介绍：报纸报道提倡饮食摄入量的变化可能会影响饮食选择和食物相关的健康信念。这些报告的科学依据和证据质量尚不确定。目的：评价报纸膳食建议报道的科学性。设计图：随机选择一周，从英国十大畅销报纸上提供饮食建议的文章，使用两个既定的证据分级量表进行评估：由世界癌症研究基金会（WCRF）和苏格兰校际指南网络（SIGN）开发。结果如下：在确定的111种膳食健康声称中，72%和68%（分别按WCRF和SIGN标准评估）的证据水平低于推荐的膳食健康声称的令人信服或可能类别。结论：英国报纸对饮食建议的误报很普遍，可能导致公众对食品和健康的误解。
Introduction: Newspaper reports advocating dietary intake changes may impact on dietary choice and food related health beliefs. The scientific basis and quality of evidence underpinning these reports is uncertain. Objective: To evaluate the scientific quality of newspaper reporting related to dietary advice. Design: Articles offering dietary advice from the top ten selling UK newspapers for a randomly selected week were assessed using two established evidence grading scales: developed by the World Cancer Research Fund (WCRF) and the Scottish Intercollegiate Guidelines Network (SIGN). Results: Of 111 dietary health claims identified, 72% and 68% (assessed by WCRF and SIGN criteria respectively) had levels of evidence lower than the convincing or probable categories that are recommended for dietary health claims. Conclusions: Misreporting of dietary advice by UK newspapers is widespread and may contribute to public misconceptions about food and health.
