Episode Transcription

00:00 Hey man, happy to be here, dude, happy or happy. Have you ever heard of iodine iodine like the stuff they put in your blood? What did they do that during your Marais? Is that diamond? Well, and I don't know about during M. R. I don't they put something in your blood to like make it a color on the thing, which feels like I don't know if they should do that. I don't know. No, it's it is. It's CT scans. Oh okay, but that I'm not wrong. Yeah, so you're yeah, you're close. Yeah, yeah. 00:29 Yeah, I don't know the difference between a CT scan and an MRI yeah. Neither you could. That's how you could tell the status of my health insurance. 00:40 And so especially when you're young and when you're in utero, iodine is very important because iodine is what creates this T3 and 00:52 I hate that joke. You hate that you laughed at it or you hate the joke? part of it? Skin milk is too strong. Too strong? 01:10 I mean you don't need one. I don't know the difference between a physical and a regular check up. You don't need one as far as I you how they check. If you've got strep throat versus hemorrhoids, I don't know. Speaking of like deferred healthcare, I have this thing. I haven't told you this yet, but I'm this thing that's been going on for about a year now where then this is going to sound crazy. I just don't like that. I said hemorrhoids and you're like speaking of deferred health. 01:39 this is a go on for a while. It's not ever. It's it's I don't have ever. Okay, no, there's this thing in this spot right here, right above my knee where about probably three to six times a day. It just goes completely numb and it's like a probably a six inch in dynameters section and like, how do you like feel of that's numb? Well, I just what do you mean? Like here's what happens. I'm trying to feel my thigh right now. Let me feel it. 02:08 No, like here, because what happens is I can't oh, because you I can feel it happening so like it gets kind of tight. Does it like tingle like what and then it starts to tingle and then it just like shuts off and then I touch it and I can't feel it and I I like it of that thing where it's like you're talking about the edge of your quad here right yeah and it's this thing where like I touch it and I'm like I think I can't feel that I'm not really sure, but it's like you know you're I can't feel that you know you like when you touch yourself you're like am I don't know this can I feeling this here am I feeling it here? I feeling it here you know 02:37 And so then one day it was happening and I was like, was like, Hey, grandma, close my eyes. Would you just touch me right here? And she did. And I was like, are you doing it? And she was like, yeah. And I was like, I can't tell. So yeah, totally numb. And then after a while it comes back and it comes back with the tingles again. And then it goes back into the tightness and then it just kind of relaxes. So I don't know what that is been happening for a while. I should probably see a doctor probably too high as sodium. I so. I think so. Why? Cause I think that would affect the circulation to that or your 03:06 just really dehydrated, probably both, but I probably a combination of too much sodium and not enough water. I mean that's in that's just my estimation a ton of water. Okay, I'm just making sure I can feel my leg. You got to be kind of paranoid about it now. I feel your thigh. I feeling this right now or is it just the tips of my finger that are I don't know if I five hey, I'm going to close my eyes. Will you touch me? I don't feel that 03:31 No yeah, it's stressful, so I should see a doctor, but you haven't. I have it okay, and I don't have an excuse. I have health insurance. I have health insurance. I also have health insurance. To be clear, I we were joking. I haven't sure I have health insurance. Don't you think you'd feel a lot better if you had life insurance and so so like I started, I feel like I need to go get this check out okay, and the more I think about it, the more it starts to stress me out. 04:01 So if you go to the hospital, they're going to put iodine in your blood and then they're going to put your leg into a machine. I don't know how cascades work. I don't know either and that's not what this episode's about. Great question. Let's talk about iodine. I can tell you this is iodine. Yes, it is well. It looks like pencil shavings. This looks like yeah. This looks like if you took the edge of the the lead pencil and just 04:28 I had itself is a chemical element. Yes, this is like a mineral version of the iodine element. I love when you choose ambitious topic like stuff that you're clearly not going to cover. Well, you don't talk about like where it's like this, this is iodine and it's on the the table of elements. Is that what we call it? The it's a chemistry thing and it's a this is in a physical form. 04:58 I here's the thing. Here's the thing. That's the this whole start. Yeah, keep trying to talk while you're starting the timer, buddy. That was awesome. So okay, here it is. It's a liquid of ish form. It's liquidizing. Okay, uh the word for that is sublimation. I know that word, so it's this like purplish element and this is an interesting thing because it is a heavy. It's called a heavy metal and that's not like it's because it's so dense. 05:26 and it actually does a couple. It has a few interesting properties. One of the things that it does is when you put it into a starch, it turns like dark blue or black and this is a picture of iodine drops being put on a potato like a a fourth grade science project by the way yeah and so I had itself as purple, but then you put it in the starch and it turns blacker or whatever and this is actually used in these iodine pens, which is how we know if 05:54 US dollar is counterfeit right right right right because if US dollars are made out of potatoes, that's exactly right. No, they're made out of they're made out of cloth, not paper and paper is a starch and so paper would turn the black or blue when you used it, but it doesn't change a cloth. Yeah, they're like a clothy material and it's not like like actual cloth like you think of when you think of like. Do you have any money to see or do you need? No, I yeah, if you can spot me somebody to look at some money. We're like there's a couple hundred 06:24 there you go. Yeah, yeah. This is like a cloth. It's like a cloth. Yeah, I don't know if you guys can hear that, but that's cold hard. That's the sound of someone who just filmed his comedy special baby. Do you carry cash? Sometimes yeah, I try. I genuinely don't use well. I'm in a lot of scenarios where I have to tip people yeah, you know, because that's where you get rich and I don't carry like I don't carry cash the way that like 06:50 I carry cash when I travel. guess I was with a friend. have a friend who has money yeah, you know it was one those things where we were getting ready to the bill was like a hundred and fifty bucks and so we're pulling out our card and he goes I got you and he just pulls out his wallet and he just opens his wallet several bills in there and just pulls out a hundred and pulls out a fifty and gives it and so was like I didn't want to be like how much cash do you have on you right now? Yeah, yeah, but I also 07:16 I kind of wanted to know how much cash do you have on it? You know he was one of the thousand that you're just carrying in cash and he's like yeah, here you go. That is that is crazy like because I was like I got to rob you. If I if I have more than fifty dollars on me, I'm stressed about it. Yeah, I'm like I got to get like I'm gonna. feel like I'm gonna lose it. Yeah, I this has to go somewhere else. I am the opposite of the Dave Ramsey rule where if I have cash, it's like not real money to me. 07:44 because like real my way in my account is like assigned to bills and stuff and this is just cash and my wife's not going to know if I lost this or if I spent it that's oh oh so it's like it's like hidden hidden spending. Oh and that's probably healthy. I'm you do that with your wife. No 08:03 you go hide little tiny purchases from each other and maybe you're just like oh she doesn't have to know about this yeah. Yeah, I just need to take out like twenty thousand dollars. just take out twenty thousand dollars cash. What are you Tim? What are you? What are you sporting on this because like twenty thousand now is not an amount that you can get like a crazy good thing for you know saying like you're just hiding a two thousand twelve Honda Civic from your wife. It's pretty sick. That's right. too a grand 08:30 twenty grand could still get you like like a twenty nineteen on to yeah point twenty no, because mine to twenty seventeen and it's worth eight. I think yeah, so it does depend on the mileage. That's true. That's true. Yeah, yeah anyway, or like a jet ski. 08:47 you know, I have a secret jet ski. I have a see. I have a secret. My wife doesn't know about my jet ski. We don't live anywhere near a lake and I have no way of owing the jet ski to the light. Keep it hidden on behind our house and dollars was those jet ski electronic games from Chuck E cheese where you can just like yeah, but I can't keep it at my house, so it's hidden behind. I have rented another apartment. 