RESUMO
High dietary phosphorus intake (P-In) and high acid loads may adversely affect kidney function. In animal models, excessive phosphorus intake causes renal injury, which, in humans, is also inducible by chronic metabolic acidosis. We thus examined whether habitually high P-In and endogenous acid production during childhood and adolescence may be early indicators of incipient renal inflammatory processes later in adulthood. P-In and acid-base status were longitudinally and exclusively determined by biomarker-based assessment in 277 healthy children, utilizing phosphate and net acid excretion (NAE) measurements in 24 h urine samples repeatedly collected between the ages of 3 and 17 years. Standard deviation scores (by sex and age) were calculated for anthropometric data and for the urinary biomarkers available within age range 3-17 years. Multivariable linear regression was used to analyze the relations of phosphate excretion and NAE with the adulthood outcome circulating interleukin-18 (IL-18), a marker of inflammation and kidney dysfunction. After adjusting for growth- and adulthood-related covariates and pro-inflammatory biomarkers to rule out confounding by non-renal inflammatory processes, regression models revealed a significant positive relationship of long-term NAE (p = 0.01), but not of long-term phosphate excretion with adult serum IL-18. Similar significant positive regression results were obtained after replacing NAE with 24 h urinary ammonium excretion as the exposition variable. Our results suggest that even moderate elevations in renal ammonia production, as caused by habitually higher acid loading during growth, may affect the intrarenal pro-inflammatory system in the long-term, known to be boosted by acidosis-induced raised ammoniagenesis.

OBJECTIVE: As global warming intensifies, residents of temperate regions will also face heat waves in the near future. Food habits are one component in addressing the global challenge of climate change. However, water, the most important food for humans, has not been adequately addressed. DESIGN: For this commentary, on the one hand, publications on the increasing heat stress of children were consulted. On the other hand, publications on the special demands of children's temperature regulation in hot environments on fluid balance were analysed. SETTING: The situation of young children in care facilities on days with heat stress is presented as a scenario. In this way, the effects of climatic changes on fluid balance can be estimated and measures to reduce heat stress and stabilise the fluid balance of children can be developed. PARTICIPANTS: For this analysis, first, infants will be considered in order to identify their specific fluid needs. Second, the possibilities for caregivers to improve fluid intake and train appropriate drinking habits already in infancy will be highlighted. RESULTS: Climate change should be included in recommendations on hydration for children. The need to adapt drinking habits requires educational approaches to weather and water - starting in early childhood care. CONCLUSIONS: In the face of rapid climate change, countries must act now by protecting, preparing and prioritising the high-risk group of children. Particular focus should be placed on supporting adequate hydration.

A lower 24-h urine pH (24h-pH), i.e., a higher renal excretion of free protons, at a given acid load to the body, denotes a reduction in the kidney's capacity for net acid excretion (NAE). There is increasing evidence, not only for patients with type 2 diabetes but also for healthy individuals, that higher body fatness or waist circumference (WC) has a negative impact on renal function to excrete acids (NAE). We hypothesized that adiposity-related inflammation molecules might mediate this relation between adiposity and renal acid excretion function. Twelve biomarkers of inflammation were measured in fasting blood samples from 162 adult participants (18-25 yr old) of the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study who had undergone anthropometric measurements and collected 24-h urine samples. Both Baron and Kenny's (B&K's) steps to test mediation and causal mediation analysis were conducted to examine the potential mediatory roles of biomarkers of inflammation in the WC-24-h pH relationship after strictly controlling for laboratory-measured NAE. In B&K's mediation analysis, leptin, soluble intercellular adhesion molecule 1 (sICAM-1), and adiponectin significantly associated with the outcome 24-h pH and attenuated the WC-pH relation. In agreement herewith, causal mediation analysis estimated the "natural indirect effects" of WC on 24-h pH via leptin (P = 0.01) and adiponectin (P = 0.03) to be significant, with a trend for sICAM-1 (P = 0.09). The calculated proportions mediated by leptin, adiponectin, and sICAM-1 were 64%, 23%, and 12%, respectively. Both mediation analyses identified an inflammatory cytokine (leptin) and an anti-inflammatory cytokine (adiponectin) along with sICAM-1 as being potentially involved in mediating adiposity-related influences on renal acid excretion capacity.

