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.展开更多

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展开更多

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.展开更多
