Regular drinking of which of the following can help prevent Urinary Tract infection (UTI)
**Core Concept**
The question is testing the concept of prevention of Urinary Tract Infections (UTIs) through dietary interventions. Cranberry juice has been studied for its potential to prevent UTIs, and its mechanism of action is thought to be related to its proanthocyanidins, which may prevent bacterial adhesion to bladder and urinary tract walls.
**Why the Correct Answer is Right**
Cranberry juice has been shown to reduce the incidence of UTIs in various studies. The proanthocyanidins in cranberry juice may prevent bacterial adhesion to the bladder and urinary tract walls by inhibiting the expression of P-fimbriae on the surface of E. coli bacteria. This reduces the likelihood of bacterial colonization and subsequent UTIs. Additionally, cranberry juice may also help to reduce the pH of the urine, creating an environment that is less favorable to bacterial growth.
**Why Each Wrong Option is Incorrect**
* **Option A:** Grape juice does not have any established benefits in preventing UTIs. While it may have antioxidant properties, it is not a known preventative measure for UTIs.
* **Option B:** Orange juice is not associated with a reduced risk of UTIs. It may provide some benefits due to its vitamin C content, but this is not specifically related to UTI prevention.
* **Option D:** Raspberry juice has not been studied extensively for its potential to prevent UTIs. While it may have some antioxidant properties, it is not a recommended preventative measure for UTIs.
**Clinical Pearl / High-Yield Fact**
It's essential to note that while cranberry juice may help prevent UTIs, it is not a substitute for good hygiene practices, such as wiping from front to back, and urinating after sexual intercourse. Additionally, individuals with recurrent UTIs may require further medical evaluation and treatment.
✓ Correct Answer: C. Cranberry juice
