Elemental composition of toxic and essential elements in rice-based baby foods from the United States and other countries: A probabilistic risk analysis.

Consumption of rice-based foods provides essential nutrients required for infants and toddlers' growth. However, they could contain toxic and excess essential elements that may affect human health. The study aims to determine the composition of rice-based baby foods in the USA and outside and conduct a multiple-life stages probabilistic exposure and risk assessment of toxic and essential elements in children. Elemental concentrations were measured using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) in thirty-three rice-based baby foods. This includes 2 infant formulas, 11 rice baby cereals, and 20 rice snacks produced primarily in the United States, China, and other countries. A probabilistic risk assessment was conducted to assess risks of adverse health effects. Results showed that infant formula had higher median concentrations of selenium (Se), copper (Cu), zinc (Zn), sodium (Na), magnesium (Mg), calcium (Ca), and potassium (K) compared to rice baby cereal and rice snacks. On the contrary, rice snacks had the highest median concentration of Arsenic (As) (127 µg/kg) while rice baby cereals showed the highest median concentration of Cd (7 µg/kg). A higher lifetime estimated daily intake was observed for samples manufactured in the USA compared to those from China and other countries. Hazard quotient (HQ < 1) values were suggestive of minimal adverse health effects. However, lifetime carcinogenic risk analysis based on total As indicated an unacceptable cancer risk (>1E-04). These findings show a need for ongoing monitoring of rice-based foods consumed by infants and toddlers as supplementary and substitutes for breast milk or weaning food options. This can be useful in risk reduction and mitigation of early life exposure to improve health outcomes.

Complementary feeding practices of caregivers of infants with Down syndrome as compared to caregivers of typically developing infants.

Caregiver feeding practices during the complementary feeding period (6 months-2 years) may be particularly important for infants with Down syndrome (DS) as they are at higher risk for later health conditions (e.g., obesity, diabetes) that can be influenced by early feeding practices. However, how well caregivers of infants with DS are meeting infant feeding evidence-based practices is relatively unknown. Caregivers of infants with DS (N = 75) and caregivers of typically developing (TD) infants (N = 66) aged 0-2 years completed an online survey about their infant feeding practices and information sources. Caregiver practices and information sources were statistically compared between groups. Results indicated that there are significant differences in the feeding practices of caregivers of infants with DS when compared to caregivers of TD infants. Caregivers of infants with DS were less likely to meet infant feeding evidence-based practices than caregivers of TD infants. Caregivers of infants with DS were also more concerned about their infant's food intake and later weight status. Some individual feeding practices also significantly differed between groups, with caregivers of infants with DS more likely to meet evidence-based practices of purchasing iron rich foods and avoiding added salt, but less likely to use responsive feeding practices than caregivers of TD infants. Caregivers of infants with DS were also less likely to receive information about how to navigate the complementary feeding period than caregivers of TD infants. Coupled with existing research, the results of the present study suggest that infant feeding evidence-based practices should be reviewed for their appropriateness for this population and additional support for caregivers of infants with DS should be implemented to help them navigate this important period.

Co-ingestion of Cereals and Legumes during Infant Complementary Feeding: Starch and Protein in vitro Digestion.

This study explores the impact of co-ingesting cereals and legumes on starch and protein during simulated infant in vitro digestion. Various legumes (chickpeas, lentils, peas) were added to cereals (durum wheat, brown rice, white maize), and their effects on starch and protein hydrolysis were analyzed. Substituting 50% of cereal with legumes increased proteins, minerals, and dietary fiber. Infant food with legumes exhibited smoother pasting properties. Legumes in cereal purées led to varying starch hydrolysis trends, with the lowest values in durum wheat with chickpea and all cereal blends with peas. Resistant starch levels exceeding 50% were found in infant food samples. Digested protein hydrolysis increased with legumes in durum wheat, except for peas. Brown rice mixtures decreased significantly compared to the control with chickpeas (61%) and peas (42%), while lentil blends increased by 46%. Legumes generally did not significantly affect starch bioavailability, even with α-amylase inhibitors. Lentil-cereal purées could enhance infant food nutritional value.

