Abstract
β-Lactoglobulin (BLG) is an allergen present in milk that can induce an acute immune response in certain individuals. The successful use of cytosine base editors (CBEs) can introduce stop codons into premature mRNA, thereby generating animals with disrupted genes that negatively regulate target traits. In this study, we employed a CBE system to target the major milk allergen BLG in bovine embryos, mammary epithelial cells, and live cattle. First, the precise single-base editing of the BLG gene in bovine embryos was achieved by designing an effective sgRNA to induce a c.61C > T substitution in the coding region, converting codon 21Gln (p.21Gln) to a premature stop codon. Sanger sequencing revealed an editing efficiency of 83.3% (20 out of 24 embryos), including two homozygous edits. Second, a bovine mammary epithelial cell line harboring BLG edits was constructed using the same CBE system. Sequencing showed that the designed sgRNA1 enabled the simultaneous conversion of three consecutive cytosines (c.59-61CCC > TTT) to thymines. At position c.61, single-cell clones exhibited monoallelic or biallelic editing (BLGc.61C > T), with monoallelic edits at positions c.59 and c.60 (CC > TT). Gene expression analysis confirmed that the BLGc.61C > T mutation effectively suppressed BLG expression at both the mRNA and protein levels, even in monoallelically edited cells. Finally, we successfully generated a heterozygous BLGc.61C > T single-base-edited dairy cow that despite its heterozygosity, showed significantly reduced BLG expression in the mammary epithelial cells and milk. Collectively, this study demonstrates the feasibility of using CBEs to disrupt BLG expression in dairy cows and provides a foundation for application in generating hypoallergenic dairy products.

Hamulka J, Czarniecka-Skubina E, Górnicka M, Gębski J, Leszczyńska T, Gutkowska K. What Determinants Are Related to Milk and Dairy Product Consumption Frequency among Children Aged 10-12 Years in Poland? Nationwide Cross-Sectional Study. Nutrients 2024; 16:2654. [PMID: 39203791 PMCID: PMC11357169 DOI: 10.3390/nu16162654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2024] [Revised: 08/07/2024] [Accepted: 08/09/2024] [Indexed: 09/03/2024] Open
Abstract
Due to their high nutritional value, milk and dairy products should be a permanent element of a properly balanced diet for children and adolescents. The study aimed to identify (i) the frequency of milk and dairy product consumption by children aged 10-12 years in the opinion of children and their parents and (ii) the determinants related to the consumption of these products (including lifestyle, nutrition knowledge, and the nutritional status of children's as well as parents' nutrition knowledge). A cross-sectional study was conducted with 12,643 primary school students aged 10-12 and 7363 parents. Dietary data were collected using the Food Frequency Consumption and Nutritional Knowledge Questionnaire (SF-FFQ4PolishChildren® and KomPAN®). Anthropometric measurements were taken and body mass index (BMI) and waist/height ratios (WHtR) were calculated. A logistic regression model was used to assess the likelihood of the frequent consumption of dairy products in the opinion of both the children and their parents, and the quality of the obtained models was assessed using model fit statistics and the Hosmer and Lemeshow test. The frequency of consuming milk and milk products (every day and more) was low in the opinion of children aged 10-12 years (29.6%). According to their parents, the frequency of the consumption of dairy products was slightly higher (44.8%). Six factors associated with the frequency of milk and dairy product consumption were identified independently. These included schoolchildren and their parents' nutrition knowledge, physical activity, sleep, gender, and place of residence. More of these products were consumed by children with greater nutrition knowledge-both their own and their parents'-higher physical activity, longer sleep duration, males, and those living in the city. Family eating habits, particularly eating meals together, also played an important role in the consumption of milk and dairy products. According to the parents, the children in older grades were less likely to consume dairy products more frequently. The obtained results suggest an insufficient consumption of milk and dairy products. The identification of modifiable factors, such as nutrition knowledge, physical activity, sleep duration, and eating meals with the family, suggests the need to improve the existing strategies, including activities encouraging nutritional education for both schoolchildren and their parents.

Dietary Intake of Adolescents and Alignment with Recommendations for Healthy and Sustainable Diets: Results of the SI.Menu Study. Nutrients 2024; 16:1912. [PMID: 38931267 PMCID: PMC11206795 DOI: 10.3390/nu16121912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 06/07/2024] [Accepted: 06/12/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND The SI.Menu study offers the latest data on the dietary intake of Slovenian adolescents aged 10 to 17. The purpose of this study is to comprehensively assess their dietary intake (energy and nutrients) and compare their food intakes with dietary recommendations for healthy and sustainable diets. METHODS The cross-sectional epidemiological dietary study SI.Menu (March 2017-April 2018) was conducted on a representative sample of Slovenian adolescents aged 10 to 17 years (n = 468) (230 males and 238 females). Data on dietary intake were gathered through two non-consecutive 24 h recalls, in line with the European Food Safety Authority (EFSA) EU Menu methodology. The repeated 24 h Dietary Recall (HDR) and Food Propensity Questionnaire (FPQ) data were combined to determine the usual intakes of nutrients and food groups, using the Multiple Source Method (MSM) program. RESULTS Adolescents' diets significantly deviate from dietary recommendations, lacking vegetables, milk and dairy products, nuts and seeds, legumes, and water, while containing excessive meat (especially red meat) and high-sugar foods. This results in insufficient intake of dietary fibre, and nutrients such as vitamin D, folate, and calcium. CONCLUSIONS The dietary intake of Slovenian adolescents does not meet healthy and sustainable diet recommendations. This study provides an important insight into the dietary habits of Slovenian adolescents that could be useful for future public health strategies.

