I have thyroid disease and I stopped taking the medicine a year ago, a decision I made on my own thinking I can cure myself eating naturally. This wasn't a very good decision and now I am back taking the medicine again. However, I am doing a lot of research and found this information from Andrea Beaman. Thyroids are so vital for your energy and overall health. So, check this out. I eat a lot of soy, almost all the cruciferous vegetables (see below for the list) and no yogurt or miso. Instead I should have I wish I knew this before!
"Foods that can contribute to enhanced thyroid health include natural unrefined, non-iodized sea salt. Sea salt contains an abundance of minerals and trace minerals imperative to overall health. "Iodized salt" (common table salt) focuses solely on iodine and neglects the balancing minerals and trace minerals, and can disrupt the body's natural process of absorption.
Sea vegetables can benefit the thyroid because they contain high concentrations of calcium, iron, phosphorous, potassium, sodium, zinc, magnesium, copper, chromium, vitamin A, vitamin B1, B2, B3, B6, manganese, iodine and more.
The thyroid takes in iodine and combines with tyrosine (amino acid) and is converted to T3 & T4. A lack of tyrosine can lead to depression. Natural sources of tyrosine include meat, fish, wheat, oats, almonds, lima beans, pumpkin and sesame seeds, and fermented foods like miso and yogurt.
Some common "healthy" foods can contribute to thyroid dysfunction. For example, goitrogens inhibit the body's ability to use iodine, promote goiter formation and act like anti-thyroid drugs. Foods from the Brassicacae family (cruciferous vegetables) and others, contain these goitrogenic compounds: broccoli, cabbage, kale, collard greens, mustard greens, cauliflower, watercreass, brussels sprouts, radishes, turnips, bok choy, arugula, daikon and rutabaga. Goitrogens are deactivated by HEAT. These specific foods needs to be COOKED (most often).
Fermented soybean products, a healthy staple (in small quantities) in many Asian cultures, include tempeh, miso, shoyu, natto and tamari. In America we've mass produced the soybean without properly fermenting it to release the antinutrients contained within, and it has become an unhealthy "health" food. Improperly processed soy products have been linked with thyroid disease, digestive disorders and many other illnesses."
