Iodine deficiency iodate as dough conditioner in bread and baked goods was gradually replaced by the use of other conditioning agents such as bromide. Iodine deficiency resulting in goiter occurs in 187 million people globally (2.7% of the population). It resulted in 2700 deaths in 2013 up from 2100 deaths in 1990. A low amount of thyroxine (one of the two thyroid hormones) in the blood, due to lack of dietary iodine to make it, gives rise to high levels of thyroid stimulating hormone (TSH), which stimulates the thyroid gland to increase many biochemical processes; the cellular growth and proliferation can result
Iodine value hand, linseed oil is highly unsaturated, which makes it a drying oil, well suited for making oil paints. This particular analysis is an example of iodometry. A solution of iodine is yellow/brown in color. When this is added to a solution to be tested, however, any chemical group (usually in this test C=C double bonds) that react with iodine effectively reduce the strength, or magnitude of the colour (by taking iodine out of solution). Thus the amount of iodine required to make a solution retain the characteristic yellow/brown colour can effectively be used to determine the amount of iodine sensitive
