### Can Cranberries Help Prevent Urinary Tract and Stomach Infections? Cranberries, those small red berries often found in juices and baked goods, have been traditionally used to prevent urinary tract infections (UTIs) and other ailments. But do they really work? #### Urinary Tract Infections Several studies, some sponsored by juice manufacturers like Ocean Spray, suggest that cranberry juice can help prevent UTIs, especially in people who get them frequently. The idea is that cranberries might stop bacteria from sticking to the sides of the urinary tract. However, it's important to note that cranberries are not effective in treating an existing UTI. In 2020, the FDA allowed makers of cranberry dietary supplements to claim that there is "limited" evidence supporting their use in preventing recurrent UTIs. Similarly, cranberry juice can be labeled to say that the evidence is "limited and inconsistent." #### Stomach Infections Cranberries might also help prevent stomach infections caused by H. pylori bacteria, which can lead to ulcers. Some research suggests that cranberries could slow the buildup of dental plaque as well. #### Other Benefits Cranberries are rich in antioxidants, which protect cells from damage. Some lab studies indicate that cranberries might have anticancer effects on cells, but it's not clear if they help people with cancer. People also take cranberries for various other conditions like arthritis, eczema, and gout, although there's no strong evidence to support these uses. #### How to Consume Cranberries There is no standard dose for cranberries. Some studies have used half an ounce of cranberry juice twice a day to prevent recurrent UTIs, while others have used 600-800 milligrams of cranberry supplement capsules daily. Cranberries are widely available in many forms: fresh, frozen, dried, and sweetened. They are also found in products like juice, jelly, sauce, baked goods, and tea. While cranberry juice is generally safe, it's best for children or pregnant and breastfeeding women to consult a doctor before using cranberries for medical purposes.
