Timing of Resistance Exercise and Cardiometabolic Outcomes in Adults with Prediabetes: A Secondary Analysis.

The objective of this study was to explore if the time of day (AM vs PM) resistance exercise is performed influences glucose and insulin concentrations, body composition, and muscular strength in adults with prediabetes. A secondary data analysis was conducted using data from the "Resist Diabetes" study, a phase II exercise intervention. Participants (Age:59.

Associations of Food Group Intakes with Serum Carbon Isotope Ratio Values in Youth: Results from 2 Prospective Pediatric Cohort Studies.

Background: The carbon isotope ratio (CIR) is a candidate biomarker for sugar-sweetened beverage (SSB) intake in the United States. However, research specific to youth, who differ in their physiology and dietary patterns compared with adults, is lacking.

Objectives: We evaluated longitudinal associations of SSB intakes across childhood/adolescence with serum CIR.

Neural and metabolic factors in carbohydrate reward: Rationale, design, and methods for a flavor-nutrient learning paradigm in humans.

Overconsumption of ultra-processed foods (UPFs), which are linked with adverse health outcomes, is a growing public health concern. UPFs deliver highly bioavailable calories rapidly, which may contribute to their reinforcing potential and drive overconsumption. Our primary aim is to test the role of speed of nutrient availability on reward learning.

Associations Between Hydration Status and Executive Function in Middle-Aged and Older Adults: Findings from the Nationally Representative Health and Retirement Study.

The purpose of the current study is to examine the association between hydration status and cognitive function in middle-aged and older adults, drawing from a large, nationally representative sample in the United States and using a comprehensive set of executive function performance measures. We utilized data from the Health and Retirement Study to conduct twelve, three-stage hierarchical regressions on hydration status and executive function performance of older adults. Cognitive performance scores on the Trail Making A, Symbol Digit Modalities, and Letter Cancellation tests significantly differed by hydration status, and these outcomes follow a curvilinear pattern, such that performance scores are lower for those who are hyper-hydrated or dehydrated relative to those who are euhydrated or near-dehydration.

Neuroprotective Dietary Patterns and Longitudinal Changes in Cognitive Function in Older Adults.

Background: Numerous studies have examined the association between neuroprotective diets and cognitive function during aging; however, these studies have produced divergent findings. Some studies find that greater adherence to these dietary patterns is associated with preserved cognition, whereas others find no effect.

Objective: The aim of this study was to examine the association of the Mediterranean, the Dietary Approach to Stop Hypertension (DASH), and Mediterranean-DASH Intervention for Neurodegeneration Delay (MIND) dietary patterns with global cognition over 4 waves of data from the Health and Retirement Study, a longitudinal panel study conducted at the University of Michigan.
