Foods which may increase symptoms because they contain the natural chemical tyramine include wine, beer, cheese, nuts, yogurt, bananas, soy sauce, chicken livers, raisins, sour cream, avocados, canned figs, corned beef, beans, brewers’ yeast, and chocolate. Beside that allergic food should avoid because they may aggravate the disease condition sometime. However some patients with IC also have noticed a worsening of symptoms after taking products containing artificial sweeteners. It is also advised for betterment of patients may try eliminating such products from their daily diet and, if there is a reduction of symptoms, they can reintroduce them one at a time to determine which product seems to be aggravating their symptoms.
