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 National Institute of Medicine has set Adequate Intake (AI) of iodine for infants: 0 to 6 months, 110 mcg/day; 7 to 12 months, 130 mcg/day. For children and adults, Recommended Dietary Amounts (RDA) have been set: children 1 to 8 years, 90 mcg/day; 9 to 13 years, 120 mcg/day; people age 14 and older, 150 mcg/day.
