Generally, people with interstitial cystitis/painful bladder syndrome do not have problems tolerating bread and baked goods. Although there is a trend toward gluten-free foods and some bladder patients say that avoiding gluten has helped their symptoms, the great majority of IC patients consume most breads, cereals, and baked goods without issue. Read labels to avoid products that contain high levels of added vitamins. Some patients may also be affected by high levels of preservatives. Individualization via trial and error is the key.
