSM-fed birds. In addition, cecal microbiota analysis revealed a dose-dependent increase in Lactobacillus spp. (p < 0.05), whereas Escherichia coli counts were numerically reduced but not statistically affected (p > 0.05). Meat quality evaluation showed that BCSM supplementation significantly increased breast meat lightness (L*) and water-holding capacity and reduced post-slaughter pH values (p < 0.05). Lipid oxidation, as assessed by malondialdehyde (MDA) concentrations, was observed to be significantly lower in breast meat during refrigerated storage, suggesting a potential improvement in oxidative stability and a possible contribution to extended shelf life (p < 0.05). In conclusion, dietary inclusion of black cumin seed meal, particularly at 20 g/kg, positively modulated intestinal health, cecal microbiota composition, and meat oxidative stability without compromising growth performance. Owing to its high nutritional value and rich bioactive compound profile, BCSM can be considered a functional and sustainable feed ingredient for quail nutrition.

This investigation estimated the synergistic influences of garlic (Ga) and curcumin (Cu) supplementation on the growth performance, carcass features, immunity, antioxidant capacity, and gut histology of broiler chickens. A total of 300 Cobb 500 chicks were assigned to five dietary treatments: T1 (control) fed only basal diet; T2 fed basal diet supplemented with 0.25% Ga+0.25% Cu, T3: fed basal diet supplemented with 0.25% Ga+0.50% Cu, T4: fed basal diet supplemented with 0.50% Ga+0.25% Cu, and T5: fed basal diet supplemented with 0.50% Ga+0.50% Cu. The maximum inclusion level (0.50% Ga + 0.50% Cu, equivalent to 5 g/kg diet each) produced the greatest final body weight, weight gain and feed conversion ratio despite no change in feed intake according to the results which demonstrated a significant enhancement in growth performance with supplementation. While intramuscular fat dropped in the supplemented groups carcass yield and breast protein content increased significantly suggesting improved nutrient utilization and lean tissue accretion. Furthermore, birds given garlic and curcumin had improved mineral content in their breast meat and higher serum calcium and phosphorus concentrations. As evidenced by increased albumin levels and decreased serum AST and creatinine supplementation improved liver and kidney function indicators. IgG and IgM concentrations were highest in T5 birds, indicating an improvement in immune status. Superoxide dismutase activity was higher and malondialdehyde levels were lower, indicating a reduction in oxidative stress and an improvement in antioxidant defenses. Histologically supplemented birds-especially those in T5-showed longer healthier intestinal villi and well-preserved bursal follicles suggesting enhanced immune organ development and gut integrity. T5 achieved the greatest net revenue and efficiency according to economic evaluation. The results showed that curcumin and garlic work in concert to improve broiler performance, health and profitability. This is a natural substitute for antibiotics.

Capsaicinoids (CAPs) are widely investigated as natural alternatives to antibiotic growth promoters; however, most studies have examined capsaicin (CAP) alone, and the combined effects of CAP and dihydrocapsaicin (DHC) in encapsulated form remain largely unexplored in broilers. This study evaluated dietary encapsulated capsaicinoids (E-CAPs; 0.47% CAP and 0.22% DHC w/w) on growth performance, meat quality, serum biochemistry, antioxidant status, organ indices, intestinal morphology, and gut microbiota in Arbor Acres broilers. A total of 384 broilers were randomly assigned to a basal diet (CON) or diets supplemented with 150 mg/kg (LDC) or 450 mg/kg (HDC) E-CAPs. Compared with CON, HDC increased average daily gain and reduced the feed-to-gain ratio during the grower and overall periods (P < 0.05), whereas LDC showed limited effects. HDC also decreased serum alanine aminotransferase and total bile acid levels relative to CON (P < 0.05), without differences in other biochemical or antioxidant parameters or in organ indices and intestinal morphology, indicating good metabolic safety. Both LDC and HDC reduced crude fat content and thiobarbituric acid reactive substances levels in breast meat during refrigerated storage, without affecting meat color, compared with the CON group (P < 0.05). Relative to CON, HDC reduced the relative abundance of Actinomycetota and increased the relative abundances of Clostridium_innocuum, Alistipes, and Turicimonas (q < 0.05), accompanied by predicted enrichment of pathways related to bacterial secretion systems and antimicrobial resistance. Overall, supplementation with 450 mg E-CAPs/kg diet (≈3.1 mg total CAPs/kg) enhanced growth performance, improved meat quality, and beneficially modulated gut microbiota while maintaining metabolic and intestinal health, supporting the combined encapsulated CAP - DHC formulation as a safe and effective feed additive for broilers.

