In that 2001 study, for example, the alkaline diet raised the subjects' urine pH by an average of 1. 02 units.

例如在 2001 年的那项研究中，碱性饮食将参与者的尿液酸碱值平均增加了 1.02 个单位。

But after 4 days on the alkaline diet, while the subject's pee was noticeably less acidic the average blood pH only went up 0. 014 units on average.

但是经过四天的碱性饮食之后，虽然参与者的尿液含酸量明显减少，但是平均血液酸碱值只增加了 0.014 个单位。

And if that were the case, you'd think that bladder cancers would be especially susceptible to alkaline diets because urine pH can actually be influenced by what you eat.

如果真是这样的话，那么你就会认为膀胱癌尤为容易受碱性饮食的影响，因为尿液酸碱值真的会受到饮食的影响。

And despite the acid-ash hypothesis existing for half a century, there hasn't been any direct research showing that an alkaline diet or alkaline water can improve a person's health.

尽管酸-灰假说已经存在半个世纪了，没有任何直接研究表明碱性饮食或者是碱性水可以改善健康。