OBJECTIVES: European dietary regulations affect national dietary guidelines for child nutrition. The update of the German Dietary Scheme for the first year of life is used to examine the translation of European nutrient references into food-based guidelines while maintaining traditional habits. METHODS: Within the Dietary Scheme, intake of energy and nutrients was calculated in the complementary feeding period for each of the 3 daily recommended complementary meals (a vegetable-potato-meat meal, a milk-cereal meal, a cereal-fruit meal) in addition to the daily liquid-milk servings (breast milk or follow-on formula). Pureed-home-made complementary meals were assumed. The adequacy of nutrient intake was evaluated by comparison with the European Food Safety Authority (EFSA) Dietary Reference Values. Macronutrient content of meals was compared to the European complementary food directive. RESULTS: Daily intake of most nutrients following the scheme was well in line with EFSA values, whereas the commonly 'critical' nutrients iron and iodine remained far below EFSA values. Substituting breast milk or whole cow's milk with follow-on formula had only a small impact on nutrient supply. Although the different nutrient profiles of meals were not fully in line with European regulations, they add up to an overall balanced daily diet. CONCLUSIONS: Taken together, European dietary reference values for energy and nutrients can mostly be met by the modular system of the Dietary Scheme as a total diet concept for infant nutrition in Germany. The different proposed meals generally agree with EU regulations for complementary food.

PURPOSE: Considering the low content in breast milk breastfed infants might be at particular risk for depleted iron stores after the first months of life. This study evaluates the association of the mode of milk feeding and the timing of complementary food (CF) introduction with parameters of iron status in term healthy infants in Germany. METHODS: In this secondary analysis of a randomized controlled trial, parents recorded all foods consumed by their infants from the age of 8 weeks onwards. Mothers were advised on the German food-based dietary guidelines for infants. Accordingly, CF was introduced between the fifth and seventh month of age. Blood samples were taken at 4 and at 10 months of age for analyses of iron status parameters. Iron depletion was defined as serum ferritin <12 ng/mL. RESULTS: The iron intake was lower in breastfed infants (n = 50) than in formula fed (n = 23) with decreasing differences during the course of infancy. At 10 months of age, most iron parameters were not associated with the mode of milk feeding or the timing of CF introduction. At this age, the iron depletion prevalence was >34% without general differences according to the mode of milk feeding or the timing of CF introduction. CONCLUSION: The high prevalence of depleted iron stores observed in both breastfed and formula-fed infants illustrates the need for further studies to improve our understanding of the optimal iron intake and sensitive parameters of iron status in infancy.

PURPOSE: Introduction of complementary food usually leads to decreasing intakes of long-chain n-3 polyunsaturated fatty acids (n-3 LC-PUFA), compared to full breastfeeding. In the randomised controlled PINGU intervention trial, we tested the effects of complementary foods with different contents of alpha-linolenic acid (ALA) and docosahexaenoic acid (DHA) on term infant LC-PUFA status. METHODS: Healthy infants born at term were randomised to receive from the introduction of complementary feeding at the age of 4 to 6 months until age of 10 months ready-made complementary meals either with ALA-rich rapeseed oil (intervention group (IG)-R), with salmon twice weekly to provide preformed DHA (IG-F), or with linoleic acid-rich corn oil (control group, CG). Fatty acid composition was assessed in erythrocyte (RBC) and plasma glycerophospholipids. RESULTS: Complete data of fatty acids in RBC (plasma) were available from 158 (155) infants. After intervention, infants assigned to IG-F showed higher RBC and plasma percentages of eicosapentaenoic acid (EPA), DHA, and total n-3 LC-PUFA than CG (each p < 0.001). In IG-R, levels of ALA and the ratio of ALA to LA in plasma and RBC (all p < 0.0001) as well as RBC-EPA (p < 0.0001) were higher than in CG, while DHA levels did not differ between IG-R and CG. CONCLUSIONS: Regular fish consumption during complementary feeding enhances infant EPA and DHA status. The usage of rapeseed oil in small amounts concordant with EU-law for commercial meals enhances endogenic EPA-synthesis, but does not affect DHA status. Provision of oily fish with complementary feeds is advisable to prevent a decline of DHA status.

