The interstitial cystitis diet eliminates acidic foods and drinks that can aggravate the bladder. Caffeine, acidic fruits and juices, and processed tomato products are prohibited, while simple dishes with limited seasonings and dairy products (excluding certain cheeses) are allowed.
Interstitial cystitis is a condition that causes pain or pressure in the bladder, making urination difficult or painful. Although diet hasn’t been shown to actually cause the condition, certain foods can make current symptoms worse. People suffering from the condition may be advised to follow the interstitial cystitis diet, which eliminates acidic foods and drinks that can aggravate the bladder.
Caffeine is one of the most common ingredients that are prohibited in the interstitial cystitis diet. Coffee and certain teas, such as green tea, contain high levels of caffeine, which acts as a natural diuretic. A diuretic is a substance that causes the body to produce more urine than normal. Increased urination can further irritate the bladder and cause additional pain for people with this condition. Certain teas, such as herbs or mint, have not been found to aggravate symptoms and are allowed in the diet.
Another item that is not allowed in the interstitial cystitis diet is acidic fruit and fruit juices. Fruits, especially cranberries, oranges, grapefruit, and other citrus fruits, contain high levels of acid and can be irritating to the bladder. Apples and apple juice may be allowed because the sweetest apples do not usually contain much acid. Other common low-acid fruits that can be eaten in the eating plan are blueberries, pears, and mangoes.
The interstitial cystitis diet generally calls for simple dishes with limited seasonings. Commercially prepared sauces, such as gravy or barbecue sauce, are generally not recommended on the diet because they typically contain acidic ingredients such as vinegar, wine, or citrus juices, for flavor. In the diet, meat dishes in particular should be seasoned as lightly as possible because spicy sauces, marinades, and seasonings can cause symptom flares. Most meat, poultry, and seafood are allowed on the diet, although preserved meats, such as salami or pepperoni, can contain irritating ingredients and should be limited.
Dairy products can generally be eaten freely on the interstitial cystitis diet, with the exception of certain cheeses. Soft, mild cheeses, such as Monterey, mozzarella, and cottage cheese, can be consumed without aggravating the bladder. Ripe, hard cheeses tend to contain enzymes that can make interstitial cystitis symptoms worse. Cheeses that should be avoided in the diet include brie, cheddar, and gouda.
Although most natural foods like fruits and vegetables are recommended in the diet, one of the main exceptions is processed tomato products. Commonly prohibited products are tomato paste and tomato sauce. The body seems to absorb more acid from tomatoes after they’ve been processed compared to fresh tomatoes.
