The nutrient intake of persons with diabetes placed on a low-carbohydrate diet remains unclear. This study aimed to assess nutrient intake in persons with type 2 diabetes mellitus treated with a low-carbohydrate diet. The brief-type self-administered diet history questionnaire was used to collect the dietary information of 335 outpatients at Kitasato Institute Hospital, while their clinical characteristics were collected from their electronic medical records. The median age, HbA1c level, and body mass index of the participants were 68 (60-74) years, 49 (45-55) mmol/mol [6.7 (6.3-7.2)%], and 24.0 (21.8-26.7) kg/m, respectively; median energy intake was 1457 (1153-1786) kcal/day; and protein-energy, fat-energy, and available carbohydrate-energy ratios were 18.6 (15.7-21.4)%E, 36.8 (31.6-43.2)%E, and 34.6 (26.0-42.4)%E, respectively. As the available carbohydrate-energy ratio decreased, the fat-energy ratio increased significantly. The total dietary fibre and salt intake were 7.1 (5.6-8.4) g/1000 kcal and 6.5 (5.6-7.5) g/1000 kcal, respectively. Japanese individuals with type 2 diabetes mellitus placed on a low-carbohydrate diet had a fat-to-energy ratio exceeding 30%, while the fat-energy ratio increased as the carbohydrate-energy ratio decreased.
低碳水化合物饮食患者的营养素摄入量仍不清楚。本研究旨在评估接受低碳水化合物饮食治疗的 2 型糖尿病患者的营养素摄入量。使用简短型自我管理饮食历史问卷收集了来自 Kita-sato 研究所医院的 335 名门诊患者的饮食信息，同时从他们的电子病历中收集了他们的临床特征。参与者的中位年龄、HbA1c 水平和体重指数分别为 68（60-74）岁、49（45-55）mmol/mol [6.7（6.3-7.2）%]和 24.0（21.8-26.7）kg/m2；中位能量摄入量为 1457（1153-1786）kcal/天；蛋白质能量比、脂肪能量比和可利用碳水化合物能量比分别为 18.6（15.7-21.4）%E、36.8（31.6-43.2）%E和 34.6（26.0-42.4）%E。随着可利用碳水化合物能量比的降低，脂肪能量比显著增加。膳食纤维和盐的总摄入量分别为 7.1（5.6-8.4）g/1000kcal 和 6.5（5.6-7.5）g/1000kcal。接受低碳水化合物饮食的日本 2 型糖尿病患者的脂肪能量比超过 30%，而随着碳水化合物能量比的降低，脂肪能量比增加。