PURPOSE: German guidelines recommend breast milk as ideal for infant's nutrition, supporting exclusive breastfeeding for at least 4 months. Moreover, in mothers with insufficient fish intake, DHA status may be improved by supplementation during pregnancy and lactation. However, little is known on current rates of breastfeeding and DHA supplementation in Germany. The objective of this study was to analyse frequencies and demographic determinants of breastfeeding and DHA supplementation in Germany. METHODS: Data derived from a nationwide consumer survey of 986 mothers with children between 5 and 36 months of age in Germany. RESULTS: 78.3% reported that they ever breastfed their children, and 55.6% of the mothers exclusively breastfed for at least 4 months. Mothers who did not breastfeed were less likely to be informed by their paediatrician or midwife and were more often not informed at all; 27.8% of mothers used DHA supplements during pregnancy, 16.8% postnatal. DHA supplementation was more common in women with a high versus a low fish intake. The social status was the major determinant of breastfeeding initiation and exclusivity and also DHA supplementation. CONCLUSION: Breastfeeding initiation and duration of exclusive breastfeeding in Germany need to be improved. Professional counselling and support, with a focus on mothers from lower social classes, appears necessary to increase current rates of breastfeeding initiation, duration, and exclusiveness, but also to ensure a sufficient supply with DHA in pregnant and lactating women, particularly in women with low fish consumption.

Early infant feeding and swallowing are complex motor processes involving numerous muscles in coordination, e.g. the orofacial muscles as well as the muscles of the pharynx, larynx and esophagus. The newborn's reflexive drinking develops into the ability to ingest pureed complementary food as infancy progresses. Finally, in the last part of the first year of life, a differentiated eating, chewing and swallowing process develops allowing the voluntary intake of different foods of the family diet. The dietary schedule for the first year of life, which describes the recommended nutrition of infants in Germany, corresponds to these milestones in eating development. Disturbances in gross motor development, sensory processing issues, and organic and behavioral problems are known to interfere with the development of eating skills. Swallowing disorders (dysphagia) in children can have a detrimental effect on food intake and pose a serious risk to growth and development. Their prevention treatment requires a multidisciplinary approach with the aim of enabling the child to eat independently in the long term.

INTRODUCTION: Childhood asthma is a highly prevalent chronic disease. A failure to implement patient education programmes may result in increased morbidity, despite the availability of distinct diagnostic and therapeutic approaches. Patients with lower socioeconomic status (SES) tend to have a higher asthma prevalence. Moreover, the progression of asthma is significantly influenced by factors such as health literacy and the children's specific knowledge about the condition. With this trial, the primary objective is to evaluate whether asthma education enhances specific disease understanding in children with asthma (primary outcome). Secondary objectives include evaluating training effects on health literacy, retention rates of information, 'Children Asthma Control Test' (C-ACT) score, frequency of emergency room and physician visits (secondary outcomes) and whether SES influences training effects. METHODS AND ANALYSIS: To address the research objectives, this study comprises two projects. The first subproject will investigate the influence of asthma training on the development of disease understanding and health literacy. The second subproject will analyse the influence of SES on the outcome of children participating in asthma training. This research is designed as a comparative, non-randomised study involving two paediatric groups between the ages of ≥7 and < 14 years. After being diagnosed with asthma, the intervention group undergoes standardised psychoeducational asthma training at a certified centre associated with paediatricians in private practice in Germany, following the recommendations of the 'Arbeitsgruppe Asthmaschulung im Kindes- und Jugendalter e.V.', a national association aiming to establish uniform and guideline-based standards for patient education in children and adolescents. The comparison group receives a significantly shorter period of education and instruction on the usage of asthma medication at outpatient clinics. Data will be collected from patients and their parents at three specific survey time points, based on standardised tools.To describe mean differences between the intervention and control group over time (subproject 1), a repeated-measures analysis of variance (ANOVA) will be conducted. In subproject 2, multivariate linear regression analysis will be used to analyse the variables determining the changes in specific disease understanding and health literacy, including SES. The sample size calculation is based on a mixed ANOVA model with two groups and two measurements resulting in a total of 126 participants. ETHICS AND DISSEMINATION: All protocols and a positive ethics approval were obtained from the Witten/Herdecke University, Germany (S-159, 2023; application submission: 24 June 2023, final vote: 10 July 2023). Furthermore, the study was registered at the German Clinical Trials Register (DRKS), DRKS00032423. The application submission was on 3 August 2023, and the final approval was on 4 August 2023. The results will be disseminated among experts and participants and will be published in peer-reviewed, international journal with open access. TRIAL REGISTRATION NUMBER: DRKS00032423.

