Urinary tract infections (UTIs) are common—especially for women—and antibiotics remain the gold-standard treatment for active infections. Still, what you eat and drink between infections can support urinary tract health. The fruits below won’t cure a UTI, but adding them to a balanced diet may help reduce risk of future episodes and support overall wellness.
Cranberries: Anti-Adhesion Power
Cranberries are the best-known fruit for UTI prevention. They’re rich in A-type proanthocyanidins (PACs), plant compounds that make it harder for E. coli—the most common UTI culprit—to latch onto the bladder wall. Less bacterial “stickiness” may mean fewer opportunities for an infection to take hold.
- How to use: Choose unsweetened 100% cranberry juice, low-sugar cranberry blends, cranberry capsules, or dried cranberries in moderation.
- Good to know: Evidence is strongest for preventing recurrent UTIs, not treating active ones. If you take warfarin, talk to your clinician—cranberry may interact.
Blueberries: Antioxidant Support
Blueberries deliver anthocyanins and other antioxidants that help temper inflammation and support immune defenses. They’re also a relative of cranberries and contain smaller amounts of PACs.
- How to use: Toss fresh or frozen berries into yogurt, oatmeal, or smoothies for a fiber-rich, low-sugar boost.
Pineapple: Bromelain for Comfort
Pineapple contains bromelain, an enzyme with anti-inflammatory properties that may ease tissue irritation. It’s not a UTI remedy, but can complement hydration and a produce-forward diet.
- How to use: Enjoy fresh pineapple or add a few chunks to a fruit salsa. Choose whole fruit over canned syrupy versions.
Watermelon: Hydration Helper
Flushing the urinary system is key to diluting urine and washing away bacteria. Watermelon is mostly water, making it a tasty way to increase fluid intake.
- How to use: Eat chilled slices, blend into a no-sugar slushie, or cube into a mint-lime salad.
Kiwi: Vitamin C for Immune Tone
Kiwi is packed with vitamin C, which supports immune function. Adequate vitamin C may also make urine less welcoming to bacterial growth.
- How to use: Pair kiwi with yogurt or cottage cheese for a protein-plus-vitamin C snack.
Smart Add-Ons & Everyday Habits
- Hydrate consistently: Aim for pale-yellow urine throughout the day; water and herbal teas are your best bet.
- Consider D-mannose: A simple sugar found in cranberries and other fruits that, in supplement form, may reduce recurrent UTIs for some—ask your clinician if it’s right for you.
- Prioritize fiber & gut health: Vegetables, legumes, and fermented foods (e.g., yogurt with live cultures) support a healthy microbiome, which may indirectly benefit urinary health.
- Bathroom habits: Don’t hold urine for long periods; urinate after sex; wipe front-to-back.
Who Should Be Cautious
- Diabetes or poor circulation: Tight glucose control and clinician guidance are essential; some fruits and juices add sugars.
- Kidney stones: If you’re prone to oxalate stones, discuss portions of high-oxalate fruits with your provider.
- Fungal infections or sensitive skin: Limit added sugars; focus on whole fruits over sweetened juices.
- Infants/toddlers: Fruit purées can be part of a healthy diet, but UTI prevention/management should always be guided by a pediatrician.
Fruits like cranberries, blueberries, pineapple, watermelon, and kiwi can support urinary tract health as part of a balanced, hydration-forward diet—but they don’t replace professional care. If you have UTI symptoms (burning, urgency, frequent urination, pelvic pain, fever, or blood in urine), see a healthcare provider promptly for diagnosis and antibiotic treatment when indicated.
