Cranberries May Help Fight UTIs—but Do They Really Work for Everyone?
Cranberries are often praised for their health benefits, particularly in preventing urinary tract infections (UTIs). Recent studies also suggest they may improve heart health, memory, and even reduce cancer risks. Yet, while these small red fruits offer advantages, they also come with some risks for certain individuals.
Cranberries have long been linked to preventing UTIs. Compounds called proanthocyanidins stop bacteria from clinging to the urinary tract lining. Research supports this effect, especially in women with recurrent UTIs and children. A 2012 Cochrane review found cranberry products may help, though trial quality varied. A 2016 study by Gupta et al. compared cranberry capsules to placebos in young women but saw no clear reduction in UTIs. Meanwhile, a 2018 meta-analysis by Jepson et al. confirmed modest benefits for women with repeat infections, though results differed across studies.
Cranberries offer a range of potential health benefits, from preventing UTIs to supporting heart and immune function. However, their effects vary, and some people should consume them with caution. While supplements provide a concentrated form, whole cranberries remain the best option for broader nutritional value.
