I wanted a post where I can put stuff related to 2 chemicals that I think people should stay away from BPA and Phthalates.
How to Avoid Phthalates
Phthalates are used in a wide range of common products and are easily released into the environment.
To avoid Phthalates:
- Stop microwaving food in plastics,
- Avoid scented products as much as possible, including air fresheners, and dryer sheets,
- Stop using recyclable plastics labeled as 3, 6, or 7.
Diet is believed to be the main source of di(2-ethylhexyl) phthalate (DEHP) and other phthalates in the general population.
Fatty foods such as milk, butter, and meats are a major source. In studies of rodents exposed to certain phthalates, high doses have been shown to change hormone levels and cause birth defects. (R)
DnBP and DiBP are found in a wide variety of consumer products, from dryer sheets to vinyl fabrics to personal care products like lipstick, hair spray, and nail polish, even some soaps. (R)
Pregnant mothers exposed to phthalate had kids with 6.6-7.6 lower IQ points.
“Researchers followed 328 New York City women and their children from low-income communities. They assessed the women’s exposure to four phthalates—DnBP, DiBP, di-2-ethylhexyl phthalate, and diethyl phthalate—in the third trimester of pregnancy by measuring levels of the chemicals’ metabolites in urine. Children were given IQ tests at age 7.
Children of mothers exposed during pregnancy to the highest 25 percent of concentrations of DnBP and DiBP had IQs 6.6 and 7.6 points lower, respectively, than children of mothers exposed to the lowest 25 percent of concentrations after controlling for factors like maternal IQ, maternal education, and quality of the home environment that are known to influence child IQ scores. The association was also seen for specific aspects of IQ, such as perceptual reasoning, working memory, and processing speed. The researchers found no associations between the other two phthalates and child IQ.
The range of phthalate metabolite exposures measured in the mothers was not unusual: it was within what the Centers for Disease Control and Prevention observed in a national sample.
“Pregnant women across the United States are exposed to phthalates almost daily, many at levels similar to those that we found were associated with substantial reductions in the IQ of children,” says lead author Pam Factor-Litvak, Ph.D., associate professor of Epidemiology at the Mailman School.
“The magnitude of these IQ differences is troubling,” says senior author Robin Whyatt, DrPH, Professor of Environmental Health Sciences and deputy director of the Columbia Center for Children’s Environmental Health at the Mailman School. “A six- or seven-point decline in IQ may have substantial consequences for academic achievement and occupational potential.”
“While there has been some regulation to ban phthalates from toys of young children,” adds Dr. Factor-Litvak, “there is no legislation governing exposure during pregnancy, which is likely the most sensitive period for brain development. Indeed, phthalates are not required to be on product labeling.”
While avoiding all phthalates in the United States is for now impossible, the researchers recommend that pregnant women take steps to limit exposure by not microwaving food in plastics, avoiding scented products as much as possible, including air fresheners, and dryer sheets, and not using recyclable plastics labeled as 3, 6, or 7.
The findings build on earlier, similar observations by the researchers of associations between prenatal exposure to DnBP and DiBP and children’s cognitive and motor development and behavior at age 3. This September, they reported a link between prenatal exposure to phthalates and risk for childhood asthma.
It’s not known how phthalates affect child health. However, numerous studies show that they disrupt the actions of hormones, including testosterone and thyroid hormone. Inflammation and oxidative stress may also play a role.” (R)
Be Wary of BPA: It Can Increase Blood Pressure
I tend to think people place more importance on many chemicals in relation to our health.
I’m skeptical of science’s ability to provide strong evidence for or against the harms of a chemical in the short term. Evidence for harm usually starts out as theoretical and then eventually long term clinical trials are done.
With that said, we are forced to choose between consuming some chemical or not and if the best evidence is theoretical, then that’s what we should go with.
I’m personally more scared/affected by natural toxins (lectins) found in food than the synthetic ones we add.
However, some toxins are more damaging than others. I’d say BPA is one of the more harmful ones. I try to not drink from plastic bottles or cans that have BPA.
Anyway, in recent study drinking from cans led to urinary BPA concentration increase of 1,600%.
I’ve come across many other studies showing BPA affects the body in many other ways.
Health Tools I Wish I Had When I Was Sick
At SelfHacked, it’s our goal to offer our readers all the tools possible to get optimally healthy. When I was struggling with chronic health issues I felt stuck because I didn’t have any tools to help me get better. I had to spend literally thousands of hours trying to read through studies on pubmed to figure out how the body worked and how to fix it.
That’s why I decided to create tools that will help others cut down the guesswork:
- Lab Test Analyzer – a software tool that will analyze your labs and tell you what the optimal values are for each marker — as well as provide you with actionable tips and personalized health and lifestyle recommendations to help you get there.
- SelfDecode – a software tool that will help you analyze your genetic data from companies such as 23andme and ancestry. You will learn how your health is being impacted by your genes, and how to use this knowledge to your advantage.
- SelfHacked Secrets – an ebook where we examine and explain the biggest overlooked environmental factors that cause disease. This ebook is a great place to start your journey if you want to learn the essential steps to optimizing your health.
- SelfHacked Elimination Diet course – a video course that will help you figure out which diet works best for you
- Selfhacked Inflammation course – a video course on inflammation and how to bring it down
- Biohacking insomnia – an ebook on how to get great sleep
- Lectin Avoidance Cookbook – an e-cookbook for people with food sensitivities
- BrainGauge – a device that detects subtle brain changes and allows you to test what’s working for you
- SelfHacked VIP – an area where you can ask me (Joe) questions about health topics
