Iodine is an essential mineral that the body needs to produce thyroid hormones, which regulate the metabolism and function of an infant's bone and brain development. Therefore, this trace element is particularly important in pregnant women and infants. People with a deficiency of iodine fail to make sufficient amounts of thyroid hormone. This leads to health issues such as goiter, irregular metabolism, hypothyroidism and certain psychological disorders. "In pregnant women, severe iodine deficiency can permanently harm the fetus by causing stunted growth, intellectual disability, and delayed sexual development. Less severe iodine deficiency can cause lower-than-average IQ in infants and children and decrease adults' ability to work and think clearly," NIH said.How Much Of Iodine Do You Need? While everyone needs iodine, there is a particular amount of this mineral that everyone needs. For instance, adults need about 150 micrograms (mcg) a day. Infants need about 110 mcg a day up to 6 months old and 130 mcg from 7 to 12 months. Then recommended levels go down to 90 through 8 years of age. Kids 9 to 13 should get about 120 mcg per day. You will need more if you are pregnant or nursing. It is pertinent to note that most of the people get iodine from their food and seldom need supplements. Natural Sources Of Iodine Besides Table SaltWhile the ubiqutous iodized salt is something that is the most common source of iodine, there are other food items that can help you complete your iodine intake. Seafood (e.g., cod, tuna): Seafood is one of the best natural sources of iodine, as marine organisms absorb this mineral from seawater. Fish like cod and tuna are particularly high in iodine, making them excellent options for maintaining healthy thyroid function.Dairy (e.g., milk, cheese): Dairy products are also good sources of iodine, primarily due to the iodine content in the feed given to dairy cows. Regular consumption of milk, yoghurt, and cheese can help meet daily iodine needs.Eggs: Eggs are a nutritious source of iodine, mainly found in the yolk. They contribute to dietary iodine intake, especially when included as part of a balanced diet, supporting overall health and metabolic functions.Fruits and Vegetables: While fruits and vegetables generally contain less iodine than seafood or dairy, certain varieties—especially those grown in iodine-rich soils—can provide beneficial amounts. Seaweed, for example, is a notable exception, often delivering high levels of iodine.