Nonalcoholic fatty liver disease (NAFLD), frequently already present in young subjects, has been linked to reduced growth hormone levels and signaling. Similar hormonal changes occur during metabolic acidosis (MA), which may thus contribute to an increased NAFLD risk. Because subclinical MA can be diet induced, we aimed to examine whether a higher diet-dependent acid load during adolescence is prospectively associated with several currently used NAFLD surrogates in young adulthood. Dietary acidity during adolescence (boys:10-15 y, girls: 9-14 y) was calculated as potential renal acid load (PRAL) from at least three 3-d weighed dietary records according to a published algorithm considering dietary protein and minerals in 145 healthy participants. Routine measurements derived from blood analysis and anthropometric data in participants' young adulthood (18-25 y) were used to determine the NAFLD surrogates alanine-aminotransferase (ALT), hepatic steatosis index (HSI), and fatty liver index (FLI). Sex-stratified linear regression models, adjusted for dietary fiber, saturated fat, protein, and adolescent BMI SD scores, were run with PRAL as the independent variable. Dietary PRAL during puberty was positively associated with ALT (P = 0.02), HSI (P = 0.002), and FLI (P = 0.005) in adult females but not males. Females with an adolescent dietary acid load in the highest tertile had 3.5, 4.4, and 4.5 higher values of ALT, HSI, and FLI as adults, respectively, compared to females with the lowest PRAL. The present findings suggest that higher dietary acidity in adolescence may be prospectively associated with hepatic lipid accumulation in females. Whether this relationship is due to the higher proton load or rather represents an unhealthy dietary pattern requires further investigation.

