Dementors drain âpeace, hope, and happiness out of the air around them,â according to Lupin (PA10). Even before a Dementor is seen, its presence is obvious; they are surrounded by an unnatural darkness and terrible icy cold (PA5). Dementors affect even Muggles, although the Muggles canât see the foul, black creatures. They were the guards at Azkaban and made that place horrible indeed.
The thyroid gland of a healthy adult concentrates 70-80% of a total body iodine content of 15-20 mg and utilizes about 80 Î¼g of iodine daily to synthesize thyroid hormones. In contrast, chronic iodine deficiency can result in a dramatic reduction of the iodine content in the thyroid well below 1 mg (1).
The US recommended daily intake of iodine is 150 micrograms (mcg) per day for most adults, and about twice that for pregnant and nursing women. This level of iodine intake prevents goiter, mental retardation, and all the associated problems with iodine deficiency.eâve already covered the issue of not getting enough iodine, but thereâs also another side to this coin: iodine is very dangerous if you get too much, especially when itâs taken as a supplement without the other nutrients that would naturally accompany iodine found in whole foods.
