Are there best foods that help with an underactive thyroid?
I have an underactive thyroid. Are there any foods that can help the thyroid work better?
Diet plays a significant role in proper thyroid function. To perform optimally our thyroid, just like the rest of our body depends upon the availability of certain raw materials or building blocks. The production of thyroid hormone for example requires tyrosine, an amino acid found in protein foods, omega 3 fats from cold water fish, and iodine, a mineral found in iodized salt, fish and sea vegetables like seaweed. The conversion of thyroid hormone to its active form then requires other nutrients including selenium, zinc, chromium, iron, B vitamins, vitamins A and D. It is also important to recognize those foods that may impair thyroid function. These foods contain substances called goitrogens, which when consumed in large amounts may interfere with the utilization of iodine by the thyroid gland. Fortunately cooking inactivates these goitrogens so they tend not to be problematic when consumed as part of a normal healthy diet. I have put together a chart below which provides a nice summary of my recommendations.
