Description
Ruixue Song and colleagues graded in 2026 the dietary advice for cardiovascular disease circulating in short videos on Douyin, the Chinese counterpart of TikTok. Their cross-sectional study, run on a single day in April 2026, kept ninety-eight videos directly about heart-healthy eating. Each video was scored with three established instruments covering overall quality, reliability, and benchmark criteria. The team also recorded who uploaded each video and how audiences engaged with it.
Professionals made most of the content, and fruits and vegetables appeared in nearly every video, while advice to cut oil and salt showed up in under half. Videos from institutions and medical professionals scored significantly higher on every instrument than amateur uploads. Quality correlated only weakly with likes and follower counts, warning viewers that popularity is a poor proxy for sound advice.
