is eatting soy products harmful when you have hypothyroid

Soy's effect on thyroid was first noticed when hypothyroid babies were given soy formula, ad they became more severely hypothyroid. They were unable to overcome the anti-thyroid effects of soy, so I guess here is simple answer to your question. A report to this effect appeared in the New England Journal of Medicine in 1960, and since then many other small studies have confirmed that soy is a goitrogen. This means soy products contain a substance that can cause enlarged thyroid known as a goiter. Endocrinologists, thyroid specialists, are frequently unaware of the potential anti-thyroid effects of soy on hypothyroid women who are in menopause and are often eating a lot of soy. Recent research leaves little doubt that dietary isoflavones in soy have a profound effect on thyroid function. A study by Japanese researchers concluded that intake of soy by healthy adults for a long duration caused enlargement of the thyroid. Beside this effect, consummation of soy product leads to the suppressing thyroid function. These researchers studied the effects of feeding 30 g of soybeans per day on thyroid function and found that after one month there was a significant increase in thyroid stimulating hormone.

yes, manders, you best avoid soy and anything with soy in it; I know it's difficult to find, but if you check food labels carefully you can find what foods have soy and which do not...it does take a concerted effort.

studies have shown that soy inhibits thyroid function and also thyroid medications...and if you are hypo, then it spells trouble for your body.

I can tell you more if you wish
