The Infant Diet Quality Index Predicts Dietary and Adiposity Outcomes in US Children 2 to 4 years old

Investigation of the formation of furfural compounds in apple products treated with pasteurization and high pressure processing

The thermal treatment carried out in the processing of apple products is very likely to induce Maillard reaction to produce furfurals, which have raised toxicological concerns. This study aimed to elucidate the formation of furfural compounds in apple products treated with pasteurization and high pressure processing (HPP). The method for simultaneous determination of five furfural compounds including 5-hydroxymethyl-2-furfural (5-HMF), furfural (F), 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF), 2-acetylfuran (FMC), and 5-Methyl-2-furfural (MF) using high performance liquid chromatography equipped with diode array detector (HPLC-DAD) was successfully developed and validated. All five furfurals exhibited an increasing trend after the pasteurization treatment of apple clear juice, cloudy juice, and puree. 5-HMF, F, FMC, and MF were increased significantly during the precooking of apple puree. Whereas there was no significant change in the furfurals formation after apple products treated with high pressure processing (HPP) with 300 MPa and 15 min. Based on the variation of the fructose, glucose and sucrose detected in apple products after thermal treatment, it revealed that the saccharides and thermal treatment have great effect on the furfural compounds formation. The commercial fruit juice samples with different treatments and fruit puree samples treated with pasteurization were also analyzed. Five furfurals were detected more frequently in the fruit juice samples treated with pasteurization or ultra-high temperature instantaneous sterilization (UHT) than those treated with HPP. 5-HMF and FMC were detected in all fruit puree samples treated with pasteurization, followed by F, MF, and HDMF with the detection rate of 79.31 %, 72.41 %, and 51.72 %. The results could provide a reference for risk assessment of furfural compounds and dietary guidance of fruit products for human, especially for infants and young children. Moreover, moderate HPP treatment with 300 MPa and 15 min would be a worthwhile alternative processing technology in the fruit juice and puree production to reduce the formation of furfural compounds.

Factors impacting complementary feeding advice given by paediatricians in Cyprus

BACKGROUND

Complementary feeding has long-term effects on health but there is heterogeneity in recommendations across Europe. Recommendations include responsive feeding practices and nutritional needs but there is a debate in primary paediatricians as to which one should be the main criterion for complementary feeding. This pilot study investigated (i) the factors affecting the recommendations of paediatricians in Cyprus for starting complementary feeding, (ii) whether their main criterion is the developmental readiness or the nutritional needs of the infant and (iii) how this priority influences recommendations.

METHODS

The 11-item questionnaire was completed by 73 Cypriot paediatricians.

RESULTS

Approximately 66% of paediatricians recommended starting complementary feeding between 5 and 6 months, 29% between 4 and 5 and 3% between 6 and 7 months. Predefined schemes were recommended by ∼25% of paediatricians, baby-led weaning by 14% and 58% of paediatricians recommended either modality depending on the family circumstances whilst 4% involve the mother in the decision process. Approximately 64% of paediatricians recommended the introduction of parent's diet after the first year of life. Approximately 55% of paediatricians chose developmental readiness and 45% nutritional needs of the infant as their primary criterion for starting complementary feeding. Paediatricians who prioritized developmental readiness were more likely to be younger, less likely to advice on meat quantity and less likely to follow good nutritional practice.

CONCLUSIONS

The younger the paediatrician the more likely they are to prioritize developmental readiness over nutritional needs of the infant for complementary feeding. Paediatricians who prioritized developmental readiness were also less likely to provide nutritional advice.

Differences in Infant Diet Quality Index by Race and Ethnicity Predict Differences in Later Diet Quality

BACKGROUND

Racial and ethnic disparities in infant-feeding practices may negatively influence diet quality and health.

OBJECTIVES

This study investigated the racial, ethnic, and language (English or Spanish) differences in infant diet quality, later diet quality, and weight status at 2-5 y, and whether these differences were explained through infant diet quality among participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

METHODS

Using the WIC Infant and Toddler Feeding Practices Study-2 (unweighted n = 2663; weighted n = 362,712), relationships between the Infant Dietary Quality Index (IDQI; range 0-1) and Healthy Eating Index-2020 (HEI-2020; range 0-100) and BMI z-score (BMIz) at 2-5 y were analyzed by race, ethnicity, and language preference [Hispanic Spanish-speaking, Hispanic English-speaking, non-Hispanic (NH) White, and NH Black participants]. Statistical interaction between IDQI and each group was evaluated in multivariable models. The mediation of each group through the IDQI was assessed using causal mediation methods.

RESULTS

Differences in IDQI [mean (standard deviation)] were observed between Hispanic Spanish-speaking participants [0.41 (0.10)], Hispanic English-speaking participants [0.37 (0.10)], NH White participants [0.36 (0.10)], and NH Black participants [0.35 (0.09)], P < 0.001. Differences in HEI-2020 occurred at 2-5 y, with the Hispanic Spanish-speaking participants having consistently higher HEI-2020 scores. Differences in BMIz were observed at 5 y, with higher scores among Hispanic Spanish-speaking participants. Interaction between race, ethnicity, and IDQI was observed for all outcomes except for BMIz at 3 y. Through mediation, IDQI explained 13%-20% of the difference in HEI-2020 scores between Hispanic Spanish-speaking and NH White participants at 2-5 y. IDQI explained 22%-25% of the difference in HEI-2020 scores between the Hispanic Spanish-speaking and NH Black participants at 4 y and 5 y.

CONCLUSIONS

Higher infant diet quality scores observed in Hispanic Spanish-speaking participants explain some of the racial and ethnic differences observed in later diet quality, suggesting that improving infant diet quality may help reduce diet disparities during early childhood.