09:15 it's a studio department that done at all. it is in the studio apartment downtown is more expensive than the rent that I pay at my apartment. I it's an elaborate lie that I've been living and I also had a hundred dollars at the apartment. have another wife and a kid and 09:32 and and they and I like idea that you have a whole secret family, but you lead with. have a secret. That's key. The jet skis the secret yeah she know she knows about everything else yeah. Yeah, it was about all that. She what all is up. didn't know about the jet skis. That's crazy. Okay, so I yeah, that's what is used for those pins. I did these for those PED and the reason I died is significant is because it is poise. I feel offended 10:02 by the way, when I pay with cash and someone pulls that pen out. Oh yeah, because it's like oh you don't trust me. I literally I do feel that way. I go okay, well, especially if I'm a regular at that place, it like I'm like you think that I actually maybe I'm flattered. Maybe I'm flack. Maybe you yo you think I'm a criminal. You think you think I could do 10:30 Yeah, it happens to me almost every time gosh, but there is it happens to be is because whenever I pay with cash, I say it's real yeah. I mean that don't go yeah yeah. Okay, this is real and they go. It was don't say that next time. Why else would I say it's real? So the I had one. How are you okay? So I died is interesting because it's a poison. It will kill us, but that's what I'm saying simultaneously. It is the heaviest element 10:59 that is essential for most living organisms, and so we and most living or did you search this up just because like we put iodine on the salt like I dies salt and you were like, but that could kill us and then and now you're trying to do an episode about this. Is that how this started? The shame that you had and then you pull up a picture that you had ready and here's exactly how this went. You went wait, but that could kill us. 11:27 and it's like Tim, any chemical could kill you at too high of an amount. I could end this episode right now. This is really embarrassing for you that I hard for the audio listener. He just shamefully he had this cute up as a picture of the Morton salt. You know what the girl, the umbrella on it, it's crazy because it's a poison, but like we put it on everything. So you're the thing 11:56 so here's what's interesting. All right, sorry, I let you talk. Okay, no, no, go back to the beginning of your script before I said to you that here's what's interesting. It's it's a thing. What are we doing? What are we doing? That's so good, so yeah, it's poisonous, but it's also essential for life. Most life what's interesting is yes, most chemicals. If you do too much, it'll kill you yeah, and that's true of iodine 12:25 But iodine is significant because the amount we need is very, very small. The recommended daily intake is 150 micrograms. So it's smaller than a tablespoon of salt, or a teaspoon of salt. Very, very minute amount of this that we should be taking in. Any more than that, and then it does become something where you're putting yourself at risk with the amount of iodine that you're intaking. But this has a very serious health effect. 12:54 the the part of our body that regulates iodine is the thyroid yeah. Here's the thyroid gland. There's your Adam's Apple. I got a because I thought that it was funny that I had that it's not just I need. I just wanted to be really clear. Sorry, I didn't that sounded mean, but like you pull up a different graph. You're like here's the Adam's Apple and it's like that wasn't. I just thought it was really dumb like that. 13:18 Adam's apple is not like a medical term. I'm like who made this graphic anyways, someone who is trying to get its Web M D dude, they Web M D is trying to get normal people to understand things, whatever fine. This is this is the thyroid. What here? Here's the animal. Here's a way. Where is the items apple on this just so I a normal person so the me a dumb can understand. If you look at the thyroid, see the thyroid sure right above this task. little thing that looks like an apple above it yeah. 13:48 So the way this works is your body needs these three, I guess, chemicals, T three, T four and calcitonin. Sure. And those things, they, they provide a lot of functions for the body, but probably the biggest thing is growth. And so especially when you're young and when you're in utero, iodine is very important because iodine is what creates this T three and four. I've never been to utero. 14:15 I I've always wanted to visit hate that joke. You hate that you laughed at it or you hate the Joe I both part of it, which part of that joke so I think I'm going there on a cruise next year. Here's beautiful this time. So T three and four the three and the four is like the amount of iodine molecules that are in that chemical or in that or about V. Tro what here been in V. Tro 14:44 I think that this joke's still going on. And so a little bit of iodine has to be a part of that compound that goes throughout our body that helps our body growth and a lot of other things. Sure. Your metabolism uses these compounds as well. But the this is regulated by the pituitary gland. So the pituitary gland in your brain basically gets a signal and that signal is we need some more T3, T4 for all these essential functions within the body. OK, a little low. 15:13 and it sends this chemical TSH, which is a compound that triggers the production of T three and T four in your thyroid. So that way more is produced. The problem with this sister, what's insane about everything's happening on our podcast is that it's just stuff like I'm trying to I'm on the listener side right now. Okay, because so much of our show 15:39 is you being like this guy founded the Backstreet Boys and look he's got a fake plane, you know or or this woman won the lottery in a ruin her life and then sometimes you just venture so far out of your own depth. They are like yeah, so the Perttuartary clan and we're all sitting here being like I didn't sign up for med school to him. I'm here to do a funny podcast. These people are on their way to work right now. They're 16:04 barely awake. They're here for some ha ha's and you're over here being like yes, the between take land the TSH combo. We actually need for growth and it's really important for our foundational growing years and it's higher in children, but the T three T four in the council tone and and then you know the hypothalamus, you know the whole thing is and that's your Adam's apple and I sorry I thought that was super funny. I it's so crazy how you're so willing to venture this far. 16:33 away from the boat. You know first of all funny point. Second of all, I feel like I need to correct you. Tsh is what the to the go. You're right. T for yeah. So sorry, sorry, sorry, sorry. See that's how little I was paying attention to your rambling earlier, but what's significant about my God. I feel like I'm in eighth grade science right now. Can I tell you what I did to my eighth grade