6. Avoid: Tomato products

Tomatoes are acidic; hence their bladder-irritating quality. The effect varies by individual, but if you're vulnerable, try cutting out all tomato forms, including sauces, paste, juice, spaghetti sauce, taco sauce, and salsa.

Better: Substitute mushrooms and other vegetables, a thin white sauce, beans, or other ingredients wherever you'd use tomatoes or tomato sauce.
