Health Alert: Plastic Chemical Linked to Nearly 1 in 13 Preterm Births.
Di(2-ethylhexyl) phthalate (DEHP) is a chemical commonly added to plastics to increase flexibility. However, when heated, flexed, worn down, or exposed to oils or solvents, it can leach into surrounding materials and enter the body through inhalation, ingestion, or skin contact where it may interfere with endocrine and reproductive function. A recent study estimated that about 8% of preterm births may be associated with DEHP exposure, highlighting the need for broader regulation of plastic chemicals to reduce health risks, particularly for pregnant women and infants.
eClinicalMedicine, March 2026

Diet: Repeating Meals May Aid Weight Loss.
For individuals in a weight loss intervention, researchers found that participants who maintained a stable daily calorie intake by repeatedly consuming the same meals lost more weight—5.9% of body weight versus 4.3%—over a twelve-week period than those with a more varied diet.
Health Psychology, April 2026

Exercise: High-Intensity Training Reduces Sarcopenia Risk.
High-intensity interval training (HIIT) combines short bursts of near-maximal effort with periods of moderate recovery. Using data from the Generation 100 Study, researchers found that seniors who engaged in a HIIT intervention cut their risk of developing sarcopenia in half over a five-year period. Sarcopenia is characterized by age-related loss of skeletal muscle mass, affects approximately 12% of older adults, and is associated with reduced independence and a higher risk of mortality.

Health Alert: Six Cancers Increasingly Affecting Adults Under Age 50.
New research suggests that at least six cancers—colorectal, cervical, pancreatic, prostate, kidney, and multiple myeloma—are occurring at increasing rates globally among people under age 50. Investigators attribute this rise to population-wide increases in obesity, pro-inflammatory dietary patterns, and physical inactivity.

Diet: Fiber Supports Brain Health Too.
Butyrate is a short-chain fatty acid produced when gut bacteria ferment dietary fiber. In addition to supporting intestinal health, it can also help reduce inflammation that affects the brain and nervous system. In a recent animal study, rats fed a fiber-free diet showed impaired activity in the amygdala—a brain region involved in fear and emotional memory—suggesting that adequate fiber intake may play an important role in brain health.

Chiropractic: Scapular Dyskinesis May Contribute to Neck Pain.
Among a group of 83 office workers with chronic neck pain, researchers observed that scapular dyskinesis—abnormal positioning or movement of the shoulder blade—was associated with greater neck disability. The findings suggest that altered shoulder mechanics may contribute to neck pain and functional limitation.
BMC Musculoskeletal Disorders, March 2026

Mental Attitude: Post-Seizure Brain State May Offer Critical Treatment Window.
According to a recent study, the brain enters a deep sleep state after a seizure that resembles memory consolidation, inadvertently strengthening seizure-related neural pathways. Researchers suggest this post-seizure period may provide a critical window for interventions—such as neuromodulation or adaptive brain stimulation—to disrupt this reinforcement and potentially reduce the risk of future seizures.
Journal of Neuroscience, February 2026

Wellness/Prevention: Several Health Conditions Linked to Alzheimer’s Risk.
Vanderbilt University Medical Center researchers analyzed health histories of more than 450,000 adults and found that individuals later diagnosed with Alzheimer’s disease were more likely to have developed a range of mental health, neurologic, sleep-related, cardiovascular, and endocrine/metabolic conditions in the preceding decade. The findings may help researchers develop tools to identify individuals at increased risk for Alzheimer’s disease, potentially enabling earlier interventions to delay or prevent the neurodegenerative disorder.

Health Alert: Binge Drinking Raises Mortality Risk in Adults Over Age 50.
Using data from the Canadian Community Health Survey, researchers report that binge drinking—defined as consuming five or more drinks within a few hours at least once per week—is associated with a 19% increased risk of death over the following decade among middle-aged and older adults. The authors conclude, “Targeted interventions and screening campaigns are needed to address binge drinking among older adults.”
Alcohol, March 2026

Diet: Inflammatory Diet May Promote High Blood Pressure.
A diet high in processed or fried foods, red or cured meat, sweets and sugary drinks, refined carbohydrates, and excessive alcohol intake has been linked to increased inflammation in the body. In an analysis of data from the Fasa Adult Cohort Study, researchers found that individuals with a more inflammatory dietary pattern had more than double the risk of developing hypertension over the following five years.

