Donkey milk has received increasing attention in recent years due to its unique nutritional composition and potential biological activities. This comprehensive review analyzed the main nutritional components of donkey milk, including proteins, lipids, carbohydrates, vitamins, and minerals, while also examining its significant biological activities such as antioxidant, antimicrobial, immunomodulatory, and anti-inflammatory properties. The protein profile of donkey milk is notable for its high proportion of whey proteins (55–65%), resembling human milk more closely than cow milk. Its relatively low-fat content (approximately 1.29%) with higher proportions of unsaturated fatty acids provides nutritional advantages for specific dietary needs. The carbohydrate content, primarily lactose, contributes to energy provision and calcium absorption. Donkey milk is also distinguished by its rich vitamin profile, particularly vitamin C (about 4.75 times higher than cow milk), and essential minerals including calcium, phosphorus, and zinc. The biological activities of donkey milk extend to various applications in infant nutrition, particularly for children with cow milk protein allergies, potential medical treatments for infections and inflammatory conditions, and cosmetic formulations. Despite these promising attributes, the donkey milk industry faces challenges including low milk yield, lack of standardized production methods, and quality control measures. The sustainable development of the donkey milk industry requires comprehensive approaches to resource protection, technological innovation, brand building, and supportive policies to realize its full potential in contributing to human health and economic development.

Due to its high digestibility, rich nutrient profile, and potential probiotic content, goat milk is an essential nutritional resource, particularly for individuals with cow milk allergies. This review summarises the current state of microbial diversity in goat milk, emphasising the implications for quality, safety, and probiotic potential. This systematic review adhered to PRISMA guidelines, conducting a comprehensive literature search across PubMed, ScienceDirect, and Google Scholar using keywords related to microbial profiling in goat milk. The inclusion criteria targeted English-language studies from 2000 to 2025 that utilised high-throughput or next-generation sequencing methods. Out of 126 articles screened, 84 met the eligibility criteria. The extracted data focused on microbial diversity, profiling techniques, and their respective strengths and limitations in evaluating probiotic potential and spoilage risks. The review addresses the challenges linked to microbial spoilage and the composition and functional roles of microbial communities in goat milk. With species such as Bacillus and Pseudomonas playing crucial roles in fermentation and spoilage, key findings emphasise the prevalence of microbial phyla, including Proteobacteria, Firmicutes, and Actinobacteria in goat milk. The review also explores the probiotic potential of the goat milk microbiota, highlighting the health benefits associated with strains such as Lactobacillus and Bifidobacterium. Significant discoveries underline the necessity for advanced multi-omics techniques to thoroughly define microbial ecosystems and the substantial gaps in breed-specific microbiota research. Important findings illustrate the need for enhanced multi-omics techniques, given the challenges of host RNA and protein interference, low microbial biomass, and limited goat-specific reference databases, for optimising probiotic development, spoilage prevention strategies, and integrating metagenomics, metabolomics, metaproteomics, and metatranscriptomics to improve milk quality and safety as some of the future research objectives. This study emphasises the importance of understanding goat milk microbiology to advance dairy science and enhance human health. Full article

Background. Cow’s milk allergy (CMA) is one of the most common food allergies in infancy, with prevalence estimates of 0.5–7.5% in high-income countries. Data from low- and middle-income regions remain limited, and the predominant immune mechanism (IgE or non-IgE mediated) may vary across populations. Objective. We aimed to determine the prevalence and clinical characteristics of CMA in infants from an urban, low-income Chilean population. Methods. A prospective cohort study was conducted at Padre Hurtado Hospital in Santiago, Chile. Healthy term newborns were recruited and followed for up to 12 months. Sociodemographic, perinatal data and parental atopy were recorded. Parents were contacted monthly to screen for CMA symptoms. Infants with ≥two symptoms underwent clinical evaluation, a 4-week cow’s milk protein exclusion diet, and an open oral food challenge (OFC). Diagnosis followed international consensus guidelines. Results. Of 552 enrolled infants (48% male), 27 were diagnosed with CMA, yielding a prevalence of 4.9% (95% CI 3.1–7.0%). All cases exhibited non-IgE-mediated symptoms, including vomiting, dermatitis, colic, and perianal erythema. CMA was diagnosed before 6 months of age in 74% of cases. At 12 months, 40% had developed oral tolerance. Sociodemographic and perinatal characteristics were similar between groups, but some self-reported parental atopic traits were more frequent in CMA cases. Conclusions. CMA prevalence in this Chilean cohort was comparable to that reported in high-income countries, with a predominance of non-IgE-mediated forms. These findings support the need for standardized diagnostic protocols, including OFC, in diverse populations. Future studies should explore long-term outcomes and risk factors in non-IgE-mediated CMA. Full article

