The thyroid is an endocrine gland located in the anterior part of the neck, at the base of the throat. It plays an important role in the metabolic processes of the body. In particular, it releases two primordial hormones: triiodothyronine and thyroxine.
However, some substances, used more or less commonly, can interfere with the activity of this gland.
Here are 5 products in your home that affect your thyroid:
1. Non-stick frying pans
Perfluorooctanoic acid, or PFOA, is a chemical derivative used in the manufacture of Teflon, a material found in non-stick frying pans. The EPA had decided to phase out PFOA in its production process by 2015, but the problems caused by this substance would not be related exclusively to the product’s eco-sustainability. A study conducted by researchers at the University of Exeter and published in the journal Environmental Health Perspectives has demonstrated the link between the high presence of this substance in the blood and the significant risk of developing thyroid disease, especially in women. Although PFOA is only an emulsifier used in the production process of stoves and some people claim that it is not present in the final product , it is strongly advised not to use them to cook food. at high temperatures, and not to use scratched material.
2. Flame retardants
That probably does not tell you much, and yet these are substances with which we are in daily contact. Flame retardants, polybrominated diphenyl ether or PBDE, are chemical substances whose purpose is to avoid the combustion of a product. They are present in mobile phones, computers, televisions, but also in cushions, carpets and coffee machines. According to research from Yale University, however, there is a link between exposure to PBDEs and thyroid cancer. According to Dr. Yawei Zhang , an associate professor in the Yale Department of Science and Environmental Health, many studies have shown that PBDEs interfere with the production of essential thyroid hormones, endocrine gland problems (including the thyroid gland). , decreased fertility in women, reduced birth weight in newborns, and developmental problems in children.
3. The plastic
In addition to the need to reduce the consumption of plastic to reduce the harmful impact on the environment, we find inside this material disturbing chemicals that interfere with thyroid function. Plastic bottles and food containers would cause these substances to migrate to the solid or liquid foods contained therein. A large-scale study of the University of Michigan has shown a strong link between thyroid disorders and DEHP, a very common phthalate. Urine specimens with greater than 20% DEHP were associated with a 10% decrease in some thyroid hormones. On the other hand, urine specimens with less than 20% DEHCP did not cause such a dramatic decrease in thyroid hormone production.

4. The tap water
The problem is not the water itself, but the perchlorate it can contain. According to the Centers for Disease Control and Prevention (CDC), the human body is significantly exposed to this substance. Perchlorate is a by-product of fireworks or gasoline, but also of matches. Its dangerous nature comes from the fact that it inhibits the absorption of iodine. According to a study conducted by the CDC , there is a link between the level of perchlorate present in the body and the level of thyroid hormones. Its action makes it able to block the thyroid iodine receptors, causing hypothyroidism. Fortunately, its presence in tap water is generally very low.
5. Antibacterial products
Triclosan is a common substance in lotions, soap and toothpaste; it serves to multiply the antibacterial action. Several studies have recently shown the health hazard of this substance, to the extent that the state of Minnesota (USA) has banned its use . But that’s not all. It appears that this substance affects the endocrine system , disrupting the hormones of the thyroid and sex hormones.
