Science Fact: Why Milk is better at hydrating than water · Do You F*cking Mind?

  Speaker 1: Fun science fact. And this is the fact milk is
• 0:17
  Speaker 1: better at hydrating than water. You heard it here. My
• 0:22
  Speaker 1: father once told me this fact, and he brought it
• 0:24
  Speaker 1: to me years ago, and I was like, that's fucking disgusting.
• 0:27
  Speaker 1: Who's going to be drinking a glass of like cow
• 0:30
  Speaker 1: teat juice when they're dehydrated? I can't think of anything worse.
• 0:34
  Speaker 1: Then fast forward maybe a year after he told me
• 0:37
  Speaker 1: that fact, I went for this long run. I was
• 0:40
  Speaker 1: living in Paris at the time, and I was so dehydrated.
• 0:43
  Speaker 1: Was such a hot day, and this run was very,
• 0:45
  Speaker 1: very long. I got back and I was you know,
• 0:47
  Speaker 1: when you're like unquenchable, your thirst is unquenchable. I was
• 0:51
  Speaker 1: so parched I kind of even begin to explain it.
• 0:54
  Speaker 1: You could only explain it through like interpretive dance. I
• 0:57
  Speaker 1: was so fucking parched. And then I looked in the
• 0:59
  Speaker 1: fridge was also milk. And I had had so many
• 1:02
  Speaker 1: glasses of water at this point, and I didn't want
• 1:03
  Speaker 1: to get like, you know, when your brain explodes because
• 1:06
  Speaker 1: you have so much fucking water. That's not a technical term.
• 1:08
  Speaker 1: I have a whole brain fact on water intoxication. It's
• 1:10
  Speaker 1: a thing. But I was like, I don't want to
• 1:12
  Speaker 1: drink fifty thousand liters of water. I'm just not quenching
• 1:14
  Speaker 1: my thirst. And so I saw the milk in the
• 1:17
  Speaker 1: fridge and I was like, I'm just going to take
• 1:18
  Speaker 1: my dad's advice and drink a big glass of milk.
• 1:21
  Speaker 1: And the moment I did that almost instantly, within a
• 1:23
  Speaker 1: couple of minutes, if not less, I was my first
• 1:26
  Speaker 1: had been quenched, so to speak. I felt amazing. I
• 1:30
  Speaker 1: didn't feel thirsty anymore. It was great. Why is that
• 1:34
  Speaker 1: the case? Okay, So, basically, one of the factors that
• 1:36
  Speaker 1: determines how well a drink hydrates you is the nutrient composition.
• 1:40
  Speaker 1: So obviously you need fluids in there. Milk is ninety
• 1:43
  Speaker 1: percent water, But you also did certain things that are
• 1:46
  Speaker 1: going to change how your body responds to that particular
• 1:50
  Speaker 1: fluid that you've ingested and is it going to hydrate
• 1:53
  Speaker 1: you or not. So, milk actually contains a lot of
• 1:57
  Speaker 1: different nutrients in it, such as lactose, proteins and fats
• 2:02
  Speaker 1: and also like potassium, sodium, all of that, and it
• 2:06
  Speaker 1: actually slows down the emptying of the fluids out of
• 2:11
  Speaker 1: your stomach and out of your system. And because it
• 2:13
  Speaker 1: slows it down. It keeps your body hydrated for longer
• 2:16
  Speaker 1: instead of the fluid getting emptied at really quickly and
• 2:19
  Speaker 1: you're paying it out. Okay, So the more you can
• 2:22
  Speaker 1: retain fluids, the more it gives your body the ability
• 2:25
  Speaker 1: to hydrate itself before it eliminates the excess fluids. Okay,
• 2:30
  Speaker 1: So obviously I'm just going to say this at the start. Fact,
• 2:35
  Speaker 1: you can't go past water as your main drink. I'm
• 2:37
  Speaker 1: talking about when you've been sweating a lot, when you're
• 2:40
  Speaker 1: really dehydrated, when you're reaching for those drinks that are
• 2:42
  Speaker 1: hydration aids, that have electrolytes, that have things like that.
