Are broccoli sprouts harmful?

Broccoli sprouts are not harmful and have been shown to have beneficial effects. A three-month study on the continuous ingestion of sulforaphane from broccoli sprouts found no negative effects on thyroid function. Additionally, in an animal study, broccoli sprouts had a beneficial antioxidant effect on the thyroid gland, even in iodine-deficient animals 1. Therefore, the concerns about broccoli sprouts being harmful, particularly to thyroid health, are unsupported by scientific evidence.
