The application of high resolution gas chromatography in combination with low resolution mass spectrometry with electron ionization and MS/MS detection (HRGC-MS/MS) is tested for its use in the analysis of PCDD/Fs in infant formulas. Development of the analytical method was based upon EPA directrices and international recommendations. Calibration linearity was tested and average relative response for any native and labelled compound over the five-point calibration range below 14% was found. The precision and accuracy of the proposed analytical procedure are also presented. Results obtained are in agreement with EPA criteria. The method is applied to the analysis of a number of initial and follow-on milk based infant formulas. In general, HRGC-MS/MS constitutes an interesting method for the analysis of dioxins in such matrices.

Barriers and drivers to exclusive breastfeeding in Kyrgyzstan: a qualitative study with mothers and health workers.
Int Breastfeed J

Behavioural and Cultural Insights Unit, WHO Regional Office for Europe, Copenhagen, Denmark.
Background: The WHO/UNICEF global nutrition target for exclusive breastfeeding for six months is at least 70% of infants by 2030. However, global prevalence rates are 48% with variations between countries and within regions. Kyrgyzstan has consistently high early breastfeeding initiation rates, yet exclusive breastfeeding for six months is 46%.

2'-Fucosyllactose (2'-FL) is the most abundant human milk oligosaccharide (HMO) and has been approved to be commercially added to infant formula. Microbial synthesis from exogenous lactose via metabolic engineering is currently the major approach to production of 2'-FL. Replacement of lactose with cheaper sugars such as glucose and sucrose has been studied to reduce the production costs.

Background: Early infant feeding is essential for children's development and future health, particularly in preventing obesity, which is the most common nutrition-related disorder in children worldwide.
Summary: Obesity, characterized by excess body fat and numerous complications, arises from a combination of genetic susceptibility and an obesogenic environment, including lifestyle behaviors related to energy balance. Eating habits start to be shaped early in life, making the introduction of solid foods a critical period.
Effects of Infant Formula Supplemented With Prebiotics on the Gut Microbiome, Gut Environment, Growth Parameters, and Safety and Tolerance: A Systematic Review and Meta-Analysis.
Nutr Rev
January 2025
Pennington Biomedical Research Center, Louisiana State University, Baton Rouge, LA 70808, United States.
Context: Prebiotics are often added to infant formulas to mimic the benefits of oligosaccharides found in human milk.
Objective: This systematic review and meta-analysis evaluated the effects of prebiotic-supplemented cow's milk-based formula on the gut microbiota, gut environment, growth parameters, and safety and tolerance in infants ≤6 months old, compared with a standard formula or human milk comparator.
Data Sources: Searches were performed in the PubMed, Embase, Cochrane Central Register of Controlled Trials, and ProQuest Dissertations & Theses databases.
Comparative analysis of the structure and content of N-glycans from different commercial whey protein materials.
J Food Sci
January 2025
College of Food Science and Engineering, Tianjin University of Science & Technology, Tianjin, China.
Infant formulas are constantly being updated and upgraded, and N-glycans are functional glycans that have not been fully exploited to date. Commercial whey protein materials are often used as basic ingredients in infant formulas. Therefore, it is important to study N-glycans in commercial whey protein materials.
