Is it true that cranberry juice helps prevent urinary tract infections (UTIs)?

Cranberry juice has been widely studied for its potential role in preventing urinary tract infections (UTIs). Research indicates that cranberry products, such as cranberry juice or capsules, may help reduce the risk of UTIs by preventing bacteria from adhering to the urinary tract lining. This action primarily involves compounds called proanthocyanidins, which are found in cranberries.

The misconception that cranberry juice is ineffective stems from studies showing variable results in certain populations, particularly when considering factors such as dosage and duration of consumption. While it doesn't guarantee UTI prevention for everyone, it is still accepted in many contexts, especially for individuals who are prone to recurrent urinary tract infections.

While cranberry juice can be helpful for some, especially those who have a history of UTIs, it is not universally effective for all individuals or all demographics. Additionally, cranberry juice should not be relied upon as a sole preventive measure; maintaining good hydration and practicing good urinary health are essential. Overall, the statement that cranberry juice helps prevent UTIs can be deemed true for specific populations and situations, making the response to the question less definitive than a simple true or false.