Abstract
The bovine milk quality, safety, and security are of great concern mainly due to the dispersion of toxic substances from various anthropogenic activities and poor practices for organophosphates in agriculture use. This study evaluated the potential risk to human health from lead (Pb), cadmium (Cd), and arsenic (As) from the consumption of milk produced in an area of the Central Andes valley near a mini mineral concentrator by estimating the weekly intake (WI), dietary risk quotient (DRC), hazard quotient (THQ), and hazard index (HI) for the Peruvian population aged 2 to 85 years, in three scenarios of milk consumption by age (minimum, average, and maximum). Toxic element quantification was performed by flame atomic absorption spectrometry following standardized procedures. The mean amount ± standard deviation of Pb, Cd, and As in soils was 292±60.90, 3.54±1.58, and 5.60±2.20 mg/kg, the order of importance being Pb>As>Cd. The contents of Pb, Cd, and As in pastures were 23.17±10.02, 0.25±0.57, and 0.06±0.09 mg/kg, being from highest to lowest Pb>Cd>As. The means of Pb, Cd, and As content in 19 milk samples were 0.029±0.022, 0.007±0.006, and 0.010±0.004 mg/kg. Pb and Cd exceeded the maximum permissible limits (MPL), and the As was below the MPL. At all ages and milk consumption levels, the WI for Pb and Cd were below the estimated tolerable intake (TWI). The WI for As in < 19 years was higher than the TWI. The DRC for Pb and Cd at all three milk intake levels and all ages was < 1, and for As, it was > 1 in < 19 years, being the risk group. The TQH and HI for Pb and Cd were also > 1, signifying no health risk, and for As, the values were > 1 in < 11 years. Our results are valuable for preventing adverse health impacts from safe and innocuous milk consumption.

Abstract
Introduction Despite being an excellent source of essential nutrients, whole cow's milk poses risks for young children. This is mainly due to its association with adverse effects, including growth inhibition, delayed brain and motor development, and increased morbidity and mortality. The current study aimed to evaluate the occurrence of untimely introduction of whole cow milk, stunting and related factors among children below the age of 5 years. Methods A community-centered survey was implemented on 806 mother-child matches. Expressive statistics such as frequency, magnitude, mean and standard deviation were computed. Multivariable logistic regression was done to discover independent determinants of the dependent variables. A p-value of <0.05 was used to affirm significant association. Results From the survey participant children 311 (39.2%) of them were stunted. About 453 (57.1%) of children were fed whole cow milk earlier than the age of one year. Mothers who are able to read and write were 49% less likely to initiate cow milk earlier than the age of one year with AOR = 0.51, 95% CI 0.33-0.78. Not attending the growth monitoring and promotion service is a risk for untimely introduction of whole cow milk (AOR = 3.47, 95% CI 2.43-4.94). Children who did not start consuming whole cow milk earlier than the age of one year were 54% less likely to be stunted than those who started consuming whole cow milk before the age of one year (AOR = 0.46, 95% CI 0.33-0.65). Conclusion More than half of the study participant children started consuming whole cow milk before the age of one year. Children who did not start consuming whole cow milk early were less likely to be stunted.

Abstract
Yogurt is a fermented milk product characterised by a peculiar nutritional composition with live and viable cultures of bacteria. Few studies have analysed the benefits of yogurt consumption on health outcomes during paediatric age. Recent epidemiological studies evaluating the nutritional impact of yogurt have demonstrated its significant contribution to nutrients intakes among children. Thus, consuming yogurt is a strategy to achieve recommended nutrient intake and healthier dietary choices, with potential impact on obesity and cardiometabolic outcome in children. Yogurt's effects on paediatric infectious diseases, gastrointestinal diseases and atopic-related disorders are ascribed to the specific probiotic strain administered. Interestingly, the benefits of yogurt consumption are most likely due to effects mediated through the gut microbiota and the enhancement of innate and adaptive immune responses. Therefore, supplementing standard yogurt cultures with probiotic strains could be useful to promote health at different paediatric ages, although more evidence is needed regarding the strain-related effects and their interplay within the paediatric immune system.

Abstract
Iron-deficiency anaemia is a widespread and largely preventable problem in the paediatric population, with numerous potential sequelae. We describe the case of a 2-year-old girl presenting with non-specific symptoms, who was found to be iron-deficient and anaemic, in the context of excessive cow's milk consumption. We explore the patient's diagnostic journey, including a neurological deterioration and the link between her iron deficiency and the final diagnosis.