Development of a vortex-assisted switchable-hydrophilicity solvent-based liquid phase microextraction for fast and reliable extraction of Zn (II), Fe (II), Pb (II), and Cd (II) from various baby food products.

This manuscript describes the development of a novel liquid phase microextraction (LPME) method for the extraction and determination of Zn (II), Fe (II), Pb (II), and Cd (II) in various infant/baby food and supplements products. The method is based on vortex-assisted extraction combined with a switchable-hydrophilicity solvent (SHS) sample preparation. The SHS, which undergoes reversible phase changes triggered by pH change, enables selective extraction and easy phase separation. A flame atomic absorption spectroscopy was used in the final determination step. Optimization studies revealed, that the optimal pH of the sample solution (after digestion) during analytes extraction is 5.5. A l-proline is added to the sample (375 mM) to ensure the complexation of the target metal cations. After the complexation step, 750 µL of SHS - a N, N-Dimethylcyclohexylamine along with 0.9 mL of 2 M of acetic acid solution is added (hydrophilicity switch-on stage) and mixed manually to obtain a homogeneous solution. In the last stage, 0.45 mL of 10 M NaOH solution (hydrophilicity switch-off stage) is added to the sample solution and a vortex for 100 s is applied to ensure the effective extraction and separation of the complex containing the analytes. At this stage, a cloudy solution is immediately obtained. Finally, the effective phase separation is obtained at the centrifugation step (4000 rpm for 2 mins). The method limit of detection was as 0.03, 0.009, 0.6, and 0.2 ng/L for Zn (II), Fe (II), Cd (II), and Pb (II) respectively with RSD% below 2.0 %. The analysis of certified reference materials and real samples proved the full applicability of the method for routine analysis, contributing to the field of heavy metal analysis and ensuring the safety of baby products. According to the AGREE methodology, this method can be named as green analytical chemistry method with a score of 0.77.

Contribution of Infant Food Pouches and Other Commercial Infant Foods to the Diets of Infants: A Cross-sectional Study.

BACKGROUND: Although considerable concern has been expressed about the nutritional implications of infant food pouches, how they impact infant diet has not been examined. OBJECTIVES: The objective of this study was to determine the contribution of infant food pouches specifically, and commercial infant foods generally, to nutrient intake from complementary foods in infants. METHODS: Two multiple-pass 24-h diet recall data were collected from 645 infants (6.0-11.9 mo) in the First Foods and Young Foods New Zealand studies. Detailed information was obtained on commercial infant food use, including pouches, and nutrient composition was calculated through recipe modeling. RESULTS: The diverse sample (46.1% female; 21.1% Maori, 14.1% Asian, and 54.6% European) was aged (SD) 8.4 (0.9) mo. More than one-quarter of households had high socioeconomic deprivation. Almost half (45.3%) of infants consumed an infant food pouch on ≥1 recall day [mean (SD), 1.3 (0.9) times/d], obtaining 218 (124) kJ of energy on each eating occasion. Comparable numbers for all commercial infant and toddler foods (CITFs) were 78.0%, contributing 2.2 (1.6) and 140 (118) kJ of energy. Infant food pouches provided 25.5% of the total energy from complementary foods in those infants who consumed pouches on the recall days but just 11% in all infants. Median percentage contribution of infant food pouches to nutrient intake from complementary foods in consumers ranged from <1% (added sugars and retinol) to >30% (carbohydrate, total sugars, fiber, vitamin A, and vitamin C). CITF contributed 21.4% of energy from complementary foods for infant consumers, with median percentage contribution ranging from 0.1% (retinol) to 40.3% (iron). CONCLUSIONS: Infant food pouches make relatively small contributions to energy intake in infants but are important sources of carbohydrates, fiber, and vitamins A, C, and B-6. Almost half of the total sugars consumed from complementary foods is provided by these pouches. This trial was registered at the Australian New Zealand Clinical Trials Registry as ACTRN12620000459921.

