低于推荐的钾摄入量是血压升高的一个公认的风险因素。虽然日本人的饮食与较高的钠摄入量和较低的钾摄入量有关，但很少有研究对来源食物进行定量研究。研究膳食模式与钾摄入量的关系，将有助于提供增加钾摄入量的饮食建议。日本参与者的24小时饮食回忆数据和24小时尿钾排泄数据在国际大量/微量营养素和血压研究（INTERMAP）中，574名男性和571名女性被用来计算钾的食物来源，并比较根据24小时尿钾排泄量/体重（UK/BW）分类的四分位数参与者之间的食物消耗模式。平均钾摄入量为2791毫克/天，主要来源是蔬菜和水果（1262毫克/天），鱼类（333毫克/天），咖啡和茶（206毫克/天），牛奶和乳制品（200毫克/天）。英国/体重四分位数较高的参与者消耗更多的蔬菜和水果，鱼，牛奶和乳制品，吃较少的米饭和面条。结论：建议增加蔬菜和水果，鱼和牛奶的摄入量可能有助于增加日本人的钾摄入量。
A lower-than-recommended potassium intake is a well-established risk factor for increased blood pressure. Although the Japanese diet is associated with higher sodium intake and lower potassium intake, few studies have examined the source foods quantitatively. Studies on dietary patterns in association with potassium intake will be useful to provide dietary advice to increase potassium intake. Twenty-four-hour (hr) dietary recall data and 24-hr urinary potassium excretion data from Japanese participants (574 men and 571 women) in the International Study of Macro/Micronutrients and Blood Pressure (INTERMAP) were used to calculate food sources of potassium and compare food consumption patterns among quartiles of participants categorized according to 24-hr urinary potassium excretion per unit of body weight (UK/BW). The average potassium intake was 2791 mg/day per participant, and the major sources were vegetables and fruits (1262 mg/day), fish (333 mg/day), coffee and tea (206 mg/day), and milk and dairy products (200 mg/day). Participants in the higher UK/BW quartile consumed significantly more vegetables and fruits, fish, and milk and dairy products, and ate less rice and noodles. Conclusion: Advice to increase the intake of vegetables and fruits, fish, and milk may be useful to increase potassium intake in Japan.