This study evaluated the effects of dietary distillers' dried grains with solubles (DDGS) levels on nutrient digestibility, meat quality, and intestinal health in meat ducks. In a 28-d feeding trial (Exp. 1), 400 Cherry Valley ducks (average body weight [BW] = 658.73 ± 3.79 g, age = 14 d old) were randomly assigned to five groups receiving 0 (CON), 5%, 10%, 15%, or 20% DDGS. Each treatment had eight replicates (cages) with ten ducks per replicate. A subsequent metabolism trial (Exp. 2) was conducted using the same diets. At 42 d of age, two ducks per replicate were randomly selected and fed diets supplemented with 0.5% titanium dioxide for digestibility determination. Results showed that 20% DDGS significantly reduced the digestibility of gross energy (GE; P = 0.010) and crude protein (CP; P = 0.026) compared to the CON group. As DDGS increased, CP digestibility decreased linearly (P = 0.001) and quadratically (P = 0.049). Serum triglyceride levels were significantly increased in the 20% DDGS group (P = 0.034). For meat quality, DDGS decreased breast muscle lightness (L∗45 min, P = 0.031) and increased yellowness (b∗45 min, P = 0.028). Shear force of breast muscle increased significantly in the 20% DDGS group (P = 0.009) and increased linearly with DDGS (P = 0.015). Histologically, DDGS supplementation decreased muscle fiber density (P = 0.005) and jejunal villus height (P = 0.001), but increased muscle fiber diameter (P = 0.027). Both muscle fiber diameter and density showed significant linear relationships with increasing DDGS levels (P = 0.003 and P < 0.001, respectively). Cecal butyric acid level decreased at 15% and 20% inclusion (P < 0.05), and valeric acid level decreased at 20% inclusion (P < 0.001). Notably, 10% DDGS increased cecal microbial diversity and the abundance of beneficial Prevotellaceae (P < 0.05). In summary, dietary inclusion of 5%-20% DDGS did not adversely affect growth performance, carcass traits, and organ indices in ducks. While higher levels impaired some meat quality traits, 10% DDGS was identified as the optimal level, improving intestinal microbiota without compromising overall production performance. These findings support the pa

Insects are commanding increasing attention as a sustainable and alternative nutritional source in animal feed. In this study, the safety and nutritional profile of the dampwood termite, Hodotermopsis sjostedti, were evaluated as a novel ingredient in chicken feed. Colonies were lab-reared, and individual termites were collected by carefully crushing the wood, freeze-drying, and grinding. The resulting termite meal contained 65.6% crude protein, 16.0% fat, and 5.2% ash, on a dry matter basis. No minerals were present at toxic concentrations. Two feeding experiments using Ross 308 female broilers were conducted to evaluate the effects of termite meal inclusion. In Experiment 1, 20 chickens (8-d-old) were assigned to four treatments consisting of a commercial diet plus: 5.0% fish meal, 4.5% fish meal + 0.5% termite meal, 2.5% fish meal + 2.5% termite meal, and 5.0% termite meal. In Experiment 2, 18 chickens (9-d-old) were assigned to three diets: control, control + 2.5% termite meal, and control + 2.5% fish meal. Body weight and feed intake were recorded daily, and samples were collected at 21 d of age. Growth performances, organ weights, and blood plasma profiles were generally comparable across treatments. Chickens receiving 5.0% termite meal had greater alanine aminotransferase values, suggesting a potential hepatic burden. No adverse effects on growth, meat, or organ weight were observed. In conclusion, H. sjostedti meal demonstrated strong potential as a novel dietary component for broiler chickens. However, further long-term studies with larger numbers of birds are necessary to ensure a safe and effective use in poultry diets. 2026 Japan Poultry Science Association.

