Interstitial cystitis is a bladder condition that causes recurring pain and discomfort in the bladder and the entire pelvic region, resulting in symptoms such as frequent urination, painful urination and pain during sexual intercourse. The causes of IC are poorly understood, and although dietary changes are not proven to relieve IC, many professionals suggest that limiting specific foods, including processed proteins, many help reduce symptoms. As with any nutrition plan, consult your doctor or a nutritionist prior to making any major dietary changes.
Diet Modification and IC
The National Kidney & Urologic Diseases Information Clearinghouse notes that dietary strategies are not proven to treat IC. The Interstitial Cystitis Association, however, suggests that some specific foods may trigger painful IC flares based on patient anecdotes, and eliminating these foods may help certain individuals. Patients with IC can elect to follow a special diet and track their own personal response to specific protein sources to see if this nutritional approach helps reduce pain and discomfort.
Proteins to Avoid
Patients diagnosed with IC should avoid all cured and processed meats including hot dogs, corned beef, canned meats, and sausage. Soy products, sharp cheeses, lunch meats, and some nuts, such as hazelnuts, pecans, and pistachios should also be avoided. Processed protein foods with high amounts of salt and preservatives are more likely to trigger painful IC flares.
Healthy Proteins and IC
Whole proteins with few preservatives, such as chicken, turkey, lean beef, fish and eggs are all considered less offensive protein sources for people with IC. American or cheddar cheese cream cheese, cottage cheese, milk, and milk substitutes are also typically considered to be bladder-friendly sources of protein. Peanut butter and whey protein powders can also be used to supplement protein in individuals who do not eat meat or dairy.
Expert Insights
The Interstitial Cystitis Association notes that an IC diet often has highly individualized results. Patients should track their diet carefully and attempt to find any patterns in specific proteins that seem to cause flares of bladder pain. Many patients are likely to find the best success cutting back on all cured and processed proteins in order to see whether these restrictions help reduce bladder pain and discomfort. Patients should keep a food diary and avoid any proteins that seem to trigger repeated or intense discomfort.
