美国科学家Kaplan研究表明高血压病人补钾,不仅能改善利尿剂招致的低血钾,且能降低血压。一些研究者指出高钾饮食具有抵抗高血压的效果,特别是在传统饮食高盐的日本显得更重要。有一个试验组研究表明血压与血钾排泄物呈反比,而与尿中的Na~+/K~+呈正比。另据报道,日本北部的两个乡村,盐摄入量相似,但血压却不相同,摄入高钾的乡村血压较低。对正常血压和高血压美国人混合组的 Kaplan study of American scientists showed that potassium in patients with hypertension, not only can improve diuretic-induced hypokalemia, and can lower blood pressure. Some researchers have pointed out that high-potassium diet has the effect of resisting hypertension, especially in Japan, where traditional diet and high salt are more important. A pilot study showed that blood pressure and serum potassium excretion was inversely proportional to urinary Na ~ + / K ~ + is proportional. It was also reported that salt intake was similar in two villages in northern Japan, but blood pressure was not the same, with lower blood pressure in villages with high potassium intake. For normal blood pressure and hypertension in the American mixed group
