To review the possibilities of using the Internet and especially the World Wide Web (WWW) in nutrition education.
A healthy existence is partly dependent on dietary behaviours. One way to promote health-promoting dietary habits is nutrition education. In the last decades several potentially important new channels for health communication and nutrition education have emerged, with the Internet and its WWW as the most striking example. The introduction and growth of the WWW has enabled swift and inexpensive distribution of nutrition education expertise and materials. Furthermore, the WWW has also been used for tailoring nutrition education to the personal characteristics of the user. Only few studies have investigated the effects of generic web-based nutrition education, while web-based computer-tailored nutrition education has been studied in randomised controlled trials, with promising but mixed results. Two important challenges for web-based nutrition education interventions are to realise sufficient exposure and to ensure sufficient source reliability and credibility.
Next to the great opportunities, there are many challenges for web-based nutrition education. Some evidence for effects of web-based computer-tailored nutrition education has been reported, but more research is needed to obtain evidence for the effectiveness in real-life situations.
回顾利用互联网尤其是万维网（WWW）进行营养教育的可能性。
健康的生活方式部分取决于饮食行为。促进健康饮食习惯的一种方法是营养教育。在过去几十年中，出现了几个潜在的重要健康传播和营养教育新渠道，其中互联网及其万维网最为突出。万维网的引入和发展使得营养教育专业知识和材料能够迅速且低成本地传播。此外，万维网还被用于根据用户的个人特点定制营养教育。只有少数研究调查了通用的基于网络的营养教育的效果，而基于网络的计算机定制营养教育已在随机对照试验中进行研究，结果有希望但参差不齐。基于网络的营养教育干预面临的两个重要挑战是实现足够的曝光度以及确保足够的来源可靠性和可信度。
除了巨大的机遇外，基于网络的营养教育也面临许多挑战。已报道了一些基于网络的计算机定制营养教育效果的证据，但需要更多研究来获取其在现实生活中有效性的证据。
