Iodine should be routinely added to complementary foods.

Iodine deficiency has major health consequences for the fetus and infant. Most individuals can tolerate fairly high intakes of iodine without problems. The Western Hemisphere has made great progress towards correcting its iodine deficiency, but pockets of deficiency remain and fragile monitoring systems endanger sustainability. Because the consequences of iodine deficiency are severe and the risks of excess treatment with modest supplements are minimal, we recommend the regular addition of 90 microg of iodine daily to complementary foods for children and 150 micro g for pregnant or lactating women, accompanied by effective monitoring of urinary iodine concentration in the population.