science teacher? I tripped her. uh That's true. 17:03 she was walking and I had my foot out and she fell over it and then I very stealthily moved my backpack to where my foot was. So she thought she tripped over my backpack and and I know that's me and listen. I'm not saying that I'm proud of that. It was funny, but I'm not like it was funny, but I'm proud. It was now. I understand that I'm not. There's so many things you understand as an adult where you're just like aw crap, dude, that sucked. She was just at work. 17:29 Yeah, that's why she hated us. Yeah, she hated us because she was barely making enough money to survive, and we were awful. Yeah, we were the worst. Yeah, I think about that all the time. I was pretty. She didn't fall completely. She caught her, but she tripped a little bit and she was really embarrassed, broke her wrist, no, she did not go down to the ground. She literally did that thing where she was like whoa. She looked back and I was like I'm so sorry my backpack, but it was me. I did it digitally. You want to apologize for that? No, she was awful. She was 18:00 Yeah, but was she awful because you were awful? No, actually she she was awful in the way that was like if you're an athlete, you're allowed to say and do whatever you want in her class, and if you're not an athlete, you are not allowed to speak in her class. She also was wearing this shirt that said please be nice. I'm going through a divorce. Oh no, oh no man. I'll tell that that story then, and this is a friend. They I you know that sucks. 18:26 I hate that whenever you talk to a friend you haven't seen in a while and you're like hey, I you know, so was I was messaging John the other night and just seeing if he was going to come to the show and then and then his wife who I'm talking to ah is like oh yeah and I was again he said he was he was traveling this weekend and she went yeah he might have been traveling this weekend. I don't know and when she says that 18:49 you kind of put together what's happening and I think that if you're going through a divorce, you should have to wear a shirt that says please don't bring up my spouse. We haven't seen each other in a couple months. It's a really sensitive topic for me and it'll be very uncomfortable for you because then I got a message later. It was like hey, just so you know, here's what's happening. I'm like I wouldn't have said anything if I knew I truly feel so terrible about that. 19:15 Facebook should add a new so like when your friends are going through that it's like hey, if she's gonna be there, do you want me to like tell you? Do you want me to not invite you? Yeah, I also let the dynamic. don't want you to see that we all hung out as friends. Yeah, even if she's not in a picture, I don't want you to see that like we all went out to a restaurant and you weren't invited and I don't want you to feel like yeah, you know yeah there that is it's a tough time off man. Yeah, so 19:44 I'll never do that to you. Let's make a pact right now that you and I are never going to get divorced yeah, so that so that we never put each in that position. Yeah, I'm just staying together so don't make Jared. love my wife a lot. That's that I'm going to make that very clear same. I feel like I feel like this is the time where I it was a joke. It was a joke. Oh my gosh, but 20:12 I also it adds there's pressure yeah, you know, yeah gotta keep it together. I got to give it together so I don't embarrass him. 20:26 Hey, thanks for watching our show. you like it, a great way to help out is by being a Patreon supporter. Doing that helps make this show possible, but it also gets a lot of perks for you. You can get every episode a week early ad free. You get access to a Discord where you can meet a lot of other people who love the show and actually hang out with Jaren and I every month on a hangout. And we're also in that Discord chat all the time, hanging, talking with people, talking about episodes and just random stuff in life. It's super fun. 20:49 We do, there's a way to get birthday messages, a free gift, merch discounts in there. So there's a lot of really great reasons to be a Patreon supporter. You get a lot of benefits out of it. And it also makes the show keep happening. So if that sounds great to you, you can go to support.tillin.com or tillin.com slash support, uh or just tillin.com and search around until you find the links and become a Patreon supporter. really appreciate you doing that. But if not, right back to the episode, right? 21:17 I don't know why she comes out of there. I didn't to talk about that so and she's like turn. think I wanted to work like no, no, no, no, no, hey, hey, we will. I'll do anything. We'll work through this. We can't do this to Tim. She's like what are you talking? I probably I'm heartbroken. I'm like oh, I'm processing the feeling like oh my gosh, you want to leave me. This is terrible, awful, but also like 21:39 this is so bad for him. So bad for my divorce is really bad for him. He's going to be so uncomfortable. That's never going to happen. That's never no for real. Do my wife often says to me she looks at me in the eyes and she goes you know we're never getting divorced. She'll just do that so that's so great. Yeah, I wasn't planning on thanks. She goes you're with me for you can't get out of the show. Just remind me that sometimes I go yeah. I mean like but she'll say it in a way that's like threatening 22:08 yeah, I'm like I wasn't. I was never hoping was never thinking that yeah, we're locked in dude. I love you. I want to be with you. Yeah, like good. 22:18 she backs out of rooms. Lately, that's a thing she's been doing. She doesn't move her legs either. She just kind of freaking move your legs when you want. No okay, so what's significant about this is the pituitary gland doesn't have a mechanism to say oh we are making too much. It only has a mechanism to see we don't write right right and so if there's something wrong with that interpretation where it's like oh we don't have enough. 22:43 yeah, we'll just it'll just keep going, keep going and then and then you and then a lot of people gain weight because their thyroid is out of whack yeah, and so there's all sorts of different issues that could come out of that out of that. I got my thyroid tested when I was large because I didn't want it to be my fault. What did they say? They were like it's your that's true. Like I was big. I remember I got the call. It was and I think you were there for that show. I was in the alleyway of the show where we played at lemon drop 23:12 and it was like the garage was open. The lemon drop was such a weird venue. I loved it. I loved it to modern craftsman is what it became, ah but it was like the back area with the Rogers open and what was what was their band called ah the sisters, the Malone sisters and Jared Stantler. Oh Willow something. Was it just the Willos? It might have been that sounds right. I thought it was something with an L in the beginning. 