Estimated energy and nutrient intake in complementary feeding methods in Brazilian infants: randomized clinical trial.

Inadequate nutrient intake during complementary feeding (CF) can affect healthy infant growth and development. A randomized clinical trial was conducted to examine the energy and nutrient intake in Brazilian children randomly assigned to three distinct CF methods. Mother-infant pairs participated in the study, with mothers receiving interventions in one of three CF approaches: (A) strict Parent-Led Weaning (PLW); (B) strict Baby-Led Introduction to Solids (BLISS); and (C) a mixed method. Assessments were made at 5.5 months, nine months, and 12 months of the child's age. Food consumption was measured through 24-h dietary recalls at nine and 12 months, with intake estimates calculated using the Brazilian Food Composition Table. Means or medians of energy and nutrients were compared between groups using ANOVA with Tukey's post hoc test or the Kruskal-Wallis test. A total of 115 infants were evaluated at nine months, and 102 at 12 months. Children in the PLW, BLISS, and mixed method groups exhibited comparable dietary intakes of energy, macronutrients, and micronutrients at both nine and 12 months. Infants following PLW, BLISS, and mixed methods demonstrated similar levels of energy and nutrient intake, underscoring the effectiveness of these strategies in ensuring comparable nutrient intake during the critical phase of CF.Trial registration The trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with identifier [RBR-229scm U1111-1226-9516], [ https://ensaiosclinicos.gov.br/rg/RBR-229scm ]. The full data of the first registration was on 24/09/2019.

Food pattern modeling to inform global guidance on complementary feeding of infants.

Nutrient needs are difficult to meet during infancy due to high nutrient requirements and the small quantities of food consumed. Guidelines to support food choice decisions are critical to promoting optimal infant health, growth and development and food pattern modeling can be used to inform guideline development. We employed the Optifood modeling system to determine if unfortified complementary foods could meet 13 nutrient targets for breastfed infants (6-11 months), and to describe food patterns that met, or came as close as possible to meeting targets. We also examined the impacts of eliminating food groups, increasing starchy staple foods or adding sentinel unhealthy foods. We collated a global food list from dietary studies in 37 countries and used this list to develop nutrient values for a set of 35 food subgroups. We analyzed infant dietary intakes from studies in eight countries to inform maximum quantities and frequencies of consumption for these subgroups in weekly food patterns. We found that unfortified foods could meet targets for most infants for 12 nutrients, but not for iron. For the smallest and youngest infants, with the lowest energy intakes, there were additional deficits for minerals. Best-case food patterns that met targets or came as close as possible to meeting targets included ample amounts of diverse vegetables, diverse plant- and animal-source protein foods, small amounts of whole grain foods and dairy and no refined grains or added fats or sugar. There were nutrient deficits if animal-source foods or vegetables were eliminated or if unhealthy foods were included.

Early Introduction of Novel and Less-Studied Food Allergens in the Plant-Based Era: Considerations for US and EU Infant Formula Regulations.

