A total of 98 videos directly related to CVD dietary guidance were included after screening. Baseline characteristics, uploader types, and user engagement metrics were extracted.

Fruits and vegetables (98.0%) and grains and tubers (87.0%) were the most frequently covered dietary categories, whereas oil and salt restriction was less frequently addressed (47.0%). Videos uploaded by professional institutions and medical professionals achieved higher GQS, mDISCERN, and JAMA scores than those from nonprofessional creators (all\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001).
