The purpose of this study was to identify dietary patterns among patients with advanced cancer. Differences between cancer groups are described, and food groups contributing higher proportions to overall caloric intake are identified. Patients with advanced cancer (n=51) were recruited from a regional cancer centre and completed a three-day dietary record. Food items were categorized according to macronutrient content. After adjustment for body weight, substantial variation in energy intake was observed (range: 13.7 to 55.4 kcal/kg/day). For 49% of patients, protein intake was below recommendations. Overall, patients consumed the largest proportion of their calories from meat (16%), other foods (11%), dessert (9%), fruit (9%), white bread (7%), and milk (7%). Only 5% of patients consumed meal replacement supplements. The results of this descriptive study provide important insights into the dietary habits of patients with advanced cancer. These insights could be translated into the development of effective recommendations for maintaining or improving health and quality of life.
本研究的目的是确定晚期癌症患者的饮食模式。描述了癌症组之间的差异，并确定了在总热量摄入中占较高比例的食物组。从一个地区癌症中心招募了51名晚期癌症患者，并让他们完成一份为期三天的饮食记录。食物项目根据宏量营养素含量进行分类。在对体重进行调整后，观察到能量摄入存在很大差异（范围：13.7至55.4千卡/千克/天）。49%的患者蛋白质摄入量低于推荐量。总体而言，患者摄入热量的最大比例来自肉类（16%）、其他食物（11%）、甜点（9%）、水果（9%）、白面包（7%）和牛奶（7%）。只有5%的患者食用代餐补充剂。这项描述性研究的结果为晚期癌症患者的饮食习惯提供了重要见解。这些见解可以转化为制定有效的建议，以维持或改善健康和生活质量。
