Artificial Sweetener Xylitol May Also Be Linked To Heart Attack and Stroke, Study Finds (cnn.com) 67

CNN reports that the low-calorie sweetener xylitol used "may be linked to nearly twice the risk of heart attacks, stroke and death in people who consume the highest levels of the sweetener, a new study found..." In 2023, the same researchers found similar results for another low-calorie sweetener called erythritol, which is used as a bulking sugar in stevia, monkfruit and keto reduced-sugar products. Additional lab and animal research presented in both papers revealed erythritol and xylitol may cause blood platelets to clot more readily. Clots can break off and travel to the heart, triggering a heart attack, or to the brain, triggering a stroke.

In the new study on xylitol, "differences in platelet behavior were seen even after a person consumed a modest quantity of xylitol in a drink typical of a portion consumed in real life," said Dr. Matthew Tomey, a cardiologist at Mount Sinai Fuster Heart Hospital in New York City, who was not involved in the study... "Through their work, the investigators have shined a light on the safety of sugar substitutes. There is more to learn," Mount Sinai's Tomey said. "In the meantime, it is worth remembering that sugar substitutes are no substitute for a sincere commitment to the several elements of a healthy diet and lifestyle."

Tomey added that the experiments "are interesting but alone do not prove that platelet abnormalities are to account for a linkage between xylitol and clinical events." But CNN notes that the researchers began by analyzing over 3,200 blood samples — and then also gave volunteers a typical xylitol-sweetened drink to see how much in increased their glucose levels. "They went up 1,000-fold," senior study author Dr. Stanley Hazen told CNN.

His study adds that the World Health Organization warned consumers in 2023 to avoid artificial sweeteners for weight loss and called for additional research on the long-term toxicity of low- and no-calorie sweeteners.

            Xylitol is very rarely used in food. It is expensive and less sweet, and almost only found in dental-related products because it is fantastic for dental health. So that means toothpastes and mouthwashes, which are never swallowed. And gum and mints, of which one doesn't usually consume much volume.

            As for other sugar alcohols, yeah, they can be pretty yucky.

Because you're either buying full sugar American food, or "keto"-labeled food which is always laden with these sugar alcohols. Finding stuff in the middle (which is low carb, say without a ton of added sugar, but ALSO without a ton of these sugar alcohols) is freakin impossible.

      “When you eat sugar, your glucose level may go up 10% or 20% but it doesn’t go up a 1,000-fold,” said Hazen, who also directs the Cleveland Clinic’s Center for Microbiome and Human Health.

      but missed the one immediately prior:

      “We gave healthy volunteers a typical drink with xylitol to see how high the levels would get and they went up 1,000-fold,” said senior study author Dr. Stanley Hazen, director of the Center for Cardiovascular Diagnostics and Prevention at the Cleveland Clinic Lerner Research Institute.

      Yeah, you can learn to tolerate unsweetened flavored seltzer water and I'm sure some people have even convinced themselves they like the stuff. It'd still taste a lot better with some sweetener added to it.

        Speaking of evolution, there's a theory (though it's disputed) that the reason that so many plants have evolved a wide range of non-caloric sweeteners (the vast majority of which aren't on the market and you've almost surely never heard of them) is to game the system. Animals evolve to crave sweet things for the calories; plants evolve to put non-caloric sweeteners in their fruits so that they don't have to invest the energy to make sugar.

        It sounds logical, but there are some hitches in it - the evidence f

        • The problem with that theory is that non-caloric sweetners aren't non-caloric. Humans can't digest them, so we don't get calories from them, but they still store energy and have a cost to produce. In many cases, that production cost is significantly higher than the simpler glucose-fructose sugars that we can digest.

            In many cases, that production cost is significantly higher than the simpler glucose-fructose sugars that we can digest.

            This is simply not true. The amount of most non-caloric sweeteners needed to make a fruit sweet is microscopic compared to the amount of sugar to do so.

        • Animals evolve to crave sweet things for the calories; plants evolve to put non-caloric sweeteners in their fruits so that they don't have to invest the energy to make sugar.