Background: The pathophysiology of non-IgE-mediated cow’s milk allergy is mostly unknown. Previous studies suggested a mechanism mediated by T cells, but this was not confirmed in subsequent studies. The aim of this study was to investigate the immunological mechanisms, especially the role of regulatory T cells (Tregs), in the pathophysiology of allergic proctocolitis (FPIAP). Methods: A prospective observational study was conducted on infants with FPIAP and a control group of healthy infants with similar ages. The main variables were lymphocyte populations, included Tregs, which were extracted from peripheral blood and processed immediately by flow cytometry at two time points: in the acute phase (“T0”) and after clinical resolution (“Tres”). Results: A total of 32 patients with FPIAP and 10 healthy infants were enrolled. There was a higher T-CD4 memory cell count, increased numbers of regulatory B cells and a higher percentage of Tregs (p < 0.01) in patients with acute FPIAP in contrast to the healthy group. The levels of granulocytes (mainly eosinophils), dendritic cells (mDC2) and NK16+56- cells were also significantly higher in the FPIAP group. NK16+56- cells and the number of granulocytes appeared to be the best markers for distinguishing between the healthy and FPIAP infants based on the ROC curves. Conclusions: FPIAP does not appear to have an immune mechanism mediated by T cells, but it may be associated with innate immunity responses characterized by an increase in NK16+56- cells, eosinophils and dendritic cells. These cells could be evaluated in future studies as possible markers of non-IgE-mediated cow’s milk protein allergy. Full article

Background: The symptoms of cow’s milk allergy (CMA) can vary widely in severity and course, so diagnosis and treatment are still challenging. Objective: This study aims to establish the phenotype of severe CMA in children with the greatest improvement following the application of amino acid-based formula (AAF). Methods: This is a post hoc analysis of data from the multicenter, real-life study assessing the clinical effectiveness of a 5-week AAF intervention in 232 infants with severe CMA. A cluster analysis based on symptom severity at the 1st visit was performed. The differences in the severity scale of each symptom before and after the intervention were assessed and compared within and between clusters. The clustering results were validated in a separate cohort of infants with CMA (n = 157). Results: Three clusters were identified: cluster A (38.8% of patients) with moderate-to-severe gastrointestinal symptoms, cluster B (34.1%) with severe skin symptoms, and cluster C (25.9%) with combined moderate-to-severe gastrointestinal and severe skin symptoms. In the validation cohort, three clusters with the same pattern of symptoms were observed among children with moderate-to-severe CMA. The multivariate model of linear regression showed that severity score reductions after AAF treatment were significantly higher in cluster C than in clusters A and B, in children with a positive family history of allergy, and in children with growth retardation at baseline. Conclusion: Symptoms of severe CMA in children are grouped into three distinct phenotypes—gastrointestinal, skin, and combined gastrointestinal and skin. The most significant improvement after AAF implementation was obtained in patients with a combined phenotype. Full article

