Protein energy malnutrition (PEM) does affect the elderly population. The loss of skeletal muscle mass from inactivity and lack of food consumption can negatively affect performance and activities of daily living in said population (Lancha, Zanella, Tanabe, Andriamihaja, & Blachier, 2017). Furthermore, the loss of skeletal muscle can begin as early as the 4th decade of […]
Read MoreIn my last post, anthropometric assessments (body mass index, waist circumference, skinfold measurements, and bioelectrical impedance) were considered as a means of exploring an individual’s nutritional and health status. Although such measures are considered useful, biochemical tests provide another layer of screening designed to provide deeper objective and quantitative findings. Such biomarkers, in conjunction with […]
Read MoreIn my previous post, I outlined how hot and humid climates increase the rate of dehydration during exercise, as well as at rest. Although replenishment and maintenance of fluid balance is integral in maintaining homeostasis, content of fluids are of equal importance. During moderate to intense exercise, carbohydrates become a primary contributor to energy production […]
Read MoreOsteoporosis can be defined as decreased bone mass and a shift in the structure of bone, resulting in a reduced quality of bone (Tufts, 2011). The quality of bone cannot be assessed, however, bone mineral density (BMD) can be screened using dual energy X-ray absorptiometry (DXA) scans to determine mineral content of bone (Tufts, 2011). […]
Read MoreIron deficiency anemia (IDA) can be defined as a condition frequently marked by a low hemoglobin level (Brown, 2014). It is characterized by the signs of iron deficiency (depleted iron stores, weakness, fatigue, short attention span, poor appetite, weak immune system) in addition to paleness, exhaustion, and a rapid heart rate (Brown, 2014). Women with […]
Read MoreThere exists controversy between scientific literature and popular opinion regarding protein requirements for athletes (Phillips, Moore, & Tang, 2007). Some authorities recommend 0.8g/kg of bodyweight while others recommend as high as 1.7g/kg of bodyweight (Phillips et al., 2007). As a means of reconciling the aforementioned disparity, the following sections will explore the effects of ingesting […]
Read MoreIn my last post, I covered a brief history of Scotland and how they circumvented vitamin D deficiencies. The intent of providing a brief history of the Scots and vitamin D intake was to show the complex interplay of environment, physiology, cultural proclivities, and economics on the effects of health. It was also my intent […]