OBJECTIVE: This study aimed to provide guidance for couples in dietary adjustments to optimize trace element concentrations for improved fertility and to offer a reference for formulating precise reproductive health policies. DESIGN: In this prospective cohort study, we analyzed 1,066 couples undergoing in vitro fertilization (IVF) from 2020 to 2023. Dietary intake was assessed using a Food Frequency Questionnaire, and 21 trace elements were measured. Multiple linear regression and factor analysis were used to evaluate associations. SETTING: Hefei City, Anhui Province, China. PARTICIPANTS: A total of 1,066 couples undergoing IVF treatment. RESULTS: In this study, we found significant associations between dietary intake and trace element concentrations in couples undergoing in vitro fertilization (IVF). Results showed that red meat consumption was inversely associated with Thallium (Tl) but positively correlated with Tin (Sn) and Cerium (Ce). Moderate intake of animal offal and processed meats showed significant associations with Aluminum (Al). Moderate sugar-sweetened beverage consumption was inversely linked to Tl levels. Furthermore, the moderate consumption of pickled and fried foods, as well as coffee, exhibited positive correlations with the trace elements Al and Manganese (Mn). Notably, as tea consumption increased, levels of Cobalt (Co), Gallium (Ga), and Strontium (Sr) also exhibited a significant rise. Even after False Discovery Rate (FDR) correction, the positive associations between Al levels and the moderate consumption of animal offal, pickled/fried foods, and coffee remained robust. Additionally, whole grain intake demonstrated a significant positive association with Sn, while tea consumption remained positively correlated with Rubidium (Rb). CONCLUSION: Our study emphasizes the significant impact of dietary intake on trace metal exposure in infertile couples. These insights can guide future research and help couples optimize trace elements through dietary modifications.

In recent years, edible by-products (including the liver) have gained growing popularity among consumers. That is why the study aimed to assess the energy value, chemical composition, and mineral content of broiler chicken livers after including wheat germ expeller (WGE) in the feed of the broilers. Liver samples were obtained from 32 Ross-308 chickens (8 individuals per treatment). The control group received a basal diet, whereas the remaining treatments (EX5, EX10, and EX15) were characterized by a partial substitution of ground wheat with 5%, 10%, and 15% WGE. The WGE inclusion did not influence liver weight or chemical composition. However, livers from the CT group showed a higher energy value (p ≤ 0.05) than the EX15 group. Sodium and calcium contents were higher in CT and EX5 livers than in EX10 and EX15. No differences were observed in micronutrient levels between groups. A 100 g portion of EX15 livers provided the highest NRV coverage for phosphorus, iron, zinc, and copper, while EX5 livers were richest in calcium and magnesium, and CT livers in manganese. Total Hazard Quotients for Fe, Zn, Cu, and Mn in chicken livers were below 1, suggesting no potential health risk to consumers. These findings indicate that livers, also from WGE-fed broilers, may serve as a valuable dietary source of minerals for people.

Low vitamin D status and intake are prevalent among the Australian population, including Aboriginal and Torres Strait Islander peoples. We hypothesised that some traditional foods could contain vitamin D, and measured vitamin D in foods from Nyoongar Country, Western Australia. Samples of kangaroo, emu, squid/calamari and lobster/crayfish were collected and prepared by Aboriginal people using traditional and contemporary methods. We measured vitamin D3, 25-hydroxyvitamin D3 (25(OH)D3), vitamin D2 and 25(OH)D2 using liquid chromatography-triple quadrupole mass spectrometry. Kangaroo meat and offal were largely devoid of vitamin D (no mean values >0.1 μg/100 g). Vitamin D3 was found in emu meat and calamari/squid (range 0.5-1.0 μg/100 g). No samples contained 25(OH)D3, vitamin D2 or 25(OH)D2 at mean values >0.1 μg/100 g. Modern food composition data can complement traditional knowledges in the promotion of traditional foods for healthy eating and social and emotional wellbeing among Aboriginal and Torres Strait Islander peoples.

BACKGROUND/OBJECTIVES: The rise in chronic metabolic diseases has led to the exploration of alternative diets. The carnivore diet, consisting exclusively of animal products, has gained attention, anecdotally, for imparting benefit for inflammatory conditions beyond that possible by other restrictive dietary approaches. The aim was to assess the micronutrient adequacy of four versions of the carnivore diet against national nutrient reference values (NRVs). METHODS: This study assessed the nutrient adequacy of the carnivore diet against national NRVs from the Australian National Health and Medical Research Council (NHMRC) and New Zealand Ministry of Health. Four meal plans for hypothetical average Australian adults were developed and analysed using Foodworks.online (Version 1, Xyris Pty Ltd., Brisbane, Australia, 2024), dietary software. Two female and two male plans were included; one set including dairy products and the other set including offal. RESULTS: The carnivore diet met several NRV thresholds for nutrients such as riboflavin, niacin, phosphorus, zinc, Vitamin B6, Vitamin B12, selenium, and Vitamin A, and exceeded the sodium threshold. However, it fell short in thiamin, magnesium, calcium, and Vitamin C, and in iron, folate, iodine and potassium in some cases. Fibre intake was significantly below recommended levels. CONCLUSION: The carnivore diet may offer benefits for managing certain chronic conditions. Whether the metabolic contexts from consuming such a diet facilitates a lower requirement of certain nutrients, or whether it poses risks of micronutrient inadequacies remains to be determined. Tailored nutritional guidance and supplementation strategies are recommended to ensure careful consideration of micronutrient intake to prevent deficiencies.