Cow’s milk allergy is one of the most prevalent food allergies in infancy. Exclusive breastfeeding is the recommended source of nutrition for the first six months of life, but some infants may develop cow’s milk allergy due to the transfer of milk proteins such as β-lactoglobulin through breast milk. There are still many uncertainties about cow’s milk allergy in breastfed babies. The purpose of this review is to summarize the latest findings mainly focused on immunological mechanisms and challenges in diagnosis. We pointed out which clinical signs in breastfed infants are associated with immediate IgE responses and which are linked to delayed non-IgE mechanisms or mixed IgE/non-IgE-mediated reactions. Since standard IgE tests are often useless in non-IgE cases, diagnosis typically involves dietary elimination and cow’s milk challenge. This study addresses the controversial topic of maternal elimination diets, assessing the nutritional risks to both mothers and infants in relation to their possible benefits. It has also been discussed whether the microbiota signature could be a potential factor in both tolerance development and the risk of cow’s milk allergy in early life. Overall, accurate diagnosis and personalized treatment plans are vital to prevent overdiagnosis and ensure proper growth while maintaining the practice of breastfeeding. Full article

Background: Cow’s milk is the most frequent cause of food allergies in children, with caseins and β-lactoglobulin being considered the main allergens. Concerningly, numerous international agencies have highlighted a growing risk of allergic reactions in milk-allergic individuals after the consumption of products labelled as “vegan”. Objectives: We describe the case of a 3.5-year-old boy with a history of a food allergy to milk who complained of anaphylactic clinical symptoms after eating a vegan Easter egg. The aim of this study was to confirm the cause of the clinical symptoms, searching for the possible presence of milk proteins in the vegan chocolate. Methods: An experimental approach based on electrophoretic (SDS-PAGE) and immunoenzymatic techniques (ELISA) was applied. Results: SDS-PAGE indicated the presence of milk proteins, which was confirmed and quantified via ELISA (3034 ± 115 mg/kg). Conclusions: The data obtained demonstrate that the severe clinical symptoms were due to the unexpected presence of milk proteins in a vegan product, underlining the critical need for rigorous allergen quality control throughout the food industry.

Cow milk allergy (CMA) is prevalently observed among infants and young children, exerting adverse effects on their growth and quality of life. Oral immune tolerance (OIT) is a more effective method for the prevention and treatment of CMA. The site of OIT is mainly in the gastrointestinal tract, so this article reviews the composition and structural characteristics of intestinal immune system, the molecular mechanisms of immune tolerance by regulatory T cells (Treg), dendritic cells, and gut microbiota. In addition, this paper summarizes the research progress of T cell epitope peptides of β-lactoglobulin and α-lactalbumin in whey protein hydrolysates. The mechanism of OIT induced by whey protein hydrolysate or whey protein combined with other anti-allergic components (phenolic compounds, probiotics, etc.) is overviewed to provide new ideas for the development of hypoallergenic infant formula.

Background/Objectives: Food hypersensitivity remains an understudied and overlooked subject globally. It is characterized by adverse reactions to dietary substances, potentially triggered by various mechanisms. Food allergy, a subset of food hypersensitivity, denotes an immune response to food proteins categorized into immunoglobulin IgE-mediated or non-IgE-mediated reactions. Conversely, food intolerance, another facet of food hypersensitivity, refers to non-immunological reactions, in which the human body cannot properly digest certain foods or components, leading to gastrointestinal discomfort and other non-immune-related symptoms. The main objective of this study was to determine and differentiate the differences, characteristics, and types of food hypersensitivity. Methods: This study involved a comprehensive review of key research from 1990 onward, including review articles, prospective studies, nested case–control studies, and meta-analyses. Results: Recognizing these differences is essential for healthcare professionals to ensure accurate diagnosis, effective management, and improved patient outcomes, while also aiding dietitians in providing optimal nutritional and dietary guidance. Conclusions: there are big differences between the main characteristics, such as symptoms, complications, and treatments between allergies, and food intolerances. Commonly reported trigger foods include cow milk, gluten, eggs, nuts, and seafood. Full article

