RESUMEN
The objective of the present study is to assess the rates of acquired tolerance to cow's milk (CM) after 36 months in subjects who consumed amino acid-based formula with synbiotics (AAF-S) or amino acid-based formula without synbiotics (AAF) during a 1-year intervention period in early life as part of the PRESTO study (Netherlands Trial Register number NTR3725). Differences in CM tolerance development between groups were analysed using a logistic regression model. Results show that the proportion of subjects (mean [±SD] age, 3.8 ± 0.27 years) who developed CM tolerance after 36 months was similar in the group receiving AAF-S (47/60 [78%]) and in the group receiving AAF (49/66 [74%]) (p = 0.253), that is, figures comparable to natural outgrowth of CM allergy. Our data suggest that the consumption of AAF and absence of exposure to CM peptides do not slow down CM tolerance acquisition.

BACKGROUND: In addition to the elimination diet, dietary composition may influence disease severity in patients with eosinophilic esophagitis (EoE) through modulation of the immune response. AIM: To explore the immunomodulatory role of nutrition before and during elimination diet in adult EoE patients. METHODS: Nutritional intake was assessed in 39 Dutch adult EoE patients participating in the Supplemental Elemental Trial (Dutch trial registry NL6014, NTR6778) using 3-day food diaries. In this randomized controlled trial, diagnosed patients received either a four-food elimination diet alone (FFED) or FFED with addition of an amino acid-based formula for 6 weeks. Multiple linear regression analyses were performed to assess associations between the intake of nutrients and food groups per 1000 kCal and peak eosinophil count/high power field (PEC), both at baseline and after 6 weeks. RESULTS: At baseline, we found a statistically significant negative (thus favorable) relationship between the intake of protein, total fat, phosphorus, zinc, vitamin B12, folate, and milk products and PEC (p < .05), while calcium (p = .058) and full-fat cheese/curd (p = .056) were borderline (favorably) significant. In contrast, total carbohydrates, prepacked fruit juice, and white bread were significantly positively (unfavorable) related to PEC (p < .05), while ultra-processed meals (p = .059) were borderline (unfavorably) significant. After dietary intervention, coffee/tea were significantly negatively (favorably) related to PEC, hummus/legumes were significantly positively (unfavorably) related with PEC, while peanuts were borderline significantly positively related (p = .058). CONCLUSION: Dietary composition may be related to inflammation in adult EoE patients. High-quality and anti-inflammatory diets may be a promising adjuvant therapy in the dietary management of EoE.

