To understand the extent to which different sources of diet and nutrition information are sought, trusted, and relied upon for making dietary changes, the present international web-based survey study gauged participants' ( = 3419) diet-nutrition information-seeking behaviors from 22 interpersonal and general sources with varying quality, trust levels in these sources, and reliance on each source for making dietary changes. Qualitative insights were also captured regarding trustworthiness formation. The results revealed a disconnect between source popularity and perceived trustworthiness. While nutrition-health websites, Google-Internet searches, and diet-health books were most commonly consulted, participants placed the highest level of trust in nutrition scientists, nutrition professionals, and scientific journals, suggesting that frequent information seeking from a subpar source may not be a reliable predictor of the level of trust assigned to it. Although the frequency of source-seeking behaviors and source trustworthiness both contributed to dietary changes, the latter appeared to have a more pronounced influence. When a source was less trusted, there was a reduced likelihood of relying on it for changing diet. Additionally, source seeking may not always translate into effective dietary change, as shown by the less strong correlation between the two. These associations significantly differed depending on the source.
为了了解人们在多大程度上寻求、信任和依赖不同来源的饮食和营养信息来改变饮食，本项国际网络调查研究从 22 个人际和一般来源衡量了参与者（=3419 人）的饮食-营养信息搜索行为，这些来源的质量、对这些来源的信任程度以及对每种来源改变饮食的依赖程度各不相同。研究还获取了有关信任度形成的定性见解。研究结果显示，来源受欢迎程度和感知可信度之间存在脱节。尽管营养健康网站、谷歌互联网搜索和饮食健康书籍是最常被咨询的来源，但参与者对营养科学家、营养专业人员和科学期刊的信任度最高，这表明从一个质量较差的来源频繁搜索信息，可能并不能可靠地预测对其的信任程度。尽管信息源搜索行为的频率和信息源的可信度都对饮食变化有影响，但后者的影响似乎更为显著。当一个来源的可信度较低时，人们就不太可能依赖它来改变饮食。此外，信息源搜索并不总是能转化为有效的饮食改变，这一点从两者之间的相关性较弱就可以看出。这些关联因来源而异。
