More specifically, iodine deficiency causes goiters, neurocognitive impairments, and in severe deficiency, hypothyroidism resulting in cretinism.

Akron, Ohio was where a whole bunch of school girls were given iodized salt with their parents permission, with resounding results.

Interesting. A neighbor of ours grew up in this area, and later developed a goiter. Wonder if she suffered from hypothyroidism herself.

Are all salts (Reed salt from kenya, Pink salt in Pakistan,Common salt from the seas) same or do they have special properties. Do they have varying levels of iodine?


Happiercalif t1_irezbms wrote

Iodine is added to salt artificially. In nature it's in seafood and I'm not sure where else.


RunningNumbers t1_irh332d wrote

It distributes on land from evaporated ocean water. Plants and grazing animals then absorb it. You can get plenty of iodine from mills. Mountains are often iodine deficient since most water runs down hill rather than gets into the soil.


Happiercalif t1_irhdom4 wrote

I don't think that's true except possibly for very near the ocean. In the 1990s I read research about the Mongolians being very iodine deficient.

EDIT if you look up the Goiter Belt, it doesn't correlate to mountains. The Great Lakes region was especially bad, for instance.


RunningNumbers t1_irhf8ia wrote

Historically oceans have been seen as a primary source of iodine I precipitation but apparently there are other sources in the water cycle.

Also ocean precipitation goes far in land. Rain clouds that from into the Gulf of Mexico go well into Canada. They intercept cold fronts coming south and make T storms.


RunningNumbers t1_irhffdr wrote

You should look again at the map and then look at topography of the US before you make that assertion about correlation.


WintersTablet t1_irezg50 wrote

All salts have natural iodine, but not enough for the recommended daily allowance. The right amount is added in the factories.

For the most part, natural iodine is found in food, mainly seafoods, but it's also in plants that grow in places that weren't ablated by glaciers. These areas were known as the goiter belt.

And all the different salts, even the most expensive stuff, are functionally the same. One may taste better to you over the other due to taste bud differences formed by the foods you eat, or size of crystals, or other small things. But, in general, salt is salt.


DrEnter t1_irf11i3 wrote

Kosher salt and most “gourmet” salts are NOT iodized. You can get some decent iodized sea salts or course grind salts, but you have to look for them. They will always say iodized on the label.


WintersTablet t1_irf2g2k wrote

True that those don't have added iodine. I guess I didn't elaborate enough when I said it's added in the factories.

Although all salt has a trace amount of iodine naturally, it's not enough for RDA. So the labeled iodized salt has iodine added in the factory.

Also, I might add... Iodine is a poison, yes. The amount of table salt needed to consume would kill you long before any I'll effects of iodine were felt.

Not sure, and unfortunately the paper Business Insider is citing doesn't seems to go into detail about how they're mapping these AGCT scores onto IQ. That information is probably in one of the paper's own references.

>While surprising, this finding is consistent with the fact that in our data we find a very weak correlation between AGCT scores and education.

There's no significant amount of blood left in any properly prepared meat anyway. There's myoglobin left in the tissues which is often mistaken as blood. And salt doesn't really take it out anyway - I understand that's part of some rituals, but the salt merely draws out moisture. Some blood cells might come out with it, but it doesn't really draw blood out specifically.

Regardless, it seems that "classic" rules regarding blood and kosher allow for "blood" left in the vessels of meat? But I guess it's pretty complicated and there's more than one type of "kosher" designation.

There's way too big of a backlash against things like multivitamins too though, to the point that many people think they're worthless. They absolutely are not, and getting a perfectly balanced diet is a lot harder than many people realize. Basic vitamin supplements are a bad thing, plus there extremely cheap. A multivitamin is like $10 for a few months. Just gotta take it at dinner.

I mean perfect example I got a noticable benefit from taking some basic supplements, never spending more than $15 a month on it all (likely far less). I thought it was all just a scam like you, that I was probably just fine from a decent diet. Just fine isn't the same as good though. You shouldn't have to wait until you have a deficiency so bad that it causes medical issues. Vitamin D is by far the biggest one, most people just don't get enough sunlight to make their own. Maybe manual laborers in the tropics, but that's about it.

Tho I've never heard of anyone thinking you could just take more vitamins and get healthier. That's kinda ridiculous, they're dangerous in crazy high doses but so is everything.

Also gotta take your vitamins with food, always. They're just peed out otherwise.

Again projection, I followed your first link that is simply re-stating the starting assumptions by referencing "studies". In the references there are links but on following the links we get more of the same, we don't get to see if they are randomised, double blind placebo controlled trials or simply observational studies perhaps funded by people with an interest in the outcome.

