A 2005 study by Qiao D, et al., published in the journal of Toxicology and Applied Pharmacology demonstrates the potential benefits of Vitamin E in preventing the adverse affects of pesticides. Nicotine and chlorpyrifos (a common pesticide), are known to harm the developing brain. Both promote the formation of oxidative radicals. Interestingly nicotine is found to […]

Did you know that most exposure to hazardous pollutants occurs indoors? Major contributors include common fragranced consumer products such as air fresheners, cleaning chemicals, laundry supplies, and personal care products. The EPA considers most of these to be indoor air pollutants, yet there are no standards to protect the most sensitive individuals. This 2017 article […]

This study examines the prevalence and clinical characteristics of chemical intolerance in a sample of primary care clinic patients. A total of 400 patients were recruited from 2 family medicine clinic waiting rooms in San Antonio, Texas. Patients completed the validated Quick Environmental Exposure and Sensitivity Inventory (QEESI) to assess chemical intolerance Overall, 20.3% of […]

Up to one-third of the U.S. population reported being either “especially” or “unusually” intolerant to certain chemicals, with about 5% reporting physician-diagnosed chemical intolerance (CI). Dr. Claudia Miller and colleagues developed the Environmental Exposure and Sensitivity Inventory (EESI), a validated tool designed to assist researchers and clinicians in evaluating patients and populations for CI. In this study, Drs. Miller and Prihoda applied the EESI to five different population groups for comparison. Groups were CI patients (1) who did or (2) did not attribute onset of their illness to a specific exposure event, (3) patients with surgically implanted devices, (4) Gulf War veterans (GWV), and (5) controls. All of the exposure groups reported similar multi-system symptoms and new onset chemical, food and drug intolerances despite having different initiating exposures.

A new study published by Environmental Health Perspectives takes a look at the risks of chemical exposures to neuro-development. Many of the toxicants listed are the same ones linked to chemical intolerance and Toxicant-Induced Loss of Tolerance. Read the study.
