                                In 2023, a study published in *Nature Medicine* revealed a significant finding: higher circulating levels of the sugar alcohol erythritol were associated with an elevated risk of heart attack and stroke. This discovery has sparked new concerns about popular sugar substitute erythritol, a low-calorie sweetener widely used in 'keto' and 'sugar-free' products.