BACKGROUND: Camel meat tainted with heavy metals or trace elements may pose a health risk to consumers. Heavy metal contamination poses a severe danger due to both their toxicity and bioaccumulation in the food chain. AIM: To estimate the residual levels of heavy metals (Co, Cr, Mn, Se, and As) in muscle, liver, kidney, hair, and serum of three camel breeds (Magaheem, Maghateer, and Wadha) collected from Al-Omran abattoir, Al-Ahsa, Saudi Arabia. METHODS: A total of 225 tissue samples (muscles, liver, kidney, serum, and hair) were taken and analyzed using an Atomic Absorption Spectrophotometer. Health risk assessment was assessed using the guidelines set by the US Environmental Protection Agency. RESULTS: Camel breed significantly (p < 0.05) influences Co, Cr, Mn, and Se accumulation and distribution in organs and muscle; however, arsenic accumulation was not significantly affected (p < 0.05) by camel breeds. The highest values of Co, Cr, Se, and Mn in all examined samples were detected in the liver samples of Maghateer and Magaheem breeds. Furthermore, significant strong positive correlation between serum and liver cobalt, chromium, manganese, and arsenic. The estimated daily intake owing to camel meat consumption was less than the tolerated daily intake. CONCLUSION: Heavy metals were distributed among different breeds of camel. Trace elements (Pb and Cd) in meat and offal were below the international maximum permissible limit. The correlation between samples reflects the role of hair as a good tool for the identification of heavy metal pollution.

We previously demonstrated a beneficial effect of high-dose vitamin D in pregnancy on offspring bone and dental health. Here, we investigated the effect of maternal dietary patterns during pregnancy on the risk of bone fractures, bone mineralization and enamel defects until age 6 years in the offspring. Further, the influence of diet on the effect of high-dose vitamin D was analyzed in the COPSAC2010 mother-child cohort including 623 mother-child pairs. A weighted network analysis on FFQs revealed three specific maternal dietary patterns that associated (Bonferroni p < 0.05) with both offspring bone and dental health. The effect of prenatal high-dose (2800 IU/day) vs. standard-dose (400 IU/day) vitamin D on offspring bone mineral content (adjusted mean difference (aMD): 33.29 g, 95% CI: 14.48-52.09, p < 0.001), bone mineral density (aMD: 0.02 g/cm2 (0.01-0.04), p < 0.001), fracture risk (adjusted incidence rate ratio: 0.36 (0.16-0.84), p = 0.02), and enamel defects in primary (adjusted odds ratio (aOR): 0.13 (0.03-0.58), p < 0.01) and permanent molars (aOR: 0.25; (0.10-0.63), p < 0.01) was most pronounced when mothers had lower intake of fruit, vegetables, meat, eggs, sweets, whole grain, offal and fish. This study suggests that prenatal dietary patterns influence offspring bone and dental development, and should be considered in order to obtain the full benefits of vitamin D to enhance personalized supplementation strategy.

Deficiency of the necessary complex of micronutrients under abnormal nutrition structure creates a problem for the preservation of health and performance of the population. In this regard, it is very relevant to develop a science-based strategy for the consumption of traditional Yakut national food that have a high nutritional value and are able to satisfy the requirements of the human body in micronutrients. The purpose of the research was to investigate the content of selenium and zinc in the local foods which are most commonly consumed by the population of Yakutia. Material and methods. The objects of study were meat (7-9 cuts each) and offal (9-11 species each) of the Yakut cattle breed (2 bulls at the age of 2.5 years), of the Yakut horse foals (3 heads at the age of 6 months), northern domestic deer (3 heads), and whitefish (Coregonus muksun), Yakut crucian carp (Carassius carassius jacuticus), lake minnow [Phoxinus percnurus (Pallas)] (3 kg each). The trace elements, zinc and selenium, were determined by infrared spectroscopy. Results. The greatest amount of zinc in the meat of farm animals was noted in the meat of Yakut cattle (6.8±0.3 mg/100 g) and Yakut horse foals (6.7±0.2 mg/100 g), and the lowest - in the meat of domestic reindeer (1.5±0.1 mg/100 g). In terms of selenium content, the meat of domestic reindeer had the highest indicators (37.0±1.0 μg/100 g), and the meat of Yakut cattle had the lowest (19.0±0.8 μg/100g). The highest concentration of zinc and selenium was found in by-products of reindeer: zinc level in the heart and liver was 12.8 mg/100 g, in the small intestine and rennet - 19.0-20.4 mg/100 g, selenium level in the colon and rennet was 41.0-46.7 μg/100 g. The content of zinc and selenium in the fresh-water muksun belly (2.14±0.08 mg and 45.0±1.8 μg in 100 g) was 32.3-37.2% higher than in the fillet of muksun, and selenium level was 3 fold higher than in the Yakut carp and in the lake minnow. The consumption of 100-200 g of meat or by-products of Yakut cattle, Yakut horse foals, by-products of reindeer or Yakut crucian carp can fully cover the daily requirement of an adult in zinc. The consumption of 200 g of venison or muksun complet

