There’s increasing evidence exposure to environmental chemicals poses a serious threat to thyroid health. Termed ‘thyroid disrupting chemicals’, these environmental toxins damage the thyroid, and interfere with day to day function of the thyroid hormones.
Furthermore, thyroid dysfunction due to exposure to thyroid disrupting chemicals can have a ripple effect on your entire endocrine system.
According to Dr. William Davis, Cardiologist, Author + Health Crusader
We are living in a dangerous era, a time when industrial compounds have proliferated to such an extraordinary degree that literally everyone is exposed to chemicals that cause some form of endocrine disruption.
Disruption can occur at the brain level (hypothalamus and pituitary that control the thyroid), at the thyroid gland level, or even at the level of tissues, such as fat cells, liver, and muscle, which are all dependent on thyroid hormones.
10 Of The Most Harmful Thyroid Disrupting Chemicals
Here is a list of the environmental chemicals that pose the biggest threat to thyroid health. There’s no doubt this list is a little daunting. But this gives you an idea of what we are all up against.
- pesticides found in the food and water supply.
- polychlorinated biphenyls (PCBs) found in older paints, electrical equipment and building materials
- heavy metals such as cadmium, lead and mercury. Mercury is routinely released from silver dental fillings especially in older fillings.
- dioxin and dioxin-like compounds from the environment.
- phthalates found in vinyl and plastic products.
- polybrominated diphenyl ethers (PBDEs) flame retardants present in carpets, clothing, soft furnishings, electronics and plastics.
- polycyclic aromatic hydrocarbons (PAHs) present in air pollution.
- bisphenol A (BPA) found in a variety of food and beverage packaging.
- bromides used in oils to stabilise citrus flavoured soft drinks, commercial bakery products, some flours and is also found in pesticides.
- halogens which include fluoride, chlorine, perchlorate and bromide. Halogens compete for the same receptor sites as iodine. Excessive intake of hazardous halogens blocks optimal iodine activity.