Background. Cow’s Milk Protein Allergy (CMPA) is a prevalent pediatric food allergy affecting 2–5% of infants globally. CMPA presents significant clinical and economic challenges, requiring specialized diagnostic procedures, dietary management with hypoallergenic formulas, and multidisciplinary care. The financial burden on families and healthcare systems includes direct costs (e.g., diagnostic tests, medical consultations, and formula expenses), indirect costs (e.g., caregiver absenteeism and productivity loss), and intangible costs (e.g., psychological distress and impaired quality of life). Economic disparities further exacerbate these challenges, particularly in low-resource settings where access to specialized care is limited. Methods. A systematic review was conducted following PRISMA guidelines using PubMed, CINAHL, Scopus, and Cochrane databases to identify studies on the economic and psychosocial burden of CMPA. Studies published between 2010 and 2024 were analyzed. From an initial search of 11,565 articles, 802 duplicates were removed, leaving 10,763 articles for title and abstract screening. Twenty full-text articles meeting the inclusion criteria were included in the final analysis. Thematic categories focused on direct, indirect, and intangible costs, with findings synthesized to highlight global disparities and policy gaps. Results. CMPA management imposes substantial economic burdens, with hypoallergenic formulas alone accounting for up to 15% of household income in some regions. Indirect costs, including lost workdays and additional childcare expenses, further strain families. Intangible costs, such as heightened caregiver anxiety and reduced social participation, are significant yet frequently overlooked. Healthcare system disparities, particularly regarding insurance coverage for diagnostic tests and therapeutic formulas, contribute to financial inequities. The use of extensively hydrolyzed casein formulas with probiotics has demonstrated cost-effectiveness in promoting immune tolerance while reducing healthcare utilization. Conclusions. Addressing the economic impact of CMPA would benefit from standardized cost assessment frameworks and equitable access to cost-effective therapeutic options. Further analysis of reimbursement policies across diverse healthcare systems may provide insights into optimizing support for essential treatments. Integrating clinical and economic strategies can alleviate the burden on affected families and optimize healthcare resource allocation. Future research should prioritize longitudinal analyses and cross-regional comparisons to guide sustainable and equitable management strategies. Full article

Background/Objectives: Infant functional disorders, including colic, irritability, and sleep disturbances, often overlap with symptoms of cow’s milk protein allergy (CMPA). While extensively hydrolyzed formulas are commonly used to address these issues, the short-term efficacy of amino acid formulas (AAF) for managing colic remains understudied. This secondary analysis of a previously published prospective cohort, the largest of its kind in the United States, evaluated the short-term impact of AAF in improving colic and associated symptoms in infants under six months of age with suspected CMPA. Methods: This real-world prospective cohort study analyzed data from 138 infants with suspected CMPA initiated on AAF at Visit 1. After excluding 34 infants due to incomplete data or treatment changes, 104 infants were included in the final analysis. Symptom severity and resolution were assessed through outcomes across two visits, with care provided by general pediatricians (82%) and pediatric gastroenterologists (18%). Results: At baseline, the most common symptoms were colic (n = 83), gassiness (n = 72), fussiness (n = 66), and sleep disturbances (n = 58). By the next follow-up visit (Visit 2), parents reported symptom improvements in colic (94%), gassiness (81%), fussiness (83%), and sleep disturbances (86%). Complete symptom resolution was observed in 73% of infants with colic, 68% with gassiness, 65% with fussiness, and 81% with sleep difficulties. By Visit 2, no infants had severe symptoms, with only mild residual symptoms reported. Conclusions: AAF was associated with significant short-term improvements in colic and related symptoms in infants with suspected CMPA. These preliminary findings highlight AAF as a promising dietary intervention during early infancy. Larger controlled studies are necessary to confirm these results and explore long-term outcomes.

