Patients with interstitial cystitis find that modifying their diet helps to reduce symptoms or avoid symptom attacks. Information collected by the Interstitial Cystitis Association (ICA) suggests that the control of symptoms with a modified diet varies from person to person, a finding that is also consistent with our clinical patients’ experiences. Although there is some experience and advice on diet for people with interstitial cystitis to follow, finding the right diet for you requires a lot of personal effort to adjust and experience, which is sometimes a long process and requires a lot of self-control, as any kind of habit adjustment is never easy. Diet in general: acidic foods, pickled products, smoked products and foods and beverages that are too stimulating are used sparingly or not at all. Now I will summarize the information I have seen combined with the experience of clinical patients and list the foods that should be avoided as follows: cheese, yogurt, chocolate, soy products, citric acid, coffee tomatoes, onions, peppers, ginger products, vinegar, sauces (including homemade soybean paste) sour apples, apricots, citrus, grapes, peach, pineapple, plums, sour grass, acid aged, canned, cured, processed or smoked meat and fish products. Salted beef and meat products containing nitrates and nitrites Alcoholic beverages (including beer and liquor), carbonated beverages such as soda, coffee or strong tea, sour fruit juices, especially citrus or sour date juice Of course each individual’s diet is not quite the same, and we hope that each patient will be able to figure out the right diet for him or her in order to reduce symptoms and avoid recurrence of interstitial cystitis.
