In reading some blogs, I read that green tea can slow down the thyroid function. I already have hypothyroid for which I am taking Synthroid. Is green tea bad for me? I've just started drinking it due to reading
The goal of thyroid-replacement therapy is to restore your body to the place it would be if your own gland was working well and fulfilling all you entire hormone need. Since most thyroid-healthy people drink green tea without any problem at all, your goal should be to replace your thyroid hormones at the optimal levels that will allow you to be thyroid-healthy again. I have been optimally treated for several years now, and I eat/drink just about anything I want to without worrying about what it does to thyroid function.
FYI... It's said that green tea contains high levels of fluoride. Granted, fluoride is a potent thyroid-inhibitor. In fact, it was the first treatment developed for the treatment of hyperthyroidism, because it so effectly inhibits hormone production. But the amount of fluoride in green tea is chump change compared to the fluoride in your municipal water supply and/or dental products. So the question becomes... Are you willing to give up the green tea you enjoy, but not do anything about the other two that have a much greater effect on thyroid function?
Midwest is correct on this. So long as your thyroid levels are optimal, go ahead an enjoy your green tea. I have HT and I drink 1-2 cups of green tea everyday, and I can tell it does not affect how I feel and doesn't seem to affect my thyroid levels, either.
