People with pre-diabetes may be reluctant to add fruit to their diets due to concerns around sugars. Our objective was to measure outcomes associated with potential adverse effects of ingesting fruit sugars while assessing metabolic benefits from eating nutrient-rich kiwifruit. Thirty-four people with pre-diabetes were randomized to receive two kiwifruit or 250 mL bottled water per day for 12-weeks; two people withdrew. The primary outcomes were between-group differences for glycated haemoglobin (HbA1c) and plasma [...]

Space flight imposes a myriad of adverse effects upon the human body. Improved in-flight nutritional strategies help mitigate those adverse effects. This review examines how space flight changes human physiology, and how improved in-flight nutritional strategies may address the unique dietary needs created by microgravity exposure. Dietary approaches and recommendations to address those needs are discussed. This review also describes food sustainability methods for long-term manned space flight, how precision nutri [...]

Poor lifestyle choices in adolescents, including low physical activity (PA), excess screen time, and unhealthy dietary habits, are major threats to their health in the future. Unhealthy behaviors such as insufficient PA, high TV time, and poor dietary choices also tend to cluster, but information on the combined association of screen time, sports participation, and dietary habits is limited in Austrian youth. To examine the association among these behaviors, 165 adolescents (74 girls and 91 boys) between 11 and 14 [...]

Major depressive disorder (MDD) is a debilitating illness that places a great burden on global health. A ketogenic diet, which has traditionally been used for treating refractory epileptic disorders, is being increasingly explored for its potential of alleviating other neuropsychiatric conditions. Providing an up-to-date summary on the ketogenic diet’s potential to alleviate MDD, its neurobiological basis, and preliminary clinical evidence. A structured literature survey was performed, and a narrative review was wr [...]

Parenteral nutrition (PN) is a complex medication administered to adult, pediatric, and neonatal patients. PN is recognized as a high-alert medication by the Institute for Safe Medication Practices (ISMP). The American Society for Parenteral and Enteral Nutrition (ASPEN) has published several key recommendations regarding safe use of PN. This manuscript will review several of the important PN papers published in 2020-2021 by ASPEN.

It is recommended that children ages 3-5 receive 180 minutes of physical activity a day, with at least 60 minutes of moderate-to-vigorous physical activity. Despite these recommendations, a majority of preschoolers are not provided opportunities in the early childhood education setting to meet these daily recommendations through either structured or unstructured physical activity. Accordingly, the number of young children identified as overweight or obese over the past couple of decades has increased. Critical to a [...]

Wheat bran cereals are an important source of dietary fibre. The aim of the study was to investigate if a high intake (120 g) of fibre rich breakfast cereal (which delivers the UK Government guidelines for fibre intake in one serving but is three-fold higher than the manufacturers recommended serving) has additional potential health benefits compared to the recommended serving (40 g, containing 11 g of dietary fibre). To assess this, the study determined the short chain fatty acid (SCFA) profiles in human faecal, u [...]

Poor dietary habits can lead to obesity and insulin resistance—both of which can impair basal heat shock protein (HSP) expression and the HSP stress response in skeletal muscle. It remains unclear if impairments in HSP expression occur during the early stages of diet-induced obesity and metabolic dysfunction. We determined if basal HSP expression (HSP70, HSP60, HSP25) was impaired in sedentary or exercised rats following the onset of diet-induced obesity. Male Long-Evans rats (N=6-7/group) were assigned to a [...]

The article presents a model that describes the shear of atomic planes in crystalline solids by accounting for their electronic structure. Previous studies have shown that an isotropic distribution of valence electrons leads to a spherically symmetric interatomic potential, which affects the stability of the crystal lattice against small shear deformations. Under these conditions, lattice stability is largely determined by the crystal's surface layer. As a consequence, the resistance to atomic-plane shear exhibits [...]