The African region encompasses the highest undernutrition burden with the highest neonatal and infant mortality rates globally. Under these circumstances, breastfeeding is one of the most effective ways to ensure child health and development. However, evidence on human milk (HM) composition from African women is scarce. This is of special concern, as we have no reference data from HM composition in the context of food insecurity in Africa. Furthermore, data on the evolution of HM across lactational stages in this setting lack as well. In the MITICA study, we conducted a cohort study among 48 Central-African women and their 50 infants to analyze the emergence of gut dysbiosis in infants and describe the mother-infant transmission of microbiota between birth and 6 months of age. In this context, we assessed nutritional components in HM of 48 lactating women in Central Africa through five sampling times from week 1 after birth until week 25. Unexpectedly, HM-type III (Secretor + and Lewis genes -) was predominant in HM from Central African women, and some nutrients differed significantly among HM-types. While lactose concentration increased across lactation periods, fatty acid concentration did not vary significantly. The overall median level of 16 detected individual human milk oligosaccharides (HMOs; core structures as well as fucosylated and sialylated ones) decreased from 7.3 g/l at week 1 to 3.5 g/l at week 25. The median levels of total amino acids in HM dropped from 12.8 mg/ml at week 1 to 7.4 mg/ml at week 25. In contrast, specific free amino acids increased between months 1 and 3 of lactation, e.g., free glutamic acid, glutamine, aspartic acid, and serine. In conclusion, HM-type distribution and certain nutrients differed from Western mother HM.
RESUMEN
Although the World Health Organization (WHO) and UNICEF recommend that infants should be exclusively breastfed for the first 6 months of life, evidence is scarce on how the mother's undernourishment status at delivery and maternal dietary factors influence human milk (HM) composition during the first 6 months of life in regions with high food insecurity. The maternal undernourishment status at delivery, maternal diet, and HM nutrients were assessed among 46 women and their 48 vaginally born infants in Bangui at 1, 4, 11, 18, and 25 weeks after birth through 24-h recalls and food consumption questionnaires from December 2017 to June 2019 in the context of the "Mother-to-Infant TransmIssion of microbiota in Central-Africa" (MITICA) study. High food insecurity indexes during the follow-up were significantly associated with them having lower levels of many of the human milk oligosaccharides (HMOs) that were measured and with lower levels of retinol (aß-coef = −0.2, p value = 0.04), fatty acids (aß-coef = −7.2, p value = 0.03), and amino acids (aß-coef = −2121.0, p value < 0.001). On the contrary, women from food-insecure households displayed significantly higher levels of lactose in their HM (aß-coef = 3.3, p value = 0.02). In parallel, the consumption of meat, poultry, and fish was associated with higher HM levels of many of the HMOs that were measured, total amino acids (aß-coef = 5484.4, p value < 0.001), and with lower HM levels of lactose (aß-coef = −15.6, p value = 0.01). Food insecurity and maternal diet had a meaningful effect on HM composition with a possible impact being an infant undernourishment risk. Our results plead for consistent actions on food security as an effective manner to influence the nutritional content of HM and thereby, potentially improve infant survival and healthy growth.

Background and Aims: The content of fatty acids (FA) in human milk may be influenced by maternal nutrition. We evaluated the role of a Mediterranean diet in influencing the content of FA in human milk among 282 breastfeeding mothers participating in the MEDIDIET study. Materials and Methods: Mediterranean Diet Score (MDS), a composite index, was used to evaluate adherence to the Mediterranean diet. It includes 9 components (i.e., vegetables, fruit, cereals, legumes, monounsaturated to saturated FA ratio - MUFA/SFA, fish, dairy products, meat, and alcohol) and therefore potentially ranges from 0 (no adherence) to 9 (complete adherence) points. None of the mothers obtained the highest score due to the low alcohol consumption in the study population. Mothers were categorized in approximate tertiles of adherence: 0-3 (34.4%), 4 (26.2%), and 5-8 points (39.4%). The mean content of FA across categories of MDS was compared using ANOVA and test for trend. Results: A high adherence of breastfeeding mothers to the Mediterranean diet was associated with lower content of SFA in human milk (42.58 ± 4.36 for MDS = 0-3, 42.58 ± 4.89 for MDS = 4, and 40.92 ± 5.22% of fats for MDS = 5-8 points; p ANOVA and p for trend = 0.02). Conversely, a high adherence was associated with higher content of MUFA in human milk (43.27 ± 4.27 for MDS = 0-3, 43.27 ± 4.47 for MDS = 4, and 45.24 ± 5.22% of fats for MDS = 5-8 points; p ANOVA and p for trend < 0.01), ω-3 FA (1.07 ± 0.25 for MDS = 0-3, 1.22 ± 0.49 for MDS = 4, and 1.31 ± 0.51% of fats for MDS = 5-8 points; p ANOVA and p for trend < 0.01), and the major types of ω-3 FA (i.e., α-linolenic acid - ALA, eicosapentaenoic acid - EPA, docosahexaenoic acid - DHA, docosapentaenoic acid - DPA). These associations were mainly driven by the adherence to the vegetables, MUFA/SFA, fish, and dairy products components of the Mediterranean diet. Conclusion: A high adherence to the Mediterranean diet was associated with human milk showing a lower content of SFA and higher content of MUFA and ω-3 FA, including DHA. The Mediterranean diet may contribute in human milk production with higher content of specific FA which is directly involved in infant's neural and visual development, as reported by previous studies.
RESUMEN
BACKGROUND: Elimination of key foods restricts dietary options in eosinophilic esophagitis (EoE) patients. Addition of amino acid-based formula (AAF) to an elimination diet might facilitate adherence and, therefore, enhance efficacy of dietary management. AIM: To evaluate whether addition of AAF to a four-food elimination diet (FFED) is more effective than FFED alone in decreasing eosinophilia, endoscopic signs, and clinical outcomes. METHODS: This randomized controlled trial enrolled 41 adult patients with active EoE (≥15 eosinophils (eos) per high power field (hpf)) at baseline biopsy. Subjects were randomized (1:1 ratio) to groups given a FFED or FFED with addition of AAF providing 30% of their daily energy needs (FFED + AAF). Histological disease activity, endoscopic signs, symptoms, and disease-related quality of life (EoEQoL) were measured at baseline and after 6 weeks of intervention. RESULTS: Patients (60% male, age 34.5 (interquartile range (IQR) 29-42.8 years)) were randomized to FFED (n = 20) or FFED + AAF (n = 21); 40 participants completed the diet. Complete histological remission (<15 eos/hpf) was achieved in 48% of FFED + AAF subjects (n = 21) vs. 25% of FFED subjects (n = 20), respectively (p = 0.204). Peak eosinophil counts (PEC) decreased significantly in both groups between baseline and week 6, but the change in PEC between groups was not different (p = 0.130). A significant but similar endoscopic and symptomatic reduction was observed in both groups (all; p<0.05). Total EoEQoL scores significantly improved in the FFED + AAF group between baseline and week 6 (p = 0.007), and not in the FFED group. CONCLUSION: The addition of AAF to a FFED did not lead to a larger decrease in PEC between baseline and 6 weeks, but may result in a significant improvement of QoL in adult EoE patients NL6014 (NTR6778).

