findings from 42 published studies found that consuming a daily 400-1000 IU vitamin D supplement may
reduce an individual’s risk for acute respiratory infection by up to 30%. medRxiv, November 2020
Diet: Processed Fats and Sugars Increase Muscle Pain. Researchers observed that switching the diet of mice
to one rich in either highly processed sugars or fats led to increased excitability of the muscle nerves and
resulting muscle pain. The findings suggest that reducing the intake of highly processed foods may benefit
patients with muscle pain. Nutrients, October 2020
Exercise: Benefits of Strength Training. The American Cancer Society notes the following benefits for
strength training: increased muscle mass, stronger bones, improved joint flexibility, increased metabolism, and
improved balance. American Cancer Society, November 2020
Chiropractic: Dizziness? It Could Be the Neck. Dizziness can have a number of potential causes, but one that
often goes unidentified is dysfunction in the neck, particularly in the upper cervical spine. A recent article in the
Journal of Exercise Rehabilitation notes that once vestibular and cardiovascular pathologies have been ruled
out, patients with ongoing dizziness issues should be evaluated for cervical disorders. Doctors of chiropractic
are trained to evaluate the cervical spine and to restore normal motion using a combination of manual therapies
and specific exercise recommendations. Journal of Exercise Rehabilitation, October 2020
Mental Attitude: Disasters Increase Suicides. According to a new study, an individual’s risk for suicide can
increase up to 23% following a natural disaster, and the elevated suicide risk can persist for up to two years. The
findings reveal that more mental health resources are needed to address challenges that arise after a disaster and
that these services should be extended for a longer period of time following a disaster.

Diet: Omega-3 Fatty Acids May Improve Prognosis Following Heart Attack. Among a group of 944 consecutive
acute myocardial infarction patients, researchers observed that those with higher omega-3 fatty acid serum levels
were less likely to experience major adverse cardiovascular events, readmission for cardiovascular causes, or death
from any cause in the following three years. The findings suggest that a diet rich in omega-3 fatty acids may offer
cardioprotective benefits. Journal of the American College of Cardiology, November 2020
Exercise: Short Sleep May Impair Physical Function in Seniors. Grip strength is often used in scientific research
as an indicator of physical function/fitness. Assessments of 121 older adults revealed an association between sleep
duration and stronger grip strength. The findings suggest that strategies to improve sleep in seniors could lead to
improved physical function. Journal of Clinical Sleep Medicine, November 2020
Chiropractic: Forward Head Posture Linked to Chronic Headaches? A review of data from twelve published
studies found that chronic primary headache patients were more likely to exhibit forward head posture than
individuals without a history of headache. The findings suggest that abnormal cervical posture could play a role in
the headache process. Doctors of chiropractic are trained to identify forward head posture and prescribe corrective
exercises. Pain Medicine, October 2020
Mental Attitude: Pregnancy-Related ADHD Risk Factors… An analysis of data from 35 published studies
identified evidence that the following are associated with an elevated risk for attention-deficit/hyperactivity disorder
(ADHD) in children: maternal pre-pregnancy obesity; pre-eclampsia; smoking during pregnancy; and maternal
acetaminophen use during pregnancy. Lancet Psychiatry, November 2020
Wellness/Prevention: Uterine Fibroids Common for Women. Uterine fibroids are common noncancerous
growths that usually appear during childbearing years. Common signs and symptoms include heavy menstrual
bleeding, menstrual periods that last longer than a week, pelvic pressure or pain, frequent urination, difficulty
emptying the bladder, constipation, and back or leg pain. If you suffer from these symptoms you should contact your

