Foods that Suppress Iodine Uptake - Goitrogens , page 1

 

I thought I would make a short thread to inform people that some foods/elements/drugs can interfere with iodine absorption. Even if you don't plan on taking iodine supplements or eating sea foliage for when the radioactive particles may come, these are some foods you may not want to eat excessive amounts of until this blows ov... er, I mean away. Of course, this generally applies for when these foods are consumed raw, as cooking will inactivate the Goitrogens.

 

Did you know that there are certain foods which can affect your thyroid in a negative way?? They are commonly known as Goitrogenic foods, which means they contain substances which prevent your thyroid from getting its necessary amount of iodine. If eaten in excess, they interfere with the healthy function of your thyroid gland, tilting you in the direction of being even more hypothyroid, or making you susceptible to having a goiter, or enlargement of your thyroid. If you look closely at the word itself, you can see the root word is goiter (goitro-gen). Foods which you have to be careful with most revolve around soy-related products and ingredients, as well as certain cruciferous veggies, nuts and some fruits.

Goitrogenic drugs and chemicals Chemicals that have been shown to have goitrogenic effects include: * Sulfadimethoxine, propylthiouracil, potassium perchlorate, and iopanoic acid.[1] * Some oxazolidines such as goitrin.[2] * Thiocyanate overload in Central Africa, especially if also in conjunction with selenium deficiency.[3] Reliance on cassava as a carbohydrate provides a source of thiocyanate in some areas.[4] * Ions such as thiocyanate and perchlorate decrease iodide uptake by competitive inhibition and, as a consequence of reduced thyroxine and triiodothyronine secretion by the gland, cause an increased release of thyrotropin (by reduced negative feedback), which then stimulates the gland. * Amiodarone inhibits peripheral conversion of thyroxine to triiodothyronine; also interferes with thyroid hormone action. * Lithium inhibits thyroid hormone release. * Phenobarbitone, phenytoin, carbamazepine, rifampin induce metabolic degradation of T3 and T4. Goitrogenic foods Certain raw foods (cooking inactivates the goitrogens) have been identified as lightly goitrogenic. These foods include: * cassava * Soybeans (and soybean products such as tofu, soybean oil, soy flour, soy lecithin) * Pine nuts * Peanuts * Millet * Strawberries * Pears * Peaches * Spinach * Bamboo shoots * Sweet Potatoes * Vegetables in the genus Brassica [5] o Bok choy o Broccoli o Broccolini (Asparations) o Brussels sprouts o Cabbage o Canola o Cauliflower o Chinese cabbage o Choy sum o Collard greens o Horseradish o Kai-lan (Chinese broccoli) o Kale o Kohlrabi o Mizuna o Mustard greens o Radishes o Rapeseed (yu choy) o Rapini o Rutabagas o Tatsoi o Turnips Thyroid hyperplasia has been demonstrated in mice:[6] Despite being generally a stimulant, caffeine (examples: coffee, tea, cola, chocolate) acts on thyroid function as a suppressant.[7] Indeed some studies on rats suggest that excess caffeine in conjunction with a lack of iodine may promote the formation of thyroid cancers.[8] en.wikipedia.org...

Also, if you are still eating white bread made with bleached flour... stop doing it! The bromine used in the bleaching process can be taken up into the thyroid and cause dysfunction. Not to mention your bod will absorb all that tasty radioactive iodine to replace the bromine you acquired from that bread you thought was good for you.
