Your favorite sugar-free treats could also be harming your heart health. Higher amounts of the low-calorie sweetener xylitol, often marketed as a healthy sugar substitute, are linked to an increased risk of cardiovascular events resembling stroke and heart attack, in line with a brand new study from the Cleveland Clinic.
A team of researchers, including Dr. Stanley HazenChair by Cardiovascular and metabolic sciences At the Cleveland Clinic Lerner Research Institutefound a link between high blood xylitol concentrations and an increased three-year risk of cardiovascular events in an evaluation of greater than 3,300 patients. The results were published last week within the European Heart Journal.
“People whose xylitol levels were in the top 25% of our population – the top quartile – had twice the risk of heart attack, stroke and death as people whose levels were in the bottom quartile,” says Hazen. Assets“Our data are fully consistent with the idea that xylitol is a prothrombotic compound (prone to blood clot formation) and increases cardiovascular risk – exactly the compound we often recommend to patients as a sugar substitute, especially if they are diabetic.”
In one other a part of the study, subjects were asked to drink water sweetened with xylitol. The amount of xylitol in each drink was comparable to that in a serving of keto ice cream or diabetic cookies, says Hazen. The researchers then tested the themes’ blood Platelets or thrombocytesthe cell fragments that form clots.
“After drinking this typical dose, blood levels increased more than 1,000-fold to superphysiological levels,” says Hazen. “In every subject studied, they remained in this high range – which is associated with a higher risk of cardiovascular disease – for the next four to six hours, and every platelet function level we examined was significantly elevated.”
This discovery got here just over a 12 months after Hazen and his colleagues found the same relationship between the synthetic sweetener Erythritol and cardiovascular event riskIn the U.S., xylitol isn’t as common as erythritol in ketogenic or sugar-free foods, in line with a study from the Cleveland Clinic. Press releaseHowever, in other countries it’s present in large quantities.
What is xylitol?
Xylitol is typically known as Sugar Alcoholso called because parts of its chemical structure are much like those of sugar and alcohol. Sugar alcohols, also called polyols, are carbohydrates that occur naturally in some vegatables and fruits. They don’t contain Ethanolthe kind of alcohol in alcoholic beverages.
Sugar alcohols are popular sugar substitutes because they taste sweet but have fewer calories per gram than sugar, in line with the Food and Drug Administration (FDA). They are often used together with artificial sweeteners and might be produced commercially from sugar and starch.
Sugar alcohols prevent browning, help retain moisture and add bulk and structure, in line with the FDA, making them a really perfect ingredient in processed foods like baked goods. Your body cannot fully absorb sugar alcohols, so consuming them won’t spike your blood sugar levels like regular sugar does.
The cooling feeling in your mouth after brushing your teeth? That is a sign of a high sugar alcohol content. Since sugar alcohols don’t cause tooth decay, they are sometimes utilized in oral care products. Xylitol is especially often utilized in chewing gum.
As demand for low-sugar, low-calorie foods increases, the sugar alcohol market continues to boom and is anticipated to exceed $1.8 billion by 2033. Persistence Market Research. Xylitol, also called birch or wood sugar, has low production costs, which is one other advantage for the industry, says Hazen.
“[Xylitol] is literally made from wood pulp and sawdust. It is cheaper to make xylitol than to isolate cane sugar from sugar cane,” says Hazen Assets“And it tastes just like sugar – just as sweet, it’s grainy – so it has a lot of benefits.”
These aspects are also what make xylitol so dangerous, he says.
Which foods contain xylitol?
According to the FDA, the sugar substitute is present in quite a few foods and other products, including:
- Peppermint candies
- Bakery products
- Cough Syrup
- Mouthwash
- toothpaste
- some peanut and nut butter
- Dietary supplements
- sugar-free desserts

Is the usage of sugar substitutes protected?
Last 12 months World Health Organization advised against the usage of sugar-free sweeteners, especially as a way of weight control. As sugar derivatives containing calories, sugar alcohols were exempted from the authority’s recent directive. Nevertheless, the decree marked a change in consumer attitudes towards sugar and its substitutes.
The non-profit food inspection authority Centre for Science within the Public Interest recommends reducing xylitol consumption, as large amounts can result in diarrhea. (In humans, xylitol is deadly for dogs.) Hazen would like if you happen to would stop altogether.
“If [you] If you want to sweeten something, I think it’s better to use sugar, honey or fruit at this point, and in moderation,” he says. “If you’re diabetic, monitor your blood sugar.”
Consult your doctor and/or nutritionist before making any drastic changes to your food plan.
Given the complexity of heart problems and the restrictions of Hazen’s research, it might be far-fetched to conclude that xylitol causes Events resembling stroke and heart attack, he says. More long-term studies are needed. For example, it’s unclear whether adolescents who continuously devour sugar substitutes develop a better risk of a cardiovascular event than their peers who don’t.
Hazen is now so concerned in regards to the health risks of xylitol that he’s pushing for a revision of the dietary labeling.
“It’s a big public health problem,” he says. “We really need to lobby and get regulatory changes so that it’s no longer widely considered safe.”
