Why This “Zero Calorie Sweetener” Isn’t Zero Calories

    When I was Alex's age, I had very little of his on-camera skills or confidence, and to be honest, I'm a bit envious. I should also apologise for cutting out his usual intro and outro: go check out his channel to see them!

      Both you and Alex are entertaining and impressive. Age is irrelevant. What matters is developing skills and enthusiasm and putting those things to good use; it doesn't matter how long those things take to develop. Keep it up, both of you.

      How about Stevia? It's from a dried, plant extract, so it might have a bit less.

    In Australia, if a nutrient is present but is less than 1g, they can say "less than 1 gram", or in energy measurements, "less than 40KJ". I haven't seen any sweeteners that use that labelling though.

    I was perplexed why one croissant manufacturer makes croissants as 60g pieces or 5x37g family pack...
    And yet, on the back side, the nutrition values are written "per 100g" and "*per 1 serving (28g)*"
    Where did the 28g come from? Can that be similar thing to this, to fall into some category?
    How do you even make 28g pieces from 60g and 37g croissants?

    I'm not a sciency person, so I might have this wrong, but don't 0-calorie sweeteners have a different form of sugar that the body doesn't accept? I believe it's called the L-form of molecules

    DISCLAIMER: I hate to be the guy who appears to be siding with the evil corporations spreading their lies and deceptions but if you read patiently till the very end of my very long comment, you will find out that I am not actually the guy you thought I was.
    MAIN COMMENT: The thing is, Benedict's test doesn't really detect glucose. It will show its colors whenever it can react with aldehydes and alpha-hydroxy-ketones. These are the groups glucose happens to possess in just the right orientation for some good old Benedict's reaction. That is why sucrose is not readily detectable by Benedict's test despite being the most common form of natural sugar (having lots of Calories in it), because its aldehydes/ketones are not arranged in the proper way for the reaction and it can only be detected by Benedict's test after splitting it into glucose and fructose. However, glucose is not the only compound that has this property. Artificial sweeteners are often mimickers of the glucose in terms of their possession and orientation of aldehydes and ketone groups because the chemoreceptors for sweetness in the taste buds can be fooled by the same chemistry that gives colors to Benedict's solution when it reacts to non-sugars. Not to mention, the artificial sweeteners can not be processed by our body like usual sugars despite having certain chemical groups in order because the other parts of those compounds are very different from usual sugars, therefore gives off no energy within us, hence zero Calorie. Having said that, the kid really made an honest effort and I do not expect him to know/understand all the nuances of organic chemistry at his age. He especially deserves kudos for exposing the fact that the brand Splenda actually contains real sugar by reading the label and exchanging emails with the company because his experiment was not conclusive about it due to aforementioned reasons.
    FUN FACT: If you have too much vitamin C or normal dose of Cephalosporin antibiotics your urine will still give positive Benedict's test even if your urine is sugar-free because those substances are similar to glucose in terms of orientations and positions of aldehyde/ketone groups.

    The same thing applies with tic-tacs which are practically pure sugar

  • mspenrice
    mspenrice 8 months ago

    I feel like we stopped a bit short here. As in, we didn't then find out how many calories are in a sugar packet that produces equivalent sweetness in your cup of coffee. The Sucralose that Splenda also contains is many times sweeter tasting, gramme for gramme, than sugar, and itself has virtually no real nutritional value. The "real" sugar that they _do_ put in to the mix is probably to combat the rather candy-like, oversweet, metallic aftertaste profile that Sucralose shares with several other common artificial sweeteners, and provide both a more natural flavour plus the slight glucose hit that the body expects with sweet things in order to feel "satisfied" by them (and, curiously, that you somehow don't get so much with HFCS vs regular sugar, possibly because a lot more of it has to go through the liver first).
    I would expect a sugar packet that gives about the same sweetness to probably contain about 4 to 5 grammes of sugar, as it's 100% dextrose-maltose (ie, sucrose), and therefore 16 to 20 calories. So you're not losing all the calories that you would by not taking any sweetener at all (or a more completely artificial, and more synthetic tasting, alternative like Canderel), but you are saving something like 12 to 16 per serving. Which if you drink a lot of coffee through the day could easily add up to the difference between gradual weight loss and gradual weight gain. And is presumably why they're allowed to get away with calling it "zero calorie" in the states, because it's both so low compared to the sugar equivalent, but also low enough that the very act of making and consuming the beverage of which it is part probably burns up more calories than you take in as a result.
    I mean, otherwise an interesting and informative video, well presented. I just wanted more by the end ;) ... which is itself usually a good sign, and I know there's only so far school classroom science can go within a five minute time limit...

  • Overdrive02

    Okay okay, if I put five grams of Splenda in a drink, it should actually have 20 calories. From a legal standpoint, can I advertise it as 0 calories, because Splenda is 0 calories and 4•0 is obviously 0, or do I have to acknowledge it as 20 calories?

    The sweetener in Splenda is called "Sucralose". Sucralose actually has about 4 calories per gram - the same as glucose - with the difference beeing that it is 400 times sweeter. The dextrose only acts as a suport material to make it more authentic.

  • Igor Bednarski

    I have recently bought a bottle of diet coke and i have decided to take a look at the nutritional value... it says 0.4kcal/100mL. I don't think I have ever seen a product with actual zero calories, even the sugar-free stuff has at least 0.1...So it seems like it's possible to make money and be honest about the nutritional value. Why is this not the case in the USA?

    it can also be argued that gum is a negative calorie snack. though there is a tiny bit of sugar and flavoring in gums, which adds to the calorie count, the very action of chewing the gum consumes more calories than what the gum offers.

    the benedict test looks at the reducing capabilities of the solution, so some sugars are reducing agents (not all) and some things that are not sugars can give a false positive, it dosent change the conclusion, but it should be kept in mind

    Invertase breaks down sucrose, and is not made by humans, it’s made by yeast. So question A) is it possible the enzyme broke down dextrose and sucralose, sugars extremely similar with different bonds as sucrose, in a manner that humans would not be able to, and B) if the enzyme didn’t break down both of them, could Benedict’s reagent have just detected the sucrose or dextrose.

    It's not QUITE as scammy as this makes it sound. A typical packet of sugar is around 4 grams like a cube or teaspoon. A 1g packet of sugar could be marketed as zero calories, too. Splenda's 1g packets are designed to be a replacement for 2.8g of sugar but still have equivalent sweetness. That means it has a little less than 1/3 the calories for a given sweetness.

    Oh come on... Some mistakes and fallacies in this video. 1 gram of Splenda (content of one package) has the sweetness equivalent of 9 grams of sugar. Splenda's active ingredient is Sucralose, which is ~ 1000 times as sweet as sugar. So one gram of Splenda contains 10 milligrams of Sucralose. The rest in one package is filling material - and the case for Splenda carbohydrates. This is probably due to convenience and handling: Do you want to weight 10 mg of Sucralose every time you sweeten your coffee/tea or use the more convenient 1 g Splenda package with the 4 kcal extra from the filling material? Relative sweetness is the keyword here.
    Secondly, the Benedict's solution you were showing is not a specific reagent to detect glucose. It will generally detect reducing like glucose or lactose but also starch or maltodextrin. Non-reducing sugars like saccharose are not affected (of course you hydrolyzed it into the reducing sugars fructose + glucose using invertase). I was dissapointed that there were no further control experiments and a reference to the relative sweetness from your side.