23:39 maybe I'm wrong, La Willows, but anyway, I got the call in the alleyway and my doctor was like yeah. Everything's normal and I literally hung up and I was like oh, I'm just big. Oh, it's just me. I just because I it's probably because I ordered a dozen Fasoli breadsticks to the drive through last night for two ninety nine that might be contributed to my weight gain, but honestly such a good. mean in this economy, so so yeah, so it doesn't have a way of being like as is too much yeah and and what ends up happening is it's a 24:08 It's a growth thing. Yeah. And so what was a long time issue across the world was this condition called Goytters. And what Goytters was was when your thyroid just continued to grow. The thyroid would grow. That's the thyroid itself just swelling. And for most of human history, people did not understand that this was the thyroid. Like all of a sudden you would just have this growth that would appear and it would 24:32 range in size and so yeah, it could be a for those listening. It's a giant growth in your neck. I could just like it looks like a gigantic double chin that just forms. This is going to be a kind of disrespectful way to describe this, but picture a and then make that human ribbit like a toad where the like next is a very disrespectful, but accurate way of describing this. I like that you were like this is going to be sound mean 25:01 uh And here's the thing, people did not understand that this was because of iodine issues. What they found pretty early on was that sea sponges were a pretty good treatment. so people would give them, or doctors would give them sea sponges to treat this. And the reason that worked is because there's a pretty decent amount of iodine in seawater. uh so... That's it's so salty. Yeah. so, no. That's not why. Yeah. 25:29 What else can I get you to agree? These were a treatment and what was interesting is the way we have always historically ingested iodine sure to feed our system is through the foods that we eat like through plants we eat because it's in the soil and it gets in the soil through rain water. Okay, and so the closer you live to the ocean, 25:56 the more iodine you're getting naturally through your diet. the plants that grow in that area have more access to iodine. The further you live inland, the less you have access to. And even furthermore, the further you live north, in an area that used to be a glacier, uh even less, because the glacier tore away that soil that would actually have iodine. And so the places where we saw the largest amount of iodine deficiencies were up north, more inland, typically. 26:25 uh Europe, where you see this a lot, is like Northern Europe and like the Netherlands, Norway, uh all over like that side of the world. uh The other issue that you can get from uh iodine deficiency is eh a condition called cretinism. And cretinism is a condition that's almost completely eradicated, at least in like the Western world today. And what it is, is it's a... 26:54 stunted physical and mental growth that results from like fetal deficiency, and so if okay mother uh is not getting enough, I that what we call it like we're like oh, that's a cretin. Is that the same? I'm pretty sure that's just like that feels from Crete disrespectfully and mean like the only if it's like a cret the only way I've ever heard that uses for people from Crete. I don't know if you've heard that as like a disrespectful way to say that yeah. 27:24 have you? Am I wrong cretins? I don't actually know okay, but it's it's like a significant, so it people who have cretinism they have a my thing is something else. I'm thinking. I don't know trying to think of a scenario where he's now you got me guessing, but here's the thing about when you when you second guess me. I'm usually right. What are you talking about when you're like? I've only heard people from creed called that and I'm like no 27:51 People from Phoenix are called Phoenicians. Probably right. 27:58 um No, cretinism leads to a series of ah disabilities, mental and physical disabilities, because that fetus wasn't able to grow properly. And so it was, and it still is considered the leading cause of preventable intellectual disability is an iodine deficiency during pregnancy. Okay. Because that child isn't getting enough iodine in their diet. And so when this was discovered, 28:27 that iodine was the thing that we need to prevent goators and all sorts of other uh conditions. There was this move in the early and the nineteen twenties to iodized salt yes and uh so this was kind of a slow rolling thing, um but eventually because even in the nineteen twenties they were like listen. You know what people love sodium. We got to figure out a way to sneak this into their diet uh kind of 28:56 And so doctors basically proposed if we put a little bit of iodine into the salt and we just like in liquid form, just spray it on some salt, uh then people will get enough iodine in their diet. Yeah. And this popped up because there was an actual problem in World War I. uh The army couldn't enlist anybody. Well, I should say couldn't enlist anybody had uh more difficulty enlisting people from Michigan than they had anywhere else in the States because the people in Michigan 29:25 the men in Michigan couldn't button their top button of their uniform because they all had coiters because they were inland and they used to be all had coiters. I not all but a significant portion of them had coiters and so there was they were like why are there so many people from Michigan that we can't that are medically unfit to serve because they can't button their top button and so they start. That's how was decided if you're medically unfit. Well, it was a it was there's 29:52 other. It's not just you have this. There's other conditions you have when you have goators, but that's that's what made them realize they're like you can't button that button. What's wrong with you? And they're like, well, don't you see this thing on my neck? I have glitters. Gotcha. Okay. And so then doctor started to research this and that's what made them say, well, if we can add it to the salt, then we can distribute it more into the population. So in the twenties, this became a really big thing. More and actually resisted it pretty heavily because what most national salt companies did is they said, well, just put it in our Michigan. 30:22 salt, our salt that goes to Michigan. And Morton was such a big company, they're like, it'd be too hard for us to manufacture specifically for Michigan, so we're not going to do it. But then when they saw the sales of iodized salt in Michigan, when the public started to understand the point of it, they're like, oh yeah, we're going to do that. And so we're going to do it nationwide. And so then salt became, iodized salt specifically, became seen as like this healthy thing like you need to have in your diet. And it became a very big deal. And what was really interesting is this is something we haven't discovered until 2013. But in 2013, we went back and we studied the data. 30:52 from the window between World War One and World War Two, where I saw it became the norm and we looked at the ah military. What is the exam called? Basically the the mental exam that they give the presidential fitness exam. No, it's the mental exam and so it's the it's the examination that they give the military when they enlist to just kind of see where they where they sit mentally ah and the I was trying to pull out the ink splotch test, but I can't think of it right now. 31:22 the inks inkblot test. Yeah, what's it called the right? Yeah, I don't. Yeah, you're on the right, right? I can hear your your close. You're so close. Reckoner close ret. What is it? Roar shock. Roar shock. Ah, yeah, I was so there. Yeah, I was a good joke. Let's pretend I got it. Okay, yeah, here we go. Yeah. So they had like the mental military. Oh yeah, yeah, like the 31:52 Oh shoot, what's the the ink plot test? What's it called? I'm right here with it. Oh no rock shock rock chock rock the rock chock test. that doesn't sound right rock. What is it? Google it real quick or shock dayhawk roar shock or shock a hawk. That's right roar shock. Golly man, I tried again. had the military metal 32:20 assessment does. yeah. 32:31 that I've done that in the previous episode and you fully fell for the first time. That was great, so now this military mental assessment test. What they saw is the average um the average scores ah compared from people who enlisted in World War One versus people who enlisted in World War Two was uh an order of magnitude higher in World War Two and what that attributes to 32:59 is about fifteen IQ points on average, and so there's a significant leap and I can IQ points. Can you do an episode of the gifted program low? Do you like at school? Yeah, there's every school have like the same gifted program. Is it the same thing? There was a national. Do you guys have a gift of program at your school? Yeah, were you in it? Yeah, yeah, we knew as soon as he sat up where he went. Yep gifted man over here. No, I know we had the vibes. Yeah, yeah. Do you think I was in it? 33:29 probably okay. Do Tim was in it? I we have a gift. don't remember what the what the qualification was other than being hot and they were like they took all the hot for like all