A variety of materials offering healthy eating advice have been produced in the United Kingdom to encourage people to eat well and avoid diet-related health issues. By applying a Foucauldian discourse analysis, this research aimed to uncover the discourses used in six healthy eating texts (two state-produced and four commercial texts), how people positioned themselves in relation to these discourses, and the power relations between institutions and the U.K. public. Ten discourses including scientific, thermodynamics, natural, family/caring, emotional, medical, and moral discourses were uncovered and offered up subject positions in relation to moral citizenship and personal responsibility. Through the use of biopower, foods appeared to be categorized as “good” or “bad” foods in which bad foods were considered to be risky to health due to their nutritional composition. Most texts assumed people have the agency to follow the advice provided and failed to consider the readers’ personal contexts.

英国制作了各种提供健康饮食建议的材料，以鼓励人们吃得好，避免与饮食有关的健康问题。通过应用福柯式话语分析，本研究旨在揭示六种健康饮食文本（两份国产文本和四份商业文本）中使用的话语、人们如何在这些话语中定位自己，以及机构与英国之间的权力关系民众。包括科学、热力学、自然、家庭/关怀、情感、医学和道德话语在内的十个话语被发现，并提供了与道德公民和个人责任相关的主题职位。通过使用生物能源，食物似乎被归类为“好”或“坏”食物，其中坏食物因其营养成分而被认为对健康有害。大多数文本假设人们有能力遵循所提供的建议，而没有考虑读者的个人背景。