Abstract
Human type 1 diabetes mellitus is a chronic autoimmune disease characterized by the selective loss of insulin-producing β-cells in pancreatic islets of genetically susceptible individuals. In this communication, a new hypothesis is postulated which is based on the observations that streptozotocin (STZ), a chemically reactive and cytotoxic compound produced by certain gram-positive bacteria, can be preferentially taken up into islet β-cells and induce cytotoxicity and autoimmunity. It is hypothesized that humans might be occasionally exposed to STZ through opportunistic infections with the STZ-producing bacteria and/or through ingestion of certain food products that contain STZ. In addition, the potential presence of the STZ-producing bacteria in the gut microbiota of some individuals might be another source of long-term STZ exposure. Because of the high chemical reactivity of STZ and its breakdown products, these chemicals can covalently modify certain cellular macromolecules (e.g., DNA and proteins), and the covalently modified cellular components would serve as new antigens, potentially capable of inducing both humoral and cellular autoimmune responses in the islets of certain individuals. In addition to STZ exposure, the eventual development of autoimmunity against STZ-exposed islet β-cells also depends critically on the genetic predisposition of the susceptible individuals plus the opportunistic presence of a conducive, strong environmental trigger, which often is presented as severe febrile viral infections subsequently inducing strong aberrant reactions of the body’s immune system. The proposed pathogenic hypothesis is supported by a considerable body of direct and indirect evidence from laboratory animal studies and clinical observations. Certainly, more experimental and clinical studies are needed to carefully further examine each of the key components of the proposed pathogenic hypothesis.

Abstract
Milk is widely considered as a beneficial product for growing children. This study was designed to describe the milk consumption status of Korean children aged 30–36 months and to investigate its association with the risk of obesity and iron deficiency anemia (IDA). This nationwide administrative study used data from the Korean national health insurance system and child health screening examinations for children born in 2008 and 2009. In total, 425,583 children were included, and they were divided into three groups based on daily milk consumption: low milk group (do not drink or drink <200 mL milk per day, n = 139,659), reference group (drink 200–499 mL milk per day, n = 255,670), and high milk group (drink ≥500 mL milk per day, n = 30,254). After adjusting variable confounding factors, the consumption of a large amount of milk of ≥500 mL per day at the age of 30–36 months was associated with an increased risk of obesity at the age of 42–72 months and IDA after the age of 30 months. These results may provide partial evidence for dietary guidelines for milk consumption in children that are conducive to health.

Abstract
The mining-metallurgical industry in the central Andes of Peru is a source of lead (Pb) and cadmium (Cd) contamination in milk, and there are no studies on the impact of their ingestion. Using flame atomic absorption spectrometry, we quantified the concentration of these metals in raw milk produced in agroecological zones near these industries, and estimated the exposure and dietary risk in people aged 2-85 yr with minimum, average and maximum daily milk intake. In 2018, 40 raw milk samples were collected from 20 cows at two times of the year. The mean Pb and Cd concentrations were 577 ± 18.2 and 18.35 ± 5.4 μg/kg, all samples exceeded the maximum limits (ML). Children aged 2-5 and 6-15 yr, with average milk consumption, had Pb weekly intakes (WI) of 2019 and 2423 μg, exceeding the risk value; values for Cd 64 and 77 μg were below the risk values. In those older than 20 years the WI for both metals are below the risk values. The Dietary Risk Coefficient (DRC) to Pb in children younger than 8 years was >3 due to higher milk consumption in relation to body weight; for children aged 9-19 years it was 1.7 and 2.9, being <1 for those older than 20 yr. Cd RDCs were <1 at all ages, with the exception of 2-year-olds in the high milk consumption scenario (RDC > 1). There was notable evidence of Pb and Cd exposure risk from consumption of milk produced near mining-metallurgical activities, predominantly for children under 19-year-olds. In Peru there are no regulations for Pb and Cd in fresh milk and milk products, we recommended that ML for heavy metals in food be established.

Abstract
Systemic iron homeostasis is regulated by the interaction of the peptide hormone, hepcidin and the iron exporter, ferroportin. The objective was to investigate the relationship between the consumption of cow's milk and iron deficiency anemia in children 2-10 years old and its association with the hepcidin-25 and ferroportin concentrations. The study population consisted of 187 prepubescent children of similar ideal body weight (IBW:90-120%); 82 children with iron deficiency anemia (37girls and 45boys; 4.27 ± 0.28 years) and 105 (47girls and 58boys; 4.25 ± 0.34 years) healthy age-sex-matched controls. Serum fasting hepcidin-25/ferroportin concentrations were measured by enzyme immunoassay in all subjects. Mean cow's milk consumption in the anemic group (373 ± 248 mL/d) tended to be higher than that in the control group (320 ± 226 mL/d), but the result was not statistically significant (p = 0.063).The mean hepcidin-25 level was significantly higher in the anemic group (19.5 ± 18.4 ng/mL) than in the healthy controls (11.0 ± 10.7, p < 0.001). The mean ferroportin level was lower in the anemic group (21.04 ± 5.74 ng/mL) than in the healthy controls (22.68 ± 4.77 ng/ml, p = 0.037). Consuming cow's milk was not associated with IDA in prepubertal children, provided that it was adequately supplemented with iron-enriched foods. We observed a significant increase in hepcidin-25 levels and a decrease in ferroportin levels in children with iron deficiency anemia compared with healthy controls. Children who consumed more cow's milk had higher levels of hepcidin-25. Iron deficiency anemia is not a concern when cow's milk is given to children if the complementary foods are rich in iron.