Chiropractic: Manual Therapy May Improve the Body’s Internal Balance System.
Proprioception is the body’s ability to sense the position and movement of its parts, contributing to coordination and balance. Because proprioceptors are concentrated in muscles, tendons, and joints, musculoskeletal injuries can disrupt their function, potentially impairing recovery and increasing the risk of secondary injuries due to altered biomechanics. An analysis of data from seven clinical trials found that the manipulative and mobilization therapies frequently used by chiropractors to restore joint movement may also help improve proprioception.

Health Alert: Women Face Higher Heart Risk at Lower Plaque Levels.
Atherosclerosis is characterized by the hardening and narrowing of the arteries, which can lead to potentially dangerous blockages if left untreated. A recent study found that a woman’s risk of heart attack or hospitalization for chest pain begins at a lower level of arterial blockage (20% vs. 28% in men), suggesting that standard risk thresholds may underestimate heart disease danger in women and support the need for sex-specific prevention guidelines.
Circulation: Cardiovascular Imaging, February 2026

Diet: Healthier Diet Linked to Lower Colorectal Cancer Risk.
A large international study that included nearly one million adults found that a diet pattern characterized by a high intake of fruit and vegetables (especially leafy greens), legumes, dairy, coffee, and tea, and lower consumption of red and processed meats and sugary drinks is associated with a lower risk of colorectal cancer.

Exercise: One Reason Too Much Sitting Is Unhealthy.
Serum osmolality is a measure of the concentration of dissolved particles in the liquid portion of the blood, reflecting the body’s fluid and electrolyte balance. Higher serum osmolality has been associated with poorer cardiovascular outcomes. A recent study found that as sitting time increases, so does serum osmolality—possibly due to reduced hydration, greater consumption of diuretic beverages, delayed bathroom breaks, and elevated blood sugar levels from snacking. The findings point to one potential mechanism by which prolonged sitting may negatively affect cardiometabolic health.

Health Alert: Hypertensive Pregnancy Complications Carry Lasting Health Risks.
It is estimated that up to 10% of pregnancies are complicated by hypertensive disorders of pregnancy, including chronic hypertension, gestational hypertension, preeclampsia, and chronic hypertension with superimposed preeclampsia—all of which can increase the risk of adverse outcomes for both mother and child. Despite evidence linking these conditions to a higher risk of future cardiovascular disease, chronic kidney disease, and metabolic syndrome, postpartum monitoring is often limited and adherence to interventions aimed at reducing long-term cardiometabolic risk remains low. Addressing these gaps could help improve long-term outcomes for women affected by hypertensive disorders of pregnancy.

Chiropractic: Upper Crossed Syndrome and Neck and Shoulder Pain…
Upper crossed syndrome is a postural imbalance characterized by tightness in the chest and upper neck muscles and weakness in the upper back and deep neck flexors, leading to forward head posture, rounded shoulders, and associated neck and shoulder pain. A recent narrative review reported that upper crossed syndrome may contribute to roughly two-thirds of neck pain cases and up to half of shoulder pain complaints among individuals who regularly use computers. If left unaddressed through ergonomic changes, lifestyle interventions, and conservative treatment approaches (such as chiropractic care), more serious conditions may develop, including nerve impingement, thoracic outlet syndrome, and cervicogenic headaches.

Diet: How a Ketogenic Diet Can Prevent Drug-Resistant Seizures.
The ketogenic diet is a high-fat, very low-carbohydrate eating plan that shifts the body’s metabolism into a state of ketosis, causing it to burn fat for fuel instead of carbohydrates. This dietary approach has long been associated with reduced seizure frequency in individuals with drug-resistant epilepsy, and a recent study may help explain why. Researchers at the University of Virginia report that increased levels of the ketone body β-hydroxybutyrate, triggered by ketosis, may help calm overactive brain cells by activating the HCAR2 receptor, which is present on seizure-related neurons and brain immune cells.
Annals of Neurology, November 2025

Exercise: Yoga May Have Role in Managing Common Musculoskeletal Disorders.
To support recovery and reduce the risk of recurrence, chiropractors often recommend that patients with musculoskeletal disorders engage in regular physical activity. A systematic review and meta-analysis of 52 clinical trials found that yoga is an effective exercise intervention for improving mobility and quality of life in individuals with musculoskeletal disorders, suggesting that regular practice may have a place in a multimodal treatment plan for back pain, neck pain, and other common musculoskeletal conditions.
