Green tea's catechins & Hashimoto's: Might Make Thyroid Problems Worse

Green Tea Might Make Thyroid Problems Worse

"
Because of the effect green tea's catechins may have on the thyroid, experts at Precision Nutrition, a nutrition- and exercise-coaching company, recommend that people with thyroid-based autoimmune disorders such as Hashimoto's syndrome, a type of hereditary hypothyroidism, avoid drinking green tea and taking any dietary supplements containing green tea extract. The catechins in green tea may cause an imbalance in their immune system's T cell and B cell antibody responses, possibly resulting in more severe thyroid disorder symptoms.
