Thyroid disorders are quite common today and hormone replacement is the therapy that is recommended most often. For some time now, we have known that iodine is responsible for optimal thyroid function. However, being the complex gland that it is, the thyroid gland requires a complex set of nutrients and processes to fall in place to work effectively.
Find out some of these nutrients and their sources, as well as some herbs that help ease thyroid dysfunction.
1. Brazil Nuts
Thyroxine (T4) is the hormone produced by the thyroid gland. Triiodothyronine (T3) is what acts on metabolism. Conversion of T4 to T3 is a carefully regulated process that needs selenium to work.1
Brazil nuts are an excellent source of selenium, often pitched as being better than a selenium supplement. Not having enough selenium can interrupt the T4 to T3 conversion and cause hypothyroid-like symptoms.2
For so long now, cabbages, broccoli, cauliflower and other members of the cruciferous family have gotten a bad rep with thyroid. However, there is little to no indication that they are harmful and studies simply indicate a potential to reduce iodine levels in the body.
So, eat cruciferous by all means. They can prevent oxidative damage in the body, thyroid gland included. Just ensure that you get a bit more iodine than usual.3
4. Maca Root
If you’re asking what maca is, we don’t blame you. It is a root native to Peru and only available widely as a supplement. Several studies have pointed to the use of this supplement to reduce dependence on hormone replacement. Thyroid function is specially regulated very well by using a maca root supplement.5 Consult your doctor for dosage advice.
After seaweed, dairy products are abundant in iodine. As we know now, iodine in adequate amounts is responsible for thyroid function and producing thyroxine. By getting your daily dose of milk, yogurt, and other milk products, you can easily keep iodine-deficiency related hypothyroidism at bay.6
6. Fermented Foods
7. Clean Water
Do you know your source of water well? Studies have shown that consuming water with excess fluoride in it reduces the plasma T4 levels by over 75%!8 Most cities provide access to reports on water being supplied for drinking. Evaluate if the fluoride levels are deemed too high and ensure access to fresh, clean water.
