The cranberry is perhaps best known for its role in preventing UTIs, especially for those with recurrent infections. The high level of proanthocyanidins (PACs) in cranberries helps reduce the adhesion of certain bacteria to the urinary tract walls, in turn fighting off infections.
The polyphenols in cranberries may reduce the risk of cardiovascular disease (CVD) by preventing platelet build-up and reducing blood pressure via anti-inflammatory mechanisms.
Cranberries are beneficial in slowing tumor progression and have shown positive effects against prostate, liver, breast, ovarian, and colon cancers.
The same proanthocyanidins in cranberries that help prevent UTIs may also benefit oral health by preventing bacteria from binding to teeth.
