The Claim

Higher sucralose intake is associated with a 31% increased risk of coronary heart disease, with an absolute incidence rate of 271 cases per 100,000 person-years among higher consumers compared to 161 cases per 100,000 person-years among non-consumers, based on data from 103,388 French adults followed for a median of 9 years.

In plain English

Drinking or eating a lot of sucralose might be linked to a higher chance of heart problems — like 31% higher — based on a big study of French adults who were followed for about 9 years.