            In their fruits? For seed dispersal. That's the reason why most fruits exist. They're there to be eaten, or at least carried around with intent to eat (and occasionally dropped / lost / hidden and forgotten).

            As a general rule, plants can't walk, fly, swim, etc. Moving their descendants around is a challenge for a sessile organism.

            It's when sweeteners are found in parts of the plant other than fruits and flowers that the theory starts to break down.

It's typically used as a sugar substitute in products where sugar provides bulk in addition to sweetness, such as sugar free candies.

      Xylitol isn't artificial, it's a naturally occurring sugar alcohol.

      More than that, it's an intermediary molecule made while metabolizing different sugars, and it's a totally naturally occurring chemical in various fruits. But don't say the word "chemical" to the food religion, it scares them. Not that they'll eat anything containing xylitol anyways, because they won't eat anything with an ingredient they can't pronounce. But it's not all bad -- the good news is we can starve them all out simply by showing them the ingredients of basically everything. Like natural organic bananas for example:

      https://i.kinja-img.com/gawker... [kinja-img.com]

      Just look at all of the food dyes in it -- they know that stuff is bad for them. Oh and it has all three of the ingredients that make up aspartame. Show them this and they'll never eat a banana again. Just don't tell them that all of these stupid rules they follow are really just marketing crap made up by the very food industry they despise, generally they pay pop culture magazines to invent completely meaningless shit terms, like the word superfood, which has no scientific basis at all and none of those assholes can even agree on what the word means.

    • Lead is naturally occurring too. Sounds like an odd comparison BUT: We know that ideally we consume no lead in our lives, too much is a bad thing; Xylitol is also natural, ok, but perhaps consuming any significant amount is bad for you too. Salt is also a natural product but you must control your intake or bad things happen there too.

      Calling something a natural product doesn't mean anything at all.

            Yes. You can extract the Xylitol (or Xylose) with hydrogenic cyanide - at least that's how Emil Fischer & Co. did it in 1891, when they discovered Xylitol in birch tree bark.

      Sure, it's "natural" but consuming large amounts of it, just as with sugar itself, is definitely not.

      In other words, swapping out one food item which we have refined (thus removing qualities that mitigate it's worst properties healthwise) and consume in extremely unnatural quantities for another for which we have done the same has never seemed like a winner idea to me.

    In Finland, xylitol isn't used so much as a sugar substitute / sweetener, but rather an after-meal “drug” to fight dental caries in the form of chewing gum or tablets. Its effects were studied here extensively in the 1970s, and we now know it works best in pure form, i.e. not mixed with other sweeteners.

    Growing up in the 1980s, the chewing gum format was quite popular due to extensive campaigning, but I personally didn't like chewing things that much. In the late 00s I started taking xylitol tablets after meals, and since then my teeth have been in much better shape. The tablet also works as a psychological marker for the end of a meal, so it helps maintain a discipline of a few solid meals per day instead of continued snacking.

    Like a lot of sugar alcohols, xylitol has a laxative effect, but it's not noticeable with the recommended doses, which is about 5 g per day. So the 30-gram dose mentioned in this study isn't very realistic.

    I would also note that dental caries (and other infections of the mouth such as gingivitis) is linked to wider health problems including heart issues. So I won't be giving up my xylitol tabs any time soon.

    I'm having trouble finding the page again in my browser history, but I was researching mouthwash ingredients and found a paper guessing that a statistically significant increase in hospital deaths after a certain mouthwash ingredient was used was due to NO regenerating bacteria being destroyed in the mouth. It was just a theory in the paper that someone else needs to investigate.

    Think nitrates/nitrites to nitrous oxide (saliva and digestive tract being involved) which is a blood vessel dilator and is used as a medication for heart conditions ('nitro pills'). If we suddenly drop the incoming levels, in a person already sick in other ways (being put on a ventilator, or other reasons to be in a hospital)... it's not too surprising they're more likely to have bad heart problems just afterward.

    This might be the same thing. With bacteria not able to eat the Xylitol being a reason it prevents tooth decay. Remove all food for something and it'll die. Any ancillary things it helped with will stop too.