Abstract
Human milk is compatible with infant intestinal microbiota and is vital for infant health. However, most infants do not receive sufficient exclusive breastfeeding, and the effects of including other types of animal milk on the gut microbiota of infants are unclear. Therefore, the objective of this study was to elucidate the impact of milk from various animal sources on infant fecal microbiota through in vitro fermentation. The types of milk assessed include cow milk, goat milk, camel milk, mare milk, human milk, and infant formula milk. Here we determined the gas pressure, pH, and microbiota after 24 h fermentation. Results showed that mare milk had the lowest gas pressure rating, with levels similar to human milk. More so, pH analysis demonstrated that other milk types were identical to human milk. Bacterial 16S rRNA gene sequence analysis revealed that all milk types increased the abundance of Bifidobacterium and Lactobacillus, which was proportional to the lactose content of milk. Moreover, mare milk also significantly increased the relative abundance of Akkermansia. Collectively, results from mare milk (gas pressure, pH, and microbiota) were comparable to that of human milk, and thus support the theoretical basis for exploring the development of a mare milk-based infant formula.

The effect of consuming milk and related products during human pregnancy over birth weight and perinatal outcomes: A systematic review and meta-analysis. Eur J Obstet Gynecol Reprod Biol 2020; 251:235-245. [PMID: 32554191 DOI: 10.1016/j.ejogrb.2020.05.061] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 05/26/2020] [Accepted: 05/29/2020] [Indexed: 12/17/2022]
Abstract
OBJECTIVE Data addressing the effect of milk and related products (M&RPs) on fetal growth are contradictory. The aim was to meta-analyze the effect of consuming M&RPs during human pregnancy over perinatal outcomes. METHOD A systematic literature search was performed in PubMed, EMBASE, Scopus, Web of Science, and Cochrane Library. Eligibility criteria for selection were: studies evaluating the effect of consuming M&RPs during pregnancy over birth weight and different perinatal outcomes. Random effect models were used for meta-analyses, and effects are reported as mean differences (MD) or odds ratio (OR) and their 95 % confidence intervals (CIs). RESULTS Fourteen studies (111,184 pregnant women) reported on the targeted perinatal outcomes. The meta-analysis of ten studies revealed a positive association between consuming a higher amount of M&RPs and birth weight (MD =51.0 g, 95 % CI 24.7-77.3), whereas in five studies a positive effect was observed on infant length (MD =0.33 cm, 95 % CI: 0.03-0.64). The higher birth weight was detected both in Western world gravids, consuming standard/conventional diets, as well as in vegetarian women from India. There were no significant differences in ultrasound measured fetal head circumference, biparietal diameter, abdominal circumference and femur length. The consumption of a higher amount of M&RPs was associated with a reduced risk of small-for-gestational age (SGA) (OR = 0.69, 95 % CI: 0.56-0.84) and low birth weight infants (OR = 0.63, 95 % CI: 0.48-0.84); in addition to a higher risk of large-for-gestational age (LGA) infants (OR = 1.11, 95 % CI: 1.02-1.21). CONCLUSION The consumption of a higher amount of M&RPs during pregnancy was associated with greater infant birth weight and length; in addition to a lower risk of having SGA and low birth weight infants, and a higher risk of LGA infants.

Abstract
This study was conducted to address the dearth in works that simultaneously compare the growth and inactivation behaviors of selected pathogens in different milk products. In worst-case scenarios where hygienic practices are absent and heavy microbiological contaminations occur, Salmonella enterica, Escherichia coli O157:H7, Listeria monocytogenes, Pseudomonas aeruginosa, and Staphylococcus aureus multiplied in all samples at room temperature (27 °C). Most organisms readily proliferated with growth lag (tlag) values ranging from 0.00 to 5.95 h. Growth rates (KG) ranged from 0.16 to 0.67 log CFU/h. Sanitary risk times (SRTs) for a 1-log population increase ranged from 1.85 to 6.27 h, while 3.69-12.55 h were the SRTs determined for 2-log population increase. Final populations (Popfin) ranged from 7.11 to 9.36 log CFU/mL. Inactivation in heavily contaminated milk during Holder pasteurization revealed biphasic inactivation behavior with total log reduction (TLR) after exposure to 62.5 °C for 30 min ranging from 1.91 (90.8%) to 6.00 (99.9999%). These results emphasize the importance food safety systems in the handling of milk and milk products during manufacture and preparation.

