- A new Nature Medicine paper (doi:10.1038/s41591-023-02223-9) and accompanying media coverage claim that the common low-calorie sweetener xylitol is linked to increased risk of heart attack and stroke, prompting discussion of its plausibility and mechanism of action.

- The underlying European Heart Journal study (doi:10.1093/eurheartj/ehae244) reports that xylitol exhibits pro-thrombotic effects in both in-vitro and in-vivo experiments and shows a strong, continent-spanning epidemiological correlation, with the highest quartile of blood xylitol levels showing markedly higher cardiovascular risk.

- Channel participants debate whether polyol sweeteners like xylitol are a meaningful concern for people whose vascular or renal systems are already compromised, versus being a minor factor compared to broader metabolic dysfunction.

- A question is raised about why the fourth (highest) quartile of xylitol exposure shows a disproportionate jump in risk compared to the lower quartiles, suggesting a possible threshold or non-linear dose-response relationship.