Early life feeding practices may affect the long-term health of individuals, particularly in terms of the development of non-communicable diseases, such as metabolic and allergic diseases. Accumulating evidence suggests that the interplay of breastfeeding and/or formula feeding followed by the introduction of solids plays a role in the occurrence of non-communicable diseases both in the short and long term. International food allergy guidelines recommend that breastfeeding women do not need to avoid food allergens and do not recommend any infant formula for allergy prevention. Guidelines regarding solid food introduction for food allergy prevention recommend the introduction of well-cooked eggs and peanuts around 4-6 months of age, and not to delay the introduction of other food allergens. There is also an increasing trend to feed infants a plant-based or plant-forward diet and have access to infant formulas based on plant-based ingredients. The use of novel plant-based infant formulas raises a few questions reviewed in this paper: (1) Do fortified, plant-based infant formulas, compliant with US Food and Drug Administration (FDA) regulations and European Food Safety Authority (EFSA) (European) guidelines, support adequate infant growth? (2) Are plant-based infant formulas suitable for the management of cow's milk allergy? (3) Does feeding with novel, plant-based infant formulas increase the risk of food allergies to the food allergens they contain? (4) Does feeding infants plant-based food allergens in early life increase the risk of allergic and severe allergic reactions? The review of the literature indicated that (1) plant-based formulas supplemented with amino acids and micronutrients to comply with FDA regulations and EFSA guidelines, evaluated in sufficiently powered growth studies, can support adequate growth in infants; (2) currently available plant-based infant formulas are suitable for the management of CMA; (3) an early introduction and continuous intake of food allergens are more likely to prevent food allergies than to increase their risk; and (4) an early introduction of food allergens in young infants is safe.

Adherence to Infant Feeding Guidelines in the First Foods New Zealand Study.

Infant feeding guidelines provide evidence-based recommendations to support optimal infant health, growth, and development, and exploring adherence to guidelines is a useful way of assessing diet quality. The aim of this study was to determine adherence to the recently updated Ministry of Health "Healthy Eating Guidelines for New Zealand Babies and Toddlers (0-2 years old)". Data were obtained from First Foods New Zealand, a multicentre observational study of 625 infants aged 7.0-10.0 months. Caregivers completed two 24-h diet recalls and a demographic and feeding questionnaire. Nearly all caregivers (97.9%) initiated breastfeeding, 37.8% exclusively breastfed to around six months of age, and 66.2% were currently breastfeeding (mean age 8.4 months). Most caregivers met recommendations for solid food introduction, including appropriate age (75.4%), iron-rich foods (88.3%), puréed textures (80.3%), and spoon-feeding (74.1%). Infants consumed vegetables (63.2%) and fruit (53.9%) more frequently than grain foods (49.5%), milk and milk products (38.6%), and meat and protein-rich foods (31.8%). Most caregivers avoided inappropriate beverages (93.9%) and adding salt (76.5%) and sugar (90.6%). Our findings indicated that while most infants met the recommendations for the introduction of appropriate solid foods, the prevalence of exclusive breastfeeding could be improved, indicating that New Zealand families may need more support.

[Status of infant and young child feeding in China in 2016-2017].

OBJECTIVE: To describe the feeding status and related factors of infant and young child aged 6-23 months in China. METHODS: Data was from the China Nutrition and Health Surveillance among 0-17 Years Old Children and Lactating Women in 2016-2017, and 20 423 children aged 6-23 months were involved in 275 surveillance sites from 31 provinces(autonomous regions and municipalities). The introduction of solid, semi-solid or soft foods, minimum dietary diversity, minimum meal frequency were analyzed with WHO and UNICEF 2021 updated infant and young child feeding indicators. Data analyses were conducted using the complex weight based on national census from National Bureau of Statistics in 2010. Rao-Scott Chi-square was used test for statistical difference. RESULTS: The percentage of infants 6-8 months of age who consumed solid, semi-solid or soft foods was 83.2%(95%CI 80.5%-85.9%) in 2016-2017. No significant difference were observed between boys and girls; there was significant difference in different areas(Rao-Scott χ~2=30.85, P<0.01), it was 90.3% in medium and small cities, and reached 75.0% even in poor rural areas. The proportions of children aged 6-23 months meeting minimum dietary diversity(MDD) was 60.6%(95%CI 58.1%-63.1%). It was 71.1% in medium and small cities, and 50.5% in poor rural areas. Except for breast milk, the percentage of eggs(34.4%) and legumes(19.0%) consumption was low, the percentage of grains, vitamin A-rich fruits or vegetables consumption was 89.7%(95%CI 88.4%-91.1%). The percentage of consuming egg and/or flesh food was 76.4%(95%CI 74.2%-78.7%). The percentage of zero vegetables or fruits consumption was 9.1%(95%CI 7.8%-10.4%). The proportions of children aged 6-23 months meeting minimum meal frequency(MMF) was 72.4%(95%CI 70.1%-74.7%). It was over 70% in large cities, medium and small cities, general rural areas; and 60.2% in poor rural areas. The proportions of children aged 6-23 months meeting minimum acceptable diet was 43.4%(95%CI 40.7%-46.1%), it was over 50% in urban areas, and less than 40% in rural areas, 30.1% in poor rural areas. No consistent differences were observed between boys and girls for all 3 indicators(MDD, MMF and MAD), and there was significant difference in different areas and various months of age(P<0.01). CONCLUSION: There was no gender difference in the feeding status of children aged 6-23 months in China, the complementary feeding was relatively timely, and the minimum dietary diversity and meal frequency of children were relatively ideal, but the minimum acceptable diet of children in poor rural areas was poor.

