钠对于细胞内稳态和生理功能是必不可少的。过量的饮食钠与血压升高有关。BP的盐敏感性差异很大,但某些亚组倾向于更盐敏感。钠诱导的血压升高的潜在机制尚未完全了解,但可能涉及肾功能、液体容量、液体调节激素、血管系统、心脏功能和自主神经系统的改变。最近的临床前和临床数据支持,即使在没有血压升高的情况下,过量的膳食钠也会对靶器官产生不利影响,包括血管、心脏、肾脏和大脑。在这篇综述中,我们讨论了这些问题和流行病学文献有关的饮食钠BP和心血管健康的结果,解决最近的争议。我们还提供减少膳食钠的信息和策略。
Sodium is essential for cellular homeostasis and physiological function. Excess dietary sodium has been linked to elevations in blood pressure (BP). Salt-sensitivity of BP varies widely, but certain subgroups tend to be more salt-sensitive. The mechanisms underlying sodium-induced increases in BP are not completely understood, but may involve alterations in renal function, fluid volume, fluid regulatory hormones, the vasculature, cardiac function, and the autonomic nervous system. Recent pre-clinical and clinical data support that even in the absence of an increase in BP, excess dietary sodium can adversely affect target organs, including the blood vessels, heart, kidneys, and brain. In this review, we address these issues and the epidemiological literature relating dietary sodium to BP and cardiovascular health outcomes, addressing recent controversies. We also provide information and strategies for reducing dietary sodium.
