I'd have to agree. I do know that this and a few others do influence thyroid, but that doe's not mean you have to avoid it totally. Moderation in all things is only sensible. By the way, broccolli is very porice and therefore absorbs an abundance of chemicals sprayed on the broccolli fields, so if you can get organic, it would be best.
Broccolli is also a great anti-oxident in preventive measures against cancer.