INTRODUCTION: The present study aimed to explore the relationship between the dietary intake and the human milk (HM) fatty acid (FA) profile of Chinese lactating women. METHODS: HM samples and food records were obtained from 122 Chinese women over 5 visits between 0 and 51 days postpartum. Adjusted multiple regression was performed to explore associations between maternal dietary intakes of energy, macronutrients, FAs and foods, and the HM FA profile. Analyses were performed separately for colostrum and mature milk. RESULTS: Dietary intakes of total polyunsaturated FAs (PUFAs), eicosapentaenoic acid (EPA), and docosahexaenoic acid were positively associated with the HM contents of PUFAs, omega-6 (n-6) PUFAs, and linoleic acid (LA), and the intakes of n-3 PUFAs and α-linolenic acid (ALA) were negatively associated with saturated FA levels in HM. Associations were stronger for mature milk. Intakes of milk/dairy, meat/poultry, and eggs were negatively associated with n-6 PUFAs, LA, and EPA in mature milk, whereas the opposite was seen for fish/shrimp. Positive associations were also found between fish/shrimp and total and n-3 PUFAs in mature milk. CONCLUSION: The HM FA profile of Chinese women is associated with their diet, and in particular with their FA intake. Tailored nutritional advice based on HM FA composition may optimize HM FA profile and thereby contribute to healthy infant development.