corticosteroid usage by patients with asthma and an elevated risk for osteoporosis and serious bone fractures.
Thorax, October 2020
Diet: High Flavanol Diet May Lower Blood Pressure. Evaluations of health and diet data concerning over 25,000
adults revealed that those with the highest intake of flavanols—compounds found in many fruits and vegetables, as
well as wine, tea, and chocolate, that have antioxidant properties—had a blood pressure reading 2 to 4 mmHg lower
than those who consumed the lowest amount of flavanols. Scientific Reports, October 2020
Exercise: Exercising One Arm Can Benefit the Other. New research suggests that if an arm becomes
immobilized due to injury, it can lose up to 28% of its muscle mass within four weeks. However, a recent
experiment found that performing eccentric exercises with the opposite arm could significantly reduce muscle loss in
the affected extremity. Scandinavian Journal of Medicine and Sports Science, September 2020
Chiropractic: Spinal Pain in High School Students. Examinations of 273 teenagers revealed that about one in six
(16.12%) had spinal pain. Further analysis showed the following characteristics are associated with an elevated risk
for spinal pain in teens: physical inactivity, obesity, central adiposity, and misalignment of the lumbar spine. Doctors
of chiropractic often approach spinal pain in adolescents with a combination of manual therapies, specific exercises,
and healthy lifestyle advice. International Journal of Environmental Research and Public Health, October 2020
Mental Attitude: Healthcare Usage in Early Infancy May Signal Autism, ADHD Risk. A review of the
electronic health records of nearly 30,000 children revealed an association between an increased frequency of doctor
and hospital visits during the first year of life and a later diagnosis of either autism spectrum disorder or attentiondeficit/hyperactivity disorder (ADHD). Lead author Dr. Matthew Engelhard adds, “This study provides evidence that
children who develop autism and ADHD are on a different path from the beginning… We have known that children
with these diagnoses have more interactions with the healthcare system after they’ve been diagnosed, but this
indicates that distinctive patterns of utilization begin early in these children’s lives. This could provide an
opportunity to intervene sooner.” Scientific Reports, October 2020
Wellness/Prevention: Cancer Screenings May Encourage a Healthier Lifestyle. An analysis of data from five

Health Alert: Heated Tobacco May Pose Threat to Heart Health. Tobacco products that heat but do not burn
tobacco to release a tobacco-flavored vapor that contains nicotine are marketed as a substitute for e-cigarettes or
traditional cigarettes. An analysis of nearly 50 human and rodent studies showed that such inhalants were associated
with high blood pressure, reduced dilation of blood vessels, stiffening of arteries, increased heart rate, and reduced
heart function. American Journal of Physiology-Heart and Circulatory Physiology, October 2020
Diet: Vitamin D May Delay Frailty? Frailty is a condition characterized by weakness, slowness, physical
inactivity, self-reported exhaustion, and unintentional weight loss. Past research has shown that low vitamin D levels
are associated with an increased risk for frailty among older adults. In a recent study, researchers observed that mice
given a supplement to achieve and maintain vitamin D levels at the higher end of the healthy range were
significantly less likely to become frail than those with low vitamin D status. Nutrients, October 2020
Exercise: Physical Activity Is Important for Kids’ Bone Development. An examination of 804 preteens found
that engaging in 1.5 hours of moderate-to-vigorous physical activity each day is important for healthy bone
development. Journal of Bone and Mineral Research, July 2020
Chiropractic: Myofascial Release for Neck Pain. Tightness of the suboccipital muscles at the back of the skull is
often experienced by patients with chronic neck pain. A study that included 58 chronic neck pain patients found that
myofascial release therapy, a form of treatment provided by doctors of chiropractic, applied to the suboccipital
muscles is effective for reducing neck pain intensity and improving cervical mobility. Spine, November 2020
Mental Attitude: Mom’s Thyroid May Influence ADHD in Kids. An analysis of data concerning nearly 330,000
mother-child pairs revealed an association between low thyroid hormone levels during the first trimester of
pregnancy and up to a 28% greater risk for a diagnosis of attention-deficit/hyperactivity disorder (ADHD) in her
child. American Journal of Perinatology, October 2020
Wellness/Prevention: Sleep Helps Ease Effects of Trauma. The results from a recent animal study showed that
rats that increased sleep time following a traumatic experience were less likely to develop ongoing fear symptoms
than rats that either maintained their sleep schedule or slept less. Lead author Dr. William Vanderheyden concludes,
“Basically, our study has found that if you can improve sleep, you can improve function… This highlights that there
is a time-sensitive window when—if you intervene to improve sleep— you could potentially stave off the negative
effects of trauma.” Scientific Reports, October 2020

