But despite their ubiquity, the scientific verdict on whether or not they pose health risks ping pongs back and forth. Every so often, though, a study is published with a conclusion so shocking that it forces people to reassess their pantries. A Feb. 27 [study](https://www.nature.com/articles/s41591-023-02223-9.epdf?sharing%5Ftoken=houAjaO9X57s5sq3spY0pdRgN0jAjWel9jnR3ZoTv0MTnVt%5FYzm2YDkmKtSZJOysYZlROr0ymfAdj9yPHH8bMVWpKjhPzPeMT8zTG9DpNMmnfRfOqNqOH8PhwI2X9sxfHMa-Tpawl-dyIWq9WdTUO2lqDJWIHLoFK3aG5AGi1YiCVJfwcnRAr1mBYU8sTfyzRK88UHhEDnrmYTIJu6F4AQ%3D%3D&tracking%5Freferrer=www.cnn.com) published in the journal _Nature Medicine_ now seems to have dealt such a blow to the sweetener erythritol, with data that suggest a connection between the ingredient and cardiovascular events such as clotting, stroke, and heart attacks. But before you clear your shelves of all erythritol-containing products, bear in mind that no single study—including this one—should be taken as the final word on whether a product is healthy or not. The research is still evolving. The researchers recruited multiple groups of people with preexisting cardiac risk factors across the U.S. and Europe, and tracked their health over time after taking blood samples to measure the amount of various compounds in the body. Stanley Hazen, director of the Center for Cardiovascular Diagnostics and Prevention at the Cleveland Clinic Lerner Research Institute, says that his team had no real intention to study erythritol, and instead stumbled across their new findings. “Our original intent was to see if we could find compounds in blood whose levels predict the future development of heart attack, stroke or death,” he says. “When looking at the data, the very top-ranking compound…was erythritol.” Of the 4,000 people included in the study’s dataset, those who had high levels of erythritol in their blood were more likely to suffer a major cardiac event within three years than those with lower levels. --- ### More from TIME --- The study includes multiple other experiments to elucidate the connection between erythritol and heart disease—including feeding the sweetener to mice, which the researchers found promoted the formation of blood clots, and feeding it to eight people, which showed researchers that it was still present in blood plasma after a day of fasting. Further experiments, which included exposing blood, platelets, and plasma in a lab to erythritol, all showed the same clotting risk; on washed human platelets, an increased collagen “stickiness” was almost instantly apparent. The amounts of erythritol they tested in these lab experiments were “completely within the range of what we’re seeing in the \[blood\] circulation of patients,” says Hazen. “And the effect is quite rapid. Just being in the presence of erythritol for minutes was all that was necessary to change platelet function and make them more prone to clot.” **Read More**: [_Magnesium Supplements Are a Buzzy New Sleep and Anxiety Aid. Do They Work?_](https://time.com/6258780/magnesium-glycinate-sleep-anxiety-tiktok/) Erythritol is considered one of the more “natural” sugar substitutes that has emerged as an alternative to the artificial options popularized throughout the last half century. This older group of synthetic sugar substitutes includes sucralose (found in the original version of Splenda), saccharin (found in Sweet’N Low), and aspartame (found in Equal, Nutrasweet, and more). While these artificial options are generally considered to be safe in small amounts, studies on animal models (and some observational research in humans) have linked them to [varying heath risks](https://www.biotech-asia.org/vol18no2/artificial-sweeteners-and-their-health-implications-a-review/). Aspartame, for instance, [has been found](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8227014/) to have a potentially causal relationship with cancers, while long-term saccharin consumption [has been tied to](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6843803/) obesity, diabetes, and other conditions in animal models. Over the last decade or so, food manufacturers have started favoring more “natural” types of non-sugar sweeteners to help skirt these potential health concerns. This category includes sweeteners such as stevia leaf and monk fruit extracts, along with erythritol and other [sugar alcohols, or polyols](https://www.nytimes.com/2022/11/15/well/eat/sugar-alcohols.html)—recreations of low-calorie substances found in fruits and plants. (If you shop at a typical grocery store, there’s a pretty strong chance you have something with erythritol in your kitchen right now.) Erythritol is also popular as a keto-friendly sugar substitute in baking, as it’s known for having a less artificial aftertaste than some other sweeteners. Despite thorough research, erythritol and other polyols have [not been previously linked](https://academic.oup.com/advances/article/10/suppl%5F1/S31/5307224?login=true) to any long-term health risks or disease, though in the short term they can cause laxative effects and other gastrointestinal issues. But when figuring out how concerned to be about the current study, it’s important to know that the appearance of erythritol in the blood before a cardiac event doesn’t necessarily mean that erythritol is causing the event. [Previous research](https://journals.lww.com/co-clinicalnutrition/Abstract/2020/09000/Mammalian%5Fmetabolism%5Fof%5Ferythritol%5F%5Fa%5Fpredictive.3.aspx) has found that excess erythritol—which is also made and metabolized by the human body—tends to stick around in [higher concentrations](https://academic.oup.com/cdn/article/5/Supplement%5F2/515/6293650) in blood before a cardiac event, pointed out London-based dietitian Nicole Guess in an Instagram [post](https://www.instagram.com/p/CpNiNacoOsG/?igshid=MDM4ZDc5MmU%3D) about the study. Erythritol in the body can be an indicator for cardiometabolic disease, but it’s unclear whether that volume is determined by diet or by what the body has that it just isn’t getting rid of. **Read More**: [Is There Really No Safe Amount of