Scientific evidence is necessary for the development of effective and enforceable regulations and government policy. To use scientific information appropriately, a systematic approach is needed for review and evaluation of the evidence. Federal agencies in the United States have developed useful approaches for such a review and evaluation to develop nutrition labeling, including health claims, and for updating of the Dietary Guidelines for Americans. The WHO is using a systematic evaluation process to update its recommendations on diet and health. The results of such reviews also highlight research needs to address relevant gaps in our knowledge.
科学证据对于制定有效且可执行的法规和政府政策至关重要。为了恰当地使用科学信息,需要一种系统的方法来审查和评估证据。美国的联邦机构已经开发出了用于此类审查和评估的有用方法,以制定营养标签,包括健康声明,并更新《美国人膳食指南》。世界卫生组织正在使用系统的评估过程来更新其关于饮食与健康的建议。此类审查的结果还突出了为填补我们知识中的相关空白而开展研究的必要性。
