What Do Artificial Sweeteners Actually Do to Your Body?

September 10, 2019

Apparently, no calories does NOT equal no
consequences, and artificial sweeteners, like the kind you may find in diet drinks, may
be just as bad for you as sugar, with your brain and your gut responding in surprising
ways to that delicious, synthetic sweetness. The FDA has approved six artificial sweeteners
as a low-calorie or no-calorie options to help us curb things like obesity. So, they’re not sugar but studies have shown
that your body may still be reacting to them negatively. How is it processing these seemingly magical
compounds? The main theories come down to your brain
and your gut. Multiple studies have shown that sustained
artificial sweetener use can induce insulin resistance, and this probably involves your
brain. It could be when your tongue tastes something
sweet, your brain is expecting the physical presence of sugar, and tells your pancreas
to start producing insulin, which lets your body absorb the sugar. Only when there’s no sugar to absorb, you
still have the insulin in your body. Repeating this process every time you drink
a diet soda leads to insulin build-up with no place for it to go, and then, systemic
insulin resistance, the precursor to diabetes. Turns out, we can’t turn our brains off. It’s just trying to do its job, guys. Artificial sweeteners are anywhere between
200 to 20,000 times sweeter than table sugar, and aside from the insulin issue, we’re
still unsure how our taste receptors process these substitutes. Science does suggest, however, that your brain
can distinguish between the two. It knows when you’re eating real sugar,
and even though it still releases insulin in response to artificial sweeteners, they
light up a different neural reward pathway than real sugar. So at the same time that we’re exposing
our taste receptors to extremely, intensely sweet-tasting foods, These factors lead some
experts to say that we’re training our palate to crave sweeter and sweeter things while
our brain still isn’t receiving ‘true’ sugar satisfaction, so we’re just exacerbating
a sugar craving, not treating it. But it’s not just our brains, it could be
our guts too. Because, microbes!! Or at least a little bit. These faux sugars aren’t digestible, hence…no
calories. You literally just poop them out. But that means that those molecules just hang
out in your intestines, with certain microbes that can digest them. Those microbes can then trigger a ‘glucose
response’ leading to, you guessed it, insulin resistance. A changed gut microbiome in response to artificial
sweetener use could also produce hormonal changes in your body, quite possibly a hormone
that influences your appetite…and not in a good way. The researchers are careful to say, though,
that everyone’s microbiome is different, so the severity of these effects definitely
vary from person to person, and experts advocate a personalized approach to nutritional and
medicinal recommendations in this st area. And on top of all this, those who regularly
use artificial sweeteners may start to find healthy foods, even naturally sweet ones like
fruit, unpalatable because they’re so used to a more intense taste. Faux-sugar may help some diet-cola lovers
justify consuming extra calories that they wouldn’t otherwise, because they just drank
something with zero calories. And artificial sweeteners may prevent us from
associating a sweet taste with weight gain, training our brain to think we can eat whatever
we want with no repercussions. This is only the beginning of the ways that
artificial sweeteners may actually be contributing to the very epidemic they were supposed to
help fight: obesity, diabetes, and other weight-related diseases. So, that’s kinda nuts. We’re trying to bypass our body’s natural
mechanisms so we can eat super sweet stuff with nothing bad happening but it looks like
nature is not letting us get away with that. That information is a little tough to swallow,
but rest assured that we here at Seeker will always keep your science craving satisfied,
so subscribe so you can always decide what not to drink, and check out my other video
on how your gut controls you brain. Fun Fact: The first artificial sweetener was
discovered in a lab accident. The scientist spilled a food preservative
on his hand and forgot to wash his hands before lunch. Spoiler: it was sweet I’m Maren. Thanks for watching!

    I used to drink diet coke because regular coke turned out to be too sweet and not sharp enough for my tastes. I was already relatively resistant to sweet things even as a child (thus never experiencing a sugar high, ever), so I mainly enjoyed other flavors instead not based on sweetness, because there was always that certain point where I could no longer taste sweet stuff in foods. The artificial sweetener did a bit of damage at first, enlarging the capillaries in my face was my first clue, to the point where I looked like a severe sunburn victim (and felt like one, too). I never experienced this with any other food or drink before I got into diet coke, so it was kind of obvious what caused it. The condition is called Rosacea, and things like broken blood vessels and pimples may also occur when it gets severe. I stopped when I realized diet coke was doing it to me, and I can't really enjoy most coke drinks anymore without the Rosacea flaring up violently.