It is unclear whether diet, and in particular certain foods or nutrients, are associated with lung cancer risk. We assessed associations of 92 dietary factors with lung cancer risk in 327 790 participants in the European Prospective Investigation into Cancer and Nutrition (EPIC). Cox regression yielded adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) per SD higher intake/day of each food/nutrient. Correction for multiple comparisons was performed using the false discovery rate and identified associations were evaluated in the Netherlands Cohort Study (NLCS). In EPIC, 2420 incident lung cancer cases were identified during a median of 15 years of follow-up. Higher intakes of fibre (HR per 1 SD higher intake/day = 0.91, 95% CI 0.87-0.96), fruit (HR = 0.91, 95% CI 0.86-0.96) and vitamin C (HR = 0.91, 95% CI 0.86-0.96) were associated with a lower risk of lung cancer, whereas offal (HR = 1.08, 95% CI 1.03-1.14), retinol (HR = 1.06, 95% CI 1.03-1.10) and beer/cider (HR = 1.04, 95% CI 1.02-1.07) intakes were positively associated with lung cancer risk. Associations did not differ by sex and there was less evidence for associations among never smokers. None of the six associations with overall lung cancer risk identified in EPIC were replicated in the NLCS (2861 cases), however in analyses of histological subtypes, inverse associations of fruit and vitamin C with squamous cell carcinoma were replicated in the NLCS. Overall, there is little evidence that intakes of specific foods and nutrients play a major role in primary lung cancer risk, but fruit and vitamin C intakes seem to be inversely associated with squamous cell lung cancer. © 2022 The Authors.

The natural gas industry bears a certain contamination risk to human and biota due to, among others, mercury, arsenic, and naturally occurring radioactive material content in gas. We tracked multiple stabile metal(loid)s and radionuclides within the natural gas treatment plant Molve, Croatia, ecosystem during the last decade through a comprehensive monitoring of soil, earthworms, moss, livestock (blood, milk, hair, urine, and feces from cows), and wildlife animals (brain, muscle, liver, and kidney of European hare and pheasant). The level of mercury and other stable metal(loid)s has shown temporal variation, but without an obvious trend. The found spatial differences in soil and earthworms were based on the differing soil characteristics of the sampled locations and exceeded the maximal allowable concentration of arsenic and zinc for agricultural soil. The status of essential copper, selenium, and zinc in cows, hares, and pheasants inclined towards deficiency. The measured stable metal(loid) levels in soil and animal samples were generally in the same range of values reported in earlier decades from the same area or non-polluted areas across Europe. The consumption of local cow and game products (e.g., milk, meat) can be considered safe for human health, although game offal is advised to be avoided as a food item due to the low risk of lead and cadmium's adverse effects. Although the activity concentrations of some radionuclides in moss were higher than reported for pristine areas, transfer from soil to moss was assessed as average (except for lead-210). Radiological risk to human and biota around the gas treatment plant Molve was estimated as negligible. © 2022. The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Quantification of the specific folate vitamers to estimate total folate in foods is not standardized. A collaborative study, including eight European laboratories, was conducted in order to determine the repeatability and reproducibility of the method for folate quantification in foods using the plant-origin γ-glutamyl hydrolase as part of the extraction procedure. The seven food samples analyzed represent the food groups; fruits, vegetables, dairy products, legumes, offal, fish, and fortified infant formula. The homogenization step was included, and six folate vitamers were analyzed using LC-MS/MS. Total folate content, expressed as folic acid equivalent, was 17-490 μg/100 g in all samples. Horwitz ratio values were within the acceptable range (0.60-1.94), except for fish. The results for fortified infant formula, a certified reference material (NIST 1869), confirmed the trueness of the method. The collaborative study is part of a standardization project within the Nordic Committee on Food Analysis (NMKL).

