I was wondering if anybody had a fix on how much iodine is contained in those thin sheets of Nori/ Seaweed snacks they sell at Trader Joes and Whole Paycheck?
Here comes the math:
So you would have to eat about 24 nori snacks to get your RDI of iodine.
The link above says that 1/4 of an ounce of dried seaweed has 4500 mcg of iodine. I am looking at Kirkland seaweed snacks that I bought at costco. The package states that a 3.4-gram serving size is a fifth of a pack. A quarter of an ounce would be about 8 grams, so if the link is correct, somewhere around half a pack, or 2.5 servings, gives you 4500 mcg of iodine (and 50 calories). These are the Kirkland Signature Roasted Seasoned Seaweed Winter Harvest.
Iodine is essential element for immune system in fighting cancers. And it is almost diminished from our foods or replaced with bromide (in breads for example), whichis not good for your health. Bromides and fluorides are to avoid. I am a breast cancer survivor and like to snack on Kirkland's winter harvest seaweed from Costco. Even iodine in iodinized salt is not enough for DV% wee need.
Who cares if 10 M japanese people survive just fine? Would you say the same abotu sun exposure with blacks in Africa and Whites in Antartica? No? Well...
And again, what Thyroid Patient said is way more accurate and substantiated than these ludicrous claims. Their kids suffer from goiters too.. they have huge side effects from eating too much but like everywhere else, thyroid issues are hard to detect so perhaps thats why its under reported. Besides... I'm not Japanese and dont have their tolerance (whether genetic or environmental).
Gotta be careful with this stuff, I ate a bunch of seaweed and now I'm worried. Sigh.
I would avoid seaweed foods or snacks, since the iodine content can vary from 300mcg to 10000mcg between plants -- high enough to induce iodine thyroid dysfunction. Even 2000mcg can shut down a thyroid. Physicians even use Lugols (2000mcg iodine) in hospitals to shut down a thyroid storm.
Amiodarone -- a heart drug -- contains 2000mcg iodine and it is well established that 50% of the people who take this med will end up with thyroid damage from the high iodine.
See iodine-induced hypothyroidism and iodine-induced hyperthyroidism.
And contrary to public opinion, people in Japan suffer from eating seaweed too.
