Because your body uses dietary iodine to make thyroid hormone, iodine deficiency can lead to hypothyroidism -- which slows down your metabolism -- and cause mental retardation in babies born to iodine-deficient mothers, according to the American Thyroid Association.hoto Credit Maria_Lapina/iStock/Getty Images. Eating seafood â especially fish â or seaweed is a good way to boost your dietary iodine intake. Three ounces of cod, fish sticks and shrimp provide 99, 54 and 35 micrograms of iodine, respectively, according to the Office of Dietary Supplements.
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.
