鹽，吃多了不行，少了也不好

The human body needs a tiny amount of sodium to function properly and this is typically found in salt (sodium chloride).

人體需要少量的鈉才能正常運轉(zhuǎn)，這通常存在于鹽(氯化鈉)中。

But today most people consume way too much salt, increasing the burden of cardiovascular disease around the world.

但今天，大多數(shù)人攝入了太多的鹽，增加了世界各地心血管疾病的負擔。

Health professionals have been trying to tackle this problem for decades, but face several barriers, including research that muddies the water about what safe levels of salt intake are.

幾十年來，健康專業(yè)人士一直在努力解決這個問題，但也面臨著一些障礙，包括關(guān)于鹽攝入量安全水平的研究。

This has cast unnecessary doubt on the importance of reducing intakes.

這使人們對減少攝入量的重要性產(chǎn)生了不必要的懷疑。

But our latest research has found flaws in these studies and suggests that salt intake should be reduced even further than current recommendations.

但我們最新的研究發(fā)現(xiàn)這些研究存在缺陷，并建議減少鹽的攝入量，甚至應(yīng)該比目前的建議更少。

The World Health Organisation (WHO) recommends that people consume less than 5 grams of salt a day, but global intakes average 10 grams a day.

世界衛(wèi)生組織(WHO)建議人們每天攝入的鹽少于5克，但全球平均每天攝入10克。

Excess salt consumption raises blood pressure, which increases the risk of heart attacks, heart failure and stroke.

過量食用鹽會導(dǎo)致血壓升高，從而增加心臟病發(fā)作、心力衰竭和中風(fēng)的風(fēng)險。

They posit that consuming both less than 7.5 grams and more than 12.5 grams of salt per day could lead to an increased risk of cardiovascular disease and early death.

他們假設(shè)每天攝入少于7.5克和多于12.5克的鹽都會增加心血管疾病和早死的風(fēng)險。

A gradual reduction in salt intake across the whole population, as recommended by WHO, remains an achievable, affordable, effective and important strategy to prevent cardiovascular diseases and premature death worldwide.

按照世衛(wèi)組織的建議，在全體人口中逐步減少鹽的攝入量仍然是一項可實現(xiàn)的、負擔得起的、有效的和重要的戰(zhàn)略，可在全世界預(yù)防心血管疾病和過早死亡。

Even a small reduction in salt intake will have an enormous benefit on people's health.

即使是少量減少鹽的攝入量，也會對人們的健康有巨大的好處。