The effect of baby-led weaning and traditional complementary feeding trainings on baby development.

PURPOSE: The aim of this study was to evaluate the risks of self-feeding, transition to early solid food and family meals, choking risk, anemia risk and obesity risk in 6-12-month-old infants who were introduced to complementary feeding using the traditional complementary feeding (TCF) and baby-led weaning (BLW) methods/training. DESIGN AND METHODS: Mothers of infants who had not yet transitioned to complementary feeding were included in this randomized study. The mothers of 62 infants included in the study were randomized into the intervention groups as TCF and BLW, classified according to the number of children and education level. The research was carried out according to the CONSORT-2010 guidelines after randomization and was concluded with 52 infants and their mothers. RESULTS: It was found in the study that self-feeding and transition to solid foods in infants fed with the BLW method was higher than the infants fed with the TCF method (p < 0.05). A significant increase was observed in the hemoglobin level of infants fed with the BLW method over time (p < 0.001). CONCLUSIONS: It was concluded that the BLW method did not lead to risks of obesity, anemia and iron deficiency in transition to complementary feeding. Secondary results indicated that feeding with the BLW method promoted self-feeding and early transition to solid foods and did not lead to the risk of choking. PRACTICE IMPLICATIONS: Complementary feeding with the BLW method can be safely used by both mothers, healthcare professionals and researchers. TRIAL REGISTRATION: register.

Suitability and Potential Nutrient Contribution of Underutilized Foods in Community-Based Infant Foods in Northern Ghana.

In rural Ghana, infant feeding is largely home-based or community-based yet less is known about the kinds of community-based infant foods and the ability of families to create a range of recipes for baby feeding using context-specific ingredients particularly in northern Ghana which has a high prevalence of malnutrition. In this explorative study on mothers (15-49 years; n = 46), we investigated community-based infant foods' food group composition, enrichment, nutrient contribution, and acceptability. The identified community-based infant foods were mainly made of either corn or millet porridges in northern Ghana and had three nutrients with % RNI ≥ 70. We developed 38 recipes of enriched community-based infant foods adding underutilized foods (orange-fleshed sweet potato, pawpaw, cowpea, moringa, groundnut, Bambara beans, and soya beans) to increase the number of nutrients from three to at least five and at most nine nutrients with % RNI ≥ 70 based on the recipe combinations. The enriched community-based infant food recipes provided adequate caloric amounts and modest improvements in micronutrient content for infants (6-12 months). All recipes tested were deemed appropriate and acceptable for infants by mothers. Moringa and pawpaw emerged as the lowest-cost ingredients to add among the underutilized foods. Future research is necessary to assess the effectiveness of the new recipes at promoting linear growth and improving micronutrient status during the complementary feeding period.

