Goitrin & Thiocyanates
Goitrin is a substance found in plant foods, such as rutabaga and the seeds of cruciferous vegetables. Thiocyanates are formed when sulfur-containing vegetables are cut, chewed or crushed. They both weaken the enzyme thyroid peroxidase, making it more difficult for iodine and tyrosine to bind and form thyroid hormones. Goitrin weakens the binding, while thiocyanates compete with iodine to be absorbed by the thyroid, making less iodine available for the production of thyroid hormones.