The Importance of Lactose in the Human Diet: Outcomes of a Mexican Consensus Meeting. Nutrients 2019; 11:E2737. [PMID: 31718111 PMCID: PMC6893676 DOI: 10.3390/nu11112737] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 11/04/2019] [Accepted: 11/08/2019] [Indexed: 12/12/2022] Open
Abstract
Lactose is a unique component of breast milk, many infant formulas and dairy products, and is widely used in pharmaceutical products. In spite of that, its role in human nutrition or lactose intolerance is generally not well-understood. For that reason, a 2-day-long lactose consensus meeting with health care professionals was organized in Mexico to come to a set of statements for which consensus could be gathered. Topics ranging from lactase expression to potential health benefits of lactose were introduced by experts, and that was followed by a discussion on concept statements. Interestingly, lactose does not seem to induce a neurological reward response when consumed. Although lactose digestion is optimal, it supplies galactose for liver glycogen synthesis. In infants, it cannot be ignored that lactose-derived galactose is needed for the synthesis of glycosylated macromolecules. At least beyond infancy, the low glycemic index of lactose might be metabolically beneficial. When lactase expression decreases, lactose maldigestion may lead to lactose intolerance symptoms. In infancy, the temporary replacing of lactose by other carbohydrates is only justified in case of severe intolerance symptoms. In those who show an (epi)genetic decrease or absence of lactase expression, a certain amount (for adults mostly up to 12 g per portion) of lactose can still be consumed. In these cases, lactose shows beneficial intestinal-microbiota-shaping effects. Avoiding lactose-containing products may imply a lower intake of other important nutrients, such as calcium and vitamin B12 from dairy products, as well as an increased intake of less beneficial carbohydrates.

Abstract
Background The existing evidence is limited and contradicting on the co-occurrence of anemia and stunting (CAS) at individual level, despite a great overlap in their risk factors. We aimed to determine the prevalence of CAS, and the dietary and non-dietary factors associated with it, among infants and young children in Ethiopia. Method We used a nationally representative sample of 2902 children aged 6–23 months from the Ethiopian demographic and health survey, conducted in 2016. The study was cross-sectional in design. Samples were selected by two-stage clustering sampling method. CAS prevalence was estimated by various sociodemographic factors. To identify the dietary and non-dietary factors associated with CAS, we conducted hierarchical logistic regression analyses. Result The overall prevalence of CAS was 23.9%. The dietary factors found significantly linked to lower odds of CAS were use of vitamin A supplement [adjusted odds ratio (AOR) = 1.19, 95%CI = 1.06–1.33, P = 0.003], consumption of vitamin A rich fruit and vegetables (AOR = 1.15, 95%CI = 1.04–1.27, P = 0.006), meat (AOR = 1.55, 95%CI = 1.17–2.05, P = 0.002), legumes (AOR = 1.38, 95%CI = 1.05–1.81, P = 0.021), and meal frequency > 3 (AOR = 1.22, 95%CI = 1.04–1.37, P = 0.020). The non-dietary household and child factors found significantly linked to higher odds of CAS were rural residence (AOR = 1.29, 95%CI = 1.18–1.41, P < 0.001), low household wealth (AOR = 1.91, 95%CI = 1.53–2.39, P < 0.001), low caregivers’ education level (AOR = 2.14, 95%CI = 1.33–3.44, P < 0.001), male sex (AOR = 1.25, 95%CI = 1.04–1.50, P = 0.015), age 12–23 months (AOR = 1.65, 95%CI = 1.57–1.73, P < 0.001), history of infection (AOR = 1.14, 95%CI = 1.00–1.30, P = 0.048), and small birth size (AOR = 1.99, 95%CI = 1.58–2.51, P < 0.001). Conclusion Among infants and young children in Ethiopia, there was a concerning high level of CAS, which was associated with various dietary and non-dietary factors. Enhanced public health/nutrition interventions, with due emphasis on the multifactorial nature of CAS, might stand an important consideration to reduce the burden of CAS in Ethiopia and beyond.

Abstract
BACKGROUND A considerable body of evidence accumulated especially during the last decade, demonstrating that early nutrition and lifestyle have long-term effects on later health and disease ("developmental or metabolic programming"). METHODS Researchers involved in the European Union funded international EarlyNutrition research project consolidated the scientific evidence base and existing recommendations to formulate consensus recommendations on nutrition and lifestyle before and during pregnancy, during infancy and early childhood that take long-term health impact into account. Systematic reviews were performed on published dietary guidelines, standards and recommendations, with special attention to long-term health consequences. In addition, systematic reviews of published systematic reviews on nutritional interventions or exposures in pregnancy and in infants and young children aged up to 3 years that describe effects on subsequent overweight, obesity and body composition were performed. Experts developed consensus recommendations incorporating the wide-ranging expertise from additional 33 stakeholders. FINDINGS Most current recommendations for pregnant women, particularly obese women, and for young children do not take long-term health consequences of early nutrition into account, although the available evidence for relevant consequences of lifestyle, diet and growth patterns in early life on later health and disease risk is strong. INTERPRETATION We present updated recommendations for optimized nutrition before and during pregnancy, during lactation, infancy and toddlerhood, with special reference to later health outcomes. These recommendations are developed for affluent populations, such as women and children in Europe, and should contribute to the primary prevention of obesity and associated non-communicable diseases.