The big squeeze: a product content and labelling analysis of ready-to-use complementary infant food pouches in Australia.

BACKGROUND: Encouraging the early development of healthy eating habits prevents diet-related chronic disease. It is well understood that highly processed foods with high amounts of sugars, salt and fats are a risk factor for non-communicable diseases. Commercial baby foods in ready-to-use squeeze pouches emerged in the global food market around 2012. The long-term effects of this now ubiquitous packaging on the quality of infant diets, baby food consumption and marketing are unknown. This study aimed to conduct a rigorous mixed-methods audit of squeeze pouches in Australia to inform product regulation and policy. METHODS: Nutritional and marketing data were sourced from products available in Australian retailers. Analysis of nutritional content, texture and packaging labelling and serving size was conducted. Pouches were given a Nutrition Profile Index (NPI) score and compared with the Australian Infant Feeding Guidelines. Marketing text was thematically analysed and compared to existing infant nutrition policy around regulation of marketing claims. RESULTS: 276 products from 15 manufacturers were analysed, targeting infants from 4 + to 12 + months. Total sugar content ranged 0.8-17.5 g/100 g, 20% (n = 56) of products had added sugars, 17% (n = 46) had added fruit juice, 71% (n = 196) had added fruit puree. Saturated fat content ranged from 0.0 to 5.0 g/100 g, sodium 0.0-69 mg/100 g and dietary fibre 0.0-4.3 g/100 g. Only two products were nutritionally adequate according to a nutrient profiling tool. Marketing messages included ingredient premiumisation, nutrient absence claims, claims about infant development and health, good parenting, and convenience. Claims of 'no added sugar' were made for 59% of pouches, despite the addition of free sugars. CONCLUSIONS: Squeeze pouch products available in Australia are nutritionally poor, high in sugars, not fortified with iron, and there is a clear risk of harm tothe health of infant and young children if these products are fed regularly. The marketing messages and labelling on squeeze pouches are misleading and do not support WHO or Australian NHMRC recommendations for breastfeeding or appropriate introduction of complementary foods and labelling of products. There is an urgent need for improved regulation of product composition, serving sizes and labelling to protect infants and young children aged 0-36 months and better inform parents.

Infant Feeding, Gut Permeability, and Gut Inflammation Markers.

OBJECTIVES: Increased gut permeability and gut inflammation have been linked to the development of type 1 diabetes. Little is known on whether and how intake of different foods is linked to these mechanisms in infancy. We investigated whether the amount of breast milk and intake of other foods are associated with gut inflammation marker concentrations and permeability. METHODS: Seventy-three infants were followed from birth to 12 months of age. Their diet was assessed with structured questionnaires and 3-day weighed food records at the age of 3, 6, 9, and 12 months. Gut permeability was assessed with the lactulose/mannitol test and fecal calprotectin and human ß-defensin-2 (HBD-2) concentrations were analyzed from stool samples at the age of 3, 6, 9, and 12 months. The associations between foods and gut inflammation marker concentrations and permeability were analyzed using generalized estimating equations. RESULTS: Gut permeability and gut inflammation marker concentrations decreased during the first year of life. Intake of hydrolyzed infant formula ( P = 0.003) and intake of fruits and juices ( P = 0.001) were associated with lower intestinal permeability. Intake of fruits and juices ( P < 0.001), vegetables ( P < 0.001), and oats ( P = 0.003) were associated with lower concentrations of HBD-2. Higher intake of breast milk was associated with higher fecal calprotectin concentrations ( P < 0.001), while intake of fruits and juices ( P < 0.001), vegetables ( P < 0.001), and potatoes ( P = 0.007) were associated with lower calprotectin concentrations. CONCLUSIONS: Higher intake of breast milk may contribute to higher calprotectin concentration, whereas several complementary foods may decrease gut permeability and concentrations of calprotectin and HBD-2 in infant gut.