Objectives: To show by the example of the Optimized Mixed Diet (OMD) for children and adolescents in Germany, how the different food and nutrient profiles of the traditional daily meals complement each other to achieve daily nutrient intakes that meet the Dietary References V. Methods: The 7-day menu plan of the OMD with the usual 5 daily meals in Germany was used. The total nutrient intake from all meals was compared with the nutrient references. Then the composition of the meals was optimized. Results: Although the cooked meal (lunch) provides only 25% of the daily energy intake, it is relatively rich (>25% of the daily intake) in most vitamins and minerals, which distinguishes it from the other meals. The cold main meals (breakfast, dinner) are rich in calcium and vitamin B2, due to the preferential use of milk in these meals. The two snacks each provide 12.5% of the daily energy intake. Discussion and conclusion: People eat foods but not nutrients and they eat foods as meals; this holds especially true for children and adolescents. A well-calculated menu plan can assure the nutrient adequacy of an OMD where the different food and nutrient profiles of the meals complement each other in a modular system. Guidelines for meals could facilitate flexible coordination of family meals and meals in childcare centers and schools. Different meal types set varied stimulus patterns at different levels (neurocognition, emotion, digestion), which may open up long-term health benefits.
RESUMO
Recently, the European Food Safety Authority (EFSA) issued a tolerable daily intake (TDI) for erucic acid, which is mainly found in rapeseed oil. Infants may be exposed to erucic acid from rapeseed oil indirectly through maternal consumption via breastmilk or the fat component in formula, and directly as a part of complementary feeding (CF). To check the safety of infant nutrition, scenarios for erucic acid exposure were calculated based on the daily food amounts of the German dietary guidelines. Information on erucic acid concentrations in foods was obtained from European studies for breastmilk, from EFSA samples for formula powder, and from a representative analysis of rapeseed oil samples in the German retail market. 6 scenarios were calculated for the early milk feeding phase (4 formula feeding, 2 breastfeeding) and 8 scenarios for the later CF phase (5 CF +formula feeding, 3 CF +breastfeeding). Out of the 14 scenarios, only 3 resulted in exposures that were definitively below the TDI (range 4.4.-6.0 mg/kg bodyweight; BW). Assuming either high consumption or high concentration led to high exceedances (range 7.5-26.2 mg/kg BW), especially in case of the new EU limits for formula or vegetable oils (33.6 and 43.2 mg/kg BW, respectively). In our scenarios, high erucic acid exposures occurred during a particularly sensitive developmental period. To definitively weigh the potential risks from erucic acid in infants against nutritional benefits of the dietary recommendations, reliable, timely data on erucic acid in breast milk and formula are needed, similar to those from rapeseed oil in Germany.
RESUMO
Human milk contains more than 150 different oligosaccharides, which together are among to the quantitatively predominant solid components of breast milk. The oligosaccharide content and composition of human milk show large inter-individual differences. Oligosaccharide content is mostly influenced by genetic variants of the mother's secretor status. Oligosaccharides in human milk are utilized by infants' intestinal bacteria, affecting bacterial composition and metabolic activity. Maternal secretor status, and respective differing fucosylated oligosaccharide content, has been associated both with reduced and increased risk of infection in different populations of breastfed infants, possibly due to environmental conditions and the infant's genotype. There are no safety concerns regarding the addition of previously approved oligosaccharides to infant formula; however, no firm conclusions can be drawn about clinically relevant benefits either. Therefore, infant formulas with synthetic oligosaccharide additives are currently not preferentially recommended over infant formulas without such additives. We consider the use of terms such as "human milk oligosaccharides" and corresponding abbreviations such as "HMO" in any advertising of infant formula to be an inappropriate idealization of infant formula. Manufacturers should stop this practice, and such marketing practices should be prevented by responsible supervisory authorities. Pediatricians should inform families that infant formulas supplemented with synthetic oligosaccharides do not resemble the complex oligosaccharide composition of human milk.
RESUMO
BACKGROUND AND OBJECTIVE: The use of the impulse oscillometry system (IOS) allows differentiated lung function testing with a minimum of cooperation at normal tidal breathing. The aim of this cross-sectional study was to assess the association of body mass (overweight and obese) with oscillometric parameters in preschool children. METHODS: A preschool medical check of 518 children (age 6.01 ± 0.25 years) included IOS recordings of airway resistance and lung reactance (MasterScreen IOS, CareFusion, Höchberg, Germany). Measured values of respiratory resistance (R5) and reactance (X5) at 5 Hz were correlated with BMI. In addition, data were compared with recently published reference equations. RESULTS: In this young age group of 241 boys and 277 girls there was no significant association between oscillometric parameters and BMI. When compared with current IOS reference values of healthy subjects the relationship of R5 (109 ± 25%) and X5 (105.5 ± 35%) suggested mildly elevated peripheral resistance in this unselected group of preschool children. CONCLUSIONS: IOS is ideally suited to obtain measurements of respiratory function in preschool children. At the age of 6 years, standard oscillometric values do not indicate impaired respiratory function associated with increased BMI.

