Gastroesophageal Reflux and Nutrition

Gastroesophageal reflux disease (GERD) is a common condition affecting as much as 48% of Westernized countries (Ebrahimi-Mameghani, Sabour, Khoshbaten, Arefhosseini, & Saghafi-Asl, 2017). Such a health problem, left unmanaged, can lead to and produce other conditions such as gastrointestinal bleeding and esophageal stricture (narrowing). Thus, detection and management of said condition is paramount. As a […]

Hypochlorhydria and Dysbiosis

In this author’s last post, low stomach acidity (high pH), micronutrient maldigestion/malabsorption, causes/symptoms of high pH, and solutions to mitigate such conditions were considered. However, low stomach acidity can induce systemic affects where other physiological disruptions occur along the gastrointestinal (GI) tract, to include gut dysbiosis (Pizzorno & Katzinger, 2012). As such, the following will […]

Micronutrient Digestion/Absorption: The Critical Need for Optimal Stomach Acidity

Optimal gastrointestinal (GI) digestion and absorption processes are essential in providing cells and tissues with usable forms of micronutrients. When functioning properly, the GI tract participates in maintaining and protecting health, performance, and longevity. However, when dysregulated, such a system can negatively affect homeostasis. One pathophysiological manifestation of the GI tract, known as hypochlorhydria (low […]

Inflammation, Coronary Artery Disease, and Omega-3 Fatty Acids

Sears (2017) stated that heart disease, among other maladies, is a condition driven by inflammation. Sources of inflammation are widespread to include environmental (i.e., heavy metal exposure), lifestyle (i.e., sleep deprivation and stress), and nutrition (omega-6 rich processed foods) factors (Ilich, Kelly, Kim, & Spicer, 2014; Irwin, Olmstead, & Carroll, 2016; Umamaheswaran, Dasari, Yang, Lutgendorf, […]

Saunas, Detoxification, and Managing Cardiovascular Disease

Cardiovascular disease (CVD) is a condition accounting for 30% of all cause mortality and 10% disability worldwide (Zhang & Chang, 2019). Underlying causes of CVD can include congenital abnormalities, infectious agents, nutritional, and environmental factors (Reisner & Reisner, 2017; Sears, Kerr, & Bray, 2012). As such, interventions to manage said factors are paramount in maintaining […]

Lipid Oxidation Despite Presence of Adequate Antioxidants

Lipids may still become oxidized despite sufficient serum levels of CoQ10, vitamin E/A, and beta-carotene. Serum levels indicate the presence of said micronutrients, not necessarily the activity and/or proper form of the same. For example, vitamin A (retinol) levels can be within normal ranges, but if retinol-binding protein (RBP) is low (transports retinol), retinol will not […]

Cannabis and Sleep

Canada has now legalized the sale and use of cannabis. As time passes and proper education and public awareness is provided regarding medical application, some individuals may consider using said plant derivatives to mitigate the effects of insomnia. It is possible that, in conjunction to addressing micronutrient deficiencies and improving sleep hygiene (developing a consistent […]

Environmental Pollutants, Sweating, and Detoxification

Sears, Kerr, and Bray (2012) indicated that several elements exist in the environment that provide no known benefit, physiologically. Such elements include arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) (Sears et al., 2012). However, said elements have the capacity to bioaccumulate in the body producing aberrations in multiple regions to include the cardiovascular, […]

Boron: Food Sources and Function

Boron (B) is a substance once used as a preservative in foods (i.e., 50 years ago) thought to be a beneficial element, but is currently not considered essential to the human diet (Gropper et al., 2018). Although B is not essential, said micronutrient does exert influence over selected physiological processes to include bone development, mediation […]
