title: Focus on nutrition: the role of iodine in nutrition and metabolism.
abstract: Iodine, which forms part of thyroid hormone, is essential for sustaining life in vertebrate animals. An absolute iodine requirement is difficult to determine because of adaptive responses to varying iodine intake. Excess or deficient iodine intake may result in altered thyroid metabolism. The magnitude and direction of the response to changes in dietary intake may also depend on previous iodine intake. Therefore, an understanding of the distribution, absorption, and metabolic fate of iodine is integral to the investigation of the role of iodine in disease states.
