Answer

Foods that have been implicated in aggravating symptoms of interstitial cystitis and, in the opinion of some authors, can precipitate symptomatic flares, include the following:

  • Coffee
  • Alcohol (beer, red wine, white wine, champagne)
  • Carbonated beverages
  • Monosodium glutamate (MSG)
  • Artificial sweeteners
  • Tomatoes
  • Vinegar
  • Citrus
  • Spicy foods
  • Chocolate
  • Cranberry juice
  • Particular fruits and vegetables

Avoiding these food items or substituting other food items is often advised. In a 2011 study, use of calcium glycerophosphate, sodium bicarbonate, or both before eating foods that triggered symptoms showed a trend toward improvement of symptoms. [64]