Abstract
BackgroundBacterial infections account for a significant proportion of neonatal and infant mortality globally. We aimed to identify predictors of death in infants with probable serious bacterial infection (PSBI) defined as signs/symptoms of possible serious bacterial infection along with baseline C-reactive protein (CRP) ≥12 mg/l.MethodsWe did a secondary analysis using the data collected from 700 infants with PSBI who participated in a randomized controlled trial in India in which zinc or placebo was given in addition to the standard antibiotics. Logistic regression was used to estimate the associations between relevant variables and death within 21 days.ResultsThose infants who were fed cow's milk or formula before the illness episode had 3.7-fold (95% confidence interval (CI) 1.5-9.3) and 5.3-fold (95% CI 2.0-13.6) higher odds of death, respectively. Lethargy (odds ratio (OR) 2.4, 95% CI 1.1-5.4) and CRP (OR 1.9, 95% CI 1.1-3.3) were also independent predictors of death. In the model including only clinical features, female gender (OR 2.25, 95% CI 1.0-5.0), abdominal distention (3.7, 95% CI 1.1-12.3), and bulging fontanelle (5.8, 95% CI 1.1-30.5) were also independent predictors for death.ConclusionFormula or cow milk feeding prior to the illness, lethargy at the time of presentation, and high serum CRP levels predicted death in infants with PSBI.

Abstract
There is accumulating evidence that milk shapes the postnatal metabolic environment of the newborn infant. Based on translational research, this perspective article provides a novel mechanistic link between milk intake and milk miRNA-regulated gene expression of the transcription factor p53 and DNA methyltransferase 1 (DNMT1), two guardians of the human genome, that control transcriptional activity, cell survival, and apoptosis. Major miRNAs of milk, especially miRNA-125b, directly target TP53 and complex p53-dependent gene regulatory networks. TP53 regulates the expression of key genes involved in cell homeostasis such as FOXO1, PTEN, SESN1, SESN2, AR, IGF1R, BAK1, BIRC5, and TNFSF10. Nuclear interaction of p53 with DNMT1 controls gene silencing. The most abundant miRNA of milk and milk fat, miRNA-148a, directly targets DNMT1. Reduced DNMT1 expression further attenuates the activity of histone deacetylase 1 (HDAC1) involved in the regulation of chromatin structure and access to transcription. The presented milk-mediated miRNA-p53-DNMT1 pathway exemplified at the promoter regulation of survivin (BIRC5) provides a novel explanation for the epidemiological association between milk consumption and acne vulgaris and prostate cancer. Notably, p53- and DNMT1-targeting miRNAs of bovine and human milk survive pasteurization and share identical seed sequences, which theoretically allows the interaction of bovine miRNAs with the human genome. Persistent intake of milk-derived miRNAs that attenuate p53- and DNMT1 signaling of the human milk consumer may thus present an overlooked risk factor promoting acne vulgaris, prostate cancer, and other p53/DNMT1-related Western diseases. Therefore, bioactive miRNAs of commercial milk should be eliminated from the human food chain.

Abstract
AbstractObjectiveThe present study aimed to develop and validate a nutrition knowledge questionnaire in a sample of French Canadians from the province of Quebec, taking into account dietary guidelines.DesignA thirty-eight-item questionnaire was developed by the research team and evaluated for content validity by an expert panel, and then administered to respondents. Face validity and construct validity were measured in a pre-test. Exploratory factor analysis and covariance structure analysis were performed to verify the structure of the questionnaire and identify problematic items. Internal consistency and test–retest reliability were evaluated through a validation study.SettingOnline survey.SubjectsSix nutrition and psychology experts, fifteen registered dietitians (RD) and 180 lay people participated.ResultsContent validity evaluation resulted in the removal of two items and reformulation of one item. Following face validity, one item was reformulated. Construct validity was found to be adequate, with higher scores for RDv. non-RD (21·5 (sd2·1)v. 15·7 (sd3·0) out of 24,P<0·001). Exploratory factor analysis revealed that the questionnaire contained only one factor. Covariance structure analysis led to removal of sixteen items. Internal consistency for the overall questionnaire was adequate (Cronbach’sα=0·73). Assessment of test–retest reliability resulted in significant associations for the total knowledge score (r=0·59,P<0·001).ConclusionsThis nutrition knowledge questionnaire was found to be a suitable instrument which can be used to measure levels of nutrition knowledge in a Canadian population. It could also serve as a model for the development of similar instruments in other populations.

Abstract
We compared anthropometric values, nutrient intake, the Healthy Eating Index and food variety in children with autism spectrum disorder (ASD), 20 on a gluten-free casein-free (GFCF) diet and 85 on a regular diet in Valencia (Spain) using 3-days food diaries. Those on the GFCF diet had a lower weight, body mass index, and total energy, pantothenic acid, calcium, phosphorus and sodium intake, but a higher intake of fiber, legumes, and vegetables. Further, the GFCF diet group had a better quality of fat intake, but needed supplementation with vitamin D. Randomized controlled trials are required to explore long-term effects of this diet on anthropometric and nutritional status (the focus of our study), but also behavioral symptoms, in children with ASD.

