Why is cranberry juice recommended for bladder infections?

Answer:

Well, both the cranberry and blueberry have a substance called tannin which prevents bacteria called Escherichia coli to attach to the inner wall of the urinary tract. It is a tube from the bladder which runs to the outside ureters (tube going to the bladder and kidneys). The tannins would prevent the bacteria from forming or binding to the urinary tract resulting it to be washed out of the bladder when urinating.

I often have a cranberry juice since it can also help prevent prostate cancer. Either way, drink up on cranberry juice and make a toast to yourself knowing you cant go wrong with this drink!