Food-derived bioactive peptides have generated an increasing interest in the field of health and well-being research. They can act either against the metabolic syndrome, participate in regulating the oxidation balance or act on the immune system. The aim of this study is to develop a workflow to generate bioactive peptides from three porcine offals namely, heart, liver, and lung and one muscle the Longissimus Dorsi, by combining in silico and in vitro approaches. Bioinformatics tools (e.i. BIOPEP and Uniprot) permitted to orientate the choice of enzymes for generating abundant bioactive peptides from the four studied porcine products. With papain and subtilisin, the main bioactivities potentially released were ACE inhibitors, DPP4 inhibitors and antioxidant peptides. An in vitro validation study using papain and subtilisin demonstrated high DPP4 inhibitors and antioxidant bioactivities for the generation of peptides. This work allowed: i) the identification of all proteins that composed porcine heart, liver, lung and LD muscle that could be useful for the scientific community, ii) the development of a workflow to select most abundant proteins in a product while considering abundance factors and iii) the potential of porcine meat and offals to generate DPP4 inhibitors and antioxidant peptides. However, there is still a need in developing new tools in order to face limitations of mass spectrometry for the identification of peptides with less than six amino acids. Such a work may contribute to the development of the circular economy and the innovative creation of value-added products from animal production.

The concentrations of heavy metals, such as chromium (Cr), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb), in different muscles and edible offal of consumed pork from the city of Nanjing and related health risks were evaluated. The results showed that the detected Hg concentrations from 6 of 80 samples exceeded the maximum allowable concentration (GB 2762-2017). Moreover, most of the edible offal, especially the kidneys, contained more heavy metals than the other parts, although the concentrations among the samples were significantly different (P < 0.05). In addition, the health risk evaluation revealed that the estimated daily intake of all the samples was far below the recommended limit, and all the target hazard quotients and total target hazard quotients were less than 1, which is considered safe for human health. Nevertheless, the Hg concentrations over the acceptable limit should receive sufficient attention, considering the long-term consumption of pork. PRACTICAL APPLICATION: Currently, no reports have been available on the heavy metal assessment of pork, though pork is widely consumed in many non-Muslim communities. In this study, the concentrations of heavy metals in different muscles and edible offal of consumed pork were determined and their related health risks were evaluated. This study will provide a significant reference to understand the quality and safety of pork in China or other similar developing countries. © 2020 Institute of Food Technologists®.

Livestock meat and offal contribute significantly to human nutrition as sources of high-quality protein and micronutrients. Livestock products are increasingly in demand, particularly in low- and middle-income settings where economies are growing and meat is increasingly seen as an affordable and desirable food item. Demand is also driving intensification of livestock keeping and processing. An unintended consequence of intensification is increased exposure to zoonotic agents, and a contemporary emerging problem is infection with Campylobacter and Salmonella spp. from livestock (avian and mammalian), which can lead to disease, malabsorption and undernutrition through acute and chronic diarrhoea. This can occur at the farm, in households or through the food chain. Direct infection occurs when handling livestock and through bacteria shed into the environment, on food preparation surfaces or around the house and surroundings. This manuscript critically reviews Campylobacter and Salmonella infections in animals, examines the factors affecting colonization and faecal shedding of bacteria of these two genera as well as risk factors for human acquisition of the infection from infected animals or environment and analyses priority areas for preventive actions with a focus on resource-poor settings. © 2019 Blackwell Verlag GmbH.

Optimal nutrition may play a beneficial role in maintaining a healthy brain. However, the relationship between nutrient intake and brain integrity is largely unknown. We investigated the association of specific nutrient dietary patterns with structural characteristics of the brain. Within the population-based Swedish National study on Aging and Care-Kungsholmen (SNAC-K), a cross-sectional study of 417 dementia-free participants aged ≥60 years who underwent structural magnetic resonance imaging (MRI) scans during 2001-2003, was carried-out. Data on dietary intake were collected using a food frequency questionnaire, from which intake of 21 nutrients was estimated. By principal component analysis, five nutrient patterns were extracted: (1) NP1 was characterized by fiber, vitamin C, E, β-carotene, and folate [Fiber&Antioxidants], (2) NP2 by eicosapentaenoic (EPA, 20:5 ω-3) and docosahexaenoic (DHA, 22:6 ω-3) polyunsaturated fatty acids (PUFAs), proteins, cholesterol, vitamin B3, B12, and D [long chain (LC) ω-3PUFAs&Proteins], (3) NP3 by α-linoleic (18:2 ω-6) and α-linolenic (18:3 ω-3) PUFAs, monounsaturated fatty acids (MUFAs), and vitamin E [MUFAs&ω-3,6PUFAs], (4) NP4 by saturated fatty acids (SFAs), trans fats, MUFAs, and cholesterol [SFAs&Trans fats], (5) NP5 by B-vitamins, retinol, and proteins [B-Vitamins&Retinol]. Nutrient patterns scores were tertiled with the lowest tertile as reference, and were related to total brain volume (TBV) and white matter hyperintensities volume (WMHV) using linear regression models adjusting for potential confounders. In the multi-adjusted model, compared to the lowest intake for each pattern, the highest intake of NP1 (β = 11.11, P = 0.009), NP2 (β = 7.47, P = 0.052), and NP3 (β = 10.54, P = 0.005) was associated with larger TBV whereas NP5 was related to smaller TBV (β = -12.82, P = 0.001). The highest intake of NP1 was associated with lower WMHV (β = -0.32, P = 0.049), whereas NP4 was associated with greater WMHV (β = 0.31, P = 0.036). In sum, our results suggest that the identified brain-health specific nutrient combinations characterized by higher intake of fruit, vegetables, legumes, olive and seed oils, fish, lean red meat,

