Iodine is an element that the body needs but cannot produce it on its own. So we need to get the necessary amount of iodine from our diet or through supplements. Since it is present in most foods it is not difficult to get more iodine in our diets.

In the late 1800s and early 1900s, goiters were widespread. This problem of an enlarged thyroid gland was eventually shown to diminish when people were treated with iodine. When the US government finally approved adding iodine to table salt, the condition became much less common. While the US Recommended Daily Allowance is 150mcg, this amount is basically the minimum amount of iodine necessary for preventing goiter. To insure healthy thyroid function, which is key in establishing a good metabolism and hormone production, higher doses can be necessary.

Iodine deficiency during pregnancy and early stages of life can cause adverse effects on the child’s brain development. In young children, an iodine deficiency can cause mental retardation, growth problems, as well as impair speech and hearing development.

Natural sources of iodine include seaweed, seafood, and food from plants grown near the ocean. It is no surprise that Japanese people ingest many times the United States Recommended Daily Allowance of iodine and that they have far less cases of hypothyroidism and breast, ovarian, and prostate cancers. By eating iodine rich foods and supplementing this important element, you can boost your metabolism to avoid excessive weight gain, diabetes, and multiple hormonal issues. Though it is safe to increase your iodine consumption to our recommended daily dose, it is important to be careful with substances that have a hormonal effect. For example, products that increase testosterone or estrogen should be avoided unless you first consult your doctor. When done in a safe manner, hormonal therapies can and do have positive effects.