Objectives: Early environmental factors have a significant impact on the development of atopic conditions in children. Breastfeeding has been highlighted for its role in enhancing both immune support and cognitive development. Early allergic conditions and maternal behaviors are linked to cognitive and neurodevelopmental challenges. Our study aims to compare children from atopic families focusing on early nutrition and the neuropsychological development of children, especially in the presence of an allergic predisposition. Materials and methods: The study included 120 children with a family history of allergies (55% boys). Children were divided into group A, children breastfed for at least two months, and group B, children breastfed for less than two months or fed with formula. The study measurements and outcomes included demographic and social data, medical data, the smoking status of the parents, breastfeeding and early feeding practices, and anthropometric measurements. The assessment of the neurological development was carried out with a validated Developmental Profile-3 questionnaire. Diagnosis of allergic conditions was carried out with the SCORAD (SCORing Atopic Dermatitis) questionnaire for assessing atopic dermatitis; the CoMiSS (Cow’s Milk-Related Allergy Symptom Score) questionnaire for potential cow’s milk protein allergy and Prick testing and elimination-provocation protocol were used to confirm allergic status in children with atopic conditions. Data were analyzed using Jamovi 2.2.2 software, with statistical significance set at p ≤ 0.05. Results: The age of the examined children was 13 ÷ 31 months, the age of the mothers was 21 ÷ 42 years, and that of the fathers was 22 ÷ 44 years. Educational levels among mothers were 68.35% (n = 54) with higher education in group A and 61.5% (n = 24) in group B, compared to fathers with rates of higher education of, respectively, 54.3% (n = 44) and 38.5% (n = 15). The average gestational age of the children was 38.8 ± 1.08 weeks, and the relative share of cesarean delivery—50.8% (n = 61)—was slightly higher than vaginal delivery. Anthropometric results (HAZ, WAZ, BMIAZ) did not show a statistically significant influence of the type of feeding (breastfeeding, standard formula, or hydrolyzed formula) on growth during the first two months after birth (p > 0.05). During the study period, a significant number of the children developed allergic conditions, which were more common in children from group A—43.2% (n = 35)—compared to group B—38.5% (n = 15). In the families included in the study, mothers smoked more often (53.3%; n = 64) than fathers (43.3%; n = 52), and 13.3% (n = 16) of the women smoked during pregnancy. Children’s neuropsychological development, assessed with the DP-3 questionnaire, according to the duration of breastfeeding, does not show statistically significant differences for the five functional areas (“Physical development”, “Adaptive behavior”, “Social-emotional” Development”, “Cognitive development “, and “Communication”) or the overall development of children from both groups. The neuropsychological development (DP-3) of the group A children showed correlations with the presence of atopic dermatitis, parents’ age, father’s level of education, mother’s smoking during pregnancy, number of cigarettes smoked by the mother per day, and cesarean delivery. Maternal smoking (number of cigarettes per day) had significant negative correlations with all areas of children’s neuropsychological development, which were most pronounced with physical (rho = −0.352; p = 0.001) and overall development (rho = −0.329; p= 0.003). Cesarean delivery moderately correlated with physical development (rho = 0.292; p = 0.008) and adaptive behavior (rho = −0.294; p = 0.008). In group B, neuropsychological development (DP-3) correlates most clearly with allergic conditions (allergy at two years of age and atopic dermatitis), as well as with maternal smoking during pregnancy, with a strong negative correlation with physical development (rho = −0.510; p = 0.001). Conclusions: Our study reinforces the link between early feeding practices, neuropsychological development, and allergic conditions, emphasizing the lasting effects they have on children’s neurological health. However, limitations such as the relatively small sample size and reliance on parental reporting may affect the generalizability of the findings. Future studies with larger cohorts and objective biomarkers for allergic conditions are needed to further validate these results. Full article