Among the human milk oligosaccharides (HMOS), the galactosyllactoses (GLs) are only limitedly studied. This study aims to describe the presence and relative levels of HMOS, including GLs, in human milk (HM) according to maternal Secretor and Lewis (SeLe) phenotype and lactation stage. Relative levels of 19 HMOS were measured in 715 HM samples collected in the first 4 months postpartum from 371 donors participating in the PreventCD study. From a subset of 24 Dutch women (171 HM samples), samples were collected monthly up to 12 months postpartum and were additionally analyzed for relative and absolute levels of ß6'-GL, ß3'-GL and α3'-GL. Maternal SeLe phenotype or HM group was assigned based on the presence of specific fucosylated HMOS. Most HMOS, including ß6'- and ß3'-GL, were present in the vast majority (≥75%) of HM samples, whereas others (e.g., LNDFH II, 2'-F-LNH and α3'-GL) only occurred in a low number (<25%) of samples. Clear differences were observed between the presence and relative levels of the HMOS according to the maternal phenotype and lactation stage. Absolute concentrations of ß6'-GL and ß3'-GL were higher in HM group IV samples compared to samples of the other three HM groups. ß3'-GL was also higher in HM group II samples compared to HM group I samples. ß3'-GL and ß6'-GL were stable over lactation stages. In conclusion, presence and levels of HMOS vary according to HM group and lactation stage. Not all HMOS behave similarly: some HMOS depend strongly on maternal phenotype and/or lactation stage, whereas others do not. ß3'-GL and ß6'-GL were present in low concentrations in over 75% of the analyzed HM samples and showed differences between HM groups, but not between the lactation stages.

BACKGROUND: Lactation is a demanding period for women, and a good nutrition is crucial for optimal health of mothers and infants. OBJECTIVES: To provide new data and summarize the overall evidence on maternal nutrient intakes during lactation in developed countries, we present a systematic review (SR) of the literature and concurrently original results of the Italian MEDIDIET study. We compared nutrient intakes with dietary reference values (DRVs) proposed by the European Food Safety Authority. METHODS: Studies were identified searching PubMed/Embase databases up to February 2020. Observational studies reporting at least energy and macronutrient intakes of healthy breastfeeding mothers who followed non-restricted and non-specific diets were included. Studies on populations with severe nutritional deficiencies were excluded. The MEDIDIET study enrolled 300 healthy breastfeeding mothers at 6 ± 1 wk postpartum. Usual diet was concomitantly evaluated through a validated and reproducible FFQ. Nutrient intakes were estimated using a food composition database. RESULTS: Twenty-eight articles regarding 32 distinct study populations were included. Maternal nutrient intakes were generally in agreement across studies included in the SR and conforming to DRVs. Within micronutrients, vitamin D intake was below the recommendation. In the MEDIDIET study, mean intakes of energy (1950 ± 445 kcal/d), carbohydrates (270 ± 20.1 g/d), proteins (87.8 ± 20.1 g/d), and fats (65.6 ± 18.9 g/d) were similar to those observed in the SR. Moreover, observed intakes seemed to reflect the typical Mediterranean diet, with low intakes of carbohydrates, SFAs, and PUFAs and high intakes of MUFAs and vitamins. Conversely, protein intake was mainly derived from animal sources. CONCLUSIONS: This SR showed that nutrient intakes of breastfeeding mothers in developed countries are generally in line with DRVs despite different dietary patterns worldwide. Some nutritional deficiencies emerged, highlighting the need for additional nutritional advice. Mothers participating in the MEDIDIET study showed a nutritional profile in agreement with the Mediterranean diet.

