Vitamin C and Alzheimer’s Disease

Ascorbic acid (AA) is widely known as an antioxidant and an immune system-enhancing micronutrient. However, AA has other relevant roles to include halting telomere attrition, cell growth, disorganization of chromatin (“packages” and protects DNA in tight bundles), excessive release of inflammatory factors, in addition to prolonging lifespan (Monacelli, Acquarone, Giannotti, Borghi, & Nencioni, 2017). Such

Food Preparation, Processing, and Vitamin C Bioavailability

It is generally understood that regular intake of phytochemical-dense foods provides anti-oxidants, among other micronutrients, which maintain health and longevity. Vitamin C (VC), a micronutrient known for its anti-oxidant and immune-enhancing properties, can be found in many fruits and vegetables (Leong & Oey, 2012). However, food preparation and processing can compromise the levels ascorbate and

Glutathione, Selenium, and Reactive Oxygen Species

It is thought that reactive oxygen species (ROS) are involved in many disease states to include arthritis, cancer, cardiovascular disease, diabetes, and Alzheimer’s disease (Duthie, 2003; Stockler-Pintos, Mafra, Farage, Boaventura, & Cozzolino, 2010). As such, maintaining optimal levels of anti-oxidants are critical in managing the destructive nature of ROS. Glutathione peroxidase (GSH-PX) is an example

Antioxidants

Antioxidants are substrates, which serve to protect a cell’s DNA, lipid membranes, and proteins from reactive oxygen species (ROS) (Duthie, 2003). As such, optimal levels of antioxidants are paramount in maintaining an organism’s health, performance, and longevity. Furthermore, ensuring that said substrate is adequately recycled for continued use is equal relevance (Grooper, Smith, & Carr,

CoQ10, Genetic Mutations, and Statins

CoQ10 is a nutrient whose production tends to become down-regulated by two main sources: genetic mutations involved in its synthesis (a primary deficiency) and statins, which inhibit an enzyme (hydroxymethylglutaryl coenzyme A) involved in the development of CoQ10 (considered a secondary deficiency) (Potgieter, Pretorius, & Pepper, 2013). Secondary deficiency is a common side-affect amongst individuals

Exercise and “Hitting the Wall”

Movement is the product of many systems working together in a highly coordinated and harmonious fashion. Such systems include the sensorimotor, musculoskeletal, and energy systems (Page, Lardner, & Frank, 2010). When functioning optimally, the coalescence of such systems can produce meaningful and effective motions, such as running. Over time, however, fatigue is expressed as a

Determining Optimal Vitamin D3 Levels

Optimal vitamin D levels, as measured by 25-hydroxyvitamin D, remains to be somewhat equivocal, thereby affecting recommended oral doses of vitamin D3. Since research indicates the critical relationship of vitamin D to optimal health, it behooves one to consider the nuances and implications of recommending supplemental vitamin D to individuals. The following will explore the

Dynamic Pattern Theory and Post-Rehabilitation

Post-rehabilitation (PR) clients require diligent and scrupulous program design. Extensive weakness and deconditioning are common traits among the aforementioned populace. PR clients are often seeing a medical professional, or have been recently discharged. Their injuries are usually resolved, but they are often not ready for the rigors of daily activity or work related tasks. Thus,

Immune Function and Gut Microbiota

The digestive tract is an estimated 16-foot long system, which includes the upper digestive tract (oral cavity, esophagus, stomach) in addition to the lower digestive tract (small and large intestine) and accessory organs (pancreas, liver, gallbladder) (Grooper, Smith, & Carr, 2018). Residing within the lower digestive tract is a complex system of bacteria, fungi, viruses,

Hemochromatosis, Supplementation, and a Tale of Caution

Micronutrient supplementation falls within an industry that generates substantial sums of revenue; Dagerman (2012) noted that in 2009, the aforementioned industry generated 26.7 billion dollars with 1,000 new supplements entering the consumer market yearly, and more than 29,000 supplements available for purchase in total. With such an array of choices, and a lack of quality

Thyroid Hormone Regulation and Health

Metabolic processes, in addition to normal growth and development, are heavily influenced by the endocrine system; a group of organs, which release hormones directly into the bloodstream (Reisner & Reisner, 2017). Such endocrine glands include the pituitary, adrenal cortex, medulla, pancreas, kidneys, parathyroid, and thyroid. Aberrations in the performance and function of said glands can

Detoxification, Organic Acid Testing, and Glucarate

In recent posts, I have explored methods to improve individuals’ health through movement and nutrition protocols. Although such approaches are highly valuable, they do not account for another dimension known to affect homeostasis; environmental exposures (EE). Once toxins enter the body, it is essential that they are eliminated as they can create aberrations in health

Benefits of Very Low Carbohydrate Ketogenic Diets

Americans consume approximately 55% of daily calories from carbohydrates that can include refined sources and simple sugars (Abbasi, 2018). Very low carbohydrate ketogenic diets (VLCKDs) can be defined as 20-50 grams of carbohydrates per day with, or without, the presence of ketosis (Feinman et al., 2015). Said dietary approaches have been explored, in addition to

The Elderly: Optimal Protein Sources and Consumption

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

Assessing Health Through Protein Status

In 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

MyFitnessPal Diet Analysis; Strengths and Limitations

Modern Western diets have experienced a drastic change compared to civilizations of 10,000 years ago (Ilich, Kelly, Kim, & Spicer, 2014). Today, approximately 70% of total energy emanates from refined vegetable oils, processed foods, sugars, and alcohol (Ilich et al., 2014). Such an aberration in nutrition quality over a relatively short period in human history

Crohn’s Disease, Vitamin D, and Single Nucleotide Polymorphisms

Research has indicated that individuals with Crohn’s disease (CD) can benefit from vitamin D3 supplementation (Carvalho et al., 2013). However, single nucleotide polymorphisms (SNPs) can blunt the anti-inflammatory properties of said vitamin. Such phenotypic variability makes one question the efficacy of recommending vitamin D3 supplementation without first considering potential roadblocks to absorption and utilization. The

Where Does Kinesiology Fit?

Where does Kinesiology fit? I remember a powerful article I read by Ives and Knudson (2007), indicating what they considered important components to a well-rounded academic program in exercise science. They argued, persuasively, that a good program was composed of several sub-disciplines (i.e., exercise physiology, biomechanics, functional anatomy, motor learning). The point that resonated, and