Eosinophilic esophagitis is a chronic, antigen-driven, immune-mediated disease characterized by esophageal dysfunction and significant eosinophilic infiltration. Its rising incidence and prevalence over recent decades reflect both increased clinical awareness and the influence of environmental factors such as dietary patterns and allergen exposure. Among food allergens, cow’s milk proteins are the most commonly implicated triggers, contributing to esophageal inflammation through complex immunological pathways involving both IgE-mediated and non-IgE-mediated mechanisms. Dietary elimination of cow’s milk has been shown to induce histologic remission in over 60% of pediatric patients, underscoring its pivotal role in eosinophilic esophagitis management. Despite these promising results, challenges persist, including variability in individual responses, the burden of adherence to restrictive diets, and gaps in understanding the molecular mechanisms driving cow’s milk-induced esophageal inflammation. This review examines the complex relationship between eosinophilic esophagitis and cow’s milk, focusing on its role in disease pathogenesis and management, offering insights into its therapeutic implications. Understanding the interplay between eosinophilic esophagitis and dietary allergens, particularly cow’s milk, may inform the development of targeted interventions and improve clinical outcomes for affected patients.

Background: Hydrolysed rice formula (HRF) is tolerated by >90% of children with cow’s milk protein allergy (CMPA). However, concerns have been raised about potential suboptimal growth in infants fed HRF compared to those fed an extensively hydrolysed milk protein formula (eHF). Aims: To compare growth, safety and tolerance acquisition in infants with CMPA when fed HRF versus eHF. Methods: A multicentre prospective, randomised, double-blind, placebo-controlled food challenge trial was conducted with infants with CMPA. The infants received either HRF or eHF over a 12-month follow-up period. The primary outcome measure was the change from baseline over the study period in weight-for-length expressed as a Z-score. The secondary outcomes were other anthropometric measurements, tolerability and adverse events (AEs). Results: In total, 105 children were enrolled. The weight-for-length measurements were −0.01 (HRF) and −0.29 (eHF) at baseline and 0.29 and 0.05, respectively, at the last visit, with no significant between-group difference (p = 0.28; mixed-effects model). The Z-scores for other anthropometric variables indicated normal growth, with no significant between-group differences. In total, 29 potentially product-related AEs were reported (12 in the HRF group and 17 in the eHF group). A trend was observed toward a faster acquisition of tolerance in the HRF group (median age: 20.4 months) compared to the eHF group (16.3 months), but this was not statistically significant (p = 0.18). Conclusions: HRF demonstrated appropriate growth, acquisition of tolerance and a good safety profile in infants with CMPA, with no significant differences versus eHF. HRF could be considered as an appropriate option in the management of CMPA. Full article

Background/Objectives: Food protein-induced allergic proctocolitis (FPIAP) is a non-IgE-mediated food allergy, usually presenting as bloody stools in breastfed, well-appearing, and regularly growing infants. The aim of our study was to describe the clinical features of Italian infants affected by FPIAP and their management and natural history in a real-life setting. Methods: A retrospective, observational study was performed at two tertiary pediatric hospitals (Florence and Trieste), including FPIAP-diagnosed infants between 2012 and 2022. Results: Most of the 100 enrolled patients were breastfed (68.0%), and the majority of those who underwent diagnostic tests (n = 51) showed normal hemoglobin and total IgE levels. A maternal elimination diet was performed in 69.0%, mostly for milk only, but 40.6% underwent multiple elimination diets. The remission rate was high both in breastfed infants (76.8%) and in those who received extensively hydrolyzed formula (81.8%). Nine subjects were left on a free diet, but six were lost at follow-up. The median time of complete remission was 30 days (IQR 14–60). Culprit food reintroduction was tolerated at a median age of 8 months (IQR 6–11), in ladder modality (for hen’s egg and cow’s milk) in 61.7%. Nine patients relapsed (14.3%) upon reintroduction with no associated variables identified at the regression analysis. The relapse rate was slightly higher when trigger food reintroduction was attempted > 12 months (16.7%) versus <12 months (13.0%). Conclusions: In our population, FPIAP had, as expected, a benign evolution. The early reintroduction of the suspect food in a gradual manner for cow’s milk and hen’s egg leads to good tolerance within the first year in most patients, avoiding unnecessary elimination diets.
