蔓越莓汁能帮助泌尿系统感染吗?

露易丝:我被诊断出肾脏感染，引起了泌尿系统感染，这在女性中很常见。我一直被告知的一件事是喝大量的蔓越莓汁，以帮助我在未来防止水感染。我只是想知道这背后是否有科学依据，还是只是无稽之谈。

Chris -人们对此进行了研究有人认为蔓越莓汁的作用是，它会被过滤到尿液中，它会改变尿路表面的一些分子。当有人尿液感染时，通常是大肠杆菌——我们的老朋友大肠杆菌。这是一种爬错地方的肠道细菌。它附着在你的尿道壁上，通过表达一种他们讽刺地称之为“毛杆菌”的东西来做到这一点。这些是有效的分子抓钩，使细菌具有粘性。有证据表明，蔓越莓汁可能会给你一种解剖学上的特氟龙，这样你就会变得有点滑，大肠杆菌就不能附着在上面了。实际上，现在还没有定论。人们对此做了很多研究。一些试验表明它是有效的。其他试验表明它并不有效。 So, at the moment, I don't think people judge this to be adequate evidence base for us to say this will prevent you getting a UTI. What's certainly and arguably true though is, if you drink plenty and you pee plenty, you will therefore increase the odds of detaching the microbes from where they shouldn't be and flush them out. That means that you're less likely to have a urine infection in the first place. Getting dehydrated, especially on hot days, when you can get an overgrowth of the bugs because you're not washing them out as frequently, that's a big risk factor. So, I would urge you, if you are at risk of having UTIs, which can happen because it's very common, then drinking plenty regardless of what's in the drink you drink - within reason (!) - will probably help.
