H ypertension is the most common chronic disease worldwide, affecting 1 billion individuals and contributing to 1 in 8 deaths per year (1). It causes substantial morbidity and mortality, as a major risk factor for heart failure, stroke, coronary artery disease, renal dysfunction, and blindness. The prevalence of hypertension is increasing and uncontrolled hypertension remains a common problem (2,3). Therefore, effective, widely available, low-cost, and sustainable strategies are needed to prevent and treat hypertension. Lifestyle modification, including diet, is a cornerstone for the prevention and treatment of hypertension (4). Reducing dietary sodium below that of typical diets eaten around the world lowers blood pressure (5). The DASH (Dietary Approaches to Stopping Hypertension) diet, comprised of fruits, vegetables, low-fat dairy products, and foods low in saturated fat and cholesterol, has also been shown to reduce blood pressure (6). In the DASH-sodium randomized crossover trial, combining the DASH diet with low sodium was additive for lowering blood pressure (7).

高血压是全世界最常见的慢性病，​​影响着 10 亿人，每年有八分之一的人死于高血压 (1)。它会导致大量的发病率和死亡率，是心力衰竭、中风、冠状动脉疾病、肾功能障碍和失明的主要危险因素。高血压的患病率正在增加，不受控制的高血压仍然是一个常见问题 (2,3)。因此，需要有效、广泛可用、低成本和可持续的策略来预防和治疗高血压。生活方式的改变，包括饮食，是预防和治疗高血压的基石 (4)。将饮食中的钠含量降低到低于世界各地典型饮食的水平可以降低血压 (5)。DASH（停止高血压的饮食方法）饮食，包括水果、蔬菜、低脂乳制品、以及饱和脂肪和胆固醇含量低的食物，也已被证明可以降低血压 (6)。在 DASH-钠随机交叉试验中，将 DASH 饮食与低钠相结合是降低血压的添加剂 (7)。
