Having an incurable illness raises a number of special nutritional issues for both the patient and the health professional. This review covers two of these issues: the use of unproven dietary products to improve immune function, and the role of nutritional support in palliative care. The usage of unproven dietary strategies, particularly vitamin and mineral supplements, is extremely popular in patients with incurable diseases such as HIV infection. A daily multivitamin and mineral supplement plus an additional supplement of beta-carotene may be beneficial in terms of slowing progression to AIDS, but megadosing of vitamins, minerals and Chinese herbs, and the use of 'special diets' should be cautioned against. The two main areas where nutritional support appears to be important in palliative care are symptom control and aggressive feeding as a means of stabilising body weight. The psychological benefits of appropriate nutritional advice and support are highlighted.
身患不治之症会给患者和医护人员带来一系列特殊的营养问题。本综述涵盖其中两个问题：使用未经证实的膳食产品来改善免疫功能，以及营养支持在姑息治疗中的作用。未经证实的膳食策略，尤其是维生素和矿物质补充剂的使用，在诸如艾滋病毒感染等不治之症患者中极为普遍。每日服用多种维生素和矿物质补充剂外加额外补充β-胡萝卜素可能有助于减缓艾滋病的进展，但应警惕大剂量服用维生素、矿物质和中草药以及使用“特殊饮食”。营养支持在姑息治疗中似乎重要的两个主要方面是症状控制以及通过积极喂食来稳定体重。适当的营养建议和支持所带来的心理益处也得到了强调。
