RESUMO

La leche humana es el estándar de oro para la nutrición del bebé y debe iniciarse en la primera hora de vida. La leche de vaca, de otros mamíferos o las bebidas vegetales no se deben ofrecer antes del año de vida. Sin embargo, algunos niños requieren, al menos en parte, de fórmulas infantiles. Aun con las sucesivas mejoras a lo largo de la historia mediante la incorporación de oliogosacáridos, probióticos, prebióticos, sinbióticos y postbióticos, las fórmulas infantiles siguen siendo perfectibles para reducir la brecha de salud entre los bebés amamantados y aquellos alimentados con fórmula. En este sentido, se espera que la complejidad de las fórmulas siga aumentando a medida que se conozca mejor cómo modular el desarrollo de la microbiota intestinal. El objetivo de este trabajo fue realizar una revisión no sistemática del efecto de los diferentes escenarios lácteos sobre la microbiota intestinal.


Human milk is the gold standard for infant nutrition, and breastfeeding should be started within the first hour of life. Cow's milk, other mammalian milk, or plant-based beverages should not be offered before 1 year of age. However, some infants require, at least in part, infant formulas. Even with subsequent enhancements throughout history, with the addition of oligosaccharides, probiotics, prebiotics, synbiotics, and postbiotics, infant formulas still have room for improvement in reducing the health gap between breastfed and formula-fed infants. In this regard, the complexity of infant formulas is expected to continue to increase as the knowledge of how to modulate the development of the gut microbiota is better understood. The objective of this study was to perform a non-systematic review of the effect of different milk scenarios on the gut microbiota.

RESUMO

Infant formula intake is recommended to ensure comprehensive nutritional and caloric fulfillment when exclusive breastfeeding is not possible. However, similarly to breast milk, infant formulas may also contain pollutants capable of inducing endocrine-disrupting and neurotoxic effects. Thus, considering the sensitivity of their developing physiological systems and that infants have heightened susceptibility to environmental influences, this study was aimed at assessing the contents of essential elements, and inorganic and organic pollutants in infant formulas marketed in Brazil. Additionally, health risk assessments for selected contaminants were also performed. Measured contents of essential elements (Ca, Fe, Mg, Mn, Cu, Se, and Zn) were congruent with label information. Nevertheless, some toxic elements (Pb, Cd, As, Ni, and Al) were also detected. Notably, in the upper-bound scenario, Pb and Cd surpassed established threshold values when comparing the estimated daily intake (EDI) and tolerable daily intake (TDI - 3.57 and 0.36 µg/kg bw, respectively). Bisphenol P (BPP) and benzyl butyl phthalate (BBP) were frequently detected (84 % detection rate both) with elevated contents (BPP median = 4.28 ng/g and BBP median = 0.24 ng/g). Furthermore, a positive correlation (0.41) was observed between BPP and BBP, implying a potential co-occurrence within packaging materials. Methyl-paraben also correlated positively with BBP (0.57), showing a detection rate of 53 %. The cumulative PBDE contents ranged from 0.33 to 1.62 ng/g, with BDE-154 and BDE-47 the dominant congeners. When comparing EDI values with TDIs, all organic pollutants remained below the thresholds across all exposure scenarios. Moreover, non-carcinogenic risks were below the threshold (HQ > 1) when dividing the EDIs by the respective reference doses for chronic exposure. While the current findings may suggest that infant formula intake poses no immediate risk in terms of the evaluated chemicals, it remains imperative to conduct further research to safeguard the health of infants considering other chemicals, as well as their potential cumulative effects.

RESUMO

Postbiotics were defined in 2021 by the International Scientific Association for Probiotics and Prebiotics (ISAPP) as a "preparation of inanimate microorganisms and/or their cellular components that confers a health benefit to the host." The field of postbiotics is a new area within the biotics family; numerous products have already been developed for clinical applications, such as immune stimulation, the management of diarrhea in children and adults, the management of irritable bowel syndrome, and 3 infant formulas. In particular, infant formulas with postbiotics obtained from milk fermented with Bifidobacterium breve C50 and Streptococcus thermophilus O65 -and their metabolites-, including the oligosaccharide 3'-GL, have demonstrated to be safe and to contribute to the development of the gut microbiota and the gutassociated immune system. These modifications help to prevent and manage functional gastrointestinal disorders in infants.