OBJECTIVES: Dietary patterns are a useful tool to study the impact of overall maternal diet on human milk (HM) composition beyond single foods or nutrients. The present study aimed to identify dietary patterns among Chinese lactating women and assess their associations with HM macronutrient composition. METHODS: Dietary intake data and HM samples were collected from 122 Chinese mothers at three to five study visits during the first 52 d postpartum. Dietary patterns were derived using principal component analysis. Cross-sectional associations of dietary patterns and HM macronutrients were assessed using multivariable linear regression models adjusted for total energy intake. All analyses were done separately for colostrum (postpartum days 0-7) and mature milk (postpartum days 8-52). RESULTS: Four dietary patterns were identified: high-in-animal-foods, high-in-eggs, high-in-plant-foods, and high-in-fruits. Compared with the lowest tertile (T1), participants in the highest tertile (T3) of the high-in-animal-foods and high-in-plant-foods patterns had lower protein (respectively, T3 - T1 = -1.09 g/100 mL, Ptrend = 0.002; T3 - T1 = -0.54 g/100 mL, Ptrend = 0.001) and higher fat (respectively, T3 - T1 = 0.86 g/100 mL, Ptrend = 0.040; T3 - T1 = 0.40 g/100 mL, Ptrend = 0.004) concentrations in colostrum. In contrast, in mature milk the high-in-animal-foods pattern was positively associated with carbohydrates (T3 - T1 = 0.53 g/100 mL, Ptrend = 0.008) and the high-in-plant-foods pattern was negatively associated with fat (T3 - T1 = -0.64 g/100 mL, Ptrend = 0.002). The high-in-eggs pattern was weakly positively associated with protein concentration in mature milk (T3 - T1 = 0.10 g/100 mL, Ptrend = 0.023). CONCLUSIONS: Maternal dietary patterns with high proportions of animal and plant-based foods were associated with higher fat and lower protein concentrations in colostrum. Different associations were found in mature milk. Dietary-pattern analysis provides an opportunity to characterize total diet and may be more predictive of HM composition than single foods or nutrients.

(1) Background: Several studies have reported associations between maternal diet in terms of single foods or nutrients and human milk compounds, while the overall role of maternal diet and related dietary patterns has rarely been investigated. (2) Methods: Between 2012 and 2014, we enrolled 300 healthy Italian mothers, who exclusively breastfed their infant. During a hospital visit at 6 weeks postpartum, a sample of freshly expressed foremilk was collected and information on maternal dietary habits in the postpartum period was obtained through an interviewer-administered food frequency questionnaire. We applied principal component factor analysis to selected nutrients in order to identify maternal dietary patterns, and assessed correlations in human milk macronutrients and fatty acids across levels of dietary patterns. (3) Results: Five dietary patterns were identified, named "Vitamins, minerals and fibre", "Proteins and fatty acids with legs", "Fatty acids with fins", "Fatty acids with leaves", "Starch and vegetable proteins". These dietary patterns were correlated with some milk components, namely fatty acids, and in particular ω-3 and its subcomponents. (4) Conclusions: This study showed that overall maternal dietary habits during breastfeeding may influence human milk composition, suggesting the importance of adequate maternal nutrition during lactation not only for the mother herself but also to provide the infant with milk containing adequate amount and quality of nutrients for a balanced nutrition.

Retrospective chart reviews have reported hypophosphatemia associated with elemental formula use in infants and children with systemic disease involving multiple diagnoses. The present study aims to evaluate the bioavailability of phosphorus from 2 commercial elemental formulas and to test our hypothesis of bioequivalence of the 2 products in healthy volunteers receiving gastric acid-suppressive medication. A single-center, double-blind, randomized, cross-over study was conducted in healthy volunteers with esomeprazole-induced hypochlorhydria. After a standardized low phosphorus meal followed by overnight fasting, subjects consumed 1 gram of phosphorus in a single oral dose of 1217 kcal of Product A (Neocate) or Product B (Elecare). The alternate product was given following a 1-week washout period. Blood and urine were collected at baseline and different time-points for up to 6 hours after product consumption. Area-under-the-curve (AUC) and peak values (Cpeak) for serum phosphate and calcium and urinary creatinine-corrected phosphate and calcium were assessed for bioequivalence of Products A and B. Results show that the geometric mean ratio (GMR) and 90% CI for serum phosphate were 1.041 (0.998-1.086) and 1.020 (0.963-1.080) for AUC0-360 and Cpeak, respectively, meeting the predetermined criteria for bioequivalence. Urinary creatinine-corrected phosphate followed a similar pattern after intake of Product A and B, but did not reach bioequivalence criteria (GMR: AUC70-370 = 1.105 (0.918-1.330); Cpeak = 1.182 (1.040-1.343)). Serum calcium concentrations (GMR: AUC0-360 = 1.002 (0.996-1.009); Cpeak = 0.991 (0.983-0.999)) and urinary creatinine-corrected calcium excretion (GMR: AUC70-370 = 1.117 (1.023-1.219); Cpeak = 1.157 (1.073-1.247)) demonstrated bioequivalence of the products. In conclusion, both elemental infant formulas showed equivalent serum phosphorus and calcium bioavailability in healthy volunteers even if combined with treatment with acid-suppressive medication.