Infant egg consumption during introduction to solid food remains low in the United Kingdom but increases with infant age and a baby-led weaning approach.

BACKGROUND: As a nutritious food-providing protein, essential fatty acids, vitamin D, iodine and choline eggs have historically been central to an infant weaning diet. However, food poisoning scares and allergy concerns have contributed to low consumption among infants aged 6-12 months. METHODS: This paper presents a secondary data analysis of infant egg exposure and intake using three weaning data sets: a 7-day food frequency questionnaire (n = 297), a 24-h recall (n = 180) and a 3-day weighed food diary (n = 71). Egg introduction, frequency of consumption and intake in grams were analysed for infants aged 6-8, 9-10 and 11-12 months). Comparisons were made by whether infants were following a baby-led approach to weaning (where infants self-feed family foods) or a traditional approach where pureed foods are given alongside finger foods. Data were collected in the United Kingdom between 2015 and 2018. RESULTS: Our data showed that despite introduction being recommended from the start of weaning at 6 months of age by the Department of Health, just 54% of infants aged 6-8 months had ever been offered eggs. Average egg intake was one to two times per week, increasing with age. However, in terms of frequency and grams consumed, our data suggest a small increase in consumption compared with previous research, although limitations of our smaller sample size should be noted. Finally, a baby-led approach was associated with increased exposure and consumption; baby-led infants consumed eggs twice as frequently as spoon-fed infants. CONCLUSIONS: The findings have important implications for public health messaging and for supporting families in introducing solid foods.

Associations between early introduction to complementary foods, subsequent cereal-added bottle feeding and daily macronutrient intake among infants.

Introducing complementary foods early during infancy has been associated with an increased risk of overweight later in life, but the pathway is an understudied topic. Hence the study was conducted with low-income and primarily minority mother-infant dyads to: 1) understand how the introduction of complementary foods prior to 4 months was associated with socio-demographic characteristics and food security status; 2) determine the association between early introduction to complementary foods and breastfeeding and adding cereal into the bottle in later infancy (i.e., at 6 and 9 months), and; 3) examine how adding infant cereal into the bottle was related to daily calorie and macronutrient intake in infancy. We conducted interviews with mothers (n = 201) at 4 months of age and 24-h feeding recalls at age 6 and 9 months. Results indicated that 29% of the infants were fed complementary foods before 4 months of age. Introducing complementary foods early was negatively associated with breastfeeding and positively associated with adding cereal into the bottle at 6-months. This practice was more common among those who experienced marginal to very low levels of food security. Comparing by race/ethnicity, Latinx mothers were significantly less likely to introduce solids early. After controlling for sex, infants fed cereal in the bottle were consuming significantly more calories compared to their counterparts. Specifically, adding cereal into the bottle resulted in approximately 10% additional daily calorie intake among infants. Understanding how these feeding practices affect appetite development and weight status during infancy is warranted.

Prevalence and maternal determinants of early and late introduction of complementary foods: results from the Growing Up in New Zealand cohort study.

