软水可以安全饮用吗?Is softened water safe to drink?软化水喝起来安全吗?

很多人一说起全屋水处理净化中的软水机软化出来的水,就说软水绝对不能饮用。但是参考美国和欧洲等发达国家和地区的水处理流程和步骤,和中国的软水使用有很大的区别。

在中国,很明确的说法:软水不能饮用,只能使用于洗浴和洗衣机用水。

在美国,查了很多资料,没有发现软水不能饮用。下面看看软水是否安全在美国的两种说法。

第一种观点:

软化水仍然含有我们所需要的所有天然矿物质。它只是失去了它的钙和镁含量,并在软化过程中加入一些钠。这就是为什么在大多数情况下,软化水是完全安全的饮用。建议软化水中钠含量不超过300毫克/升。在硬度很高的区域,由于软化处理后钠含量高,所以不能用软化水来制备婴儿奶。

原文:Softened water still contains all the natural minerals that we need. It is only deprived off its calcium and magnesium contents, and some sodium is added during the softening process. That is why in most cases, softened water is perfectly safe to drink. It is advisable that softened water contains only up to 300mg/L of sodium. In areas with very high hardness the softened water must not be used for the preparation of baby-milk, due to the high sodium contant after the softening process has been carried out.

第二种观点:

软水中的钠可能对限制性食盐饮食的人有害。但是,这取决于饮食本身的严格程度。在正常饮食中,通过软化产生的额外钠是微不足道的。在极端限制性饮食中,人们既不喝硬水也不喝软水,而是脱盐或蒸馏水。最后,如果病人接受了非常严格的治疗,他应该遵照医生关于进水的指示。

原文:The sodium in softened water may be harmful to people on restrictive salt diets. But, this depends on the strictness of the diet itself. In normal dietary considerations, the additional sodium produced by softening is insignificant. In an extremely restrictive diet, one should drink neither hard nor soft water, but demineralized or distilled water. Ultimately, if a patient is on a very restricted regimen, he should follow the physician’s instructions regarding water intake.
