Decide if the following premise is consistent with the corresponding hypothesis. Note that consistency means all information in the hypothesis is supported by the premise.

Premise: Iodized salt is salt that has been processed to contain relatively high levels of iodine. Iodine is an element that is essential for the proper functioning of the thyroid gland, and as a result, for proper bodily metabolism. The thyroid gland requires iodine to produce the thyroid hormones that control the metabolic rate of the body. Iodized salt is therefore used to prevent or treat iodine deficiency, which can result in decreased metabolism and even goiter, a swelling of the thyroid gland.
Hypothese: body simply eliminates excess iodine, and as a result, long-term supplementation with high doses of iodine has no additional effect once the body is replete with enough iodine. It is unknown if the thyroid gland is the rate-limiting factor in generating thyroid hormone from iodine and tyrosine, but assuming it is not, a short-term loading dose of one or two weeks at the tolerable upper intake level may quickly restore thyroid function in iodine-deficient patients. Iodine vapor is very irritating to the eye, to mucous membranes, and in the respiratory tract. Concentration of iodine in the air should not exceed 1 mg/m\u00b3 (eight-hour time-weighted average). When mixed with ammonia and water, elemental iodine forms nitrogen triiodide, which is extremely shock-sensitive and can explode unexpectedly.
