According to the American Thyroid Association, one in eight women will be affected by thyroid disease in her life time. Since common symptoms of an underactive thyroid include weight gain and exhaustion, it’s easy to ignore these symptoms -- especially as we get older. The result? The illness goes undiagnosed – and untreated. This is a growing problem since thyroid disease is on the rise.
Why are so many Americans affected by thyroid disease? Recent studies have linked chemicals in our environment to the high rate. For example, a study at the University of Exeter and Peninsula Medical School connected the disease to perfluorooctanoic acid, which is a chemical compound used to make nonstick products like Teflon as well as stain-resistant fabrics. Also linked thyroid disease: bromide, an additive found in foods such as breads, certain sodas and sports drinks as well as flame retardants in mattresses, car interiors, carpets and fabrics. The substance can also be found in toothpaste, mouthwash, and some asthma inhalers.
Surprisingly, soy might also be a problem. Unfermented soy has been linked to thyroid disease because it’s an endocrine disruptor. This means it blocks thyroid hormone production, and eating it can affect the functioning of your thyroid.