right. You guys are gifted for sure. I don't know what the there. No, there's like there's like standards at least like you know and maybe it'd be interesting to see what Missouri standards were versus yeah. I genuinely don't know anything about it we didn't have that in private school like we had like you could take like 33:59 like once you got to high school like they had like college credit courses. Yeah, I know this wasn't that, but it was this was it was different. Well, we'll do an episode about it. Okay, I'll also learn about it. I guess I'll have to get the gift. Yeah, well, why don't you use this medical interest that you suddenly have to search out? Yeah. Hey, hey, if you like this episode next week, we're talking about shingles for some reason and we love for you to you know, but this is interesting because this using I 34:29 iodine and salt, they estimate over the course of the 20th century. What are you doing? I'm looking up this week sponsor. Hold on. I know that we have like a thing over the course of the 20th century. They estimate that iodine, iodizing salt attributed to across the entire population, a 180 million point increase in IQ worldwide because of all these people who were all of a sudden um ingesting more iodine in utero, which meant their brains were able to grow more. 34:59 wow, they were a fetus. That's crazy yeah, and so uh what is interesting is we found uh evidence that before this that most locations in the US and you're going to hate this most locations in the US that did not have access to iodine naturally in the soil. A lot of people still had plenty of iodine in their diet and the way that they had that we discovered was because of dairy and there was two reasons for this. um What 35:28 Again, I cannot overemphasize enough. You're going to hate this. okay, the the iodine link that we had was within cow feed. There was iodine trace amounts of iodine that was found. So cows had iodine in their system. But what was more prevalent was most dairy farmers used a very similar disinfectant called Eido force to clean their milking equipment. 35:58 and that would leave trace amounts of iodine left on all of that equipment and when they would milk cows, that cleaning solution would get into the milk and people would through milk and cheese and other dairy and just all the iodine that they needed from that, which is I love that. I actually think that's really great that the core rock star way out of that and in why would I hate that? I don't know. I just think it's gross. I I would hate you. You think that you think that I, a person who never crashes out, 36:28 would hate that cleaning solution got into our food supply system and then that was enough of the cleaning solution guy to our food supply that was able to you know. I why would I a person who never crashes out? Why would I hate it? I you know I'm I'm surprised. I don't know. I realize that we crashed out too much and then I remember the prisoners listening to this and it's like they don't give a crap about it. That's not the state of the dairy industry is not on their list of concerns. Yeah, you know yeah 36:57 so I've been trying to do this episode for them. Well, okay, great. Do you like that? Do you like that? Is that was that? Was that you're making me mad? You're sorry. I didn't think I would be received the way you received that. Okay, so keep going. So okay in two thousand five there was a big push to remove these kind of chemicals from our cleaning material, got you and what's very interesting is there is a noticeable 37:26 uh decline or noticeable increase drop, you notice will increase in iodine deficiencies across the states when we did that because a lot of people were still getting it primarily from their dairy. So at any point in life, this isn't just a like an iodine deficiency. Like if I stopped consuming iodine completely today, I would develop that. Yeah, so there's there's this isn't just a there's two impacts like when in utero, if your mother is iodine deficient, 37:56 then it reminds me of my I need to update my passport for you to row. I'm going to a music festival there, so if your mother is I deficient, you're going to have issues developing and so what about dignity? What indignant? He ate this bit so much and I hate that I just fell for it again. I that I felt okay, so you're going to have 38:21 you're going to have conditions, indivisible with liberty and justice for yeah. I've been indivisible before I was there with liberty and justice. My bow, you know them, you know liberty and justice for all for all. That's their last name for all for all their twins liberty and justice for all that's indivisible with liberty and justice for all this. 38:50 you hate that you're laughing at this. I also am not proud. Here's the thing about most of my content that I post online and stuff is like people are like oh, just stand up comedians used to like write brilliant stories and and call backs and these intricate things and now they just post these clips online and it's like yeah dude it. I'm not proud of the stuff works. That's what works though. Yeah, yeah, it's like yeah dude. I also wish that my intricate well thought out and well crafted stories were the things that went viral, but they're not 39:18 Go to a show, you'll see the roadcrafted stuff. That's what I'm saying. For real. Yeah. Online, you're going to see, I don't want to call it hacky, but it's just like, yeah, it's the first level joke. It's stuff that's like, oh, this would hit hard on Twitter. This would hit hard on... Because it doesn't take any context. just... I've got eight seconds and you're going to share this with your friend. Yeah. And it's like, yeah, I mean, I hate that. I hate that about the art as well. But you know, that's not why I'm doing Indivisible jokes. This is just funny to me. But it's like, yeah. Anyway. 39:48 So anything in utero, those deficiencies cannot be reversed. Like that is a developmental thing. Oh, gotcha. But once we can't just pump you full high down. Yeah. And I should say too, like as an adolescent, like if you have deficiencies, there's certain things in your adolescent development you're not going to able to reverse. Got it. But as an adult, a lot of these things can be reversed because they are conditions brought on by essentially an issue within your diet. OK. And so if you can supplement that. 40:16 and reverse some of those effects, technically. Some of those effects, like if they run on too long, they can create knock-on effects that you can't reverse. But some of them you can. uh Does that make sense? Yeah. Okay. So uh what is really interesting is over the last 20 years, not just because of the dairy, we have seen like a massive spike in iodine deficiency. Okay. 40:45 chase back to uh changes in diet. And so over the last 20 years, there has been a pretty large amount of chefs and consumers who have shifted their usage from I dies like table salt to kosher salts and sea salts. And honestly, like I was thinking about this when I was reading these, like, oh yeah, a little, yeah, I can't think of the last recipe I have found online. 41:14 that didn't call for kosher salt or sea salt. Like I don't remember last time it just said salt or iodized salt. ah It's just always been kosher and see so and honestly like we have both at home and I've only used kosher for a long time. There's also the last twenty years been a really big rise in plant based milks and so that not only the okay, not only you know what for a second I my brain was like milk based salt. I don't know why when you're like plant based milk 41:42 you said milk and my brain was like milk salt, but I trademark that yeah milk salt milk salt. That's gross. You like crystallize milk and his salt and then poured it on your steak that faces a fits getting all my new trees. 42:07 Hey, thanks for listening to this episode of things I learned last night. If you like the show, you want to support us, we've got merchandise that you can get and it's good stylish stuff that I made. put a lot of work into this stuff, so it's great to find other tilling fans in the wild and be like, wait a minute. I know that shirt. And so yeah, we would love for you to do that. You can pop over to shop.tillin.com or the QR code or there's a link in the description. There's plenty of ways to find it. We promise we made it super easy. So thanks for supporting the show and thanks for listening. 