研究结果证明低钠摄入能降低一些高血压患者的血压,因而人们广泛提倡减少钠摄入量。然而,多个随机对照临床试验结果也表明,类似的减少钠摄入量可增加血浆肾素活性、醛固酮分泌、胰岛素抵抗、交感神经活性、血清胆固醇和三酰甘油水平。因此,减少钠摄入量对健康的影响不能仅依赖于其对单一生理特性的作用,而应考虑对各种生理特性作用的综合结果 。 The results show that low sodium intake can lower blood pressure in some hypertensive patients, which led to widespread advocacy to reduce sodium intake. However, several randomized controlled clinical trials have also shown that similar reductions in sodium intake increase plasma renin activity, aldosterone secretion, insulin resistance, sympathetic activity, serum cholesterol, and triglyceride levels. Therefore, reducing the health effects of sodium intake can not depend solely on its effect on a single physiological profile, but on the combined effects of various physiological traits.
