Abstract:	伴隨著網路普及資訊科技的發展，網路儼然成為最主要的資訊來源管道。在眾多的搜尋需求中，減重相關資訊占了極大的比例，其中飲食扮演相當重要的角色。若參考了品質不佳或不適合自身的資訊並比照執行，可能產生額外的風險。本研究使用DISCERN及PEMAT兩種評估工具對2020年減重飲食相關資訊進行分析，目的為了解各資訊來源的品質及其被理解和執行的難易情形。過程共擷取165個網頁樣本，結果顯示透過網路所獲得的減重飲食相關資訊品質普遍不佳(2.43 ± 0.32/5)，其中又以佔大多數來源(44.8%)的時尚美容類網站評分最低(2.34 ± 0.30)，政府機構及個人專業網站資訊來源品質相對較佳。資訊的可理解度皆有高於建議標準(> 70%)，可執行度則是除了個人專業網站以外皆低於標準(< 70%)，資訊品質、可理解度及可執行度三者皆呈正相關。因此，本研究建議民眾在選擇減重飲食資訊前，應先了解來源平台的可靠性，透過提升品質來強化執行成效，並減少過程中的風險及不可逆的傷害。資訊提供者需更致力於網路資訊品質的控管，塑造一個更理想的網路資訊環境。 Due to the development of technology and the popularity of the Internet, internet has become the main source of information. In numerous searching requirement, information related to weight-loss accounts for a large portion, diet especially. If consumers refer to the poor quality of dieting information and comply with the content, it will be more risk of their health. The purpose of the study aimed to evaluate the quality, understandability and actionability of online dieting information. Content quality was evaluated using DISCERN instruments. Understandability and actionability was evaluated using The Patient Education Materials Assessment Tool (PEMAT). The results indicated the quality of dieting information was mostly poor. The source of information from fashion/beauty websites accounted for the largest proportion had the lowest scores. And the information from personal professional websites had the highest score. Understandability of all sources achieved the adequate criterion. Most sources were under proposed criterion in actionability except personal professional websites. The quality, understandability and actionability of online dieting information shows positive correlation. Therefore, consumer must differentiate the reliability of websites before choosing information to improve the acting effects and avoid the risks. Information providers have to guarantee the quality of information to create a favorable network environment.
