Question: How can my diet help prevent or relieve kidney infections?
Answer: Experts don’t think your diet can help prevent or treat kidney infections. Some research says that cranberry products may help prevent urinary tract infections (UTIs), but there isn’t enough evidence to be sure.2

For safety reasons, talk with your health care professional before using dietary supplements, such as vitamins, or any complementary or alternative medicines or medical practices.
Question: Can drinking liquids help prevent or relieve kidney infections?
Answer: Drinking enough liquids can keep you hydrated and help prevent or relieve UTIs, including kidney infections. Water is best.
