1
00:00:02,040 --> 00:00:07,200
Speaker 1: Welcome to brain Stuff from How Stuff Works. Hey, brain Stuff,

2
00:00:07,200 --> 00:00:10,040
Speaker 1: I'm lorn vogel Bomb, and it's time we talked about

3
00:00:10,080 --> 00:00:13,840
Speaker 1: movie theater popcorn. That's salty siren of the cinema. You

4
00:00:13,960 --> 00:00:17,279
Speaker 1: come without nutrition labels and sizes that defy sensibility. We

5
00:00:17,360 --> 00:00:21,000
Speaker 1: consume you in the dark. You're inadvertently vegan and gluten free,

6
00:00:21,360 --> 00:00:24,400
Speaker 1: but that still doesn't mean you're good for us. So

7
00:00:24,560 --> 00:00:27,920
Speaker 1: what the heck are you made of? Anyway? Meet movie

8
00:00:27,960 --> 00:00:32,120
Speaker 1: theater popcorns. Two main ingredients after popcorn, of course, flavor

9
00:00:32,200 --> 00:00:37,080
Speaker 1: call and butter flavored topping. Let's break those down. Flavor

10
00:00:37,120 --> 00:00:40,080
Speaker 1: Call is a proprietary seasoned powder that goes on the

11
00:00:40,120 --> 00:00:44,960
Speaker 1: corn before it's popped. It contains only four ingredients, superfine salt,

12
00:00:45,240 --> 00:00:49,040
Speaker 1: artificial flavor, and two synthetic yellow dyes that helped give

13
00:00:49,080 --> 00:00:53,479
Speaker 1: the popcorn it's violently yellow buttery ish color. Butter can

14
00:00:53,560 --> 00:00:56,480
Speaker 1: naturally be yellow because of a pigment and vitamin called

15
00:00:56,520 --> 00:00:59,200
Speaker 1: beta carotene that's found in the fresh grass that dairy

16
00:00:59,200 --> 00:01:02,480
Speaker 1: cows are sub times fed, or butter can be dyed

17
00:01:02,520 --> 00:01:06,200
Speaker 1: that color when cows are fat other things. Flavor Call

18
00:01:06,319 --> 00:01:09,959
Speaker 1: has zero calories and zero fat carbs and protein, but

19
00:01:10,240 --> 00:01:13,640
Speaker 1: being mostly salt, it packs a wallop in the sodium department.

20
00:01:14,200 --> 00:01:17,000
Speaker 1: One teaspoon contains a hundred and sixteen percent of your

21
00:01:17,000 --> 00:01:20,360
Speaker 1: recommended daily intake of sodium based on the average two

22
00:01:20,360 --> 00:01:23,800
Speaker 1: thousand calorie per day diet, and depending on the recipe

23
00:01:23,840 --> 00:01:26,280
Speaker 1: and the machine being used, you'd get about a third

24
00:01:26,280 --> 00:01:29,320
Speaker 1: of a teaspoon in a small popcorn, So heads up

25
00:01:29,360 --> 00:01:33,600
Speaker 1: if you're monitoring your sodium consumption. Next up that butter

26
00:01:33,680 --> 00:01:36,720
Speaker 1: flavored topping, which is what gets squirted out in pumps

27
00:01:36,760 --> 00:01:40,399
Speaker 1: if you ask for it. Warning betrayal alert. It doesn't

28
00:01:40,440 --> 00:01:43,320
Speaker 1: have any butter in it at all. What it does

29
00:01:43,360 --> 00:01:46,920
Speaker 1: contain is partially hydrogenated soybean oil, which is a trans

30
00:01:47,000 --> 00:01:50,240
Speaker 1: fat that falls into the category of bad fat. These

31
00:01:50,240 --> 00:01:52,200
Speaker 1: types of fats have been linked to heart disease and

32
00:01:52,240 --> 00:01:56,240
Speaker 1: other cardiovascular problems. The topping also has some beta carotene

33
00:01:56,320 --> 00:01:59,320
Speaker 1: that pigment I just mentioned. Beta caroteen helps add to

34
00:01:59,320 --> 00:02:01,880
Speaker 1: the buttery color and can, by the way, either be

35
00:02:02,120 --> 00:02:05,120
Speaker 1: naturally derived from plants or made in a lab. That's

36
00:02:05,160 --> 00:02:07,880
Speaker 1: the difference between it being labeled a natural versus an

37
00:02:07,960 --> 00:02:13,600
Speaker 1: artificial color. The topping also has tertiary butal hydroquinone or

38
00:02:13,720 --> 00:02:17,160
Speaker 1: tbh q, which is a synthetic preservative that keeps oils

39
00:02:17,200 --> 00:02:21,760
Speaker 1: from becoming rancid as they sit. And polydimethyl silazane or

40
00:02:21,919 --> 00:02:24,720
Speaker 1: p d MS, which is a silicone based chemical that

41
00:02:24,800 --> 00:02:29,240
Speaker 1: prevents foaming in hot oil. It's also been preliminarily shown

42
00:02:29,280 --> 00:02:32,000
Speaker 1: to help hair cells grow when applied topically, but that's

43
00:02:32,040 --> 00:02:35,079
Speaker 1: a different episode. Don't rub butter flavored topping on your scalp.

