Nutritional physiology and body composition changes during a rapid ascent to high altitude
Applied Physiology, Nutrition, and Metabolism, Ahead of Print. Exposure to high altitude might cause the body to adapt with negative energy and fluid balance that compromise body composition and physical performance. In this field study involving 12 healthy adults, sex-balanced, and aged 29  ± 4 years with a body mass index of 21.6 ± 1.8 kg/m2, we investigated the effects of a 4-day trekking up to 4556 m a.s.l. on Monte Rosa (Alps, Italy). The food intake was recorded using food diaries and nutrient averages were calculated. The bio-impedance analysis was performed at low and h igh altitudes, and a wearable biosens...

Development of the Pediatric Integrated Nutrition Pathway for Acute Care (P-INPAC) using a modified Delphi technique
Applied Physiology, Nutrition, and Metabolism, Ahead of Print. One in three hospitalized children have disease-related malnutrition (DRM) upon admission to hospital, and all children are at risk for further nutritional deterioration during hospital stay; however, systematic approaches to detect DRM in Canada are lacking. To standardise and improve hospital care, the multidisciplinary pediatric working group of the Canadian Malnutrition Taskforce aimed to develop a pediatric, inpatient nutritional care pathway based on available evidence, feasibility of resources, and expert consensus. The working group (n  = 13) undertoo...

Women in Canada are consuming above the upper intake level of folic acid but few are meeting dietary choline recommendations in the second trimester of pregnancy: data from the CHILD cohort study
The objective of this study was to determine folic acid supplement use and dietary folate intakes in the second trimester (week 18) of pregnancy in women (n = 2996) in the Canadian CHILD cohort study. Vitamin B1 2 and choline intakes were also assessed because they are metabolically related to folate. The majority of participants (71.6%) were consuming a daily prenatal supplement. Twenty-eight percent of women (n = 847) reported consuming a folic acid supplement and of these women, 45.3% had daily supplem ental folic acid intakes above the upper intake level (UL; 1000 µg/day). Daily dietary folate intakes were (mean (...

What ’s the big IDEA? Incorporating inclusion, diversity, equity, and access (IDEA) in population health nutrition research and practice
Applied Physiology, Nutrition, and Metabolism, Ahead of Print. Historically, the constructs of inclusion, diversity, equity, and access (IDEA) have not been sufficiently considered or included in population health nutrition research and practice. Consequently, current nutrition assessment benchmarks and knowledge translation tools may not accurately or adequately reflect diversity in the Canadian population or produce meaningful dietary guidance. The purpose of this current opinion paper is to introduce the population health nutrition research and practice framework and explore the current application of IDEA within this f...

Repeated short cold-water immersions are sufficient to habituate to the cold, but do not lead to adaptations during exercise in normobaric hypoxia
Applied Physiology, Nutrition, and Metabolism, Ahead of Print. We sought to assess the effects of repeated cold-water immersions (CWI) on respiratory, metabolic, and sympathoadrenal responses to graded exercise in hypoxia. Sixteen (2 female) participants (age: 21.2 ±   1.3 years; body fat: 12.3 ± 7.7%; body surface area 1.87 ± 0.16 m2, VO2peak: 48.7 ± 7.9 mL/kg/min) underwent 6 CWI in 12.0 ± 1.2 °C. Each CWI was 5 min, twice daily, separated by ≥4 h, for three consecutive days, during which metabolic data were collected. The day before and after the repeated CWI intervention, participants ran in nor...

Metabolic remodeling of visceral and subcutaneous white adipose tissue during reacclimation of rats after cold
Applied Physiology, Nutrition, and Metabolism, Ahead of Print. Deciphering lipid metabolism in white adipose tissue (WAT) depots during weight gain is important to understand the heterogeneity of WAT and its roles in obesity. Here, we examined the expression of key enzymes of lipid metabolism and changes in the morphology of representative visceral (epididymal) and subcutaneous (inguinal) WAT (eWAT and iWAT, respectively)-in adult male rats acclimated to cold (4 ± 1 °C) for 45 days and reacclimated to room temperature (RT, 22 ± 1 °C) for 1, 3, 7, 12, 21, or 45 days. The relative mass of both depots decreased to a sim...

Are menstrual disturbances associated with an energy availability threshold? A critical review of the evidence
Applied Physiology, Nutrition, and Metabolism, Ahead of Print. Exercising women have a high prevalence of menstrual disturbances. In 2003, it was suggested that disruption in luteinizing hormone (LH) pulsatility occurs below a threshold of energy availability (EA) of 30  kcal/kg lean body mass (LBM)/day. This paper is a critical review of the evidence regarding the theory that disruptions to the reproductive axis and menstrual disturbances occur below the proposed threshold. Short-term laboratory studies demonstrated that 4–5 days of an EA below 30 kcal/kg LBM/ day, induced with or without exercise, decreased serum tri...
