Sugar Substitute Xylitol Tied to Higher Risk of Heart Attack, Stroke, and Death, Study Finds

A new peer‑reviewed study links Xylitol consumption to a 57% higher risk of major heart attack or stroke, according to The Sun. Xylitol is widely used in sugar‑free gum, dental products and diet foods, where it has been praised for reducing cavities. Pharmaceutical Technology reported that the link emerged from data presented at the European Society of Cardiology 2026 meeting, while U.S.

News & World Report called the finding a higher heart risk for the popular sweetener. Gizmodo echoed the headline, noting the study ties Xylitol to increased mortality alongside heart attack and stroke. The coverage stresses concern for regular consumers of Xylitol‑containing gum, toothpaste and diabetic‑friendly foods, balancing dental benefits against cardiovascular warnings.

What to watch next includes monitoring statements from health regulators such as the FDA and European Food Safety Authority, and tracking any follow‑up clinical trials announced by research institutions. The study’s prominence suggests possible revisions to dietary guidelines and product labeling, though official actions remain unreported at this stage.
