Your body does not make iodine. Instead, you need to consume iodine in form of food or iodine supplements. If you donât have enough iodine in your body, known as an iodine deficiency, your body cannot make enough thyroid hormone and your thyroid becomes enlarged.This can lead to serious thyroid issues, as well as poor health overall.ost adults can get 100% of their daily intake of iodine by adding a total of just over 1/2 teaspoon of iodized table salt (approximately 3g) to their meals. 1  You can add iodized salt when you cook and bake. 2  You can also replace your salt shaker with iodized table salt.
When iodine is added to a starch, it adheres to the beta amylose molecules because of their solubility. The starch pushes the iodine into a line in the middle of the amylose coils and creates a transfer of charge between the iodine and starch. This causes a change in the arrangement of electrons and energy level spacings. The new spacings absorb visible light differently and create the deep blue color. Iodine is often used to test foods for starch. Adding iodine to potatoes, dried beans, rice, bread and pasta creates the deep blue reaction to indicate the presence of starch. To perform the test, use a dropper to add one or two drops of iodine to each type of food. Use other foods that do not contain starch, such as apple slices, carrots and sugar, for comparison.
