UTIs and kidney problems run riot in my family.
I've heard lots of half-hearted advice that cranberries & cranberry juice help renal/urethral health. I can personally attest that cranberry juice relieves UTIs a treat.
But can anyone tell me how? I've heard all kinds of clever-sounding guff, from pH levels, to the molecular structure of cranberries somehow "grabbing" red blood cells in the bladder / kidneys. Being small of brain and large of bladder, I need some guidance.
quote: One of the major health benefits attributed to the ingestion of cranberry juice is the maintenance of urinary tract health. Traditionally, the juice was thought to cause acidification of the urine resulting in a bacteriostatic effect. However, recent research has demonstrated that a bacterial antiadhesion mechanism is responsible. Proanthocyanidins with unique molecular structures have been isolated from cranberry fruit that exhibit potent bacterial antiadhesion activity. Little is known about the bioavailability and structure-activity relationships of cranberry proanthocyanidins. Data on how certain structural features of the molecules can influence bioactivity and bioavailability are reviewed

Thank you Rhiandmoi - so to paraphrase, first it was though that cranberry juice changed the pH level in the bladder, but later discovered that the molecular structure particular to cranberry fruit prevent bacteria from "taking hold" in the bladder - and it's not yet known quite how.
I am so pleased that the molecular explanation is the latest one, it sounds much more impressive than just a change in pH levels.
Also particularly reassured that my doctor isn't making it up as she goes along