RESUMO

Introduction: breastfeeding is the most effective way to feed the child in the first six months of life exclusively and up to two years as a complementary form, as it provides a healthy development. However, in some situations it is impossible among them in children with food allergies such as Cow's Milk Protein Allergy (APLV). This condition can be defined as an adverse reaction of the immune system, caused by antigens present in the food that triggers the allergy.Objective: analyze the information on the labeling of infant formulas for infants with allergies to cow's milk protein (APLV), sold in pharmacies in Sobral/CE.Methods: cross-sectional, exploratory, quantitative and qualitative study. After data collection, the labels were analyzed based on a check list composed by the current legislation in accordance with RDC 45/2011, measuring the number of adjustments and inadequacies.Results: of the seven formulas analyzed, five were 100% adequate, when considering all the provisions that made up the check list. Of these were FAB-1 B, FAB-1 C, FAB-1 E, FAB-1 F, FAB-2 A, they were all in accordance with the dimensions established by RDC 45/2011, it is already in relation to formulas with inadequacy we observed that FAB-1 A was 2.22% in dimension two in which the micronutrient riboflavin was above the recommended range and FAB-1 D was 2.22% in dimension two, the carbohydrate macronutrient above the recommended range. In view of this, what we observed was that most of the formulas analyzed were within the labeling standards specified in Resolution RDC 45/2011, despite the many regulatory standards that govern the labeling and marketing of infant foods, it was realized that there is still a need for regulation stricter in this regard so that the legislation is fully complied with.Conclusion: according to what was evaluated about formulas for infants with APLV in relation to the labeling standards of the current legislation, some inadequacies were found. Therefore, this study showed a greater number of non-conformities in relation to the essential characteristics of composition and quality, despite the many regulatory standards that govern the labeling and marketing of infant foods, it is clear that they are still not fully complied with. It was found that we still need to evolve in the Elaboration, execution and inspection of the labels of formulas for infants with Allergy to Cow's Milk Protein (APLV), in order to minimize these non-conformities and offer the best food within the recommended standard, however these studies are necessary in order to better show and discuss the legislation referring to these products.


Introdução: a amamentação é a forma mais eficaz de alimentar a criança nos primeiros seis meses de vida exclusivamente e até os dois anos como forma complementar, pois proporciona um desenvolvimento saudável. No entanto, em algumas situações, é impossível entre eles em crianças com alergia alimentar, como a alergia à proteína do leite de vaca (APLV). Essa condição pode ser definida como uma reação adversa do sistema imunológico, causada por antígenos presentes nos alimentos que desencadeiam a alergia.Objetivo: analisar as informações sobre a rotulagem de fórmulas infantis para lactentes com alergia à proteína do leite de vaca (APLV), comercializadas em farmácias de Sobral/CE.Método: estudo transversal, exploratório, quantitativo e qualitativo. Após a coleta de dados, os rótulos foram analisados com base em um check list composto pela legislação vigente de acordo com a RDC 45/2011, mensurando o número de adequações e inadequações.Resultados: das sete fórmulas analisadas, cinco foram 100% adequadas, quando consideradas todas as disposições que compunham o check list. Destes eram FAB -1 B, FAB -1 C, FAB -1 E, FAB -1 F, FAB -2 A, todos estavam de acordo com as dimensões estabelecidas pela RDC 45/2011, já está em relação às fórmulas com inadequação observamos que FAB-1 A foi de 2,22% na dimensão dois em que a micronutriente riboflavina estava acima da faixa recomendada e FAB-1 D foi de 2,22% na dimensão dois, o macronutriente carboidrato acima da faixa recomendada. Diante disso, o que observamos foi que a maioria das fórmulas analisadas estava dentro dos padrões de rotulagem especificados na Resolução, apesar das inúmeras normas regulamentadoras que regem a rotulagem e comercialização de alimentos infantis, percebeu-se que ainda existe necessidade de regulamentação mais rigorosa nesse sentido, para que a legislação seja integralmente cumprida.Conclusão: de acordo com o que foi avaliado sobre as fórmulas para lactentes com APLV em relação aos padrões de rotulagem da legislação vigente foram encontradas algumas inadequações. Portanto esse estudo apresentou maior número de inconformidades em relação as características essênciais de composição e qualidade, apesar das muitas normas regulamentadoras que regem a rotulagem e comercialização de alimentos infantis, percebe-se que ainda não são totalmente cumpridas. Verificou-se que ainda precisamos evoluir na Elaboração, execussão e fiscalização dos rótulos das fórmulas para lactentes com Alergia a Proteína do Leite de Vaca (APLV), a fim de minimizar essas não conformidades e ofererer o melhor alimento dentro do padrão preconizado, no entanto faz-se necessários estes estudos a fim de mostrar e discutir melhor as legislações referentes a esses produtos.

