Chemicals Used In Packaging, Carpets And Utensils (Telfon) Are Endocrine Disruptors

    Whenever a news articles contains the phrase "endocrine disruptor" most people automatically think of chemicals like BPA, BPS and other related plasticisers. BPA and its related chemicals are known thyroid antagonists, estrogen agonists and androgen antagonists. The material commonly known as Teflon has long been suspected to also affect a number of organs such as thyroid and gonads, but so far solid evidence for its disrupting effects was lacking. This new study found that the perfluoroalkyl chemicals (PFAS) used in Telfon, carpet manufacturing, packaging, household cleaning products, etc is an endocrine/thyroid/metabolic disruptor much like the BPA family of chemicals, and led to dramatically lowered resting metabolic rate. If that was not enough, previous studies found that exposure to PFAS even within the allowed limits leads to obesity, immune dysfunction, CVD, and of course cancer. Most of these studies, including the one on weight gain, were done on humans and that makes the findings so much more relevant.

    "...Chemicals used to make non-stick pots and pans, stain-resistant carpets, and food packaging may contribute to high levels of obesity by disrupting the body’s ability to burn calories, scientists say. Researchers at Harvard University examined the effects of compounds called perfluoroalkyl substances (PFASs), which have already raised concerns among some health experts after animal experiments and other studies linked them to cancer, high cholesterol and immune problems. In the latest work, Qi Sun, a nutritionist who specialises in the risk factors for diabetes, obesity, and cardiovascular disease, analysed records for 621 overweight and obese people who spent six months dieting. All were part of a clinical trial run in the 2000s to test the effectiveness of different types of diets." As expected, those on the trial lost weight – on average 6.4kg over the six months of the diet – and then regained nearly half of that in the following 18 months. But Sun found that those who gained the most weight after dieting had the highest blood levels of PFAS chemicals, with the effects more pronounced in women. According to a report in the journal Plos Medicine, women in the study with the highest PFAS levels re-gained about 2kg more than those with the lowest PFAS levels. The scientists went on to show that those with high levels of PFAS in their blood also burned calories more slowly than the rest, as measured by their resting metabolic rate. “These chemicals may lead to more rapid weight gain after dieting,” Sun told the Guardian. “It is very hard to avoid exposure to PFASs, but we should try to. It’s an increasing public health issue.”

    Interesting. Been trying to stay away from getting new, cushy furniture, and sticking to Amish-style wood furniture. And replacing carpets with something like wood flooring (though that's probably treated with something) or natural linoleum (Marmoleum).

    Did you see this? House cats are having an epidemic of "hyperthyroidism" and wasting, likely caused by similar disruptors (PBDEs).

    Oh wow, thanks! Had not seen this. I suspect it is not HYPER-thyroidism but probably simple wastage triggered by estrogenic chemicals.

    Thanks , interesting to know about carpets.

    But didnt ray said that teflon cookware are safe if its unchipped?

    Maybe he change his mind with these new data, or maybe unchipped intact teflon doesn't release that much chemicals to cause a problem?

    Do you think these are similar in nature to what they put on cloths bought at department stores? Whenever I buy new cloths I always wash them because they smell a certain way...

    lots of threads on this. I think the consensus was new pyrex (the older ones leached something IIRC). Problem is that its a pain to cook on. I think next best is zero nickel stainless (18/0), following by 304 stainless (18/8 or 18/10). Ceramic pans have a modified version of teflon.

    Thanks. Stainless steel pans are still a pain to use regularly too.

    I agree especially with fried eggs, until someone on the forum introduced me to pan seasoning. Basically the same as you would with an iron skillet, heat up the pan until super hot, add oil and let smoke, and then let pan cool. You now have a pseudo non stick pan. You just cant wash it with soap or you have to season it again

    Recently i've bought two pots by VISIONS - it is ceramic-glass. I use them for about two months and absolutely love them! They are transparent like ordinary glass and it is funny to see through the pot , what is going on inside there. I like that they can handle deffirent tempretures - so you can cook or freeze smth in it. So far so good.

    I sometimes wonder about the shrink wrap on meats. It sometimes smells kind of "perfume-y."

    What would be a rapid way to detox from these chemicals? Clearly weight loss was not enough.

    I think this unless the top coating is teflon. They claim it's Keronite though. Korea Buyers Guide

    It should specify that it is 100% ceramic and not just ceramic coated. The ceramic coated ones are metal on the bottom so they are easy to spot. Most of the cheap ceramic pans are coated and they don't last very long.
    100% ceramic may be ok like the xtrema brand.

    I thought it was enamel cookware that was reasonably safe if unchipped, and teflon was reasonably OK if not heated too hot - breathing teflon fumes being toxic? (Not from Peat.)
