      +NNJ Studios Yes, it is incorrect. They should have used "its" because "it's" is a contraction for "it is", so the possessive form has no apostrophe.

      +NNJ Studios people don't notice the difference between *its* and *it's* ( I didn't untill reading this comment) and since language isn't law, but a naturally evolving element of humanity, soon it will both be correct. its allways refers to a property of something (like in this case) and it's is a subtraction of it has
      (i.e. "*it's* (it has)been a good day for science" or "look at the furr of my cat, "its" hair (the hair of it) is stripey so it must be a female")
      (ps did need to say naturally or natural? idk & idc really)

    If someone is wondering... just because sucralose has chlorine does not mean it is toxic. Chlorine by itself it toxic, and also apart of SODIUM CHLORIDE, or table salt. So you already ingest it a lot in your everyday proceedings.

      I´m not chemophobic. Actually, I try to fight chemophobia.
      But, let´s say, I´m not that happy when I knew about chlorine on sucralose.
      The point is not the element by itself, but the remembrance of chlorinated pesticides. But anyway, if after passing all tests and regulations it was approved, let´s presume it´s safe.

    You forgot sodium cyclamate. It may still be banned in the US, but it's sold in other countries under names like Sucaryl (or Sugar Twin in Canada), often in a mix of 10 parts cyclamate to 1 part saccrine.

      @nickPOPmusic 9 років тому

      PaganArwen actually, Xylitol simply neutralizes some of the acidity caused by bacteria breaking down sugars. Don't let that stop you from buying xylitol gum as a preventative measure against cavities though, because it can be very effective for maintaining healthy enamel.

    Saccharin doesn't cause cancer. It certainly does cause bladder cancer in rats, but this is one of those cases where a poor animal model was chosen.
    The reason for this, as it turns out, is that rats have different environments in their bladders than humans do. As a result of different proteins and pH they produce things in conjunction with saccharin which cause damage to the lining of their bladder; repeated damage to your bladder (or anything else) will raise cancer risk due to more cell division and other factors.
    As it turns out, this does not happen in humans, so saccharin is, as far as we can tell, harmless. This is hardly the only chemical compound where some animal models are poor choices; humans eat all sorts of things which cause toxic effects in critters.

It's a different disaccharide and it can only be made artificially - it doesn't exist in nature as you assertively mention none compound in nature is chlorinated. If possible a correction should be made.

    About the last warning on the video about the calorie count on the sweet foods, the interesting thing is that in this year it has been found that we have another kind of taste receptor for carb, and with that, we can't trick our brains into swallowing low calories food, as it knows we are not getting enough energy, and when we eat proper food, it also knows.

    I have two questions. Feel free to chime in if you know! First, Hank kept giving examples of how much sweeter some artificial sweeteners are to sugar, "sucralose is 600 times sweeter." What is the science of measuring sweetness? How would one even get the number 600? Second, what does the manufacturer cut stevia with to lessen the sweetness? I hope I explained my questions well enough to be answered. Thanks to anyone that can help!

    • @stevenbudaya2140
      @stevenbudaya2140 11 років тому

      Just a blind guess here, but maybe it's similar to how we measure how spicy a chilli pepper is? a ghost pepper is more than a hundred times(if i remember correctly) more spicy than Jalapenos, and we don't burn alive eating a ghost pepper so maybe 600 times higher in a scale of some sort? kinda like Scoville scale for spicy level.

    • @RMoribayashi
      @RMoribayashi 10 років тому

      Stevia extract (when not used as a liquid) is cut with dextrose and/or maltodextrin. Coca-Cola's "Truvia" is different. Since they could not patent the stevia plant itself they created a patentable process to isolate one of its components. This is then cut with erythritol, a sugar alcohol derived from corn. Unfortunately the part of the stevia plant they isolated has a bitter aftertaste, so vanllin is added to mask it. Fine for cola but it leaves a noticeable artificial vanilla flavor in other foods.

    • @XfishX
      @XfishX 10 років тому +1

      There's a device called a refractometer that determines the sugar content of liquids.
      www.homebrewstuff.com/refractometer-how-to
      en.wikipedia.org/wiki/Brix
      It's a good idea to know how much sweeter an additive is than sucrose (which is the standard/control the other sweeteners are compared to). Knowing that sucralose is 600x sweeter will make you, or at least should make you, use less because it takes a smaller amount of sucralose to equal the same sweetness as sucrose.

    • @RMoribayashi
      @RMoribayashi 10 років тому

      The only way to compare them is mass human testing. Researchers increase the concentration of a sweetener until *any* change in taste is detectable by subjects. That is called the "threshold value" and is what they use to compare sweetness.

    Right. Lasting soreness is a good sign you worked out enough that your body will be triggered to repair and generate new muscle.
    The "burn" is only a good sign you're working hard though, not muscle build up. It's merely that your muscle was worked enough that all oxygen was used for aerobic energy production and, to keep moving, the cells switched to anaerobic energy production which doesn't use oxygen, but ends in by products that need to be dealt with afterwards, including lactic acid.

    I'm​ interested in understanding why many people believe there is a link between aspartame and MS. I read something about aspartame increasing free radicals & oxidation...

    In terms of meat and meat products? Varies with the person, location, expenditure ect. But roughly; a serve of lean red meat 2-3 times a week, a serve of lean poultry/seafood 3-4 times a week, 2-3 serves of dairy products (milk, cheese, yogurt) a day. Eggs can also be used to replace some of your intake of protein sourced directly from animals.

    Great video Hank, thank you. Only thing I want to say it that I would have liked if you suggested looking at what other regulatory bodies have to say about artificial sweeteners, as not everyone lives in the US or feels confident about the FDA maintaining a independent science based position.
