Drinking Purple Grape Juice may also
help with Urinary Tract Health |
|

Some ten million Americans suffer from
urinary tract infection—most of them women. And for those who drink
cranberry juice to try to avoid these painful infections, laboratory
tests suggest they may now have a new option—purple grape juice. |
|
Scientist:
|
More and more Americans are drinking
purple grape juice to maintain their heart health. Now people
concerned with urinary tract health may have another good tasting
option. |

In this study, the compounds found in
purple grape juice were as effective as those found in cranberry
juice in blocking the bacterial adhesion that is thought to
contribute to urinary tract infections. |
|
Scientist: |
UTI, or urinary tract infections, are
caused when e. coli bacteria adheres to the wall of the bladder and
urinary tract. We extracted a class of compounds known as
proanthocyanidins from purple grape juice and from cranberry juice
and, in cell culture tests, these compounds from both the juices
worked equally well in blocking bacterial adhesion. |

The study, sponsored by Welch's, was
designed to replicate previous cell culture research on cranberry
juice compounds and urinary tract health. And, since purple grape
juice is also "heart healthy", maybe it's time to drink up. This is
Rona McDonald reporting. |