RESUMO
Infancy may represent a sensitive window for establishing food preferences that could affect the individual's long-term potential to establish healthy eating patterns. Our study was based on the hypothesis that preserving the natural flavor of the ingredients of commercially prepared complementary foods would increase the acceptance of new foods, especially vegetables. Frozen vegetable-based meals for infants were developed to preserve the natural taste of the ingredients better than sterilization of meals in jars. In a 3-month randomized, controlled intervention study, 51 infants were fed either frozen menus (intervention group) or commercial sterilized meals in jars (control group) on at least 5 days per week. Then the acceptability of a known vegetable-based puree was tested in comparison to an unknown puree, measuring the quantities consumed and also the mother's assessment of the infants' liking. In conclusion, the results of this study clearly indicated that infants fed vegetable-based frozen meals for 3 months accepted a new vegetable better than infants fed sterilized commercial meals in jars.

In a pilot study, we wanted to influence the food selection of employees in a pediatric clinic bistro aiming to increase the sale of "healthy" grain buns (number and proportion of all sold buns). During basic assessment, the mean weekly sale of grain buns was 98 (52.3%) and in the second week of highlighting them on a green napkin under a transparent hood (intervention 1) reached 124 (54.6%). However, just when starting intervention 2 (position in front of the display), the bistro was closed due to the Coronavirus pandemic. Thus, necessary public health measures stopped our interventional public health experiment.

BACKGROUND: To investigate whether a low meat content of complementary food as accepted by EU law increases the risk of well-nourished infants to develop iron deficiency during the complementary feeding period. METHODS: Term born, healthy infants were randomized into a 'High Meat' Group (HM, n = 48) receiving commercial baby jars with a meat content of 12% by weight (according to pediatric guidelines), and a 'Low Meat' Group (LM, n = 49) receiving meals as marketed (meat 8% by weight, the lowest level of EU law). Intervention was from 4 to 10 months of age. Dietary intake was recorded continuously, repeated blood samples were collected. RESULTS: Estimated intake of bioavailable iron conformed to reference requirements. In the primary analysis of the total sample, iron status was adequate before (4 months), during (7 months), and after (10 months) the intervention. A secondary analysis in the subgroup of infants fully breast-fed for 4-6 months demonstrated an increased risk of low Hb values with 10 months of age in the LM group. INTERPRETATION: Present day low meat content of complementary food does not significantly impair iron status in well-nourished infants but may increase the risk of developing marginal iron status in older infants after fully breast-feeding for 4-6 months, i.e., in the subgroup of infants with the lowest habitual iron intake.

BACKGROUND: The breastfed infant is usually used as standard for formula feeding, also regarding long-chain polyunsaturated fatty acids (LC-PUFA). Here, plasma fatty acid concentrations in formula fed infants and the effects of LC-PUFA supplementation were investigated under real-life conditions. METHOD: Term healthy infants being fully milk fed until the age of 4 months were categorized as breast milk "BM" (n = 73) if consuming >95% of energy from breast milk or formula (F) if consuming >95% of energy from formula subdivided into formula without (F-) (n = 15) and with LC-PUFA supplementation (F+) (n = 15). Formula as marketed was chosen by the parents. Dietary fatty acids (FA) intake was calculated from continuous dietary records from 2 months of age onwards. Total plasma FA were analyzed at the age of 4 months with docosahexaenoic acid (DHA) as primary outcome. RESULTS: Dietary ratios of the polyunsaturated fatty acids (PUFA; linoleic acid/alpha-linolenic acid) were smaller in both F groups than in the BM group. Plasma DHA as % of total FA was similar in BM and F(+) but higher in BM in absolute amounts (mg/L). Plasma DHA as % of total FA in F(-) was higher than what might be supposed on the basis of dietary intake. CONCLUSION: Infants consuming present-day LC-PUFA-supplemented formula achieved plasma LC-PUFA concentrations similar to breastfed infants. In infants consuming non-LC-PUFA-supplemented formula, the favorable PUFA pattern of the formula may have supported n-3 LC-PUFA biosynthesis.
