00:00:17,480 --> 00:00:28,400
Speaker 1: stuff works dot com where smart happens. Hi, I'm Marshall

8
00:00:28,400 --> 00:00:32,080
Speaker 1: Brain with today's question, why do they add iodine to

9
00:00:32,200 --> 00:00:35,040
Speaker 1: table salt? I have a box of salt in the

10
00:00:35,159 --> 00:00:38,760
Speaker 1: kitchen and it says iodizes salt, and then at the

11
00:00:38,800 --> 00:00:43,600
Speaker 1: bottom it says this salt supplies iodine and necessary nutrient

12
00:00:44,040 --> 00:00:47,440
Speaker 1: On the ingredient label at lists potassium iodine at a

13
00:00:47,479 --> 00:00:52,400
Speaker 1: concentration of zero point zero zero six percent. A quarter

14
00:00:52,520 --> 00:00:56,320
Speaker 1: chea spoon of salt or one point five grams therefore

15
00:00:56,440 --> 00:01:00,560
Speaker 1: provides sixty seven micrograms of iodine, which is out half

16
00:01:00,600 --> 00:01:04,320
Speaker 1: of the US recommended daily allowance for iodine. The main

17
00:01:04,440 --> 00:01:07,679
Speaker 1: reason that you need iodine is because of a gland

18
00:01:07,760 --> 00:01:11,399
Speaker 1: in your neck called the thyroid gland. The thyroid gland

19
00:01:11,440 --> 00:01:18,160
Speaker 1: produces two hormones, thyroxine and tri iodo thyroneine that your

20
00:01:18,200 --> 00:01:22,400
Speaker 1: body uses during metabolism. Without these hormones, you start to

21
00:01:22,440 --> 00:01:26,960
Speaker 1: feel tired, depressed, cold, weak, and so on. Iodine is

22
00:01:27,000 --> 00:01:30,480
Speaker 1: an important element in these two hormones, so without iodine,

23
00:01:30,760 --> 00:01:34,839
Speaker 1: your thyroid gland can't produce them. When start for iodine,

24
00:01:35,200 --> 00:01:38,240
Speaker 1: the thyroid gland also swells up, and when it does

25
00:01:38,319 --> 00:01:42,320
Speaker 1: it's called a goiter. Groiters can look pretty hideous. Your

26
00:01:42,360 --> 00:01:46,560
Speaker 1: body doesn't need or contain very much iodine. You might

27
00:01:46,680 --> 00:01:49,800
Speaker 1: have twenty or twenty five milligrams of iodine in your

28
00:01:49,960 --> 00:01:53,680
Speaker 1: entire body right now. However, in some parts of the world,

29
00:01:53,760 --> 00:01:57,640
Speaker 1: the soil contains no iodine at all, so plants contain

30
00:01:57,680 --> 00:02:01,960
Speaker 1: no iodine, and therefore iodine deficitiency is a big problem.

31
00:02:02,000 --> 00:02:04,520
Speaker 1: In the US, one part of the country that lacks

32
00:02:04,560 --> 00:02:08,560
Speaker 1: iodine is the Great Lakes region, So companies started adding

33
00:02:08,560 --> 00:02:12,680
Speaker 1: iodine to salt in the nineteen twenties to eliminate goiter

34
00:02:12,919 --> 00:02:16,560
Speaker 1: and thyroid problems. If you live through the Cold War,

35
00:02:16,760 --> 00:02:19,679
Speaker 1: you may have heard about the practice of taking iodine

36
00:02:19,760 --> 00:02:23,120
Speaker 1: pills during the threat of a nuclear attack. When a

37
00:02:23,200 --> 00:02:28,720
Speaker 1: nuclear bomb explodes, one substance it forms is radioactive iodine.

38
00:02:29,040 --> 00:02:32,959
Speaker 1: If you eat drink or inhale this isotope. Your thyroid

39
00:02:33,000 --> 00:02:35,920
Speaker 1: gland will concentrate it, and this can lead to a

40
00:02:35,960 --> 00:02:40,839
Speaker 1: thyroid damage or cancer. By taking an iodine pill, you

41
00:02:40,960 --> 00:02:44,639
Speaker 1: saturate your thyroid gland with iodine and prevent it from

42
00:02:44,680 --> 00:02:49,400
Speaker 1: absorbing any of the radioactive iodine. For more on this
