本文分析了膳食蛋白质摄入的质与量,空腹血清及八小时夜尿中游离氨基酸含量与血压的关系。结果表明,膳食动物蛋白质/总蛋白质,蛋白质/钠摄入量的比值,血清及尿牛磺酸,赖氨酸等和血压呈显著负相关;丙氨酸等和血压显著正相关;血清氨基酸和膳食蛋白质/钠比值显著正相关;尿牛磺酸,赖氨酸,门冬酰胺等和蛋白质摄入量,钠摄入量及排泄量显著正相关。提示富含牛磺酸,赖氨酸等的优质蛋白质可能预防高血压。 This article analyzes the quality and quantity of dietary protein intake, fasting serum and eight-hour nocturnal urine free amino acid content and blood pressure. The results showed that dietary protein / total protein, protein / sodium intake ratio, serum and urine taurine, lysine and blood pressure was significantly negatively correlated; alanine and blood pressure was significantly positively correlated; serum amino acids and Dietary protein / sodium ratio was significantly and positively correlated; urine taurine, lysine, asparagine and other protein intake, sodium intake and excretion were significantly positively correlated. Tip Rich in taurine, lysine and other high-quality protein may prevent high blood pressure.