42:38 here's what I hate. I cannot stand whenever someone's like here's my new high protein dessert and I'm like is it cottage cheese and they're like all you got to do is you need to combine chocolate chips. I'm like it's cottage cheese and they're like and then you got to get your blender. I'm like here comes the cottage cheese and then put one top of cottage cheese. Gosh, I'm not making cottage cheesecake. 43:04 cottage cheese. I'm not doing it. It's so gross. 43:10 I need to make that. I need to do some videos where I just react to those rise. Go is it cottage cheese is it cottage cheese your car? That's part is cheese and that is a kind of hacky that will work on social media. Don't ever call it. Don't point me and go kind of hacky. Hey, kind of hacky, kind of acky. Wow, I can say that that's our word. Sorry. Oh sorry as a is that a thing? Okay, sorry as a 43:40 Comedian diagnosed diagnosed. 43:46 my doctor says I have comedy. uh My doctor says I have the gift of gap. I don't know it's a plant based milks. Obviously, like we shifted from having iodine, but okay, but cows still get iodine through their diet, and so you still do get some through. the I don't get the I mean I get it for lactose intolerant people, but I don't drink it as like 44:12 if I'm just going to try to whole milk. I honestly haven't drank just a glass of milk in forever. You shouldn't that's that's murderers do that a lot of our podcast list. If I cook with milk, I'm using skim milk, ah but for coffee, I use milk alternatives because I do think milk like even skim milk is too strong. That's all I can taste. I don't taste the coffee and so I usually use oat milk too strong. 44:37 oh yeah. I hate whenever I over skin milk is too strong for me. That's the dumbest thing you ever said. I just don't like the I can't taste the coffee. This yeah dude, whole milk is too spicy for me and so so we've pulled back on plant based milks, process foods also I and I salt 45:03 um so do you think that we're trying to solve all these other problems and we're creating one that's to sneak up on us? Well, kind of because the because process foods though is a little different because process foods are doing it because like it affects color and they think it affects flavor, but a lot of blind taste tests have said no yeah and then there's also been a lot of salt reduction initiatives because like there's public health. I hear like the getting too much so and not enough rider colored foods like when I work at subway. 45:29 Yeah, it's like yeah, do those tomatoes are pretty bright red. The banana peppers are very bright yellow. The jalapenos are bright green, yeah, but it'll be honest. They look more appetizing to eat. Yeah, they do. Yeah, because when you take that stuff out doesn't really affect the it doesn't affect it at all. They just tell you it does. They're like oh, and the guy who says it sounds like this and so it's like don't. Why are we trusted and so yeah, but it looks gross. Yeah, 45:58 anyway, and so what's really interesting is over last few decades. We actually have the data from pregnancies because we collect this data. All these people, by the way, who do this stuff will fully eat like sour gummy worms or like oh yeah, oh, I don't want any any trace of that stuff in these in the vegetables and you're just like 46:19 people. They're just like easy. Yeah, but when you go out, you have you have cocktails that have more poison in them than this does. It just it's inconsistent. It's stupid. It's just it's all anyway, whatever, whatever we have the data because we collect iodine. I used to eat family size bags of Doritos. Do think I care about a little bit of coloring in my banana peppers? No, I used to sit down in one sitting and have a family size bag of Doritos which 46:49 is awesome and honestly I was I was happier that maybe that's what the problem that the problem is. I was happier. Oh shoot dude, I should be eating a dire fan. I should fat again dude. I was so much happier back then. I didn't think about anything. I never worried about working out. I didn't worry about what I was eating. I didn't care about how like the world was doing. I didn't follow the news. All it was was just food. I was fat and happy 47:18 Oh no, right. That could be a fast forward to a year from now clip this. So I next year when I'm just sitting over here like 47:30 honestly, and then I'm over here like I didn't work. I still sucks. Everything's still bad. I hate this honestly would be great for another special to like just come into that bit and call it fat happy fat and happy where I just gained a hundred pounds and then I was like yeah. No dude, it's so hard like losing weight is so difficult yeah that it's like I'm so terrified if I if I ran it back. Have you seen you? 47:56 you watched always sunny right yeah yeah yeah where he does it he gets fat man yeah, but like they and this is the thing do they can pay for it and that's you know, because he talked about that in interview where he's like people like oh, how did you get shredded? He's like well, you got to be able to pay someone to make the meals for you and pay a trainer to come to us like it's and here you know what okay not to crash out on comedy stuff again, but I I found out a comedian that I follow who is funny. I'm not trying to take away from their art right yeah. They are funny, but I found out their dad's the CEO of the company that owns Grand Theft Auto 48:25 and I was just like, Oh, so it's like if this doesn't work out for me, yeah, then I have to go get a normal job and like live with the pain of like, yeah, my dream didn't work out and now I actually have a bunch of debt because of it. Yeah, yeah. And if it doesn't work out for that guy, he's fine. Yeah, nothing happens and it's like art and honestly, even if it works out for that guy, also nothing really happens. 48:53 what I'm saying is is that and people, oh, you're just jealous because they have financial security. Yep, yeah, 100 % like I'm I'm not. I'm not. I'm I'm trying not to be bitter about it. I'm not like saying it's their fault. I don't fault them for that. I'm not saying we should strip them of their financial security. I'm saying yeah, if of course, if I had a financial security, I think my jokes would be a lot better because I could think about stuff that wasn't, my gosh, you know, making sure that all the stuff's time on survival. Yeah, yeah, yeah. 49:22 Yeah, which is a real, which is a genuine thing and a genuine thing about human history is like when the the society at large had the most amount of population. He was financially and like physically secure in terms of like the majority of their base needs were taken care of. Yeah, the society advanced way further. Yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah, 49:48 Oh, what was it talking about? I saw this recently talking about the the Rorschach test. Oh, it was the podcast you sent me. He talked about the arts and he said that's the biggest signal that a society is failing is when the arts begin to fail right because that is when there was a really good interview. Chris Gethard's been out here doing some interviews circuits kind of thing about the DIY stuff because I just filmed my comedy special and I paid more for my comedy special than I did for my wedding. Yeah, and that's a thing that like and that's what I mean is that if I had the financial security, I could take bigger risks. 