This study aimed to evaluate the mean concentration of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), and lead (Pb) in the meat and offal of cow and sheep. Also, the estimated daily intake (EDI) and health risk of these metals were calculated. Analysis of metals was undertaken by the use of an inductively coupled plasma-optic emission spectroscopy (ICP-OES). All samples were contaminated with all metals. Principal component analysis (PCA) showed a clear differentiation of cow and sheep in both the kidney and liver samples. In the liver and kidney, level of Cd, Cu, and Pb were positively correlated. The highest target hazard quotients (THQs) were calculated for Pb. Cd level in cow kidney had the highest carcinogenic rate (CR). Although, hazard index (HI) was lower than one, consumption of muscle especially in children should be noticed in both national and international consumers due to higher level of HI.

Although not always labeled as such, flexitarianism is the default lifestyle for much of the world, whereby meals based on plant materials provide the bulk of people's calories. The rich nutrition of meat and animal products is often the lynchpin of these diets, even when only consumed occasionally. It provides forms and concentrations of essential proteins, lipids, and micronutrients that are otherwise scarce. However, the production of this meat is resource intensive. It requires large quantities of arable land and water, and typically has lower conversion efficiency of farm inputs to edible outputs compared with crops, poultry, aquaculture, dairy, and eggs. An additional complication is that the quantity of ancillary products produced during slaughterhouse operations is large and underutilized. Each year, approximately 190 million metric tons (MMT) of red meat, including pork, lamb, sheep, veal, beef, and goats are produced globally, half of which will be consumed by less than 25% of the population living in developed countries. With demand for meat expected to exceed 376 MMT by 2030, an increase in the adoption of plant-based diets presents an opportunity for the world to re-evaluate how meat can be sustainably produced, with greater emphasis on animal welfare, nutritional value, product safety, better utilization, and distribution channels. In this article we consider the role meat plays in the modern diet, its production and consumption, opportunities to improve utilization of the animal, the benefits of incorporating a diverse range of red meat into diets, and the strategies that the meat industry should consider in response to flexitarianism.

Living with pain is one of the distressing effects of food insecurity and malnutrition among millions of internally displaced persons (IDPs) worldwide. Vulnerability to emotional pain, metabolic imbalance, chronic illnesses and non-communicable diseases by IDPs are associated with stressed livelihood and restricted access to balanced diets in their camps. Tackling the complexity of issues related to internal displacement is challenging as 45% are globally trapped in protracted conditions. In this review, a diet-based intervention is proposed considering the potential benefits of nutrient synergy and analgesic constituents in organ meat. Providing an affordable, value added and well packaged nutrient dense diet is suggested to meet daily protein and micronutrient requirements from organ meat. Also, unlocking health-promoting bioactive substances and analgesics in restructured organ meat product is proposed as personalized dietary remedy to exert opioid bioactivity in food matrix. Exploiting the nutrient synergy of this animal by-product will not only improve the nutritional status or wellbeing but also raise the composite score of dietary diversity or food security index among IDPs by 2030.

