Re: chlorine as bad as bromine ?

still I don't understand...
fluoride comes first, chloride comes second, than bromide than iodide, so chloride is more reactive than bromide ?

Why does a very little quantity bromide replace Iodide in Iodide receptors in the thyroid for example ?

And very high quantity of chloride does much less harm?
I mean if you ingest some Seasalt than your chloride intake is probably 10 fold higher than your Iodide intake.

They are always talking about bromide in your thyroid gland, but width eating some Seasalt everyday your thyroid must be full of chloride... right ?

Do you know any scientific study which explains this ?
