Cystitis is a common urological condition that includes acute and chronic cystitis, bladder leukoplakia, glandular cystitis, and interstitial cystitis. For patients there are some experiences and recommendations about diet to follow, but to find the right diet for them requires a relentless personal effort to adjust and experience, which is sometimes still a long process and requires a lot of self-control, because any kind of habit adjustment is never easy. Diet in general: Chinese medicine theory says that foods that can lead to fire, spicy, barbecue, seafood, acidic foods, pickled products, smoked products and foods and drinks that are too stimulating to eat as much as possible. Now I will see the information combined with the clinical patient experience for a summary list of foods that should be avoided as follows: cheese, yogurt, chocolate, soy products, citric acid, coffee. Tomatoes, onions, peppers, ginger products, vinegar, sauces (including homemade bean paste). Sour apples, apricots, citrus, grapes, peach, pineapple, plums, sour grass, sour cherries. Aged, canned, cured, processed or smoked meat and fish products, corned beef, and meat products containing nitrates and nitrites. Alcoholic beverages (including beer and liquor), carbonated beverages such as soda, coffee or strong tea, sour juices, especially citrus or tart date juice. Of course, each person’s diet is different, and we hope that each patient will be able to figure out a diet that works for him or her to reduce symptoms and avoid recurrence of cystitis.
