Our team at the Toxicant-Induced Loss of Tolerance (TILT) Research Program at UT Health San Antonio wanted to share this important external article:
“Over 300 Pesticides Identified in Contaminated Bee Pollen Around the World” from Beyond Pesticides.
The article, published in Trends in Analytical Chemistry, features the results of a literature review of scientific articles from the last 10 years, which together identify more than 300 pesticides in bee pollen.
“Bee pollen, often used as an edible dietary supplement, is not regulated for pesticide residues, which sparks concern for human exposure due to contamination with pesticides, heavy metals, metalloids and mycotoxins,” according to the article.
“This highlights the exposure of bees to these toxic chemicals and their degradation products, during foraging in croplands and gardens, which then transfer to bee-derived products such as bee pollen.”
Pesticide exposure is an important concern in development of chemical intolerance (CI) and TILT, said Dr. Claudia Miller, allergist/immunologist, professor emeritus, and leader of the TILT Program at UT Health San Antonio.
How can you find out if you have chemical intolerance?
Answer these three questions from the TILT Program on Chemical Intolerance:
- Do you feel sick when you are exposed to tobacco smoke, certain fragrances, nail polish/remover, engine exhaust, gasoline, air fresheners, pesticides, paint/thinner, fresh tar/asphalt, cleaning supplies, new carpet or furnishings? By sick, we mean: headache, difficulty thinking, difficulty breathing, weakness, dizziness, upset stomach, etc.
- Are you unable to tolerate or do you have adverse or allergic reactions to any drugs or medications (such as antibiotics, anesthetics, pain relievers, X-ray contrast dye, vaccines or birth control pills), or to an implant, prosthesis, contraceptive chemical or device, or other medical/surgical/dental material or procedure?
- Are you unable to tolerate or do you have adverse reactions to any foods such as dairy products, wheat, corn, eggs, caffeine, alcoholic beverages, or food additives (e.g., MSG, food dye)?
If you answer YES to any question, take the Quick Environmental Exposure and Sensitivity Inventory (QEESI) and share the results with your doctor!
