Surprise Results with Chiropractic and the Great Flu Pandemic of 1917-18 

RVAchironeuro • April 6, 2020

Hello everyone:

In the closing days of World War I, a deadly form of influenza (“flu”) appeared. The influenza pandemic of 1917-1918 claimed more lives than the war.

During this crisis, doctors of chiropractic noticed that their patients seemed to have a lower fatality rate than the general population. Although this chiropractic observation remains unpublished in the peer-reviewed literature (since no scholarly journals were willing to publish chiropractic data in those days), a study was published by the osteopathic profession. 1  Among doctors of osteopathy of the time, it was routine to check patients’ spines for “osteopathic lesions” (what we know as “subluxations”), and to correct them with manipulation. Due to this similarity, the osteopathic publication effectively verifies the chiropractic experience.

The death rate among influenza patients under conventional medical care in the U.S. was estimated at 5 percent to 6 percent. The fatality rate among influenza cases under osteopathic care was estimated at 0.25 percent. The implication drawn from this data by the study’s author was that lesions (subluxations) depress the immune system; therefore, correcting the lesions assists immune function.

This conclusion, drawn by both osteopaths and chiropractors more than 80 years ago, has received support from recent research. The activity of the immune system’s major “players” – the white blood cells – has been found to increase after chiropractic adjustments. 2,3  A small, but intriguing study suggests that the immune response of HIV-positive patients (as measured by CD4 count) improves when spinal subluxations are corrected. 4,5

In your ordinary, day-to-day experiences, you are not likely to notice that your white blood cells are a bit sluggish. However, this may very well be one effect of spinal subluxation – even in the absence of a sore back or a stiff neck. If you are not already doing so, please consider scheduling monthly chiropractic check-ups, even if you are pain-free as this is another great reason to be well adjusted!!

Health News Update: How To Fight Inflammation and Chronic Disease 3.23.26 Hello again everyone: You might wonder why I keep focusing on food…so here are some of the reasons: food choices are the leading cause of death in the U.S. and spreading around the world. Poor food choices lead to inflammation which slowly destroy health. It is that simple, plain, and clear and backed by research. The next question: how do we fight back? Introduction The positive impact of food on health was postulated by the ancient Hippocrates, father of modern medicine with his famous quote: “Let food be thy medicine and medicine be thy food” [1]. In the 21st century, scientists have focused on the effect of nutritional habits in diseases. Nowadays, it is well documented that food plays a noteworthy role in the pathogenesis of chronic diseases namely cardiovascular diseases (CVD), metabolic syndrome, diabetes mellitus type II, and cancer [2–5], as it correlates with others with the lipid pattern, the blood pressure, and the endothelial function. The scientists examine the effect of nutritional habits on disease emergence and progression in both individual nutrient intake and dietary patterns models. Worldwide, two dietary patterns are usually compared—the Mediterranean diet (MD) and the Western diet (WD) [3,6]. The Mediterranean diet reflects the food culture of most Mediterranean countries based on olive oil consumption, seasonal fresh vegetables, cereals, and plants in balance with low consumption of meat [7]. The Western diet, on the contrary, is dominated by high-fat dairy products processed and red meat [8]. However, discordance in the different MD patterns and consumed food doses had been recognized. Without any doubt, those discrepancies could confine and restrict our knowledge on the health benefit mechanisms of the MD [9]. Due to the above, the medical community along with nutritionists and dieticians take a keen interest in MD and its traits [7]. https://www.academia.edu/45378994/biomedicines_Mediterranean_Diet_as_a_Tool_to_Combat_Inflammation_and_Chronic_Diseases_An_Overview?email_work_card=view-paper food choices can fight inflammation and chronic disease Bottom Line: This is a 2020 paper and since then literally hundreds of papers on the MD have emerged showing how the food plan lowers inflammation and the risk for developing multiple chronic illnesses. Even still, lots of research needs to be done to elucidate the many mechanisms of how food impacts our system and how to optimally individualize dietary recommendations. At this point, our best strategy to prevent and/or recover from any chronic condition is to eat as clean and natural as possible. It has become rather obvious that the further away from a natural diet we get, the sicker we become. On top of that, I have yet to see a full recovery from any health issue without the foundation of a predominantly plant-based, unprocessed, whole foods approach…which is why I keep posting about this subject. All the best to you and yours!
