Foods To Avoid For Nasal Polyps

MSG And Sulfites

Sulfites are preservatives that are frequently used to delay the growth of mold on food. They also increase freshness. Sulfites may be referred to as sulfurous acid, sulfites, and sulfur dioxide, among others. Common foods that contain sulfites include soup mixes, pickled foods, dried fruit, potato chips, wine, vegetable juice, beer, apple cider, and condiments. Frozen shrimp, guacamole, maraschino cherries, lemon juice, and canned vegetables also contain sulfites. Monosodium glutamate (MSG) is a flavor enhancer often included in canned vegetables, processed meats, and canned soups. 

Both MSG and sulfites are common sources of sensitivity in individuals when they are consumed. Much like the white blood cell cascade that occurs in individuals who are allergic to soy, the same immune response can occur with sulfites and MSG. The allergic reaction contributes to the increased amount of mucus in the nasal passages. This will increase the severity of nasal polyp symptoms.