Drinking?](https://time.com/6248439/no-safe-amount-of-alcohol/) Erythritol production in the body has [even been shown](https://www.frontiersin.org/articles/10.3389/fnut.2022.953056/full#:~:text=10.3389%2Ffnut.2022.953056-,Erythritol%20synthesis%20is%20elevated%20in%20response%20to%20oxidative%20stress%20and,phosphate%20pathway%20in%20A549%20cells&text=Background%3A%20Erythritol%20is%20a%20predictive,pentose%20phosphate%20pathway%20%28PPP%29.) to increase when a person is under oxidative stress—a state that often leads to sickness, says Dr. Idrees Mughal, a British physician with a masters in nutritional research. These potentially confounding variables mean that the scary headlines about erythritol don’t always match the more complicated reality, since correlation is not causation. “I think the major problem with the media outlets was simply the statement that was being made, which was the consumption of this sweetener was the reason for the increased risk of the strokes or the heart attacks,” he says. Experts have also taken issue with the fact that the dataset used for the analysis included only people over the age of 60, all of whom had preexisting cardiovascular diseases or qualified as high risk for developing them. Of course, definitively linking erythritol intake and heart disease would be difficult to do. “You’re not going to easily do a randomized trial where your intent is to try to see whether or not you cause a heart attack,” Hazen says. So should people give up their erythritol-containing snacks? “At this point, I’d argue to certainly avoid erythritol, and not to be worried or upset about very modest amounts of sweeteners that are natural,” such as honey or pure sugar, says Hazen. In his opinion, reducing the intake of sweets is safer and more effective than using a sugar substitute. For those looking to lose weight, for instance, the data [do not bear](https://www.frontiersin.org/articles/10.3389/fnut.2020.598340/full) out that skipping sugar in favor of low- and no-calorie alternatives actually contributes to weight loss. Yet eating too much sugar has [health risks](https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/sugar/how-too-much-added-sugar-affects-your-health-infographic), Mughal adds, and in his opinion, “the associated risks of excess refined sugar far outweigh any of the sweeteners.” The bottom line? Like so many foods that are the focus of nutrition research, more research is needed before you purge your pantry. ## Transcript What we discovered is that aging is very likely, a Corruption of the software of the body. So that as we get older, the software doesn't function pretty well. Things, slow down, break and we get diseases. In this new work, we show that we can actually reverse that process by tapping into a backup copy. Rebooting the software into that old computer opening up the possibility that one day we can rejuvenate our whole body. Dr. David Sinclair, co-director of the Paul F Glen Center, for biology of Aging research at Harvard Medical School describes a groundbreaking method that could speed up or reverse, the aging of cells in the body at least in my does an old theory that mutations Drive aging. And it's true that our DNA does get damaged and it does lead to changes in our genetic code. What we're proposing in this new study is that there's another type of information in the cell in our bodies, hold the epigenetic information. And that's the information that we think is a large driver of the aging process Sinclair says that the process of Aging work. Similarly, to the way that software programs operate off Hardware, sometimes software becomes corrupted, and needs a reboot through the process of gene therapy cells in the body, can be rebooted to restart the backup copy of epigenetic instructions. The epigenome consists of chemical compounds, that Mark cells and give them instructions for which gains turn on and wish to keep silent. This inferior race is corrupted signals that can cause cells to Asian. Making them useful yet, but we believe that there's a universal process that we've tapped into that works, not just in my house, but probably in every human on the planet and we all have the same program that allows households to you. You rejuvenate it in my so we reverse the age of their brains and they get their ability to learn. Again, that's what with finding is that there's a universal backup copy of useful information and all animals and probably in us as well. The process is still in its infancy. So there's still a lot to be figured out Sinclair says that his team is already beyond the next step to lab test. The system or non-human primate human neurons skin in fibroblast cells. While this method won't stop the body from aging is a whole, it could Target specific areas to reverse the effects of disease. The first disease that I want to trade is Blindness. We are very easily able to reverse blindness in mice, and the results from the non-human primate. Studies will be out in the next few months. So we're very excited about being able to treat diseases. But if you allow your imaginations, run wild, what it could mean is that we can reverse the age of any cell in any tissue in any organ? And if that's true, then we should be able to rejuvenate large parts of the body. That's even whole body Rejuvenation at some point. What's exciting about the work is that there are many laps around the world working on this new cause of aging, and learning every week, how to do, resetting the system even better than we are doing now. And so, even if my lab is not the one that successful, they will be a lab around the world that succeeds in resetting, the body and rejuvenating it. So I'm really excited that within a lifetime, we go to see the possibility that aging and be treated like any other medical condition. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/6260092/erythritol-heart-attack-stroke-study/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/6260092/erythritol-heart-attack-stroke-study/"},"headline":"A Sugar Replacement May Be Linked to Heart Attacks and Strokes.
