Tannins can be found in a variety of foods and beverages. Fruits and vegetables containing tannins that people with pemphigus should avoid are bananas, raspberries, blackberries, apples, pears, cherries, mangoes, cranberries, persimmons, grape skins, avocados and eggplants.

Other tannin triggers are black walnuts, kola nuts, cocoa seeds, black pepper, garlic, ginger, cumin, rosemary, coriander, ginseng, yucca and arrowroot.

Coffee, some teas, soft drinks, beer and wine are among the drinks that contain tannins and could trigger pemphigus.

Foods Containing Isothiocyanates

Isothiocyanates, which are mustard oils found in many types of vegetables, could cause a pemphigus outbreak in people with the disorder. Vegetables in this class are broccoli, cauliflower, cabbage, turnip, mustard, brussel sprouts, winter cress, radish and horseradish.

Some seasoned sauces contain synthetic mustard oils for flavoring, which could irritate mucous membranes in people with pemphigus.

Foods Containing Thiols

Onions, garlic and leeks are thiol-containing foods that can trigger an outbreak or flare-up of pemphigus. These foods are part of the Allium group, which also includes chives and shallots. Foods containing thiols may cause blisters and should be eliminated from the diet if they are suspected as a trigger of pemphigus.

Foods Containing Phenols

Phenols are another trigger for pemphigus and can be found as cinnamic acid in fruit juices and flavorings in ice cream, baked goods, candy, condiments and beverages. Pinene is another common type of phenol that is found in potatoes, tomatoes, bananas, mangoes and black pepper.

Phenols can also be found in foods that are smoked or have a smoked flavor, and in milk and other dairy products from cows that feed on cottonseed.
