A new perspective on meals as part of an Optimized Mixed Diet for children and adolescents

$\bf Objectives:$ 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. $\bf Methods:$ 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. $\bf Results:$ 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. $\textbf {Discussion and conclusion:}$ 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

Erucic acid exposure during the first year of life

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

Adherence to recommendations for nutrient supplementation related to pregnancy in Germany

Supplementation of certain micronutrients is recommended to ensure their adequate supply during pregnancy and lactation. In Germany, this applies particularly to folic acid and iodine. There is no nationwide data on adherence to the supplementation guidelines. The aim of this cross-sectional study was to determine the prevalence and predictors of the recommended supplementation of both folic acid and iodine in mothers of a nationwide birth cohort. Data on supplementation, before, during, and shortly after pregnancy, were collected retrospectively 14 days postpartum in a sample of 962 mother–infant pairs participating in the second nationwide study on breastfeeding and infant nutrition in Germany, called "SuSe II" (2017–2019). Folic acid and iodine supplementation were classified as recommended according to the German guidelines if supplementation was provided for both essential periods: for folic acid before and during pregnancy and for iodine during pregnancy and lactation. Univariable tests and multivariable logistic regression analysis were performed. The vast majority of mothers did not adhere to the recommendations, with only 36.2% supplementing folic acid and 31.9% supplementing iodine during the recommended periods, and only 15.2% adhering to the recommendations for both nutrients. Main predictors of adherence to recommendations of both nutrients were lifestyle attributes and nutrition-related intentions like previous breastfeeding experience and breastfeeding intentions, but not common sociodemographic characteristics. The data suggest widespread dissemination of the time-specific recommendations covering the entire period from preconception to lactation that could help to sensitize women and healthcare providers

The role of breastfeeding promotion in German hospitals for exclusive breastfeeding duration

Breastfeeding promotion and support in hospitals is expected to have a positive impact on maternal breastfeeding outcomes. The objective of this study is to examine the association between breastfeeding promotion in maternity hospitals in Germany and exclusive breastfeeding (EBF) rates during the first 4 months. Thus, a nationwide cross-sectional web-based survey of breastfeeding promotion was conducted in 103 hospitals. Mother–infant pairs ($\it n$ = 962) were recruited at these hospitals for a prospective web-based survey of breastfeeding status at five-time points, that is, during a hospital stay, at discharge as well as after 0.5, 2, and 4 months. The hospital analysis was based on the "10 Steps to Successful Breastfeeding" of the World Health Organization and the United Nations Children's Fund, adapted for Germany. Their degree of implementation was stratified by a breastfeeding promotion index (BPI) as low ($\leq$5 steps), medium (6–8 steps), and high ($\geq$9 steps). The association between the BPI and the odds of EBF at each of the five-time points was estimated by multivariable regression models, adjusting for various maternal factors. At all time points, the proportion of EBF among mothers from high BPI hospitals exceeded the proportion of those from medium or low BPI hospitals. A high BPI was associated with higher odds of EBF during the hospital stay and at discharge, while maternal factors for EBF such as breastfeeding experience and no early use of a pacifier persisted beyond. The high commitment of hospitals and tailored support of mothers is essential for EBF

Unfavorable behaviors in children run in packs!

Children's cognitive performance can be influenced by behaviors such as eating breakfast in the morning. The aim of this analysis was to investigate the mediating effects of breakfast behavior and other lifestyle habits on eye-hand coordination and attention. In a secondary analysis of the CogniDROP study, children from the 5th and 6th grade of a comprehensive school in Germany ($\it n$ = 223) performed a simple computerized Visual Attention Task and answered a questionnaire about behavioral patterns, i.e., skipping breakfast on a school day, frequency of physical activity (PA) outside school, and nighttime sleep. An association matrix was constructed to show the relationship between the variables. Almost 11% of children left home in the morning without breakfast, more than 9.5% of children reported poor sleep quality, 24.9% slept less than the recommended 9 h, and girls were insufficiently physically active. Sleep duration, bedtime, and PA correlated with skipping breakfast. Better sleep quality was positively related to reaction time in the Visual Attention Task. Overall, the data suggest that unfavorable behaviors in children tend to run in packs, just as skipping breakfast in the morning seems to be associated with other unfavorable habits, which impairs children’s eye-hand coordination and attention

Water consumption during a school day and children's short-term cognitive performance

There is still little research examining the relationship between water consumption in school and specific cognitive performance. The aim of this cluster-randomized intervention CogniDROP trial was to investigate the short-term effects of drinking water during the morning on executive functions. The participants were from the $5^{th}$ and $6^{th}$ grade of a comprehensive school in Germany (14 classes, $\it n$ = 250, 61.6% boys). The classes were randomly divided into an intervention group (an education on healthy drinking behavior and a promotion of water consumption) and a control group. A battery of computerized tasks (Switch Task, 2-Back Task, Corsi Block-Tapping Task and Flanker Task) was used to test executive functions. Urine color and thirst were evaluated to check the hydration level. Physical activity over the past 24 h was measured using GT3X ActiGraph. A non-linear relationship was observed between the amount of drinking water and executive performance. Consuming water up to 1000 mL (or up to 50% of Total Water Intake) had benefits during memory tasks. Urine color and number of steps on the study day correlated with water consumed. The results suggest that a water-friendly environment supports school-aged children in adequate water intake resulting in better cognitive performance, especially short-term memory
