Gastrointestinal tolerability of organic infant formula compared to traditional infant formula: A systematic review

BACKGROUND Infants'nutrition significantly influences their growth,development,and overall well-being.With the increasing demand for organic infant formula driven by the perception of health benefits and growing awareness of natural feeding options,it is crucial to conduct a comparative analysis of the gastrointestinal tolerability between organic and traditional infant formulas.AIM To provide a concise and precise analysis of the gastrointestinal tolerability of organic infant formula compared to traditional infant formula.Due to limited direct comparisons,the review synthesizes available literature on each formula type,presenting insights into their potential effects on infants'digestive health.METHODS An extensive literature search was conducted,compiling studies on organic and traditional infant formulas,their compositions,and reported effects on gastrointestinal tolerability.We searched academic databases such as PubMed and Google Scholar and specialized nutrition,paediatrics,and infant health journals using relevant keywords till October 1,2023.RESULTS Although specific comparative studies are scarce and formula heterogeneity is a significant limitation,this systematic review provides an in-depth understanding of organic infant formulas'composition and potential benefits.While scientific evidence directly comparing gastrointestinal tolerability is limited,organic formulas strive to use carefully selected organic ingredients to imitate breast milk composition.Potential benefits include improved lipid profiles,higher methionine content,and decreased antibiotic-resistant bacteria levels.Understanding the gastrointestinal tolerability of organic and traditional infant formulas is crucial for parents and healthcare providers to make informed decisions.CONCLUSION Despite limitations in direct comparisons,this systematic review provides insights into the composition and potential benefits of organic infant formulas.It emphasizes the need for further research to elucidate their gastrointestinal effects comprehensively.

The Effects of High Energy and Micronutrient Supplementation on Iron Status in Nutritionally at Risk Infants

The study assessed the effects of supplementary feeding over 180 consecutive days on iron status of infants and toddlers at six tea plantation in West Java, Indonesia. The design used was a clinical trial: two eohorts (i.e., 12 and 18 months old children) and three treatment groups (i.e., energy + micronutrient, micronutrient alone, and placebo) per cohort. Every day except Sunday, the infants attended day-care centers. Twenty four centers and 136 infants were selected. The infants were screened for weight and length and those meeting the criteria (i.e., <-1 SD of length-for-age, and between -1 and -2 SD of weight-for-length of the NCHS reference) were included. The experimental unit was the day-care centers (DCC), where each DCC was randomly assigned to one of the three treatment. As expected, groups of energy + micronutrient and micronutrient alone of the 12 months cohort experienced a significant upward shift in hemoglobin, ferritin and TS and a downward change in FEP, while the values for the group of placebo remain about the same as at base line. In the first 6 month of treatments, the ANOVA for each iron indicator yielded significant main effects of treatment (P<0.01) and for Hb with (P =0.059) on 12 months cohort. On the other hand, the main effects of treatment on hemoglobin, TS, ferritin and FEP were not significant for the 18 months cohort. In the second 6 month of treatments, the only significant of the treatment effect (P<0.01) was in serum ferritin on 18-month cohort. Under these circumstances, energy has a positive role in improving iron stores. It is likely that the equilibrium of hemoglobin and each iron indicators were reached in 6 months of treatment except ferritin still continued to increase up to 12 month. The effects of treatment on the improvement of iron status was stronger in 12 months than in 18 months

Are Family Table Foods Appropriate for Infants? Comparing the Nutritional Quality of Homemade Meals Adapted from the Family’s Table Foods and Those Specially Prepared for Infants

The Brazilian Ministry of Health recommends that by 8 months of age, children should eat the same types of foods consumed by the other members of the family. Thus, this study sought to evaluate whether the nutritional composition of meals specially prepared (SM) for children aged 7 to 18 months in low-income families was superior to that of meals adapted (AM) from the family’s table foods. Protein, fat, carbohydrate, energy, dietary fiber, iron, sodium and sodium chloride values, were determined by chemical analyses and compared to dietetic guidelines. The infants’ hemoglobin levels were also investigated. In total, sixty samples of the infants’ lunch meal (51 AM and 9 SM) were taken for during a home visit. The values of protein, fat, carbohydrate, dietary fiber and energy of the AM were significantly lower, while the sodium and sodium chloride values were significantly higher, compared to those of the SM. The AM also contained significantly more water. No differences were seen with regard to iron values. Sodium chloride amounted for most of the sodium content. Neither the SM nor AM was adequate in terms of iron and sodium. All SM were adequate for protein and fat, whereas AM showed significantly more samples with inadequate energy levels. SM fell within the Acceptable Macronutrient Distribution Range, while AM fell below the lower value for fat and slightly above the upper value for carbohydrate. The prevalence of anemia was 60% in the study population (36/60). In conclusion, meals adapted from the family’s table foods showed a lower nutrient density and a less balanced macronutrient range when compared to meals specially prepared for infants. The main nutritional shortcomings, for both AM and SM, were the extremely low content of iron and the high content of sodium.

Trends of Laboratory-Detected Heavy Metals in Children: Solutions for Heavy Metal Contamination in Infant Food Products

In 2019, an investigation by the U.S. House of Representatives revealed major infant food conglomerates had products with high levels of arsenic, lead, cadmium, and mercury, posing concerns for infants’ vulnerability to the neurotoxic effects of these metals. Trends of laboratory-detected heavy metals were analyzed in children aged zero to five from 1999-2020, providing insights on heavy metal contamination in infant food products. Utilizing National Health and Nutrition Examination Survey (NHANES) data, mean heavy metal levels in children were calculated, considering gender, race, and income-to-poverty ratio as proxies for assessing associations with increasing heavy metal rates in infant food. Findings indicated an overall decrease in mean concentrations over time, though remaining elevated. Black children exhibited higher lead levels than the overall average, while the Asian subgroup displayed higher levels of total blood mercury and cadmium levels. Lack of internal standards in regulatory bodies, particularly the FDA, exacerbates the issue, with no legally enforceable guidelines or strict maximum levels for heavy metals in infant foods. Urgent FDA interventions are needed, addressing contamination at the sources of raw materials, implementing transparent and extensive product testing, and comprehensive manufacturer labeling to inform consumers about elevated heavy metal levels in infant products.

The effect of an early oral stimulation program on oral feeding of preterm infants

Purpose:To evaluate the effect of an oral stimulation program on preterm infants.Methods:Preterm infants(n=72)were randomly assigned to experimental and control groups.Controls(n=36)received routine care while the experimental group(n=36)received oral stimulation in addition to routine care.Postmenstrual age,total intake volume,body weight,the transition time from initiation of oral feeding to full oral feeding and feeding efficiency were calculated.Results:Postmenstrual age and full oral feeding weight were significantly lower in the experimental group(p<0.05).The time from initiation of oral feeding to full oral feeding was significantly shorter in the experimental group(p<0.05)while feeding efficiency was higher in the experimental group(p<0.05)compared to controls.No significant differences existed in hospital stay length or weight gain rate.Conclusions:An early oral stimulation program is beneficial in preterm infants.
