BACKGROUND: Human breast milk has a high microRNA (miRNA) content. It remains unknown whether and how milk miRNAs might affect intestinal gene regulation and homeostasis of the developing microbiome after initiation of enteral nutrition. However, this requires that relevant milk miRNA amounts survive gastrointestinal passage, are taken up by cells, and become available to the RNA interference (RNAi) machinery. It seems important to dissect the fate of these miRNAs after oral ingestion and gastrointestinal passage...

BACKGROUND: Approximately 84% of fatty acids contained in coconut oil (CO) are saturated fatty acids (SFA), and approximately 47% of the SFA are lauric acid with 12 carbon atoms. Lauric acid carbon chain length is intermediate between medium and long chain fatty acids. We examined how CO acts on lipid-related substances in the blood to determine whether its properties were similar to medium-chain fatty acids (MCFA) or long-chain fatty acids (LCFA). METHODS: This is a randomized controlled single-blind crossover study...

The National Health and Nutrition Examination Survey (NHANES) needs urgent attention to ensure its future, which is facing emerging challenges associated with data collection, stagnant funding that has undercut innovation, and the increased call for granular data for subpopulations and groups at risk. The concerns do not rest merely on securing more funding, but focus on the need for a constructive review of the survey to explore new approaches and identify appropriate change. This white paper, developed under the auspices of the American Society for Nutrition's Committee on Advocacy and Science Policy (CASP), is a call to the nutrition community to advocate for and support activities to prepare NHANES for future success in a changing nutrition world...

BACKGROUND: Current gestational weight change (GWC) recommendations for those with obesity were established with limited evidence of the pattern and timing of weight change across pregnancy. Likewise, the recommendation of 5-9kg does not differentiate by obesity severity. OBJECTIVES: We sought to describe GWC trajectory classes by obesity grade and associated infant outcomes among a large, diverse cohort. METHODS: The study population included 22,355 singleton pregnancies individuals with obesity (BMI≥30...

BACKGROUND: Type 2 diabetes (T2DM) and poor glucose regulation in the immediate postprandial period are both associated with impairments in cognitive function. There is evidence that foods that generate a better postprandial glycemic response, such as low GI foods (which produce a lower glycemic peak, less variability, and a more sustained decline), are associated with cognitive benefits over the morning. However, the potential impact of consuming multiple meals of this nature over the course of a day on cognition in T2DM has not been explored...

BACKGROUND: A multivariable logistic regression model resulting from a case-control study of nutritional rickets in Nigerian children suggested that higher levels of serum 25-hydroxyvitamin D [25(OH)D] may be required to prevent nutritional rickets in populations with low calcium intakes. OBJECTIVE: This current study evaluates if adding serum 1,25-dihydroxyvitamin D (1,25(OH)2 D) to that model shows that increased levels of serum 1,25(OH)2 D are independently associated with the risk of children on low-calcium diets having nutritional rickets...
