Superfood #4: Cranberries (The One Everyone Forgets)
Cranberries contain unique A-type proanthocyanidins that help maintain a healthy urinary tract environment. A meta-analysis in Advances in Nutrition confirmed regular cranberry consumption supports urinary health without added sugar.
Choose fresh or frozen berries, unsweetened juice, or dried without added sugar. Even ½ cup daily makes a difference.
Bonus Mention: Red Apples (The Perfect Daily Snack)
Apples are high in pectin, a soluble fiber that supports healthy cholesterol and blood sugar levels – both important for long-term kidney health. Studies show their quercetin content provides additional antioxidant benefits.
Eat one medium apple with skin daily. Their natural low potassium makes them ideal.