Os valores mínimos e máximos para o índice de validade de conteúdo (IVC) foi, respectivamente, 0,88 e 0,96. O coeficiente de correlação intraclasse (CCI) e Alfa de Cronbach (α) foi >0,80 em mais de 90% dos itens avaliados. Os valores mínimos e máximos para o índice de validade de aparência (IVA) foi, respectivamente, 0,73 e 0,93. O teste de Kruskal Wallis não apresentou diferença significativa durante as avaliações (p valor>0,05) para os blocos da versão rotina e versão gestão. As versões do instrumento apresentaram em mais de 80% dos blocos α e CCI>0,80. Portanto, o instrumento apresentou conteúdo e aparência validados tendo reprodutibilidade e confiabilidade, ou seja, viabilidade de utilização na prática do nutricionista.


Abstract This work aimed to draft and validate a checklist of the production processes of pediatric diets for use in hospital lactaries. A bibliographic search was carried out in order to draft the instrument. Content validation was performed with 5 experts, using the Delphi technique and the 5-point Likert scale. Appearance validation was performed by 3 nutritionists, in the same environment, day, and time. The instrument included a header, a guide to completion instructions, and 225 assessment items that obtained validated content. The minimum and maximum values for the content validity index (CVI) were 0.88 and 0.96, respectively. The intraclass correlation coefficient (ICC) and Cronbach's alpha (α) was >0.80 in more than 90% of the items evaluated. The minimum and maximum values for the Appearance Validity Index (AVI) were, respectively, 0.73 and 0.93. The Kruskal Wallis test showed no significant difference during the evaluations (p-value>0.05) for the blocks of the routine version and the management version. The instrument versions presented in more than 80% of the α and ICC blocks > 0.80. Therefore, the instrument presented validated content and appearance, presenting reproducibility and reliability in terms of the feasibility of use in a nutritionist's practice.

RESUMO

El parto prematuro, las cesáreas, los antibióticos y la lactancia materna limitada contribuyen al aumento de enfermedades crónicas no transmisibles. El objetivo fue realizar una revisión descriptiva del uso de probióticos en pediatría, con foco en la cepa Lactobacillus rhamnosus GG. Ciertos probióticos han demostrado ser eficaces en la diarrea aguda y en la diarrea asociada a antibióticos. L. rhamnosus GG y Saccharomyces boulardii pueden acortar la duración y los síntomas. L. reuteri DSM 17938 y L. rhamnosus GG fueron efectivos para el abordaje del cólico del lactante. El uso de esta cepa en fórmulas infantiles para alergia a las proteínas de leche de vaca promovería la adquisición más temprana de tolerancia. En la prevención de dermatitis atópica, la administración de L. rhamnosus GG durante el embarazo redujo su manifestación en el bebé. El empleo de probióticos como coadyuvantes es una posibilidad para considerar en la práctica pediátrica actual.


Preterm birth, C-sections, antibiotics, and limited breastfeeding contribute to the increase in noncommunicable diseases. Our objective was to perform a descriptive review of probiotic use in pediatrics, focused on Lactobacillus rhamnosus GG. Certain probiotics have demonstrated to be effective in acute diarrhea and antibiotic-associated diarrhea. L. rhamnosus GG and Saccharomyces boulardii may shorten their duration and symptoms. L. reuteri DSM 17938 and L. rhamnosus GG were effective to manage infant colic. The use of this strain in infant formulas for cow's milk protein allergy may promote an earlier tolerance acquisition. In relation to the prevention of atopic dermatitis, the administration of L. rhamnosus GG during pregnancy reduced its development in the infant. The use of probiotics as adjuvants is a possibility to consider in current pediatric practice.

RESUMO

Infant formulas, designed to provide similar nutritional composition and performance to human milk, are recommended when breastfeeding is not enough to provide for the nutritional needs of children under 12 months of age. In this context, the present study aimed to assess the protein quality and essential amino acid content of both starting (phase 1) and follow-up (phase 2) formulas from different manufacturers. The chemical amino acid score and protein digestibility corrected by the amino acid score were calculated. The determined protein contents in most formulas were above the maximum limit recommended by FAO and WHO guidelines and at odds with the protein contents declared in the label. All infant formulas contained lactoferrin (0.06 to 0.44 g·100 g-1) and α-lactalbumin (0.02 to 1.34 g·100 g-1) below recommended concentrations, whereas ĸ-casein (8.28 to 12.91 g·100 g-1), α-casein (0.70 to 2.28 g·100 g-1) and ß-lactoglobulin (1.32 to 4.19 g·100 g-1) were detected above recommended concentrations. Essential amino acid quantification indicated that threonine, leucine and phenylalanine were the most abundant amino acids found in the investigated infant formulas. In conclusion, infant formulas are still unconforming to nutritional breast milk quality and must be improved in order to follow current global health authority guidelines.