50:17 I had to do this on kind of like a pretty tight budget and it's good. It's going to be great. I'm excited for it. But if it doesn't make that money back, I'm just out that money. that's like, and that's something that you feel like financially. That's something that's like, I will feel the pain of that. And so that did put a lot more. And this is what I mean is that during the filming of it, 50:44 the pressure of filming this special to a level of performing and then editing and doing this special in a way that will make money made the product worse. think yeah yeah because you're like trying to it's that uh the you're trying too hard to look like you're not trying that hard. It's a whole thing of like you play. It's like whenever if you're an athlete and the college scout shows up and then you're playing good, you're playing well like you're not playing. You're not flopping yeah 51:12 But you know that you have played better. Yeah, yeah. And you know, like, it's in your head. You're in your head. That's what I mean. So anyway, that's... I'm really not trying to cry. I'm just trying to... That is like the state of what this is, is there used to be other paths for me to have an income alongside what I'm doing. But now all the paths are 40 hour a week jobs. Like, there's no good part time job that I could get that's flexible enough to be doing what I'm doing as well. And a lot of the reliable income paths. 51:42 can just be overnight. Oh, I mean, oh, I know dude. I got demonetized on tick tock. Yeah, I was making. I was making some decent money from tick tock and I don't know where they were just like it's unoriginal content because they flagged the podcast podcast clips. Yeah as me taking from YouTube. Yeah, and I appealed it and I was like, hey, this is my podcast. I'm the person in the clips. Yeah, this is see, see me. That's me and they rejected the appeal, so I'm not. I'm not able to monetize again and for another month and I go like how insane okay yeah. 52:09 like and that's what I'm saying is anyway. I'm not trying to cry. I really am grateful. This is my job. I'm not trying to complain, but that's also what I hate to when people are just like when I go. Well, we should figure out some better systems for artists to live like this and they go okay. Well, then just quit complaining and get a real job. Okay, delete your music playlist on Spotify. Never watch a movie again, never watch a TV show, don't watch a comedy special. Turn this podcast off, close your eyes, don't open them ever again. What are you talking about? Yeah, you know, like 52:38 Yeah, what are you talking about? Never go to a concert? Yeah, never. If you don't, if you don't think that this should be a real job, then don't go. Yeah, 52:47 I agree with you. I agree with you wholeheartedly anyway. Anyways, you want to talk about iodine? Yeah, how does iodine fix all that? Well, actually kind of hot in here, dude. Did they turn the AC off? It's possible if we have new neighbors and they like it hot. Yeah, and I and I'm going to tell them today, be like, put a hoodie on. uh So we have the data because during pregnancy, that's something we track is iodine levels because it's important. 53:14 And in 1971, the average iodine level for a pregnant woman was 327 micrograms a liter. Now, it's 144 micrograms a liter. So it's about cut in half. And we can see that in IQs across the country. It is a noticeable dip in IQs and theoretically, as we watch kids who were born after the year 2000 grow up, 53:42 I think there's a higher chance that we're going to start to see these effects with thyroid ah disease and deficiencies and potentially even goiters come back um really because our diets have almost completely removed these. um People are not eating I die soft. So all this to say and I do need to be very clear. There are some snake oil salesman online that are selling like supplements like you don't need supplements. Yeah. You can just get I die. So I just use I die. So when you cook there's been lots of taste tests that say that it's not noticeable. 54:12 some chefs will tell you you can tell they're wrong. It's not noticeable. Yeah, maybe a chef can tell maybe someone who's like an expert and they do it. They're around this all the time. They can't. There's pretending, but you're not going to be able to tell just cook with I saw you don't need to like go check it like just get enough like just eat whenever you use salt, use I saw and you're going to have enough and you're going to be fine and you're going to be smarter. Your kids are going to be smarter for it and you're not going to fall apart. I can't believe that's what the topic you chose. That's pretty wild. 54:40 when you're cooking, I guess here's who cooks anymore. By the way, here's what's I here's what's interesting. Here's what he does not in the US. Yes, I do you say I actually picture of your tonight putting a lean cuisine in the microwave is not cooking to be clear. Tonight, you eat lean cuisines tonight. I'm making sell people you eat link cuisines. I actually haven't a link when things in a while and I should eat link and scenes again. No, because I am eating pretty bad. Here's the thing. Here's the thing. I are not 55:08 good. Okay, no, no, no, I hate. I hold on. We didn't do our sponsor calorie. Oh, okay, yeah, we can do a response. I think and then I want to come back and close it with one more thought, but we can do our sponsor. What's our sponsor? Well, our sponsor this week was link was in until I hold it after that bit. So that's what they heard us record. All right, this week sponsor is this nineteen eighty six Ford f one fifty listed on Facebook Marketplace. It's currently thirty five hundred dollars. It is a 55:34 a four point nine liter six cylinder engine, four speed manual transmission. So that's kind of like a good thing to know. They replaced the brakes, the rotors, the master cylinder two years ago and this truck has not been driven much in the last several years. It's definitely like a vintage looking, you know, on you know, I could, oh that red leather interior. I will send all this to to Robert thirty five hundred dollars. How many miles? That's I was trying to find out a hundred and thirty seven 56:03 hey, that's pretty high, but workable. There was a guy who was on Conan O'Brien ah years ago because he got his uh engine over a million miles and I mean he meticulously maintained that thing, but he did so crazy right. Just work on it. It'll keep going and that's why every day I put I salt in my gas tank. 56:24 just to make sure that everything is going. Don't put sea salt in there. Yeah, that's not right. Don't put culture salt in there. It doesn't like that. Yeah. Yeah. Where's the thing? The this problem is confined pretty heavily to the US, a couple other Western nations, but pretty heavily to the US because most Western nations, when this whole all this stuff was discovered and we started iodizing salt, the process was like moved into law that all these nations have to iodize their salt when the United States 56:52 They just have to have this label underneath that that says this salt supplies iodide, a necessary nutrient where an kosher salt or sea salt says it does not. It just has to have a note that says this doesn't provide it. It doesn't have to. OK, I just have to tell you it has it or it doesn't have it. um And so the United States, people get the choice. um And because of that choice, we're all dumber. 57:20 I don't okay, so the next time you're cooking you open the freezer, you pull out the link was in box, put them at you peel back the you peel or do you puncture it depends on the okay, so you give it a little puncture with a fork. You put it in there beep beep beep put on some music, wait for your link with light a candle. 57:44 No, oh, relaxing music like a fiddle off. Okay. 57:51 Oh, like, okay. Let me try it again. 57:56 Roar shock! 58:01 maybe the next episode will be better. Hey, speaking of the next episode, you can watch it right now on patreon. We have next week. That was unavailable for the people who support us. It helps grow the show and also I could not even think of an episode to suggest for this old guy. I might not even suggest for a long time about this. How about Kellogg go look up Joseph Harvey Kellogg? That's because he thought that the gut was the central part of the whole life, and so he thought that your diet was very important. 58:30 Yeah, and then I was whatever shared the episode. You're not here. You've already exited out of it. Whatever dude. Thanks for listening to the show. We'll see you next week.