We determined the nutritional adequacy and overall quality of the diets of adult patients with eosinophilic esophagitis (EoE). Dietary intakes stratified by sex and age were compared to Dietary Reference Values (DRV). Overall diet quality was assessed by two independent Diet-Quality-Indices scores, the PANDiet and DHD-index, and compared to age- and gender-matched subjects from the general population. Lastly, food and nutrient intakes of EoE patients were compared to intakes of the general population. Saturated fat intake was significantly higher and dietary fiber intake significantly lower than the DRV in both males and females. In males, the DRV were not reached for potassium, magnesium, selenium, and vitamins A and D. In females, the DRV were not reached for iron, sodium, potassium, selenium, and vitamins A, B2, C and D. EoE patients had a significantly lower PANDiet and DHD-index compared to the general population, although the relative intake (per 1000 kcal) of vegetables/fruits/olives was significantly higher (yet still up to 65% below the recommended daily amounts) and alcohol intake was significantly lower compared to the general Dutch population. In conclusion, the composition of the habitual diet of adult EoE patients has several pro-inflammatory and thus unfavorable immunomodulatory properties, just as the general Dutch population, and EoE patients had lower overall diet quality scores than the general population. Due to the observational character of this study, further research is needed to explore whether this contributes to the development and progression of EoE.

Omega-3 long-chain polyunsaturated fatty acid (n-3 FA) status may be associated with mood disorders. Here, we evaluated the potential association between antenatal depression/anxiety and n-3/n-6 FA in (a) maternal erythrocytes and (b) human milk. In addition, we explored associations between n-3/n-6 FA in erythrocytes and in human milk and postpartum depression, while controlling for antenatal depression. Twenty-seven pregnant women diagnosed with a current major depressive disorder (MDD; n = 9), anxiety disorder (AD; n = 10) or a mixed anxiety-depression disorder (MADD; n = 8), and 40 healthy controls were included. n-3/n-6 FA were determined in maternal erythrocytes in gestational week 32 and in human milk in postpartum week 1. In the first week postpartum, the Edinburgh-Postnatal-Depression-Questionnaire was used to assess postpartum depression. Results show that women with M(A)DD had significantly lower erythrocyte levels of total n-3 FA, EPA, DHA and DGLA, and significantly higher n-6 DPA, and n-6:n-3, AA:EPA and n-6 DPA:DHA ratios compared to healthy controls. No significant associations between antenatal depression or anxiety and n-3/n-6 FA in human milk were found. After controlling for antenatal mental health, n-3/n-6 FA in maternal erythrocytes or in human milk were not significantly associated with postpartum depression. In conclusion, antenatal depression, alone or with an anxiety disorder, was associated with lower n-3 FA levels and higher n-6:n-3 FA ratios in maternal erythrocytes during gestation. This study provides some insights into the associations between n-3/n-6 FA levels during pregnancy and lactation and perinatal mental health.

Data on the mineral status of infants with cow's milk allergy (CMA) consuming an amino acid-based formula (AAF) have not been published. The present study aims to assess mineral status of term infants age 0 to 8 months diagnosed with CMA receiving an AAF for 16 weeks. Serum concentrations of calcium, phosphorus, chloride, sodium, potassium, magnesium, and ferritin were determined in 82 subjects at baseline and in 66 subjects after 16 weeks on AAF using standard methods and evaluated against age-specific reference ranges. In addition to this, individual estimated energy and mineral intakes were compared to Adequate Intakes defined by the European Food Safety Authority and the US Institute of Medicine. The results of this study show that the AAF was effective in providing an adequate mineral status in infants with CMA. The vast majority of infants aged 0 to 6 months (formula only) and aged 6 to 12 months (formula and complementary foods) had adequate mineral intakes.

