Nutrient supplement; added to food as a source of iodine [DFC]
Potassium iodide is an inorganic compound with the chemical formula KI. The major uses of KI include use as a nutritional supplement in animal feeds and also the human diet. For the latter, it is the most common additive used to "iodize" table salt (a public health measure to prevent iodine deficiency in populations which get little seafood). Kelp is a natural KI source. The iodide content can range from 89 ug/g to 8165 ug/g in Asian varieties, making prepared foods content difficult to estimate. Eating 3-5 grams of most dried, unrinsed seaweeds will provide the 100-150 micrograms iodide recommended daily allowance for nutritional purposes. [Wikipedia]
