BACKGROUND Type 2 diabetes mellitus is a metabolic disorder characterized by high glucose and insulin resistance. It is strongly linked to lifestyle, including poor diet and physical inactivity. Lupin is a novel food ingredient, rich in protein and fibre with negligible sugar and starch, which can be incorporated into various foods to reduce glycaemic load. Regular consumption of lupin-enriched foods may be a novel and easily achievable means of reducing overall glycaemic load and improving glycaemic control in diabetes. OBJECTIVE To determine whether regular consumption of lupin-enriched foods can improve glycaemic control and lower blood pressure in people with type 2 diabetes mellitus. DESIGN Fourteen men and 8 women (mean age 58.0 ± 6.6 years and BMI 29.0 ± 3.5 kg m-2) with type 2 diabetes mellitus were recruited from the general population to take part in a double-blind, randomised, controlled cross-over study. Participants consumed lupin or control foods for breakfast and lunch every day, and for dinner at least 3 days per week during the 8-week treatment periods. Lupin-enriched foods consisted of bread, pasta, Weetbix™ cereal and crumbs, with energy-matched control products. Treatments were completed in random order with an 8-week washout period. All participants monitored their blood glucose levels pre- and post-breakfast and lunch, and their blood pressure in the morning and evening, 3 days per week for the duration of each treatment period. RESULTS Seventeen participants completed both treatment arms, with all 22 participants (14 males, 8 females) analysed on an intention-to-treat basis. Eight weeks consumption of lupin-enriched food had no significant effect on mean blood glucose levels (mean difference: -0.08 ± 0.06 mmol L-1, p = 0.214) or post-prandial blood glucose levels (-0.13 ± 0.10 mmol L-1, p = 0.196). There was no effect on home systolic (-0.4 ± 0.4 mmHg, p = 0.33) or diastolic (0.3 ± 0.3 mmHg, p = 0.321) blood pressure and heart rate (0.5 ± 0.3 bpm, p = 0.152), and no effect on body weight throughout the treatment periods. CONCLUSION Regular consumption of lupin-enriched foods had no significant effect on glycaemic control or blood pressure in people with type 2 diabetes mellitus.

经常食用含羽扇豆的食物对2型糖尿病患者的血糖控制和血压的影响。

背景技术2型糖尿病是一种以高葡萄糖和胰岛素抵抗为特征的代谢疾病。它与生活方式密切相关,包括不良饮食和缺乏运动。羽扇豆是一种新型的食品成分,富含蛋白质和纤维,而糖和淀粉的含量可以忽略不计,可以将其掺入各种食品中以降低血糖负荷。经常食用富含羽扇豆的食物可能是减少糖尿病患者总体血糖负荷和改善血糖控制的一种新颖且容易实现的方法。目的确定经常食用富含羽扇豆的食物是否可以改善2型糖尿病患者的血糖控制和降低血压。设计14名男性和8名女性(平均年龄58.0±6.6岁,BMI 29.0±3。从普通人群中招募了5公斤m-2)的2型糖尿病患者,参加了一项双盲,随机,对照交叉研究。在8周的治疗期间,参与者每天早餐和午餐以及每周至少3天的晚餐都食用羽扇豆或控制食物。富含羽扇豆的食物包括面包,意大利面,Weetbix™谷物和面包屑以及能量匹配的控制产品。治疗以随机顺序完成,洗脱期为8周。所有参与者在早餐前后,午餐和午餐前后监测血糖水平,并在每个治疗期间每周3天在早晨和傍晚监测血压。结果17名参与者完成了两个治疗臂的治疗,所有22名参与者(14名男性,8名女性)均按意向性治疗进行了分析。食用富含羽扇豆的食物八周对平均血糖水平(均差:-0.08±0.06 mmol L-1,p = 0.214)或餐后血糖水平(-0.13±0.10 mmol L-1)没有显着影响,p = 0.196)。对家庭收缩压(-0.4±0.4 mmHg,p = 0.33)或舒张压(0.3±0.3 mmHg,p = 0.321)血压和心率(0.5±0.3 bpm,p = 0.152)没有影响,对在整个治疗期间的体重。结论经常食用富含羽扇豆的食物对2型糖尿病患者的血糖控制或血压没有显着影响。对家庭收缩压(-0.4±0.4 mmHg,p = 0.33)或舒张压(0.3±0.3 mmHg,p = 0.321)血压和心率(0.5±0.3 bpm,p = 0.152)没有影响,对在整个治疗期间的体重。结论经常食用富含羽扇豆的食物对2型糖尿病患者的血糖控制或血压没有显着影响。对家庭收缩压(-0.4±0.4 mmHg,p = 0.33)或舒张压(0.3±0.3 mmHg,p = 0.321)血压和心率(0.5±0.3 bpm,p = 0.152)没有影响,对在整个治疗期间的体重。结论经常食用富含羽扇豆的食物对2型糖尿病患者的血糖控制或血压没有显着影响。
