Abstract Iodine is an essential microelement for human metabolism and growth. Current chemical textbooks are lack of basic introduction to knowledge of scientific iodine supplementation. Questionnaire survey found that most teachers and students do not have a complete understanding of scientific knowledge of iodine supplementation. Concluded from previous literatures, following points of iodine supplementation are essential: the recommended amount of iodine intake for adult is 120 μg·d-1; the maximum tolerable amount of intake is 600 μg·d-1; iodized salt should be consumed in iodine-deficient areas where water iodine is below 40 μg·L-1, while iodine-free salt is suggested for areas above 100 μg·L-1; people who regularly ingest iodine-rich food should cut back on iodized salt even in iodine-deficient areas. Therefore, advices on scientific iodine supplementation are put forward in the teaching process and textbook content, so as to improve teachers' and students' cognition level of iodine supplementation and cultivate students' ability to make correct value judgment on related hot social issues.
