Cleveland, Ohio – A recent study led by the Cleveland Clinic published in the European Heart Journal has raised concerns about the potential health risks associated with the consumption of the low-calorie sweetener xylitol. The study found a link between elevated levels of xylitol in the blood and an increased risk of heart attack, stroke, or cardiovascular-related deaths over a three-year period among more than 3,000 participants.
Experts like Grace A. Derocha, M.B.A., R.D., C.D.C.E.S., Adedapo Iluyomade, M.D., and Jackie Newgent, R.D.N., C.D.N., have highlighted the importance of understanding the impact of xylitol on heart health. Xylitol, a sugar alcohol commonly used as a sweetener in gums, candies, and oral care products, has about the same sweetness as table sugar but with fewer calories. It is often used by individuals looking to manage their carbohydrate intake or blood glucose levels, such as those with type 2 diabetes or obesity.
In addition to its role as a sugar substitute, xylitol has been lauded for its potential benefits in improving dental health. It can help reduce the growth of harmful bacteria in the mouth, lower the risk of cavities and tooth decay, and promote saliva production, which aids in neutralizing acids and repairing tooth enamel.
While xylitol may offer certain advantages, such as a low glycemic index and dental health benefits, it is essential for pet owners to be cautious as xylitol is highly toxic to dogs. Even small amounts of xylitol ingested by dogs can lead to severe health issues, including hypoglycemia and liver failure.
Although consuming xylitol is generally considered safe for humans, it can have some side effects when consumed in large quantities, such as gastrointestinal issues, a laxative effect, allergic reactions, and potential interference with nutrient absorption. Individuals with irritable bowel syndrome or other gastrointestinal sensitivities may experience more pronounced side effects.
In light of the recent study linking xylitol to an increased risk of heart attack and stroke, experts emphasize the importance of moderation and conducting further research on the potential health implications of xylitol consumption. Patients are advised to consult their healthcare providers before making any dietary changes involving xylitol, especially those with or at risk for cardiovascular disease.
