The Benefits of Dried Cranberries: A Health Perspective
The unique nutritional composition of dried cranberries translates into a wide array of potential health benefits. From urinary tract health to heart health and beyond, these little berries pack a powerful punch.
Urinary Tract Health: Preventing UTIs
Cranberries are perhaps best known for their ability to help prevent urinary tract infections (UTIs). This benefit is primarily attributed to a specific type of polyphenol called A-type proanthocyanidins (PACs). These PACs interfere with the ability of bacteria, particularly E. coli (the most common cause of UTIs), to adhere to the walls of the urinary tract. By preventing bacterial adhesion, PACs help to reduce the risk of infection. While dried cranberries can contribute to UTI prevention, it’s important to note that the concentration of PACs may vary, and consuming large amounts of juice or supplements specifically formulated for UTI prevention may be more effective in some cases.
