Iodine is not only needed for healing wounds. This popular trace mineral is even essential for your internal health. Iodine occurs naturally in a large number of foods. Iodine supplementation are recommended for people suffering from iodine deficiency.
Importance of iodine foods
More than 60 percent of the iodine deposit in the body is used for regulating thyroid function. Iodine is an important component of the thyroid hormones. Deficiency of this trace mineral slows down the activities of the thyroid gland.
Iodine could even prevent fibrocystic breast disease.It can even lower the risk of breast cancer by slowing down the harmful effect of the estrogen hormone on the breast tissues.
Studies have shown that women suffering from breast cancer usually have low iodine reserve in their bodies. Iodine might even lower the risk of ovarian cancer. Pregnant women must consume adequate amount of iodine rich foods to reduce miscarriage risk. This trace mineral helps to strengthen your immune system.
Sources of Iodine
Sea vegetables and fish are the richest sources of iodine. Marine plants and animals build their iodine reserve by absorbing iodine from the seawater. Kelp, seaweed, shellfish and deep-water fish contain large amounts of iodine. Iodine is even present in leafy green vegetables especially spinach and turnip greens, squash, garlic, soy, sesame seeds and strawberries. Moderate amount of iodine is present in eggs, milk and dairy products. Iodized salt is a readily available source of iodine.
Recommended dietary allowance
Adult men and women need about 150 micrograms of iodine daily. Children up to 13 years of age might need slightly lesser amount of the trace mineral. Pregnant and lactating women require 220 micrograms of iodine per day.
Iodine overdose risks
Iodine overdose is as harmful as iodine deficiency. Excess intake of iodine, over 1 gram, causes nausea, vomiting, weakness, abdominal pain, diarrhea and burning sensation in the mouth, throat and abdomen.
Iodine overdose could be fatal for people suffering from tuberculosis and kidney diseases. It might even increase the risk of thyroid papillary cancer. In the worst case, iodine overdose leads to coma. Usually iodine overdose does not occur through intake of iodine rich foods.