Abstract
Objective: Iron and folic acid are essential nutrients needed for hematopoiesis. Infants’ diet is commonly deficient in these micronutrients that lead to nutritional anemia. Aim of this study was to determine serum iron, serum ferritin and red cell folate levels among healthy breast fed, fortified milk and cow’s milk fed infants. Methods: A total of 120 infants of 4-9 months of age were enrolled in this study. It included 40 normal breast fed controls, 40 fortified milk fed (FM) and 40 cow’s milk fed (CM) infants. Serum iron, serum ferritin and red cell folate concentrations were determined using colorimetric and enzyme immunoassay techniques. Results: Mean serum iron, serum ferritin and red cell folate concentrations of breast fed control group were 120.9±68.4µg/dl, 109±71.7ng/ml and 1044.1±409.2ng/ml respectively. Fortified milk (FM) group showed significantly decreased serum iron (p<0.003) as compared with controls whereas serum ferritin and red cell folate values showed insignificant change (p=0.25 and p=0.85 respectively). However serum iron, serum ferritin and red cell folate were significantly decreased in cow’s milk fed (CM) group as compared with control subjects (p<0.04, p<0.006, p<0.02 respectively). Comparison of these biochemical parameters between FM and CM groups showed statistically significant difference of serum ferritin and red cell folate among cow’s milk group (p<0.0001 and p<0.02) whereas serum iron level showed no significant difference, a p-value being 0.38. Conclusion: Healthy breast fed infants do not need any supplementation and fortification of iron and folic acid. Fortified milk appears to be an acceptable alternative in the absence of breast milk whereas cow’s milk is a poor source of iron and folic acid in infants.

Abstract
In autism spectrum disorders, many parents resort to alternative treatments and these are generally perceived as risk free. Among these, the most commonly used is the gluten-free, casein-free diet. The objective of this work was to conduct a systematic review of studies published from 1970 to date related to the gluten-free, casein-free diet in autism spectrum disorder patients. Few studies can be regarded as providing sound scientific evidence since they were blinded randomized controlled trials, and even these were based on small sample sizes, reducing their validity. We observed that the evidence on this topic is currently limited and weak. We recommend that it should be only used after the diagnosis of an intolerance or allergy to foods containing the allergens excluded in gluten-free, casein-free diets. Future research should be based on this type of design, but with larger sample sizes.

Abstract
The objective of this review was to summarize selected health aspects of protein intake during the first 2 y of life. During this period there is a marked increase in protein intake from an intake of ∼ 5% of energy from protein (PE%) in an exclusively breastfed infant to ∼ 15 PE% when complementary foods have been introduced. At this age, mean protein intake is ∼ 3 times as high as the physiologic requirement, but some children receive 4-5 times their physiologic requirement. Protein from cow milk constitutes a main part of protein intake in toddlers and seems to have a specific effect on insulin-like growth factor I concentrations and growth. Meat has a high protein content, but the small amounts of meat needed to ensure good iron status have less impact on total protein intake. The difference in protein intake between breastfed and formula-fed infants is likely to play a role in the difference between breastfed and formula-fed infants. There is emerging evidence that high protein intake during the first 2 y of life is a risk factor for later development of overweight and obesity. It therefore seems prudent to avoid a high protein intake during the first 2 y of life. This could be accomplished by decreasing the upper allowable limit of the protein content of infant formulas for the first year of life and limiting the intake of cow milk in the second year of life.

Abstract
A complete blood cell count (CBC) is a frequent test sent to aid in the diagnostic evaluation of ill patients. Not uncommonly hematologic abnormalities may be the first sign of an underlying systemic disorder. The astute clinician needs to understand how systemic disease can affect the CBC to direct further diagnostic investigations. This article focuses on the 2 most common acquired anemias including iron deficiency and anemia of inflammation as well as disseminated intravascular coagulation.

Abstract
The range of exposure rates to the steroidal estrogens estrone (E1), beta-estradiol (E2), estriol (E3), and ethinyl estradiol (EE2) in the aquatic environment was investigated by modeling estrogen introduction via municipal wastewater from sewage plants across the US. Model predictions were compared to published measured concentrations. Predictions were congruent with most of the measurements, but a few measurements of E2 and EE2 exceed those that would be expected from the model, despite very conservative model assumptions of no degradation or in-stream dilution. Although some extreme measurements for EE2 may reflect analytical artifacts, remaining data suggest concentrations of E2 and EE2 may reach twice the 99th percentile predicted from the model. The model and bulk of the measurement data both suggest that cumulative exposure rates to humans are consistently low relative to effect levels, but also suggest that fish exposures to E1, E2, and EE2 sometimes substantially exceed chronic no-effect levels.

Abstract
In the last decades several studies tested the hypothesis that at early development stages certain foods or nutrients, in specific amounts, fed during limited sensitive periods, may determine an endocrine metabolic asset leading to clinical alterations that take place decades later (early nutritional programming of long term health). Evidence is mounting for programming effects of infant feeding. Observational studies indicate that breast feeding, relative to formula feeding, reduces the risk for obesity at school age by about 20% even after adjustment for biological and sociodemographic confounders. Moreover, breastfeeding is constantly associated with increased neurodevelopmental scores up to early adulthood, while its outcome in terms of delayed decay of brain function is still unknown. Besides the environment surrounding breastfeeding, specific nutrients within human milk may play a direct role. With the introduction of solids the major changes in diet are represented by the sudden decrease of fat intake from 50 to 30% of total energy. A protein excess, commonly found throughout all European Countries, has been associated to a higher risk of adiposity in early childhood, as confirmed by first reports from a large European trial. The amount of fat does not seem to be associated with later adiposity, while its quality may affect blood lipoproteins, blood pressure and neurodevelopmental performance. Early intake of dietary fibers might also have beneficial effects. Epidemiologic data show that episodes of rapid growth (growth acceleration hypothesis), whichever the dietary habits, are associated with later unfavorable health conditions and should be prevented.