Have you ever heard of iodine? Most of us probably associate it with something doctors use during medical scans, or maybe that stuff in iodized salt. But what if I told you this seemingly small mineral plays a huge, often unseen role in our health and even our intelligence? Well, buckle up, because we’re diving deep into the fascinating world of iodine, and trust me, it’s a wild ride.

What Exactly is Iodine?

Iodine, at its core, is a chemical element, a true mineral. You might picture it as a solid, but in its element form, it’s actually a beautiful, purplish, heavy metal. And no, that doesn’t mean it listens to loud music; it means it’s super dense! This dense nature gives it some pretty cool properties.

One of the most interesting things about iodine is what happens when it interacts with starch. Ever seen those science experiments where iodine drops turn a potato dark blue or black? That’s iodine at work! This property is actually used in those pens that verify if a US dollar is counterfeit. Since paper is a starch, a real dollar (made of cloth) won’t react, but a fake paper one will turn dark.

The Irony of Iodine: Poison and Essential Nutrient

Here’s a mind-bending truth: iodine is both a poison and an essential nutrient. In large amounts, it can be toxic, just like pretty much anything if you overdo it. But in the right, tiny amounts, it’s absolutely vital for human life.

How tiny are we talking? The recommended daily intake is a mere 150 micrograms – that’s smaller than a teaspoon of salt! Any more than that, and you start running into risks. But without that small amount, our bodies can face serious health consequences.

The Thyroid Connection: Your Body’s Growth Regulator

The most important organ for iodine regulation in our body is the thyroid gland. This butterfly-shaped gland in your neck is responsible for creating crucial compounds like T3 and T4. These aren’t just fancy names; they’re essential for a whole host of bodily functions, with one of the biggest being growth.

  • For Kids: Iodine is super important, especially when you’re young and even in the womb, because it’s what helps create those T3 and T4 hormones that are critical for proper development.
  • For Adults: These compounds also regulate your metabolism, among other things.

Your pituitary gland acts like the general manager, sending signals to the thyroid when T3 and T4 levels are low, prompting it to produce more. The thing is, the pituitary gland is great at recognizing deficiencies, but not so much at knowing when there’s too much.

If your thyroid isn’t getting enough iodine, it can go into overdrive trying to produce these hormones, leading to various issues like weight gain and other health problems. In extreme cases, a historical condition called goiter can develop.

Goiters: A Visible Sign of Deficiency

Imagine a large, visible swelling in your neck – that’s a goiter. For most of history, people didn’t understand what caused these growths. Surprisingly, early treatments often involved sea sponges, which happened to contain a decent amount of iodine. People just didn’t realize why it worked at the time!

Geographic Disparities and Cretinism

Historically, our primary source of iodine came from the food we ate, specifically plants that absorbed it from the soil. The closer you lived to the ocean, the more iodine was naturally present in the soil due to rainwater. Move further inland, or live in areas once covered by glaciers (like parts of Northern Europe), and iodine in the soil becomes scarce.

This geographical disparity led to widespread iodine deficiency, particularly in regions like the Netherlands and Norway. Beyond goiters, a more devastating consequence of severe iodine deficiency, especially during pregnancy, was cretinism.

Cretinism used to be a leading cause of preventable intellectual disability, resulting in stunted physical and mental growth in children whose mothers were iodine deficient during pregnancy. The good news is, thanks to a major public health initiative, cretinism is almost entirely eradicated in the Western world today.

The Iodized Salt Revolution

Recognizing the widespread impact of iodine deficiency, particularly after World War I (when many recruits from inland areas like Michigan were found medically unfit to serve due to goiters), doctors proposed an ingenious solution: iodizing salt. Since everyone uses salt, it was the perfect vehicle to deliver this essential mineral.

This initiative took off in the 1920s, and while it had its early resistance (Morton Salt initially found it difficult to specifically iodize only for Michigan), the benefits soon became undeniable. Iodized salt quickly became recognized as a vital part of a healthy diet, leading to a remarkable public health success story.

IQ Boost: A Hidden Benefit

What’s truly astounding is a discovery made in 2013. Researchers analyzed data from military mental exams taken between WWI and WWII. They found that the average scores of WWII recruits were significantly higher – about 15 IQ points on average! This massive leap is attributed to the widespread adoption of iodized salt, meaning better brain development for an entire generation.

In fact, it’s estimated that iodized salt contributed to a whopping 180 million-point increase in IQ worldwide over the 20th century, primarily because fetuses were getting enough iodine for their brains to grow properly. Pretty incredible, right?

The Modern Iodine Crisis: Are We Getting Enough?

While we celebrated the success of iodized salt, a new challenge has emerged in the last 20 years: a noticeable increase in iodine deficiencies, particularly in the US. Why the rollback?

  • Dietary Shifts: Many chefs and home cooks have gravitated towards kosher and sea salts, which, unlike iodized table salt, typically lack iodine. How many recipes have you seen lately that specify “iodized salt”? Probably not many!
  • Dairy Changes: Historically, dairy was a significant, albeit unintentional, source of iodine. Trace amounts of iodine from cow feed and, more surprisingly, from idophor disinfectants used on milking equipment, found their way into milk. However, a push in the early 2000s to remove these chemicals from our food supply meant a key source of incidental iodine was lost.
  • Processed Foods: Many processed foods, while high in sodium, don’t use iodized salt. Plus, conscious efforts to reduce overall sodium intake, while good in many ways, can inadvertently reduce iodine intake if people aren’t choosing iodized options.

What This Means for You (and Your Kids)

If your mother was iodine-deficient during pregnancy, those developmental issues are often irreversible. Similarly, adolescent deficiencies can have lasting effects. However, as an adult, many iodine deficiency issues can be reversed through dietary changes or supplementation.

Here’s the thing: our average iodine levels during pregnancy have plummeted from 327 micrograms per liter in 1971 to 144 micrograms per liter today – almost cut in half. As children born after 2000 grow up, we might see a resurgence of thyroid diseases, deficiencies, and even goiters. We’re essentially creating a new generation with an iodine deficit.

The Simple Solution: Cook with Iodized Salt!

Seriously, it’s that easy. There are plenty of “health gurus” trying to sell you expensive iodine supplements, but you don’t need them. Just use iodized salt when you cook. Many taste tests have shown that, for the average person, there’s no noticeable difference in flavor between iodized and non-iodized salts. Chefs might claim they can tell, but for most of us, it’s just not true.

So, next time you’re in the kitchen, grab that iodized salt. It’s a simple, affordable way to ensure you and your family are getting this crucial mineral, supporting smarter brains, healthier thyroids, and preventing conditions that could otherwise sneak up on us.

It’s mind-boggling that something so basic can have such a profound impact, isn’t it? Our health, and even our collective intelligence, might just hang in the balance of a tiny crystal of iodized salt. Go figure!
