Health advocates have been busy banning various chemicals used in cleaning products and everyday items.<\/p>\nHealth advocates have been busy banning various chemicals used in cleaning products and everyday items.<\/p>\n
Instead, they recommend \u201chealthy\u201d alternatives.<\/p>\n
Except that these healthy alternatives cause hypothyroidism \u2014 that\u2019s according to a new study in the journal Environmental Science & Technology<\/em>.<\/p>\n That\u2019s exactly what happened with sodium p-perfluorous nonenoxybenzenesulfonate (or OBS), which replaced perfluorooctanesulfonate (or PFOS) after health concerns emerged about the safety of the latter.<\/p>\n PFOS is a \u201cforever chemical\u201d that is now widely banned.<\/p>\n But is OBS really safe as a substitute?<\/p>\n The authors of this study used two models to explore whether OBS could affect thyroid health \u2014 especially with long-term exposure to small amounts like those we might encounter in everyday life:<\/p>\n 2.\tIn a human model, thyroid cells grown in the lab were exposed to OBS to see how they would respond.\n<\/dd>\n<\/dl>\n They then used a powerful set of scientific tools known as multiomics (which looks at genes, proteins, and metabolic changes) to get a detailed picture of what was happening inside the cells and tissues.<\/p>\n What they discovered was concerning:<\/em><\/p>\n 2.\tIn the mice, the number of thyroid cells dropped, and the ones that remained showed abnormal function.<\/p>\n 3.\tIn human cells, OBS triggered a strange and newly discovered type of cell death called disulfidptosis, which damages cells by disrupting their internal chemistry.<\/p>\n 4.\tThe thyroid hormone production pathway was blocked in both mouse and human cells after OBS exposure.\n<\/dd>\n<\/dl>\n Unfortunately, these chemicals are very hard to avoid.<\/p>\n They tend to be in non-stick cookware, waterproof clothing, food packaging, and stain-resistant carpets and furniture.<\/p>\n So, you can reduce your exposure by avoiding products marketed as \u201cstain-resistant,\u201d \u201cwaterproof,\u201d or \u201cgrease-proof.\u201d<\/p>\n For example, use glass, stainless steel, or cast-iron cookware instead of non-stick pans.<\/p>\n Otherwise, check product labels and look for fluoro or perfluoro ingredients \u2014 especially in cleaning products, cosmetics, and food packaging.<\/p>\n But OBS is only a small part of the problem.<\/p>\n I\u2019ve helped hundreds (probably thousands) of people to heal their hypothyroidism.<\/p>\n And one of my tools has been to avoid everyday chemicals that cause hypothyroidism.<\/p>\n\n