BACKGROUND AND AIM: Iron deficiency (ID) and vitamin D deficiency (VDD) are the 2 most common micronutrient deficiencies in young children worldwide and may lead to impaired neurodevelopment and rickets, respectively. Risk factors for ID and VDD differ between populations. The objective of this study was to determine the prevalence of and risk factors for ID and VDD in 12- to 36-month-old children in Western Europe. METHODS: This study took place in Germany, the Netherlands, and the United Kingdom from 2012 to 2014. A venous blood sample was taken to establish iron and vitamin D status. ID was defined as serum ferritin <12 µg/L in the absence of infection (high sensitivity C-reactive protein <10 mg/L). VDD was defined as serum 25-hydroxyvitamin D <50 nmol/L (20 ng/mL). Furthermore, parents were asked to fill out a questionnaire regarding their child's demographic- and socioeconomic characteristics, food intake, sun exposure, and medical history. RESULTS: In 325 children (white race 95%, boys 56%, mean age 20.7 months) the overall prevalence of ID and VDD was 11.8% and 22.8%, respectively. The use of primarily cow's milk as major type of milk was associated with ID (odds ratio [OR] 3.20, 95% confidence interval [CI] 1.12-8.53) and VDD (OR 7.17, 95% CI 3.10-16.57). The use of vitamin D supplements (OR 0.20, 95% CI 0.07-0.56) was associated with a lower prevalence of VDD. CONCLUSION: Despite current nutritional recommendations, ID and VDD are common in healthy young white children. Health programs focusing on adequate iron and vitamin D intake at an early age should be implemented to prevent deficiencies.

BACKGROUND: Research into the role of young-child formulae (YCF) in a child's diet is limited and there is no consensual recommendation on its use. We evaluated the theoretical nutritional impact of replacing the existing practice of consuming cow's milk by YCF. METHODS: From the UK Diet and Nutrition Survey of Infants and Young Children, whole cow's milk consumers, aged 12-18 months (n = 591) were selected for simulation scenarios. In Scenario 1, we tested the replacement of all whole cow's milk (434 ± 187 ml/day) by a matching volume of YCF, and in Scenario 2, all whole cow's milk was replaced by the on-pack recommended daily intake of 300 ml. Nutrient intakes before and after simulation scenarios were compared and evaluated against nutrient recommendations. RESULTS: Intakes of protein and saturated fatty acids were significantly decreased, whereas essential fatty acid intakes were increased. The prevalence of nutrient inadequacy before simulation was 95.2% for vitamin D and 53.8% for iron. After simulation, inadequacy decreased to 4.9% (Scenario 1) and 0% (Scenario 2) for vitamin D and to 2.7% (Scenario 1) and 1.1% (Scenario 2) for iron. CONCLUSIONS: Replacement of habitual cow's milk intake by a matching volume or 300 ml of YCF may lead to nutritional intakes more in line with recommendations in young children.

The early years of life are a period of very rapid growth and development. In this critical phase, food preferences are formed which carry over into childhood and beyond and foundations are laid for a healthy adult life. Excess energy, imbalances in macronutrient quality, and nutritional deficiencies may form inappropriate nutritional signals, leading to metabolic disturbances and affecting the obesity risk. For instance, the intake of protein and sugar-sweetened beverages in young children has been associated with an increased risk of overweight and obesity. In reality, scientific reports have shown that the dietary intakes of vegetables, α-linolenic acid, docosahexaenoic acid, iron, vitamin D, and iodine are low and the intakes of protein, saturated fatty acids, and added sugar are high in young children living in Europe. A focus on improving feeding habits and approaches to support more balanced nutritional intakes early in life may have significant public health benefits.
