Some people believe that the thyroid is the “heart” of the endocrine system. As one of the largest endocrine glands, it plays an important role in maintaining energy levels and secreting hormones—among other things. When the thyroid’s working properly, it’s business as usual. Unfortunately, nasty chemicals can play a huge role in problems.
The Dangers of Thyroid Toxins
Toxins are present in our environment, and there’s very little we can do to eliminate all of them. We can, however, limit our exposure to toxic compounds, reducing the likelihood of experiencing issues with our thyroid. Supplementing with iodine is also an important step toward protecting your thyroid from toxic compounds. Learn these 6 toxins that can destroy your thyroid so you can prepare yourself.
As an endocrine disruptor, BPA can affect hormone levels and throw thyroid function out of whack. While there are many studies documenting BPA’s effects on the thyroid in adults and children, a recent one took a different approach.  By looking at newborns and their mothers, the study suggested higher levels of BPA cause a decrease in thyroid function in women. All of the baby boys, though, had an increase in thyroid function from the higher levels of BPA.  The theory here is that the women—while pregnant—saw a drop in thyroid function and the sons’ thyroids overcompensated. While the trend did not carry over to newborn girls, avoiding BPA while pregnant just makes sense.
Bromine is toxic to the thyroid, but with it in everything from pool cleaner to pasta, finding something without the endocrine disruptor can be tricky.  Often, even healthy patients can have high levels of the flame-retardant substance in their bodies. Polybrominated diphenyl ethers (PBDEs) are even finding their way into the breast milk of American women.  One common source of bromine is brominated vegetable oil—which is still found in many drinks—so remember, it pays to read those labels!
Studies suggest low thyroid function in mothers is linked to neurodevelopmental problems in children. While BPA—as mentioned in number 1—or any score of nasty toxins could be the cause of an unhealthy thyroid, perchlorate is definitely one of the usual suspects.   But while there are numerous studies linking it with thyroid problems, the FDA still approved it for use as an anti-static agent in food packaging, making avoiding it a lot more difficult. 
When it comes to maintaining a healthy thyroid, avoiding pesticides could also be key. In India, thyroid disorders are on the rise, but there are measures in place to make sure much of the population has sufficient access to iodine, something essential for thyroid function. One recent study suggested this spike is due to pesticide and other chemical exposure, with experts noting almost 60 percent of cases aren’t connected to iodine-deficiency.  While the idea of pesticide exposure and thyroid problems is nothing new, maintaining iodine levels and avoiding pesticides could be the perfect combination. 
There’s a report that a higher level of perfluorinated chemicals (PFCs) in the blood could affect thyroid function in women.  Used in the manufacturing of lots of common things, PFCs can even be found in pizza boxes and takeout containers; your mattress might even contain them! Even though the use of the chemicals is being phased out in the U.S., imported products could still be a concern.  Endocrine disruptors like PFCs take a long time to break down in the body, so this study is disturbing, to say the least.
Almost 70 percent of the U.S. water supply is fluoridated to help prevent cavities. Many people don’t know, however, that fluoride was actually prescribed as a remedy for an overactive thyroid during the first half of the 20th century. According to some reports, 2 to 5 mg of fluoride per day over a period of months was all it took to lower thyroid function; this becomes a problem when you realize that’s about the same amount people drinking fluoridated water are exposed to daily. 
Some Other Tips to Think About
You want to make sure your thyroid is as healthy as possible, so make sure you’re aware of just what can be dangerous. To protect your health, be sure to eat foods that support thyroid health as much as you can. While your family history can also play a role in endocrine problems, avoiding toxic exposure is a smart way to go.
