BACKGROUND/OBJECTIVES: Dietary pattern is central in the prevention of hypertension and blood pressure (BP)-related diseases. A diet based on healthy Nordic foods may have a favourable impact on BP. The objective was to clarify whether a Nordic alternative for a healthy food pattern would have beneficial effects on ambulatory BP in subjects with metabolic syndrome (MetS).
SUBJECTS/METHODS: In total, 37 subjects were randomized to either a healthy Nordic diet or a control diet. A healthy Nordic diet embraced whole grains, rapeseed oil, berries, fruits, vegetables, fish, nuts and low-fat dairy products of Nordic origin. The mean nutrient intake in the Nordic countries formed the control diet, embracing wheat products, dairy fat-based spread and a lower intake of fruits, vegetables and fish. Diets were isoenergetic. Ambulatory BP was monitored and 24-h urine was collected before and after 12 weeks of intervention.
After 12 weeks, ambulatory diastolic BP (-4.4 mm Hg; P=0.001) and mean arterial pressure (-4.2 mm Hg; P=0.006) were lowered by the healthy Nordic diet compared with the control diet, whereas changes in ambulatory systolic BP did not differ significantly between diets (-3.5 mm Hg; P=0.122). Heart rate tended to be lower in those on the healthy Nordic diet (P=0.057). Urinary sodium and potassium excretions were unaffected by diets and consequently not associated with the healthy Nordic diet-induced lowering of BP.
Consumption of Nordic varieties of health-enhancing foods for 12 weeks decreased diastolic ambulatory BP and mean arterial pressure in subjects with features of MetS during weight-stable condition, suggesting beneficial effects of a healthy Nordic dietary pattern on ambulatory BP.
背景/目的：饮食模式是预防高血压和与血压相关疾病的核心。基于健康北欧食品的饮食可能对血压有有利影响。本研究旨在阐明代谢综合征（MetS）患者的健康北欧饮食替代方案是否对动态血压有有益影响。
受试者/方法：共有 37 名受试者被随机分配到健康的北欧饮食或对照饮食组。健康的北欧饮食包括全谷物、菜籽油、浆果、水果、蔬菜、鱼类、坚果和低脂乳制品。北欧国家的平均营养素摄入量构成了对照饮食，包括小麦制品、基于乳脂的涂抹酱以及水果、蔬菜和鱼类的摄入量较低。两种饮食均为等热量饮食。在干预 12 周前后监测动态血压并收集 24 小时尿液。
12 周后，与对照饮食相比，健康的北欧饮食使动态舒张压（-4.4mmHg；P=0.001）和平均动脉压（-4.2mmHg；P=0.006）降低，而动态收缩压的变化在两种饮食之间无显著差异（-3.5mmHg；P=0.122）。健康的北欧饮食组的心率较低（P=0.057）。饮食对尿钠和钾排泄没有影响，因此与健康的北欧饮食诱导的血压降低无关。
在体重稳定的情况下，摄入富含健康北欧食品的饮食 12 周可降低 MetS 特征患者的舒张压和平均动脉压，表明健康的北欧饮食模式对动态血压有益。