Iron status of one-year-olds and association with breast milk, cow's milk or formula in late infancy. Eur J Nutr 2012; 52:1661-8.

Abstract
PURPOSE Studies on iron status in infancy and early childhood have shown contradicting results concerning prolonged breast-feeding and cow's milk intake. The aim of the present study was to investigate associations between iron status among one-year-olds and feeding, with focus on the type of milk. METHODS Randomly selected healthy infants were prospectively investigated until 1 year of age in two cohorts born 1995-1996 (n = 114) and 2005 (n = 140). Information on birth data, feeding and growth until 12 months and iron status at 12 months was collected. Data from the two cohorts were pooled and the infants categorized into three groups according to their predominant milk consumption at 9 months of age, that is, breast milk, cow's milk or follow-on formula. RESULTS The prevalence of iron deficiency was highest in the cow's milk group and lowest in the follow-on formula group. According to a linear model, adjusted for gender, birth weight and exclusive breast-feeding duration, cow's milk consumption was negatively associated with serum ferritin (SF) and formula positively, but breast milk not. Predicted SF (μg/l) = 11.652(intercept) - 5.362(boy) + 0.005 × birth weight (g) + 2.826(exclusively breastfed ≥ 4 months) + 0.027 × formula (ml) - 0.022 × cow's milk (ml) + 0.005 × breast milk (ml). Correction for other dietary factors did not change these results. CONCLUSION In this pooled analysis, cow's milk intake in late infancy associated negatively, and follow-on formula positively, with iron status. Prolonged partial breast-feeding does not seem to be of importance for iron status. Fortified food seems to improve iron status in late infancy.

Abstract
AIMS Compared to exclusive breastfeeding, the introduction of solids leads to a reduction of dietary fats. We explore the hypothesis that dietary fats consumed in the 6-24-month period might have later effects on non-communicable disorders and health. DATA SYNTHESIS We have considered studies on dietary fats as substrate for oxidation and energy production, effects on adiposity, blood lipoprotein levels and features of the metabolic syndrome, and the possible influences on brain development and function. Fat oxidation, despite a high initial dietary supply, is greatly suppressed and only gradually increases after birth. There is no evidence of any convincing association between fat intake during the 6-24-month period and later indices of adiposity. Fat quality may affect the blood lipoprotein picture at short-term through the first 12 months of life. In a large Finnish trial, a moderately restricted fat diet started at 7 months, with an increased unsaturated/saturated fat ratio, has shown favourable effects on serum cholesterol values, indices of insulin resistance and endothelial function especially in boys, and had no negative effects until the age of 18 years. The dietary supply of docosahexaenoic acid might affect brain development as well as some features of the metabolic syndrome. CONCLUSIONS In the 6-24-month period, the amount of fat intake does not show associations with later health conditions, and relatively high-fat diets do not seem to be harmful. Fat quality may have later effects on chronic-degenerative processes that need to be explored more in depth.

Abstract
Prostate cancer (PCa) is dependent on androgen receptor signaling and aberrations of the PI3K-Akt-mTORC1 pathway mediating excessive and sustained growth signaling. The nutrient-sensitive kinase mTORC1 is upregulated in nearly 100% of advanced human PCas. Oncogenic mTORC1 signaling activates key subsets of mRNAs that cooperate in distinct steps of PCa initiation and progression. Epidemiological evidence points to increased dairy protein consumption as a major dietary risk factor for the development of PCa. mTORC1 is a master regulator of protein synthesis, lipid synthesis and autophagy pathways that couple nutrient sensing to cell growth and cancer. This review provides evidence that PCa initiation and progression are promoted by cow´s milk, but not human milk, stimulation of mTORC1 signaling. Mammalian milk is presented as an endocrine signaling system, which activates mTORC1, promotes cell growth and proliferation and suppresses autophagy. Naturally, milk-mediated mTORC1 signaling is restricted only to the postnatal growth phase of mammals. However, persistent consumption of cow´s milk proteins in humans provide highly insulinotropic branched-chain amino acids (BCAAs) provided by milk´s fast hydrolysable whey proteins, which elevate postprandial plasma insulin levels, and increase hepatic IGF-1 plasma concentrations by casein-derived amino acids. BCAAs, insulin and IGF-1 are pivotal activating signals of mTORC1. Increased cow´s milk protein-mediated mTORC1 signaling along with constant exposure to commercial cow´s milk estrogens derived from pregnant cows may explain the observed association between high dairy consumption and increased risk of PCa in Westernized societies. As well-balanced mTORC1-signaling plays an important role in appropriate prostate morphogenesis and differentiation, exaggerated mTORC1-signaling by high cow´s milk consumption predominantly during critical growth phases of prostate development and differentiation may exert long-term adverse effects on prostate health. Attenuation of mTORC1 signaling by contemporary Paleolithic diets and restriction of dairy protein intake, especially during mTORC1-dependent phases of prostate development and differentiation, may offer protection from the most common dairy-promoted cancer in men of Western societies.