A nationally generalisable cohort (n 5770) was used to determine the prevalence of non-timely (early/late) introduction of complementary food and core food groups and associations with maternal sociodemographic and health behaviours in New Zealand (NZ). Variables describing maternal characteristics and infant food introduction were sourced, respectively, from interviews completed antenatally and during late infancy. The NZ Infant Feeding Guidelines were used to define early (≤ 4 months) and late (≥ 7 months) introduction. Associations were examined using multivariable multinomial regression, presented as adjusted relative risk ratios and 95 % confidence intervals (RRR; 95% CI). Complementary food introduction was early for 40·2 % and late for 3·2 %. The prevalence of early food group introduction were fruit/vegetables (23·8 %), breads/cereals (36·3 %), iron-rich foods (34·1 %) and of late were meat/meat alternatives (45·9 %), dairy products (46·2 %) and fruits/vegetables (9·9 %). Compared with infants with timely food introduction, risk of early food introduction was increased for infants: breastfed < 6months (2·52; 2·19-2·90), whose mothers were < 30 years old (1·69; 1·46-1·94), had a diploma/trade certificate v. tertiary education (1·39; 1·1-1·70), of Maori v. European ethnicity (1·40; 1·12-1·75) or smoked during pregnancy (1·88; 1·44-2·46). Risk of late food introduction decreased for infants breastfed < 6 months (0·47; 0.27-0·80) and increased for infants whose mothers had secondary v. tertiary education (2·04; 1·16-3·60) were of Asian v. European ethnicity (2·22; 1·35, 3·63) or did not attend childbirth preparation classes (2·23; 1·24-4·01). Non-timely food introduction, specifically early food introduction, is prevalent in NZ. Interventions to improve food introduction timeliness should be ethnic-specific and support longer breast-feeding.

Nutri-Score: Its Benefits and Limitations in Children's Feeding.

Reducing the burden of noncommunicable diseases (NCDs) is one of the top priorities of public health policies worldwide. One of the recognized means of achieving this objective is to improve the diet quality. The Nutri-Score (N-S) is a [five-color-A, B, C, D, E letters] front-of-pack labeling logo intended to help consumers quickly identify the healthier prepackaged foods within a food category. Available studies have shown that the N-S is an efficient tool to achieve this aim in terms of consumers' awareness, perception, understanding, and purchasing and that its use may help to reduce the prevalence of NCDs. The N-S is currently implemented on a voluntary basis in 7 European countries and a discussion is underway within the European Commission to achieve a harmonized mandatory label. However, no study on the putative impact of the N-S on children's dietary patterns and health is available. The N-S is not applicable to infants' and young children's formulas and to specific baby foods, the compositions of which are already laid down in European Union regulations. The N-S does not replace age-appropriate dietary guidelines. As children consume an increasing number of adult type and processed foods, the relevance of the N-S for children should be evaluated considering the children's high specific requirements, especially in younger children. This is especially necessary for fitting fat and iron requirements, whereas protein-rich foods should be better framed. Moreover, efforts should be made to inform on how to use the N-S and in education on healthy diets.

Guideline for complementary feeding of infants and young children 6­23 months of age

Complementary feeding, defined as the process of providing foods in addition to milk when breast milk or milk formula alone are no longer adequate to meet nutritional requirements, generally starts at age 6 months and continues until 23 months of age, although breastfeeding may continue beyond this period (4). This is a developmental period when it is critical for children to learn to accept healthy foods and beverages and establish long-term dietary patterns (5). It also coincides with the peak period for risk of growth faltering and nutrient deficiencies (6). The immediate consequences of malnutrition during these formative years ­ as well as in utero and the first 6 months of life ­ include impaired growth, significant morbidity and mortality, and delayed motor, cognitive, and socio-emotional development. It can later lead to increased risk of noncommunicable diseases (NCDs). In the long term, undernutrition in early childhood leads to reduced work capacity and earnings and, among girls, reduced reproductive capacity (6). Inappropriate complementary feeding can result in overweight, type 2 diabetes and disability in adulthood (7). The first two years of life are also a critical period for brain development, the acquisition of language and sensory pathways for vision and hearing, and the development of higher cognitive functions (8). Purpose of the guideline This guideline provides evidence-based recommendations on complementary feeding of infants and young children 6­23 months of age living in low, middleand high-income countries. It considers the needs of both breastfed and nonbreastfed children. These are public health recommendations, recognizing that children should be managed individually so that inadequate growth, overweight, or other adverse outcomes are identified, and appropriate action taken. This guideline does not address the needs of pre-term and low-birthweight infants, children with or recovering from acute malnutrition and serious illness, children living in emergencies, or children who are disabled. Except for children with disabilities, the needs of these other groups of children are addressed in other WHO guidelines.