44
00:02:36,280 --> 00:02:39,120
Speaker 1: The final ingredient, the one that gives movie theater popcorn.

45
00:02:39,160 --> 00:02:44,680
Speaker 1: It's irresistible taste. Buttery flavoring, a non dairy mystery chemical

46
00:02:44,760 --> 00:02:48,880
Speaker 1: that mimics the taste of butter. This and the artificial

47
00:02:48,919 --> 00:02:52,520
Speaker 1: flavoring and flavor call are industry secrets, but they're probably

48
00:02:52,560 --> 00:02:55,640
Speaker 1: one of a few lab synthesized molecules that taste and

49
00:02:55,720 --> 00:02:59,239
Speaker 1: smell like butter. Diaceetyal as a to in a SETL

50
00:02:59,280 --> 00:03:03,480
Speaker 1: propionyl or similar Those first two that I mentioned are

51
00:03:03,560 --> 00:03:07,440
Speaker 1: compounds that are naturally created in old fashioned cultured butter

52
00:03:07,639 --> 00:03:11,320
Speaker 1: by the friendly lactic acid bacteria that helps solidify cream

53
00:03:11,520 --> 00:03:16,400
Speaker 1: into butter. Butter flavor is basically a tasty byproduct sort

54
00:03:16,440 --> 00:03:19,640
Speaker 1: of like with beta carotene. These compounds can be naturally

55
00:03:19,720 --> 00:03:23,840
Speaker 1: derived from farmed bacteria or synthesized in a lab. They'll

56
00:03:23,840 --> 00:03:26,959
Speaker 1: make that butter flavored topping taste almost like the real thing.

57
00:03:28,040 --> 00:03:30,280
Speaker 1: The real slap in the face, though, is that movie

58
00:03:30,280 --> 00:03:33,880
Speaker 1: theater butter flavored topping has twenty more calories per tablespoon

59
00:03:34,000 --> 00:03:37,080
Speaker 1: than real butter. So if you're a large bucket of

60
00:03:37,080 --> 00:03:40,120
Speaker 1: plain popcorn is about one thousand calories with just the

61
00:03:40,120 --> 00:03:42,360
Speaker 1: flavor call seasoning on it, and you choose to add

62
00:03:42,400 --> 00:03:44,960
Speaker 1: a minimum of three tablespoons of buttery topping, or as

63
00:03:45,040 --> 00:03:46,560
Speaker 1: much as six if you opt for a squirt in

64
00:03:46,600 --> 00:03:48,760
Speaker 1: the middle and a scort on the top, the large

65
00:03:48,760 --> 00:03:51,680
Speaker 1: bucket you nauch on while watching the latest blockbuster could

66
00:03:51,720 --> 00:03:55,800
Speaker 1: be more than two thousand calories. It definitely means that

67
00:03:55,840 --> 00:04:00,280
Speaker 1: movie theater popcorn is a treat. Everything in moderation. Oh

68
00:04:00,320 --> 00:04:03,040
Speaker 1: and a side note about diocetle, one of those butter

69
00:04:03,120 --> 00:04:06,800
Speaker 1: flavor compounds. You may have heard that it causes health problems.

70
00:04:07,040 --> 00:04:09,320
Speaker 1: That is a real thing, but the story got sort

71
00:04:09,320 --> 00:04:12,880
Speaker 1: of sensationalized. Factory workers who breathe in a whole lot

72
00:04:12,880 --> 00:04:15,800
Speaker 1: of dioceetle do have an increased risk of a particular

73
00:04:15,840 --> 00:04:18,640
Speaker 1: type of lung disease, and one guy who was popping

74
00:04:18,680 --> 00:04:20,919
Speaker 1: two to three bags per day for a number of

75
00:04:21,000 --> 00:04:24,760
Speaker 1: years successfully sued a bunch of microwave popcorn producers after

76
00:04:24,760 --> 00:04:28,880
Speaker 1: contracting that disease. But there's no known risk in eating

77
00:04:29,040 --> 00:04:32,120
Speaker 1: this artificial flavor or in breathing in the amount you'd

78
00:04:32,160 --> 00:04:34,280
Speaker 1: a realized from popping a bag of popcorn in your

79
00:04:34,279 --> 00:04:37,679
Speaker 1: microwave every now and then, and the Flavor Call brand

80
00:04:37,720 --> 00:04:40,560
Speaker 1: has come out as being dioceetle free. Good news for

81
00:04:40,640 --> 00:04:43,200
Speaker 1: movie theater popcorn. Do watch out for it as an

82
00:04:43,279 --> 00:04:51,120
Speaker 1: ingredient in vape liquid though. Today's episode was written by

83
00:04:51,120 --> 00:04:53,919
