May help to fight off urinary tract infections (UTIs). They reduce the ability of certain E. coli bacteria to adhere and penetrate the walls of the bladder.
In about half the cases of UTIs, the E. coli responsible have special little hairy tips called P fimbria. The bacteria use their fimbria to attach themselves to the bladder so that they can multiply and cause an infection. That’s where cranberries–which contain a group of chemicals called proanthocyanidins—come in action. They bind to the P fimbria of the E. coli and hinder them so that they are unable to stick to the walls of the bladder. As a result, the E. coli is flushed out through the urine instead of causing an infection. And because cranberries remove the bacteria and don’t kill it , there’s less chance for the E. coli to become resistant.
It’s imperative that those who are prone to UTIs eat cranberries or drink cranberry juice on a daily basis, because once the bacteria are able to adhere to the wall, the infection sets in, and the cranberries can’t help at that point.
It’s probably best to use cranberry products twice a day if you are prone, as the effects of the cranberries wear off after about 10 hours.
You should also be diligent about drinking lots of fluids in order to flush the bladder out on a regular basis. Citrus fruits and fresh vegetables high in vitamin C are also good, as they help boost the body’s immune system and germ-fighting abilities. Coffee, tea and other caffeinated beverages should be avoided, as well as alcohol. Be sure to complement your diet with plenty of foods rich in vitamin B, such as fortified cereals, lean proteins, asparagus, almonds and bananas, as they all assist the body in the digestive process and in converting food to energy, which your body will need if it’s working to fend off a UTI.