reports that during a recent four-year timeframe, 34% of individuals over the age of 65 received a potentially
inappropriate prescription, which increased their risk for a visit to the emergency room by 26% and hospital
admission by 17%. Journal of the American Geriatrics Society, October 2020
Diet: Western Diet May Impair Sense of Smell. The Western-style diet is characterized by high-fat and high-sugar
intake and has been linked to several adverse health outcomes. A recent study found that mice fed a Western-style
diet were more likely to experience impaired odor detection, odor-related learning, and olfactory memory than
rodents on a standard diet. ACS Chemical Neuroscience, October 2020
Exercise: Exercise Benefits Hypertensive Patients. Patients under treatment for high blood pressure who
participated in a twelve-week combined aerobic and resistance training exercise program experienced improvements
in systolic blood pressure and endothelial function, as well a reduction in biomarkers for low-grade inflammation.

teachers during middle school and high school. School Psychology, October 2020
Wellness/Prevention: Should Colon Cancer Screening Start at Age 45? Current guidelines recommend that
people aged 50 to 75 get screened for colon cancer, which prevents about 25 deaths per 1,000 screenings. However,
because the current data shows an increase in colon cancer cases among those aged 45 to 49 years, the United States
Prevention Services Task Force is considering a recommendation for starting colon cancer screening at age 45,
which could prevent at least one death for every 1,000 people screened.

Diet: Is There a Way to Prevent Celiac Disease in Children? The results of the Enquiring About Tolerance
(EAT) Study suggest that introducing gluten into a child’s diet at four months of age may mitigate their risk for
celiac disease. Lead author Dr. Gideon Lack writes, “This is the first study that provides evidence that early
introduction of significant amounts of wheat into a baby’s diet before six months of age may prevent the
development of celiac disease. This strategy may also have implications for other autoimmune diseases such as
Type 1 diabetes.” JAMA Pediatrics, September 2020
Exercise: Sports Good for the Brain. In a recent experiment, researchers observed that engaging in physical
activity resulted in improved performance on memory assessments. Scientific Reports, September 2020
Chiropractic: TMD Linked to Migraine Risk. Researchers reviewed data on 514,866 participants from a
national health screening cohort and identified an association between migraines and temporomandibular
disorder (TMD). The finding adds to a growing body of research suggesting that musculoskeletal disorders may
be either a cause or contributing factor for migraines and addressing such issues—with chiropractic care, for
example—may be necessary to achieve a successful treatment outcome. Diagnostics, September 2020
Mental Attitude: Low Vitamin D Status and Delirium. Delirium, or sudden onset of severe confusion, is
common among older adults following hospitalization. A study involving 351,320 seniors identified an
association between vitamin D deficiency and at least one episode of delirium over the following 14 years. The
researchers conclude, “Because low vitamin D levels are simple to detect and inexpensive and safe to correct,
an intervention trial to confirm these results is urgently needed.”

Mental Attitude: Money Worries Increase Risk of Suicide Among Those with ADHD. According to a new
study, adults with attention-deficit hyperactivity disorder (ADHD) are more likely to develop financial
difficulties, which places them at an elevated risk for suicide. Study co-author Dr. Theodore Beauchine notes,
“The impulsivity found in ADHD is predisposing to suicide. And if you have a lifetime of financial problems
that can lead to a sense of hopelessness… Hopelessness combined with impulsivity is a really bad combination
and may increase the risk of suicide.” Science Advances, September 2020