    Now I just drink (regular) Ginger beer and coffee. Artificial sweeteners may be seen as a good idea, but I can assure you, its not the best idea.

    Also the sweeter u only metabolize 2% of it the rest is shat out… So hence its under 1cal a drink

    Ha, it is very unlikely that artificial sugar will cause you to produce insulin so you can mention that, also you can’t state “aRtIfIcAl SuGaR iS tRaInInG oUr BrAiN tO wAnT sWeEtEr AnD sWeEtEr ThInGs”, that’s not significant because it will be no different from real sugar in that sense, however if you have any form of self control it is no problem. Nag and whine little fools but it is a low calorie option which does play into dieting regardless of what people say. If you use in moderation and have no pre existing conditions, you will be much better off consuming artificial sweetened drinks and gums than real sugar options. Also honey, honey, honey People are different than test mice who have been exposed to pure sweeteners equivalent to thousands of artificially sweetened sodas in a short period of time, no one will get cancer from the soda alone, you’d sooner suffer from acid intake and many other problems. Yeah water is better but soda is a tasty treat which I do find unnecessary but I hate the people who hastily grab a small bit of research and run with it.

    Ooo and I’m glad they didn’t mention it, 0 calorie sodas actually do have calorie and I hate it as an argument because it’s almost always less than about 10.

    What happens if you consume artificial sweeteners along a heavy carb diet?

    For example, I eat a big mac(high on fat/carb/pretty much everything) along with diet coke.
    My body will still get its sugar from the burger (so no excess insulin in my body) and I don't need to worry about sugar in my drink.
    Will this still be an unhealthy choice?
    I've been doing that for a while, only drinking diet drinks along with heavy meals.

    Sweetness measurement is like bitterness measurement which is measured in IBU's International Bitter Units….something can technically measure higher but taste much less bitter. Testing chemical constituent levels and inferring levels in a lab isn't the same as the feels like on the tongue. People universally prefer real sugar to artificial sugar and it is well known that many people never can develop a taste for artificial sweetners. Because they universally taste less sweet.

    There are so many maybes and could be's in this video it is almost like one of the workable fusion, other dimension, multiverse, wormhole or warp speed videos in that it it hits the ear like science fiction that could in pure theory one day actually work and be non-fiction, but today, right now it just doesn't happen that way.

    In college, they teach you a (sort of) joke idea to conceptualize the 3 laws of thermodynamics. It goes as follows: 1) You can't win. 2) You can't break even. And, 3) You can't get out of the game. Who knew that these unbreakable laws also applied to dieting? It's just not fair, I tell ya! Not fair at all. Sometimes I think the only way to lose weight is to quit your job, devote 12 hours a day to exercise, & stop eating all together. Either that, or have some evil guy curse you with, "*Thinner!* 𝙍𝙞𝙠𝙠𝙞 𝙏𝙞𝙠𝙠𝙞.

  • Reply Richard Deese August 24, 2019 at 10:05 am

    NOTE: While this list can hardly be exhaustive (of course), I think you should have mentioned Rebinia. It's steviol glycoside, or rebaudioside A; it's 200x sweeter than sugar (which is a common sweetness level); and it comes in granulated form, which can be used as a normal sweetener for drinks, etc. It can also be substituted 1:1 in baking, and is non-caloric as well. [Hey, since they're all bad for you (as it turns out per this video), we may as well include a nice popular one that's handy.] I use it to sweeten tea and Kool-Aid. Coca-Cola actually owns the exclusive rights to use it in beverages, but it's sold in re-sealable pouches (like shredded cheese) as Stevia. It's also sold as Truvia and as PureVia. Honestly, it's the only one I like; can't stand the others! 𝖙𝖆𝖛𝖎.

    P.S. – And no, I don't work for any of those companies. Never did. Just like the stuff, that's all. I'm a super-taster. Can't fool me. I can identify sweeteners by taste. I can distinguish between Coke, Pepsi, and RC… blindfolded. That's just the way it is. 𝖙𝖆𝖛𝖎.