• 2:46
  Speaker 1: You know, milk is also a really good option, is
• 2:48
  Speaker 1: what I'm saying. I'm not saying go and drink milk
• 2:50
  Speaker 1: as an alternative to water. There's many reasons why you
• 2:52
  Speaker 1: shouldn't be doing that. Or obviously milk is also really
• 2:55
  Speaker 1: high in a lot of other things. You probably don't
• 2:57
  Speaker 1: want to get all your calories from milk, but it
• 2:59
  Speaker 1: is a great agent to hydrate when needed, when you're dehydrated,
• 3:03
  Speaker 1: when you're sweating a lot, that kind of situation. Okay,
• 3:05
  Speaker 1: but don't replace water for milk. Not that you guys
• 3:08
  Speaker 1: would but just had to put it out there. So basically,
• 3:11
  Speaker 1: there's all these studies that show that when people were dehydrated, specifically,
• 3:15
  Speaker 1: I'm talking about people being dehydrated and they drank milk,
• 3:18
  Speaker 1: there was more retention of fluids, as in, they ped
• 3:21
  Speaker 1: less versus other drinks, in particular water and other sugaroo
• 3:25
  Speaker 1: drinks and things like that. Now, of course, there's going
• 3:28
  Speaker 1: to be limitations because we're looking at people that are
• 3:30
  Speaker 1: just dehydrated, and we're looking at smaller sample groups and
• 3:32
  Speaker 1: things like that, so there's always going to be limitations
• 3:34
  Speaker 1: in this study. But I think it's really interesting to
• 3:37
  Speaker 1: see how nutrients within the fluid can actually help you
• 3:41
  Speaker 1: retain the water. It's all about fluid like retention when
• 3:45
  Speaker 1: you're trying to hydrate. Because of that, milk is associated
• 3:48
  Speaker 1: with lower urine output versus water, you're more likely to
• 3:52
  Speaker 1: pee more when you're just drinking water versus milk, and
• 3:55
  Speaker 1: peing is good obviously, However, you want to give you
• 3:58
  Speaker 1: a body time to obs the fluids, and sometimes, depending
• 4:02
  Speaker 1: on the person and depending on the situation, you don't
• 4:04
  Speaker 1: have enough time and you're peeing up more than what
• 4:06
  Speaker 1: you're absorbing. Into your system. Now, another thing is when
• 4:10
  Speaker 1: you sweat, you release a lot of nutrients through your sweat,
• 4:14
  Speaker 1: including things like electrolytes. Okay, we lose potassium, we lose sodium,
• 4:18
  Speaker 1: we lose electrolytes in our sweat, so it needs to
• 4:23
  Speaker 1: be replenished. Just drinking water is not going to replenish
• 4:26
  Speaker 1: that quick enough, okay. So this is where those hydrating
• 4:29
  Speaker 1: agents come in, like a power rate or a gatorade
• 4:32
  Speaker 1: or something, or electrolyte drink. Now, firstly, what are electrolytes.
• 4:36
  Speaker 1: Electrolytes are essential minerals. Anytime you hear the word essential,
• 4:39
  Speaker 1: it means that it's essential for human health, like we
• 4:42
  Speaker 1: need these minerals for our body to actually perform. Okay,
• 4:46
  Speaker 1: So it's an essential mineral and its responsibility. The responsibility
• 4:50
  Speaker 1: of electrolytes is regulating fluid balance in the body. So
• 4:54
  Speaker 1: it helps you maximize the effects of fluid within the
• 4:56
  Speaker 1: body so you can stay hydrated for longer. Okay. Without electrolytes,
• 5:01
  Speaker 1: you're going to struggle maximizing the effects of fluid around
• 5:04
  Speaker 1: the body. Now, there were studies also done on non
• 5:08
  Speaker 1: dairy milk, and is that as good as milk for hydrating,
• 5:12
  Speaker 1: but there's very limited evidence. So there's when I say
• 5:14
  Speaker 1: there were studies done, there's not a lot out there,
• 5:17
  Speaker 1: not much evidence. And the reason why it's difficult is
• 5:19
  Speaker 1: because every single non dairy milk is quite different to
• 5:22
  Speaker 1: the next, so it's quite difficult. Unless you're comparing one
• 5:26
  Speaker 1: specific kind of non dairy milk to another, it's really
• 5:28
  Speaker 1: hard to get that information. But they also still have
• 5:31
  Speaker 1: a really high percentage of water. Non dairy milks like
• 5:33
  Speaker 1: nut milks and things like that, they've got a high
• 5:35
  Speaker 1: percentage of water. Of course they're going to be they're
• 5:36
  Speaker 1: going to be fine to hydrate, but are they as
• 5:38
  Speaker 1: good as milk, as far as potassium, electrolytes, all those things,
• 5:42
  Speaker 1: fats and all those things that we were talking about,
• 5:44
  Speaker 1: We're not quite sure. It doesn't look like it, but
• 5:46
  Speaker 1: again it's milk to milk dependent. And then of course
• 5:50
  Speaker 1: the last thing to know about it is that there
• 5:53
  Speaker 1: are calories. There's fats in the milk, and when you
• 5:57
  Speaker 1: have calories, and when you have fats, or when you
• 5:59
  Speaker 1: have more substance other than something that has no colories,
• 6:02
  Speaker 1: like water, it slows it down in the stomach. It
• 6:06
  Speaker 1: slows down the absorption as well. So you're getting this
• 6:08
  Speaker 1: kind of you're getting a replenishment of your electrolytes, your potassium,
• 6:12
  Speaker 1: your sodium, but then you're also getting it to slow
• 6:15
  Speaker 1: down within the stomach, and that slows down the absorption
• 6:18
  Speaker 1: into the body, which then slows down the elimination of
• 6:20
  Speaker 1: the fluids, which then allows the body to retain more
• 6:23
  Speaker 1: fluids because I've slows down that process. So the bottom
• 6:27
  Speaker 1: line here is drink water as your main source of hydration.
• 6:30
  Speaker 1: But if you ever find yourself dehydrated, really sweating a lot, parched,
• 6:35
  Speaker 1: unable to quench your thirst, it could be that your
• 6:37
  Speaker 1: body is struggling to retain the fluids that it needs.
• 6:40
  Speaker 1: It could be that it's lacking in potassium, electrolytes, sodium,
• 6:43
  Speaker 1: and things like that. And that's when you can be
• 6:45
  Speaker 1: reaching give your body a helping hand and reach for
• 6:47
  Speaker 1: something that's going to help hydrate your body properly. So
• 6:50
  Speaker 1: a milk is great, and then of course, like I said,
• 6:53
  Speaker 1: you've got the other hydration agents like actual those electrolyte drinks,
• 6:57
  Speaker 1: hydrolyte things like that, that's going to be great as well.
• 7:00
  Speaker 1: But again, water for every day intake is perfectly suitable,
• 7:05
  Speaker 1: perfectly fine. That's what we are made to drink. A
• 7:07
  Speaker 1: lot