This research aimed to investigate factors associated with vitamin D deficiency and to provide data about its prevalence in patients suffering from different psychiatric illnesses. The study had a cross-sectional design and it included 220 patients of both genders, aged from 19-81 y, with a wide range of mental disorders (F00-F89), and treated in routine ambulatory and hospital practice. The researchers collected data from three sources: medical records, a study questionnaire and biochemical analysis of patients' serum samples (concentration of vitamin D measured as 25(OH)D, calcium, phosphorus, magnesium, sodium and potassium). Data were analyzed using descriptive statistics, methods for hypothesis testing and binary logistic regression, at the p≤0.05 level. A total of 140 patients (64%) had a deficiency of vitamin D (<12 ng/mL), and 45 (20%) had inadequate vitamin D serum levels (12-20 ng/mL), while 35 (16%) had sufficient vitamin D serum concentrations (>20 ng/mL). Among variables related to demographics, life style habits, mental illness, comorbid disorders and drugs, two of them, female gender (odds ratio (OR)=2.5, 95% confidence interval (CI)=1.3-4.9, p=0.006) and using clozapine (OR=15.6, 95% CI 1.7-144.7, p=0.02), were significantly associated with vitamin D deficiency. Physical activity (OR= 0.4, 95% CI 0.2-0.9, p=0.02), exercising (OR=0.2, 95% CI <0.1-0.7, p=0.02) and offal in the diet (OR=0.5, 95% CI 0.3-0.9, p=0.03) significantly aggregated in the patients who had a 25(OH)D serum concentration above the deficiency cut-off level. Patients with mental disorders are at high risk for vitamin D deficiency, particularly females and clozapine users as well as those having no adequate physical activity or dietary habits.

Laser induced breakdown spectroscopy (LIBS) is an emerging technique in the field of food analysis which provides various advantages such as minimal sample preparation, chemical free, rapid detection, provision of spatial information and portability. In this study, LIBS was employed for quantitative analysis of copper content in minced beef samples spiked with beef liver over three independent batches. Copper content was determined with graphite furnace atomic absorption spectroscopy (GFAAS) in order to obtain reference values for modelling. Partial least square regression (PLSR) was performed to build a calibration and validation model. A calibration model with a high Rcv2 of 0.85 and a RMSECV of 43.5ppm was obtained, confirming a good fit for the model. The validation model showed a good prediction accuracy with a high Rp2 of 0.85 and RMSEP of 36.8ppm. Moreover, on a further study to evaluate the spatial capabilities, LIBS was able to successfully map copper content within a pellet, indicating the suitability of LIBS to provide spatial information and therefore potential use on heterogeneous samples. Overall, it can be concluded that LIBS combined with chemometrics demonstrates potential as a quality monitoring tool for the meat processing industry.

AIM: The main objectives of this study were for comparing the effect of batteries and deep litter rearing systems of domesticated Japanese quail, Coturnix coturnix japonica, on the concentration levels of cadmium, copper, lead, and zinc from the quail meat and offal in Ismailia, Egypt. MATERIALS AND METHODS: A total of 40 quail meat and their offal samples were randomly collected from two main quail rearing systems: Battery (Group I) and deep litter system (Group II) for determination of concentration levels of cadmium, copper, lead, and zinc. In addition, 80 water and feed samples were randomly collected from water and feeders of both systems in the Food Hygiene Laboratory, Faculty of Veterinary Medicine, Suez Canal University for heavy metals determination. RESULTS: The mean concentration levels of cadmium, copper, lead, and zinc in Group I were 0.010, 0.027, 1.137, and 0.516 ppm and for Group II were 0.093, 0.832, 0.601, and 1.651 ppm, respectively. The mean concentration levels of cadmium, copper, lead, and zinc in quail feed in Group I were 1.114, 1.606, 5.822, and 35.11 ppm and for Group II were 3.010, 2.576, 5.852, and 23.616 ppm, respectively. The mean concentration levels of cadmium, copper, lead, and zinc in quail meat for Group I were 0.058, 5.902, 10.244, and 290 ppm and for Group II were 0.086, 6.092, 0.136, and 1.280 ppm, respectively. The mean concentration levels of cadmium, copper, lead, and zinc for liver samples in Group I were 0.15, 8.32, 1.05, and 3.41 ppm and for Group II were 0.13, 8.88, 0.95, and 4.21 ppm, respectively. The mean concentration levels of cadmium, copper, lead, and zinc in kidney samples for the Group I were 0.24, 4.21, 1.96, and 4.03 ppm and for Group II were 0.20, 5.00, 1.56, and 3.78 ppm, respectively. Kidney had the highest concentration levels of heavy metals followed by liver then muscles. The highest concentration levels of copper were observed in liver samples. The order of the levels of these trace elements obtained from the four different quail organs is Ca > Pb > Zn > Cu. Lead and cadmium concentration levels in quail meat samples were exceeded the Egyptian standardization limits and suggesting a health threat fro