In my previous post, the YouTube link has a university professor calmly and rationally looking at the evidence in favour of routine vitamin supplements. Each case he presents at first looks very promising in support until his reveal of what happens when the data is subject to critical examination or a proper randomised trial is done. Over and over what we see is conventional "it must be beneficial, look at the data" overturned by "Actually the high quality studies show the opposite".

The other glaring flaw in what you present is addressed in my two original questions you fail to reply to: What actual clinical issues are documented in quality studies by these alleged deficiencies? For example are we seeing 25% of the world's population suffering from Rickets?

I don't have a problem with correcting a vitamin deficiency that has been demonstrated with peer reviewed science. However a very lucrative industry worth 151 Billion dollars in 2021 Has an obvious vested interest in convincing people that they must have deficiencies in something which is addressed by using their products daily. If this was merely a waste of money that would be one thing but what persuaded me to stop taking them several years ago was the mountain of evidence that they could be actively harmful and when not in the form of food didn't necessarily work in the same way inside the body.

Also taking basic supplements costs less than $10 a month. Is this seriously a hill worth dying on when it is such a clear benefit to pubic health? I mean for fucks sakes we add all kinds of vitamins to our foods already because we were as a population not getting the full amounts needed.

I tried to buy a small salt shaker from the grocery store and all they have now is sea salt. So yeah, seems like it.

Hahaha…technically it would have had to be reduced when these yahoos were children.

But it explains this current crop of Americans.

I was shocked to find that a huge fast food franchise I worked for in high school had only non-iodized salt. Restaurants were supposed to be the main place to disseminate it to everyone, but I get the impression that either cost or taste is reducing how many places buy iodized salt.

Possibly, but apparent stupidity might be wilful ignorance or intellectual laziness. Intelligence alone doesn't guarantee any of the pleasant things that you associate it with. Even smart humans are just humans, and humans are stupid

They use to pipe in steam with iodine in it into classrooms to give the nutrient to the children.

I've never seen anything but iodized salt until I moved to rural North Carolina. Here, the grocery stores have more non-iodized salt than iodized. I assume it's because people here pickle and can more than other places I've lived but, given how under educated a lot people here are, I wonder if people choose non-iodized for regular use because they don't know to choose iodized.

There are folks who jump on every "it must be bad for you" bandwagon.

There is a iodine bandwagon. Wife's friend was on it for years. Had to use special pink Pakistan salt or something. She got sick, turned out to be due to lack of iodine. Her husband is kind of a nut also.

From the revisionist history podcast, places near salt water tended to not be iodine insufficient, which is where the dr got the idea to add it to salt.

Supposedly, people from iodine insufficient midwest ate potato peeling (as in baked potatoes) to provide iodine and prevent goiter. Iodized salt made that unnecessary.

For many it's because iodised salt has a more bitter and distasteful flavour than regular sea salt.

I've never used enough salt to notice. I'm probably one of the few people my doctor told me to eat more salt.

Serious question, is all the salt in my processed food (like ramen) iodized?

Don’t worry they’re ordering sea salt now to avoid the iodine

It's weird that when I came to the US, it was my first time seeing uniodized salt..

Holy $#!+ this is amazing! Especially after hearing all of those conspiracy theories about the govt putting iodine and fluoride in the water supply.

Salt bae should consume some of the salt he's been sprinkling to his overpriced food.

Now non-ionized sea salt is being sold a health food. I wonder how that's impacting IQ.

Okay, in a day late, but this part seems odd to me:

> The study also found "a large increase in thyroid-related deaths following the countrywide adoption of iodized salt, which affected mostly older individuals in localities with high prevalence of iodine deficiency".

That says that when they adopted iodized salt, thyroid-related deaths increased. Am I reading that right, or is it my iodine deficiency parsing..


kstinfo OP t1_irkadfg wrote

Makes no sense to me. Maybe it's a typo.


TwoFrontHitters t1_iroz9cm wrote

Government doesn't like this. They probably removed the salt and added fluoride to dumb everyone down.


xSpookNastyx t1_isohdy7 wrote

Unless you are using pure Himalayan salt, or supplementing with iodine, you don't get anywhere near enough iodine, from your daily life. "But they put it in salt?" Yes, they put it in bleached salt. By the time it hits your table, only about 10% is still active iodone, and only about 10% of that 10% is bioavailable... So what's that about .01% left for bioavailabilty.... Couple this, with the fact they removed it from food and water, and started using things like bromide in bread, and fluoride in water etc... They constipated your thyroid (arguably one of the most important functioning parts of the body) with these bad halogens. So now, people are fat, tired, and sick, and that's how they want you, docile and too dumb to realize you are being poisoned.
